Gyroplanes Blade Resonance article in December 2008 issue of ROTORCRAFT by Martin Hollmann. Free download, 4.7 MB pdf. Letter from Sportster pilot: Marty, I am thankful I learned to fly gyros in your Sportster design. Jerry Blaskey. Letter from SAA: I read the comments from various people relative to the use of the horizontal stabilizer and of course the need for one. It certainly makes sense in reading it and in your comments as well as those of others. Paul Poberezny, Letter from Piasecki Aircraft Co: Your book “Modern Gyroplane Design” is simply a pleasure to read and you have made a very tough subject very understandable.
In helping to explain our performance numbers in our solicitations, we would like to include a copy of your book as supporting documentation for one of our reports. We feel strongly that members of the board who will be evaluating our technical report could make great use of your text. We are quoting it routinely in the body of out text. Chuck Jarnot. Unfortunately for me I put my gyro interests on hold for a while since the gyro community seemed to be confused about the horizontal tail issue. Had I studied your materials harder, I would not have needed to. I am building on a fixed wing but can also start the Bumble Bee as it doesn’t require much hanger room.

Flight reports of the Sportster and Bumble Bee are presented in. Sharepoint update list item power shell. For those interesting in designing gyros, the book is the only book in the world on this subject. The Sportster is the word’s first two place, experimental, gyroplane. It first flew in 1974.
The Sportster is powered by a 160 hp Lycoming 0-320 engine. It is enclosed and designed to carry two large people. Seating is side by side with dual controls for flight training.
Many Sportsters have been built and hundreds of people have learned to fly in the Sportster or derivatives of the Sportster. Structure is bolt together aluminum. The Sportster has the safest flight history of any gyroplane in the world. Price for well detailed plans is $535.
Plans include drawings for tow hitch, prerotator, and rotor blades. For a free copy of Hollmann’s Master Thesis, “DESIGN OF THE ULTRALIGHT TWO PLACE GYROPLANE,” Florida Technical University, FL, 1974.
File, Seth Hedstrom tells of his 1,600 km flight in his Sportster in the upcoming issue of PRA’s Rotorcraft magazine. This 2 place gyroplane designed by Martin Hollmann was built by Helga Swenson in Sweden about 12 years ago and Seth has been made a number of improvements to it. On his trip he averaged a TAS of 81 mph on the 13 hr flight and burned 9.2 gph fuel. At the airports he landed many people came to see his Sportster. (reminds me of when I fly my Sportster. I have had as many as 20 aircraft wait for me to take off) Congratulations Seth on a great job.
Martin Hollmann The recent picture of the Sportster on the left was taken at the South County Airport, CA Fly-In, on May 5, 2001. A number of improvements have been made which include a new Matco nose wheel with a hydraulic brake and a better rotor blade adjustment hub. The last time the Sportster was flown was 10 years ago. The Sportster first flew in 1974. It has been copied by others and is also known as the Shadow and the Avenger. For a free copy of the Sportster Stress Analysis, 12.8 MB PDF file.

This is before she met Dick Rutan. Jeana joined came along to the Chino Airshow to help me promote the Sportster. There she met Dick and the rest is history. But Jeana loves helicopters, gyroplanes, horses, and yes-airplanes. The Bumble Bee was designed, built, and flown by ADI in 1983. It is the world’s first ultralight gyroplane. The Bumble Bee is one of the few ultralight gyroplanes on the market.
It uses a prerotator to spin the rotor blades up to 300 rpm on the ground. Once the blades are up to speed, the take off distance is 230 feet on a calm day. It is powered by a 40 hp Rotax or Kawasaki engine. Flight speed ranges from 15 to 70 mph. Construction is bolt together aluminum tubes. Price for plans is $250. Plans include prerotator, blades, and trailer modification to transport aircraft.

For a free copy of the BUMBLE BEE PERFORMANCE AND STRESS REPORTS. 2.2 MB.pdf file, The Bumble Bee at Hollister, CA in 1983. Plans are rotor blades are available for the Bumble Bee. This gyroplane is the first ultralight gyroplane with a prerotator and instrument panel.
Others such as the Honey Bee and the Gyro Bee are Bumble Bee clones. On the left is Martin flying the prototype Bumble Bee and in the middle is Allen Tatarian test flying the first Bumble Bee at Hollister, CA. Murray Goossen from Canada just (2008) sent a letter stating that he now has 650 hrs on his BB.
He writes: The machine is now settling in as far as maintenance is concerned. Their are things that wear but this is normal. The nose wheel lock is a little awkward. Rotorhead and pre-rotator very good – the belt tensioner pivot was beefed up some time ago about 70 TT. Its a little loose now and will need some attention. Empennage is trouble free. Brakes were changed to Gerdes hydraulic before the first flight and remain unmodified.
The throttle quad was doubled up to inlcude carb heat, is twice as fat and works well. Your designs have a simple elegance to them and it appreciated. Regard – Murray Goossen. Martin, Over the last few months, I have taken advantage of all the information one can find on gyrocopters and the industry over the last thirty plus years. I have read your publications, books by Paul Bergen Abbott, PRA magazine, and many of the comments on the web’s Rotary Wing Forum.
I have found much good information as well as opinions, egos, rivalries, self-appointed gurus, etc. But, through it all, you are the only one in the past 40 years that has written a book specifically on small gyroplanes and has designed, built and flew both of them, plus still offering a class on gyroplane design.
This puts you in a unique position to further advance the gyroplane into the 21st century, which leads me to why I am writing this email to you. As a new gyroplane enthusiast, you have the only plans-built, two-place, side by side enclosed gyro on the market today. Yes, there is the SparrowHawk, RAF 2000 and Air Command, but these are kits.
The SparrowHawk is $50,000 with a used engine, the RAF 2000 is dangerous without modifications, and the Air Command is underpowered and not enclosed. Sportcopter in Oregon is coming out with a new side by side model, for a whopping $60,000 without the engine. Many of us don’t want, or cannot afford a $50,000 to $100,000 gyroplane. EAA and PRA have moved away from the basics of building from plans. I have built two airplane fuselages out of 4130 tubing and enjoy working in that material.

Plus, the new generation of gyroplane pilots are demanding stable, safe machines. I would rather have steel tubing around me than composite. I want to build a Sportster that combines old technology with what we now know about stability, safety, and engine and material choices for the homebuilder. I believe that many more like myself are craving for a plans-built, two-place, side by side enclosed gyrocopter that incorporates the new design parameters and selection of materials. Rich Nuttall Martin Hollmann designed the Kerry Gyroplane in June 1989 as shown on the left below. Many years later, Don Farrington produced a gyroplane called the Twin Star.
As can be seen, the empennage of the Twin Star was a copy of the Kerry Gyro.

A gyrocopter is an easy-to-fly aircraft that’s remarkably maneuverable. Unlike a helicopter, a gyrocopter doesn’t need a tail rotor, which enables you to fly one with a joystick. Although flying a gyrocopter can take a while to master, building one is not so difficult. Below is a short guide that will assist you in building your own gyrocopter. Step 1 – Choose the Design First, you need to determine the design that you want to use for your gyrocopter because the frame will depend on it.
There are designs that are meant to work efficiently, and there are also designs that are made with ease of construction in mind. You might want to check with a few gyrocopter enthusiasts and pilots to get an idea of the pros and cons of various designs. Step 2 – Purchase Panel Material Once you have the design picked out, you will be able to identify the exact length and the sizes of squared aluminum or galvanized steel sheets and the number of bolts and screws that you will need. Most plans for do-it-yourself gyrocopters include this information, so it should not be difficult to determine. You can even purchase gyrocopter kits, which already contain all the parts for easy assembly.
If you don't purchase a kit, you will need to visit a machine shop and have the metal cut to exact measurements. Step 2 – Planning, Measuring, and Drilling Holes When your squared aluminum, or, is ready, you can now start to drill. Use a sharp hand drill and flat-steel drilling guides to ensure more accurate depth cuts. Refer to the Manual The distance between holes should be exact and follow instruction manual guidelines precisely.
While you are drilling, continue to refer to the manual often to ensure your measurements are precise when creating the gyrocopter frame. Ensure Straightness Also, make sure the drill holes are completely straight and level, using a chalk line and a level. You should spend more time measuring and marking the drill holes than you should drilling them. Step 3 – Assembling Square Aluminum or Galvanized Steels Connect all the square aluminum properly with screws and bolts. Use Safety Wire To keep the bolts from jumping out of the hole, you can use safety wire.
This wire will provide additional protection by serving as backup support, and it also helps to strengthen your gyrocopter frame. Airframe vibration naturally occurs after the copter is in the air, and this vibration can loosen screws and bolts. However, with safety wire attached to the bolts, you can minimize this risk. Once you've finished building the frame, you can begin constructing the rest of your gyrocopter and.
Autogyro in flight. An autogyro (from αὐτός + γύρος, self-turning), also known as gyroplane, gyrocopter, or rotaplane, is a type of that uses an unpowered rotor in to develop, and an engine-powered propeller, similar to that of a, to provide. While similar to a in appearance, the autogyro's rotor must have air flowing through the rotor disc to generate rotation. Invented by the Spanish engineer to create an aircraft that could fly safely at low speeds, the autogyro was first flown on January 9, 1923, at in. De la Cierva's aircraft resembled the of the day, with a front-mounted engine and propeller in a to pull the aircraft through the air. Under license from Cierva in the 1920s and 1930s, the Pitcairn & Kellett companies made further innovations.
Late-model autogyros patterned after 's and 's designs feature a rear-mounted engine and propeller in a. The term Autogiro was a of the, and the term Gyrocopter was used by E. Burke Wilford who developed the Reiseler Kreiser feathering rotor equipped gyroplane in the first half of the twentieth century. The latter term was later adopted as a trademark. The rotor head, pre-rotator shaft and engine configuration on a VPM M-16 autogyro An autogyro is characterized by a free-spinning rotor that turns because of the passage of air through the rotor from below.
The vertical (downward) component of the total aerodynamic reaction of the rotor gives lift for the vehicle, and sustains the autogyro in the air. A separate propeller provides forward thrust, and can be placed in a tractor configuration with the engine and propeller at the front of the fuselage (e.g., Cierva), or pusher configuration with the engine and propeller at the rear of the fuselage (e.g., Bensen). Whereas a helicopter works by forcing the rotor blades through the air, drawing air from above, the autogyro rotor blade generates lift in the same way as a 's wing, by changing the angle of the air as the air moves upwards and backwards relative to the rotor blade. The free-spinning blades turn by; the rotor blades are angled so that they not only give lift, but the angle of the blades causes the lift to accelerate the blades' rotation rate, until the rotor turns at a stable speed with the drag and thrust forces in balance.
External video on of on of in 1941 Because the craft must be moving forward (with respect to the surrounding air) in order to force air through the overhead rotor, autogyros are generally not capable of vertical takeoff or landing (unless in a strong headwind). Have shown short takeoff or landing. Pitch control is achieved by tilting the rotor fore and aft; roll control by tilting the rotor laterally (side to side). Three designs to affect the tilt of the rotor are a tilting hub (Cierva), , or servo-flaps. A provides yaw control. On pusher configuration autogyros, the rudder is typically placed in the propeller to maximize control at low airspeed (but not always, as seen in the, with twin rudders placed outboard of the propeller arc). Flight controls There are three primary flight controls: control stick, and.
Typically, the control stick is termed the cyclic and tilts the rotor in the desired direction to provide pitch and roll control (some autogyros do not tilt the rotor relative to the airframe, or only do so in one dimension, and have conventional control surfaces to vary the remaining degrees of freedom). The rudder pedals provide yaw control, and the throttle controls engine power. Secondary flight controls include the rotor transmission clutch, also known as a pre-rotator, which when engaged drives the rotor to start it spinning before takeoff, and to reduce blade pitch before driving the rotor. Collective pitch controls are not usually fitted to autogyros, but can be found on the and and the and are capable of near performance.
Unlike a helicopter, autogyros without collective pitch or another jump start facility need a runway to take off; however, they are capable of landing with a very short or zero ground roll. Like helicopters, each autogyro has a specific for safest operation, although the dangerous area is usually smaller than for helicopters. Rocket-powered autogyro So-called, actually, are placed at the tips of the rotor. The rockets are used only during takeoff and emergency landing, so they do not consume much propellant. The hydrogen peroxide rockets are light-weight, inexpensive, reliable, noisy, and transform the autogyro into an aircraft that has almost all the advantages of a helicopter (specifically ) at a fraction of the helicopter cost.
Furthermore, the engine weight and engine power may be reduced by half because a smaller engine is needed for takeoff. The and had true instead of the rockets. They were technically successful but were not mass-produced due to concerns about tipjet noise. Pusher vs tractor configuration. Montgomerie Merlin single-seat autogyro Modern autogyros typically follow one of two basic configurations.
The most common design is the pusher configuration, where the engine and propeller are located behind the pilot and rotor mast, such as in the Bensen '. It was developed by Igor Bensen in the decades following World War II, and came into widespread use shortly afterward. Less common today is the tractor configuration. In this version, the engine and propeller are located at the front of the aircraft, ahead of the pilot and rotor mast. This was the primary configuration in early autogyros, but became less common after the advent of the helicopter. It has enjoyed a revival since the mid-1970s.
History was a Spanish and aeronautical enthusiast. In 1921, he participated in a design competition to develop a bomber for the Spanish military. De la Cierva designed a three-engined aircraft, but during an early test flight, the bomber stalled and crashed. De la Cierva was troubled by the stall phenomenon and vowed to develop an aircraft that could fly safely at low airspeeds. The result was the first successful rotorcraft, which he named Autogiro in 1923. De la Cierva's autogyro used an airplane fuselage with a forward-mounted propeller and engine, a rotor mounted on a mast, and a horizontal and vertical stabilizer. Early development.
The first autogyro to fly successfully in 1923. Juan de la Cierva invented the modern autogyro (autogiro in Spanish) in the early 1920s. His first three designs (, and ) were unstable because of aerodynamic and structural deficiencies in their rotors. His fourth design, the, made the first documented flight of an autogyro on 17 January 1923, piloted by Alejandro Gomez Spencer at Cuatro Vientos airfield in Madrid, Spain (9 January according to Cierva).
De la Cierva had fitted the rotor of the C.4 with flapping hinges to attach each rotor blade to the hub. The flapping hinges allowed each rotor blade to flap, or move up and down, to compensate for, the difference in lift produced between the right and left sides of the rotor as the autogyro moves forward.
Three days later, the engine failed shortly after takeoff and the aircraft descended slowly and steeply to a safe landing, validating De la Cierva's efforts to produce an aircraft that could be flown safely at low airspeeds. Replica in Cuatro Vientos Air Museum, Madrid, Spain De la Cierva developed his model with the assistance of Spain's Military Aviation establishment, having expended all his funds on development and construction of the first five prototypes. The C.6 first flew in February 1925, piloted by Captain, including a flight of 10.5 km (6.5 mi) from Cuatro Vientos airfield to airfield in about 8 minutes, a significant accomplishment for any rotorcraft of the time. Shortly after De la Cierva's success with the C.6, Cierva accepted an offer from Scottish industrialist James G. Weir to establish the Cierva Autogiro Company in England, following a demonstration of the C.6 before the British at, on 20 October 1925.
Britain had become the world centre of autogyro development. A crash in February 1926, caused by blade root failure, led to an improvement in rotor hub design. A drag hinge was added in conjunction with the flapping hinge to allow each blade to move fore and aft and relieve in-plane stresses, generated as a byproduct of the flapping motion. This development led to the Cierva C.8, which, on 18 September 1928, made the first rotorcraft crossing of the followed by a tour of Europe.
Industrialist, on learning of the successful flights of the autogyro, visited De la Cierva in Spain. In 1928, he visited him again, in England, after taking a L.IV test flight piloted by Arthur H.C.A. Being particularly impressed with the autogyro's safe vertical descent capability, Pitcairn purchased a C.8 L.IV with a Wright Whirlwind engine. Arriving in the United States on 11 December 1928 accompanied by Rawson, this autogyro was redesignated C.8W.
Subsequently, production of autogyros was licensed to a number of manufacturers, including the in the U.S. And of Germany.
Built Mk.IV Autogiro In 1927, a pioneering German engineer, invented a combined helicopter and autogyro. The principal advantage of the Zaschka machine is in its ability to remain motionless in the air for any length of time and to descend in a vertical line, so that a landing may be accomplished on the flat roof of a large house. In appearance, the machine does not differ much from the ordinary monoplane, but the carrying wings revolve around the body. Development of the autogyro continued in the search for a means to accelerate the rotor prior to takeoff (called prerotating).
Rotor drives initially took the form of a rope wrapped around the rotor axle and then pulled by a team of men to accelerate the rotor – this was followed by a long taxi to bring the rotor up to speed sufficient for takeoff. The next innovation was flaps on the tail to redirect the propeller slipstream into the rotor while on the ground.
This design was first tested on a in 1929. Efforts in 1930 had shown that development of a light and efficient mechanical transmission was not a trivial undertaking. But, in 1932, the Pitcairn-Cierva Autogiro Company of, finally solved the problem with a transmission driven by the engine. Produced its, the first autogyro with propulsive rear motor, designed by and meant for aerial observation (motor behind pilot and camera).
It had its maiden flight on 15 December 1931. With rear push propeller (1931) De la Cierva's early autogyros were fitted with fixed rotor hubs, small fixed wings, and control surfaces like those of a fixed-wing aircraft. At low airspeeds, the control surfaces became ineffective and could readily lead to loss of control, particularly during landing.
In response, Cierva developed a direct control rotor hub, which could be tilted in any direction by the pilot. De la Cierva's direct control was first developed on the Cierva C.19 Mk. V and saw production on the Cierva series of 1934. In March 1934 this type of autogyro became the first to take off and land on the deck of a ship, when a C.30 performed trials on board the off Valencia. Later that year, during the leftist in October, an autogyro made a reconnaissance flight for the loyal troops, marking the first military employment of a rotorcraft.
When improvements in helicopters made them practical, autogyros became largely neglected. Also, they were susceptible to. They were, however, used in the 1930s by major, and by the for the mail service between the Camden, New Jersey airport and the top of the post office building in downtown. World War II. Kayaba Ka-1 The autogyro, a military version of the Cierva C.30, was used by the to calibrate the during and after the.
In World War II, Germany pioneered a very small gyroglider, the 'Bachstelze' (Water-wagtail), towed by to provide aerial surveillance. The developed the Autogyro for reconnaissance, artillery-spotting, and anti-submarine uses. The Ka-1 was based on the first imported to Japan in 1938. The craft was initially developed for use as an observation platform and for artillery spotting duties.
The Army liked the craft's short take-off span, and especially its low maintenance requirements. Production began in 1941, with the machines assigned to artillery units for spotting the fall of shells. These carried two crewmen: a pilot and a spotter. Later, the Japanese Army commissioned two small aircraft carriers intended for coastal (ASW) duties.
The spotter's position on the Ka-1 was modified to carry one small depth charge. Ka-1 ASW autogyros operated from shore bases as well as the two small carriers. They appear to have been responsible for at least one submarine sinking. Postwar developments The autogyro was resurrected after World War II when Dr., a Russian immigrant in the US, saw a captured German U-Boat's Fa 330 gyroglider and was fascinated by its characteristics. At work, he was tasked with the analysis of the British military ' gyro glider designed by expatriate Austrian. This led him to adapt the design for his own purposes and eventually market the in 1955.
Bensen submitted an improved version, the, for testing to the, which designated it the X-25. The B-8M was designed to use surplus engines used on flying unmanned. Developed a miniature autogyro craft, the, in England in the 1960s, and autogyros built similar to Wallis' design appeared for a number of years.
Ken Wallis' designs have been used in various scenarios, including military training, police reconnaissance, and in a search for the, as well as a notable appearance in the 1967 James Bond movie. Three different autogyro designs have been certified by the for commercial production: the Umbaugh U-18/ of 1965, the of 1967, and the of 1972. All have been commercial failures, for various reasons. Bensen Gyrocopter The basic design is a simple frame of square aluminium or galvanized steel tubing, reinforced with triangles of lighter tubing. It is arranged so that the stress falls on the tubes, or special fittings, not the bolts. A front-to-back keel mounts a steerable nosewheel, seat, engine, and a vertical stabilizer.
Outlying mainwheels are mounted on an axle. Some versions may mount seaplane-style floats for water operations. Bensen Aircraft B8MG Gyrocopter Bensen-type autogyros use a for simplicity and to increase visibility for the pilot. Power can be supplied by a variety of engines. McCulloch drone engines, Rotax marine engines, Subaru automobile engines, and other designs have been used in Bensen-type designs.
The rotor is mounted atop the vertical mast. The rotor system of all Bensen-type autogyros is of a two-blade teetering design. There are some disadvantages associated with this rotor design, but the simplicity of the rotor design lends itself to ease of assembly and maintenance and is one of the reasons for its popularity. Aircraft-quality birch was specified in early Bensen designs, and a wood/steel composite is used in the world speed record holding Wallis design. Gyroplane rotor blades are made from other materials such as and -based composite blades. Because of Bensen's pioneering of the concept and the popularity of his design, 'Gyrocopter' has become a for pusher configuration autogyros. Bensen's success triggered a number of other designs, some of them fatally flawed with an offset between the and thrust line, risking a (PPO or bunt-over) causing death to the pilot and giving gyroplanes in general a poor reputation – in contrast to Cierva's original intention and early statistics.
Most new autogyros are now safe from PPO. 21st-century development and use. Hawk 4 provided perimeter patrol during the 2002 Winter Olympics. In 2002, a 's provided perimeter patrol for the Winter Olympics and Paralympics in Salt Lake City, Utah. The aircraft completed 67 missions and accumulated 75 hours of maintenance-free flight time during its 90-day operational contract.
Worldwide, over 1,000 autogyros are used by authorities for military and law enforcement, but the first US Police authorities to evaluate an autogyro are the, police, on a $40,000 grant from together with city funds, costing much less than a helicopter to buy ($75,000) and operate ($50/hour). Although it is able to land in 40-knot crosswinds, a minor accident happened when the rotor was not kept under control in a wind gust. A VPM M-16 commences its take-off roll Some autogyros, such as the Rotorsport MT03, MTO Sport (open tandem), & Calidus (enclosed tandem), and the Magni Gyro M16C (open tandem) & M24 (enclosed side by side) have type approval by the (CAA) under British Civil Airworthiness Requirements CAP643 Section T. Others operate under a permit to fly issued by the similar to the US experimental aircraft certification. However, the CAA's assertion that autogyros have a poor safety record means that a permit to fly will be granted only to existing types of autogyro. All new types of autogyro must be submitted for full type approval under CAP643 Section T. Beginning in 2014, the CAA allows gyro flight over congested areas.
In 2005, the CAA issued a mandatory permit directive (MPD) which restricted operations for single-seat autogyros, and were subsequently integrated into CAP643 Issue 3 published on 12 August 2005. The restrictions are concerned with the offset between the and thrust line, and apply to all aircraft unless evidence is presented to the CAA that the CG/Thrust Line offset is less than 2 inches (5 cm) in either direction. The restrictions are summarised as follows:. Aircraft with a cockpit/ may be operated only by pilots with more than 50 hours solo flight experience following the issue of their licence. Open-frame aircraft are restricted to a minimum speed of 30 mph (26 knots), except in the flare. All aircraft are restricted to a (maximum airspeed) of 70 mph (61 knots).
Flight is not permitted when surface winds exceed 17 mph (15 knots) or if the gust spread exceeds 12 mph (10 knots). Flight is not permitted in moderate, severe or extreme turbulence and airspeed must be reduced to 63 mph (55 knots) if turbulence is encountered mid-flight. These restrictions do not apply to autogyros with type approval under CAA CAP643 Section T, which are subject to the operating limits specified in the type approval. United States certification A certificated autogyro must meet mandated stability and control criteria; in the these are set forth in Part 27: Airworthiness Standards: Normal Category Rotorcraft. Issues a to qualified autogyros. Amateur-built or kit-built aircraft are operated under a in the Experimental category.
Per FAR 1.1, the FAA uses the term 'gyroplane' for all autogyros, regardless of the type of Airworthiness Certificate. World records In 1931, (USA) flew a to a women's world altitude record of 18,415 ft (5,613 m). (UK) held most of the autogyro world records during his autogyro flying career. These include a time-to-climb, a speed record of 189 km/h (111.7 mph), and the straight-line distance record of 869.23 km (540.11 mi). On 16 November 2002, at 89 years of age, Wallis increased the speed record to 207.7 km/h (129.1 mph) – and simultaneously set another world record as the oldest pilot to set a world record.
The autogyro is one of the last remaining types of aircraft which has not yet been used to circumnavigate the globe. Was the first attempt in history to the globe using an autogyro. The expedition set the record for the longest flight over water by an autogyro during the segment from, to. The attempt was finally abandoned because of bad weather after a trip totalling 7,500 miles (12,100 km). Little Wing Autogyro As of 2014, Andrew Keech (USA) holds several records. He made a transcontinental flight in his self-built 'Woodstock' from, to, in October 2003 and set three world records for speed over a recognized course. The three records were verified by tower personnel or by official observers of the United States' (NAA).
On 9 February 2006 he broke two of his world records and set a record for distance, ratified by the (FAI): Speed over a closed circuit of 500 km (311 mi) without payload: 168.29 km/h (104.57 mph), speed over a closed circuit of 1,000 km (621 mi) without payload: 165.07 km/h (102.57 mph), and distance over a closed circuit without landing: 1,019.09 km (633.23 mi). Autogyro Little Nellie with its creator and pilot, Ken Wallis An indication of the, its subsequent decline and later rise of interest can be inferred from its appearances in fiction of the day.
Appearances include:. In the film (1933), 's character flies around the globe in his autogyro The Spirit of Brooklyn. In the film (1934), the bridegroom King Westley arrives dramatically for the wedding, piloting the Kellett K-3 Autogiro NC12691.
A Weir autogyro briefly appears in 's movie (1935). 's first aircraft was an autogyro. The 'Batgyro' was introduced in #31 in September 1939. It only made three appearances before being replaced by a more conventional fixed-wing aircraft.
In the classic science fiction film of H.G. Wells' (1936), the heroes of the story arrive dramatically at the Space Gun in an -style autogyro (at 83m), to mitigate the destruction of the Space Gun by extremists. The autogyro in the film was designed by celebrated art deco designer, who assisted production designer on the look of the world of tomorrow. Fictional characters and featured autogyros in their 1930s and 1940s pulp magazine adventures, as did in his pulp styled comic. Little Nellie, the autogyro featured in the 1967 film, was a design and was piloted by Wallis in its film scenes.
In the film it was shipped by in four suitcases and assembled before use. A Wallis WA-116T two-seat autogyro is flown by the character Ben Driscoll in an episode of the 1979 USA NBC-TV television science-fiction miniseries. Driscoll flies the aircraft for 'fifteen hundred miles' just to meet Genevieve Seltzer, whom he believes to be the last woman on Mars. In the 1974 story, the Doctor uses a Campbell Cricket autogyro (G-AXVK) as part of a chase sequence. In 's 1979 anime film, Count Cagliostro utilizes an autogyro, notably against Lupin and company when they attempt to escape his castle residence with Clarisse in tow. An autogyro was heavily featured in the second film, released in 1981, appearing in several scenes with its pilot, the Gyro Captain, as a major character.
The pilot used in the flying sequences was Gerry Goodwin, doubling for the actor,. An autogyro appeared in the 1983 toyline and 80's cartoons as the Cobra (Fully Armed Negator Gyrocopter). After Pippi Longstocking sees an autogyro in flight, she and her friends build their own in the 1988 movie. In the 1991 film, the hero Cliff Secord and his girlfriend Jenny are rescued from an exploding zeppelin at the last second by an autogyro piloted by their friend Peevy and a fictional.

A gyrocopter is an easy-to-fly aircraft that’s remarkably maneuverable. Unlike a helicopter, a gyrocopter doesn’t need a tail rotor, which enables you to fly one with a joystick. Although flying a gyrocopter can take a while to master, building one is not so difficult. Below is a short guide that will assist you in building your own gyrocopter.
Step 1 – Choose the Design First, you need to determine the design that you want to use for your gyrocopter because the frame will depend on it. There are designs that are meant to work efficiently, and there are also designs that are made with ease of construction in mind.
You might want to check with a few gyrocopter enthusiasts and pilots to get an idea of the pros and cons of various designs. Step 2 – Purchase Panel Material Once you have the design picked out, you will be able to identify the exact length and the sizes of squared aluminum or galvanized steel sheets and the number of bolts and screws that you will need. Most plans for do-it-yourself gyrocopters include this information, so it should not be difficult to determine. You can even purchase gyrocopter kits, which already contain all the parts for easy assembly. If you don't purchase a kit, you will need to visit a machine shop and have the metal cut to exact measurements.
Step 2 – Planning, Measuring, and Drilling Holes When your squared aluminum, or, is ready, you can now start to drill. Use a sharp hand drill and flat-steel drilling guides to ensure more accurate depth cuts.
Refer to the Manual The distance between holes should be exact and follow instruction manual guidelines precisely. While you are drilling, continue to refer to the manual often to ensure your measurements are precise when creating the gyrocopter frame. Ensure Straightness Also, make sure the drill holes are completely straight and level, using a chalk line and a level. You should spend more time measuring and marking the drill holes than you should drilling them. Step 3 – Assembling Square Aluminum or Galvanized Steels Connect all the square aluminum properly with screws and bolts.
Use Safety Wire To keep the bolts from jumping out of the hole, you can use safety wire. This wire will provide additional protection by serving as backup support, and it also helps to strengthen your gyrocopter frame. Airframe vibration naturally occurs after the copter is in the air, and this vibration can loosen screws and bolts. However, with safety wire attached to the bolts, you can minimize this risk. Once you've finished building the frame, you can begin constructing the rest of your gyrocopter and.
