Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Rocket Racing League
The Rocket Racing League was a racing league that planned to use rocket-powered aircraft to race a closed-circuit air racetrack. Founded in 2005, the league made its first public flights in 2010 and was working to begin regular racing seasons. The "Rocket Racers" were slated to compete in the air and on a virtual racetrack easily viewed by a live audience as well as projected on large screen and handheld electronic displays. Three prototype canard-style ''Rocket Racer'' aircraft were built between 2006 and 2010. The league had planned to hold its inaugural race season in 2008 with four races, but encountered financial difficulties that delayed fielding of ''Rocket Racers'' by the six teams that had been previously announced. With the addition of venture capital funding in mid-2009, technology development continued and one exhibition occurred in 2010, with another round of plans for an inaugural season of races in 2011. The 2011 races were, in the end, never scheduled, and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raptor Aircraft Raptor
The Raptor was a four to five-seat single-engined canard-wing homebuilt light aircraft, whose prototype was under development by Raptor Aircraft of Ball Ground, Georgia, United States. The Raptor's tricycle landing gear was fully retractable, and the streamlined pressurized airframe was to be optimized for a fast cruising speed at high altitudes. The aircraft was intended to be supplied in kit form for amateur construction. The aircraft's designer is Australian Peter Muller, whose design goals were to provide a fast, spacious aircraft with IFR capability. Muller intended that the kit would be sold "at cost". The prototype made its first substantive flight on 10 October 2020. During a ferry flight on 6 August 2021 the Raptor prototype crashed in a cornfield, suffering substantial damage. Subsequently, Muller announced that development of the Raptor would end and the company would move onto developing a derivative design, the Raptor Aircraft Raptor NG. Design and develo ...

Cozy MK IV
The Cozy Mark IV is a 4-seat, single engine, homebuilt light aircraft designed by Nat Puffer, with parts and plans supplied by Aircraft Spruce & Specialty Co. The aircraft is built from plans using basic raw materials. It is not a kit aircraft, though many small parts are available prefabricated. The Cozy is similar in design and construction to the 2-seat Rutan Long-EZ, from which it is derived,Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 98. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X with approval from Burt Rutan. The Cozy Mark IV utilizes foam and fiberglass sandwich construction, with foam suited to the usage, fiberglass oriented for the stresses, and epoxy to bond them together. Nat Puffer designed the aircraft as a high speed cross-country visual flight rules (VFR) aircraft, although many builders equip their planes with instrument flight rules (IFR) capabilities.Zeitlin, Marc J.: ''See partial list of completed builds on t ...

Berkut Aircraft
The Berkut 360 is a tandem-seating, two-seat homebuilt canard aircraft with pusher configuration and retractable landing gear, built primarily of carbon fiber and fiberglass. The Berkut 360 is featured in the 2010 movie ''Kill Speed'' (''Fast Glass''). Development The prototype Berkut was designed and built by Dave H. Ronneberg as part of a business partnership between Ronneberg and Donald S. Murphy, called Experimental Aviation, that lasted from 1989 to 1992. In 1992 the partnership dissolved and Ronneberg, incorporating as Experimental Aviation, Inc., brought the aircraft to market as a kit, while Murphy wanted to shelve the project entirely. A subsequent series of lawsuits between the two resulted in bankruptcy for Ronneberg and Murphy as individuals and for Experimental Aviation as a corporation. The kit was resurrected in 1996 by Richard Riley and Renaissance Composites, with Ronneberg working as a consultant. In January 2001, under pressure from Ronneberg, Renaissance ...

Rutan Defiant
The Rutan Model 40 Defiant is a four-seat, twin-engine homebuilt aircraft with the engines in a push-pull configuration. It was designed by aerospace engineer Burt Rutan for the Rutan Aircraft Factory. ] Development The prototype Defiant, N78RA, was first flown on 30 June 1978. It had been intended as a proof-of-concept of a very safe light twin design, requiring little trim change and no pilot action in case of engine failure, and with good single engine performance. A comparison of the Defiant single engine climb rate with a Gulfstream American GA-7 Cougar, Gulfstream Cougar had shown about vs per minute at low altitude with both aircraft cleaned up. The prototype is now owned by the Hiller Aviation Museum. In 1979 the Rutan Aircraft Factory announced they would proceed with certification of a Defiant-based light twin. Adequate financing was not secured for this project, and the design was modified for homebuilt construction as the Model 74, with the second aircraft (b ...

Rutan VariEze
The Rutan VariEze is a composite, canard aircraft designed by Burt Rutan. It is a high-performance homebuilt aircraft, hundreds of which have been constructed. The design later evolved into the Long-EZ and other, larger cabin canard aircraft. The VariEze is notable for popularizing the canard configuration and moldless glass cloth composite construction for homebuilt aircraft. Overview Work on the VariEze design, which grew out of Rutan's experience designing and building the VariViggen, began in 1974. The first prototype, designated Model 31 and registered N7EZ, first flew on May 21, 1975 after four months of construction. This aircraft used a Volkswagen engine conversion. Three months later it was shown at Oshkosh where Dick Rutan piloted it to an under 500 kg class distance record of . Rutan believed that by engaging in a program of breaking class records he could further fine-tune the design. The aircraft was so popular at Oshkosh that Rutan redesigned the airc ...

Rutan Long-EZ
The Rutan Model 61 Long-EZ is a tandem 2-seater homebuilt aircraft designed by Burt Rutan's Rutan Aircraft Factory. The Long-EZ has a canard layout, a swept wing with wingtip rudders, and a pusher engine and propeller. The tricycle landing gear has fixed main wheels with streamlined spats and a retractable nosewheel. Its predecessor was the VariEze, plans for which were first available to homebuilders in 1976. The prototype Long-EZ, N79RA, first flew on June 12, 1979. Design The Long-EZ was a scaled-up redesign of the VariEze predecessor, allowing for the use of readily available Lycoming aircraft engines instead of the Volkswagen-derived engines or hard-to-find small Continentals for which the VariEze was designed. Changes from the VariEze included a larger main wing with modified Eppler 1230 airfoil and less sweep, larger strakes containing more fuel and baggage storage, and a slightly wider cabin. The canard uses the same GU25-5(11)8 airfoil as the VariEze. Plans were o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freedom Aviation Phoenix
The Freedom Aviation Phoenix was a single-engine four-seat American airplane that was sold as a homebuilt composite canard aircraft. The kit was produced at a facility on St. Lucie County International Airport at Ft. Pierce, Florida. Design and development The Phoenix airframe was formed of carbon-fiber composite materials on factory molds. The aircraft was assembled as a homebuilt, with a factory-sponsored builder-assist program available. The aircraft has a swept, dihedral canard mounted ahead of the cabin, and a swept main lifting surface. Each wing has a fin (with full-length rudder) mounted about midway to the tip. In addition, the wingtips have swept winglets, which provide additional yaw stability while decreasing induced drag. The Phoenix is powered by a six-cylinder horizontally-opposed piston engine driving a pusher propeller. The tricycle landing gear is retractable. Only one aircraft was ever built, and the company has since gone out of business. Specifications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 ''Wilson-Pilcher 18/24 HP'' car. The most notable use of flat-six engines is the Porsche 911 sports car, which has used flat-six engines continuously since 1963. Several o ...

Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the e ...
