Aériane Swift
The Aériane Swift is a lightweight (48 kg) foot-launched tailless sailplane whose rigid wings have a span of 40 feet. The Swift has been succeeded by the "Swift'Lite". Although designed in California, Swift aircraft are now manufactured by Aériane, a European firm based in Gembloux, Belgium. Aériane first manufactured the Swift under licence, but the firm is now the sole manufacturer. Design & development The Swift (an acronym for 'Swept Wing with Inboard Flap for Trim') was originally conceived as a rigid hang glider with sailplane-like performance. Bright Star Gliders had developed the 1989 U.S. National Hang Gliding Championship winning Odyssey prototype. Meanwhile Professor Ilan Kroo and a group of graduate students at Stanford University had developed the Stanford SWIFT design project. When Brian Porter of Bright Star met Stanford student Steve Morris, the projects merged. Bright Star constructed the revised SWIFT and its first flight took place in December 1989.Il ...

Tailless Aircraft
In aeronautics, a tailless aircraft is an aircraft with no other horizontal aerodynamic surface besides its main wing. It may still have a fuselage, vertical tail fin (vertical stabilizer), and/or vertical rudder. Theoretical advantages of the tailless configuration include low parasitic drag as on the Horten H.IV soaring glider and good stealth characteristics as on the Northrop B-2 Spirit bomber. Disadvantages include a potential sensitivity to trim. Tailless aircraft have been flown since the pioneer days; the first stable aeroplane to fly was the tailless Dunne D.5, in 1910. The most successful tailless configuration has been the tailless delta, especially for combat aircraft, though the most familiar tailless delta is the Concorde airliner. NASA has used the 'tailless' description for the novel X-36 research aircraft which has a canard foreplane but no vertical fin. Aircraft configuration A tailless aircraft has no other horizontal surface besides its main wing. The aer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hang Gliders
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to soar for hours, gain thousands of feet of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the safety benefits of being instructed is highly recommended and indeed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rensselaer RP-1
The Rensselaer RP-1 (for Rensselaer Polytechnic design 1) is an American low-wing, single-seat, foot-launchable glider that was designed and produced by the Rensselaer Polytechnic Institute of Troy, New York. It first flew in 1980. Design and development The RP-1 was partly funded by NASA and was the first aircraft in Rensselaer's Composite Aircraft Program. The aircraft is of mixed construction, made from composites, Kevlar and PVC foam. Its span wing employs a Wortmann FX-63-137 airfoil. The aircraft weighs just and was intended to be foot-launched. The landing gear consists of a main skid and dual tail skids. The aircraft achieved a 20:1 glide ratio In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under giv .... Only one was completed. Specifications (RP-1) See also Referenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitchell U-2 Superwing
The Mitchell U-2 Superwing is an American tailless ultralight aircraft that was designed by Don Mitchell for amateur construction.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page E-259. Cybair Limited Publishing, 2001. Design and development Although the aircraft was designed before the US FAR 103 Ultralight Vehicles rules came into force, the U-2 Superwing complies with them anyway (including the category's maximum empty weight of ). The aircraft has a standard empty weight of . It features a cantilever mid-wing, a single-seat enclosed cockpit, tricycle landing gear and a single engine in pusher configuration. The U-2 is a development of the high-wing B-10. The aircraft fuselage is made from welded steel tube, while the wing is of wood and foam, with doped aircraft fabric covering. Its span wing employs a modified Wortmann FX05-191 airfoil. The flight controls are unconventional; pitch and roll are controlled by elevons and yaw is controlled by ...

Maupin Carbon Dragon
The Maupin Carbon Dragon is an American, high-wing, single-seat, glider that was designed by Jim Maupin and made available as plans for amateur construction. Plans are no longer available.Maupin, Jim: ''Carbon Dragon'', sales brochure, October 1988Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003–04'', p. 57. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X Design and development The Carbon Dragon was intended to take advantage of the US FAR 103 Ultralight Vehicles regulations that classify unpowered aircraft with empty weights of or less as hang gliders and thus allow them to be flown without a pilot license, Federal Aviation Administration aircraft registration or a Certificate of Airworthiness. The Carbon Dragon's standard empty weight is and the aircraft has a gross weight of , giving a payload of . The designer said "The philosophy behind its development was to try to bring foot launch soaring performance up into the lower performance ran ...

Hall Vector 1
The Hall Vector 1 is an American high-wing, ultralight glider that was designed by Stan Hall for serious cross-country flights.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 44. Soaring Society of America, November 1983. USPS 499-920 Design and development The Vector 1 was intended to take advantage of the US informal rules for hang gliders at the time of its development that in 1982 became the FAR 103 Ultralight Vehicles regulations. These define a hang glider as any unpowered glider with an empty weight of or less. The Vector 1 was designed with the goal of building a foot-launchable glider with cross country performance. With an empty weight of , the design qualifies as a hang glider and thus does not need to be registered or have a Certificate of Airworthiness. The aircraft resembles a small sailplane and not a traditional hang glider. The aircraft achieves its light weight through small dimensions, with a wingspan of only . The Vector 1 was designed ...

Folding Propeller
A folding propeller is a type of propeller whose blades automatically fold out when the engine is turning, and then fold back (or "feather") when the engine stops. Folding propellers are found on sailing yachts, on model airplanes, and increasingly on self-launching gliders and small motor gliders, such as the Aériane Swift PAS. Their purpose of folding propellers is to reduce drag when sailing or soaring, respectively. Folding propellers are spun outwards by centrifugal force In Newtonian mechanics, the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parall ... when the engine is turning, but when the engine stops, the pressure of airflow or waterflow forces the blades back. Typically, the blades are geared together so that they open and close in unison. Folding propellers used mainly to be two-bladed, but 3-bl ...
