Rans S-11 Pursuit
The Rans S-11 Pursuit is an American single-engined, tractor configuration, single-seat, low-wing aircraft, based on the lifting body principle, designed and built by Randy Schlitter. The Pursuit was listed as ''under development'' in 1998, but only prototypes were ever completed and the aircraft is not part of the present Rans aircraft line.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 356. BAI Communications, July 1998. Design and development The S-11 was conceived as a unique single seat sport aircraft, based on the lifting body concept pioneered by NASA in the 1960s. The aircraft design derives 80% of its lift from the aircraft fuselage and associated strakes and only 20% from its straight wings. The Pursuit is a straked, low wing single or dual seat aircraft with tricycle landing gear and dual rudders. It is made from a welded steel fuselage with aluminum ribs and a composite shell. The prototype's engine was a Rotax 912UL of , with the Rotax 582 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration.

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has three regional offices, located in Anchorage, Alaska; Aurora, Colorado; and Federal Way, Washington. The agency also operated a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the time the CAA/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

Lifting Bodies
A lifting body is a fixed-wing aircraft A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor mounted on a spinning shaft generate ... or spacecraft configuration in which the body itself produces lift (force), lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing. Whereas a flying wing seeks to maximize cruise efficiency at Subsonic flight, subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic and hypersonic flight, or spacecraft re-entry. All of these flight regimes pose challenges for proper flight safety. Lifting bodies were a major area of research in the 1960s and 1970s as a means to build a small and lightwe ...

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 aircraft, Experimental under Federal Aviation Administration, 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 m ...

Glasair I
The Glasair I, originally built as the prototype Glasair TD taildragger, is a high-performance homebuilt aircraft built of fiberglass. Created by Tom Hamilton as a fast, two-seat kitplane, the Glasair TD was derived from the earlier Tom Hamilton Glasair and first flew in 1979. Hamilton formed Stoddard-Hamilton Aircraft that year to produce and market the kit, which was the first pre-molded composite aircraft available to builders. It was introduced to the public at the 1980 EAA Convention in Oshkosh, Wisconsin, winning Hamilton the 1985 EAA August Raspet Award for "significant advancements in the field of light aircraft A light aircraft is an aircraft that has a Maximum Takeoff Weight, maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308.

Northrop HL-10
The Northrop HL-10 is one of five US heavyweight lifting body designs flown at NASA's Flight Research Center (FRC—later Dryden Flight Research Center) in Edwards, California, from July 1966 to November 1975 to study and validate the concept of safely maneuvering and landing a low lift-over-drag vehicle designed for reentry from space. It was a NASA design and was built to evaluate "inverted airfoil" lifting body and delta planform. It currently is on display at the entrance to the Armstrong Flight Research Center at Edwards Air Force Base. Development Northrop Corporation built the HL-10 and Northrop M2-F2, the first two of the fleet of "heavy" lifting bodies flown by the NASA Flight Research Center. The contract for construction of the HL-10 and the M2-F2 was $1.8 million.

Experimental Aircraft Association
The Experimental Aircraft Association (EAA) is an international organization of aviation enthusiasts based in Oshkosh, Wisconsin. Since its inception, it has grown internationally with over 300,000 members and nearly 1,000 chapters worldwide. It hosts the largest aviation gathering of its kind in the world, EAA AirVenture Oshkosh. History The EAA was founded in 1953 by veteran aviator Paul Poberezny along with other aviation enthusiasts. The organization began as more or less a flying club. Poberezny explains the nature of the organization's name, "Because the planes we flew were modified or built from scratch, they were required to display an EXPERIMENTAL placard where it could be seen on the door or cockpit, so it was quite natural that we call ourselves the "Experimental Aircraft Association". The EAA was incorporated in Wisconsin on 22 March 1955. Homebuilt aircraft, Homebuilding is still a large part of EAA, but the organization has grown over the years to include almost ...
