XFV-1
The Lockheed XFV (sometimes referred to as the "Salmon") was an American experimental tailsitter prototype aircraft built by Lockheed in the early 1950s to demonstrate the operation of a vertical takeoff and landing (VTOL) fighter for protecting convoys. Design and development The Lockheed XFV originated as a result of a proposal issued by the U.S. Navy in 1948 for an aircraft capable of vertical takeoff and landing (VTOL) aboard platforms mounted on the afterdecks of conventional ships. Both Convair and Lockheed competed for the contract but in 1950, the requirement was revised, with a call for a research aircraft capable of eventually evolving into a VTOL ship-based convoy escort fighter. On 19 April 1951, two prototypes were ordered from Lockheed under the designation XFO-1 (company designation was Model 081-40-01). Soon after the contract was awarded, the project designation changed to XFV-1 when the Navy's code for Lockheed was changed from O to V.Allen 2007. p. 14. The ...

Tailsitter
A tail-sitter, or tailsitter, is a type of VTOL aircraft that takes off and lands on its tail, then tilts horizontally for forward flight. Originating in the 1920s with the inventor Nikola Tesla, the first aircraft to adopt a tail-sitter configuration were developed by Nazi Germany during the Second World War. Development of such aircraft spiked during the late 1940s and 1950s, as aircraft designers and defence planners alike recognised the potential value of fixed-wing aircraft that could perform both a vertical take-off and vertical landing while also transitioning into and out of conventional flight. Inherent problems with tail-sitter aircraft were poor pilot visibility and control difficulties, especially during vertical descent and landing. Programmes to develop manned tail-sitters were typically terminated in the form of the more practical thrust vectoring approach, as used by aircraft such as the Hawker Siddeley Harrier and Yakovlev Yak-38.

Herman "Fish" Salmon
Herman Richard Salmon (July 11, 1913 – June 22, 1980), nicknamed "Fish", was a barnstormer, air racer, and test pilot for the Lockheed Corporation. Biography Early life Salmon was born in 1913 in Milwaukee, Wisconsin, to Pennsylvania-born engineer Harry Britton Salmon and his wife Bertha Wilhelmine ''née'' Wagner.United States Census Bureau, National Archives and Records Administration His first flight in an aircraft was at the age of 14; by 18 he was a licensed pilot. During the 1930s he flew as a barnstormer, parachute stuntman and race pilot. By 1940 he was living in Los Angeles, California with his first wife Evelyn. Lockheed He started work at Lockheed in 1940 ferrying Hudsons to Montreal for the Royal Air Force. In 1945, he was transferred to the engineering test piloting division by Tony LeVier, who was the new head of the department. As engineering test pilot, he spin tested the P-38 Lightning and dive tested the P-80 Shooting Star, the XF-90 penetration fig ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Heinkel Lerche
The Heinkel Lerche ( en, Lark) was the name of a set of project studies made by German aircraft designer Heinkel in 1944 and 1945 for a revolutionary VTOL fighter and ground-attack aircraft. The ''Lerche'' was an early coleopter design. It would take off and land sitting on its tail, flying horizontally like a conventional aircraft. The pilot would lie prone in the nose. Most remarkably, it would be powered by two contra-rotating propellers which were contained in a doughnut-shaped, nine-sided annular wing. The remarkably futuristic design was developed starting 1944 and concluding in March 1945. The aerodynamic principles of an annular wing were basically sound, but the proposal was faced with a whole host of unsolved manufacture and control problems which would have made the project highly impractical, even without the material shortages of late-war Nazi Germany. Specifications (''Lerche'' II) :Figures below are given for the 'Lerche II' plan dated 25 Feb 1945. See also R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focke-Wulf Triebflügel
The Focke-Wulf ''Triebflügel'', or ''Triebflügeljäger'', literally meaning "thrust-wing hunter", was a German concept for an aircraft designed in 1944, during the final phase of World War II as a defence against the ever-increasing Allied bombing raids on central Germany. It was a vertical take-off and landing tailsitter interceptor design for local defense of important factories or areas which had small or no airfields. The ''Triebflügel'' had only reached wind-tunnel testing when the Allied forces reached the production facilities. No complete prototype was ever built. Design The design was particularly unusual. It had no wings, and all lift and thrust were provided by a rotor/propeller assembly 1/3 of the way down the side of the craft (roughly halfway between the cockpit and tailplane). When the plane was sitting on its tail in the vertical position, the rotors would have functioned similarly to a helicopter. When flying horizontally, they would function more li ...
