A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ).
Alexander Martin Lippisch was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect, and also worked in the U.S. Within the Opel-RAK program, he was the designer of the world's first rocket-powered glider.
Alexander Lippisch's Delta IV was a continuation of his work on delta wing designs pioneered in his Delta I, Delta II and Delta III aircraft.
In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of air- or watercraft with its propulsion device(s) after its engine(s). This is in contrast to the more conventional tractor configuration, which places them in front.
The Convair XF-92 was an American, delta wing, first-generation jet prototype. Originally conceived as a point-defence interceptor, the design was later used purely for experimental purposes and only one was built. However, it led Convair to use the delta-wing on a number of designs, including the F-102 Delta Dagger, F-106 Delta Dart, B-58 Hustler, the US Navy's F2Y Sea Dart as well as the VTOL FY Pogo.
Wunderwaffe is a German word meaning "wonder-weapon" and was a term assigned during World War II by Nazi Germany's propaganda ministry to some revolutionary "superweapons". Most of these weapons however remained prototypes, which either never reached the combat theater, or if they did, were too late or in too insignificant numbers to have a military effect. The V-weapons, which were developed earlier and saw considerable deployment, especially against London and Antwerp, trace back to the same pool of highly inventive armament concepts. In the German language, the term Wunderwaffe generally refers to a universal solution which solves all problems related to a particular issue, mostly used ironically for its illusionary nature.
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, and/or vertical rudder.
The Pobjoy R is a British seven-cylinder air-cooled radial aircraft engine designed and built by Pobjoy Airmotors. Introduced in 1926, it was a popular engine for ultralight and small aircraft in the 1930s. A notable feature of the Pobjoy R was the propeller reduction gear which allowed the small engine to operate at more desirable higher speeds.
The DFS 193 was a planned experimental German aircraft of the 1930s planned by Deutsche Forschungsanstalt für Segelflug (DFS). Designed by Professor Alexander Lippisch and a DFS employee named Roth, it resembled Lippisch's Storch IX and the Gotha Go 147.
The Teichfuss Cicogna was an Italian tailless single-seat motor glider designed by Luigi Teichfuss and flown in 1936.
The RRG Falke of 1930 was a secondary training glider designed by Alexander Lippisch in Germany and intended to provide better performance than his earlier RRG Prüfling whilst being easier to fly because of its inherent stability. It was sold as plans for both club and commercial production and was built in Germany and abroad.
The Fieseler F 4 was developed, built and flown as a two-seat sports and travel aircraft at the Fieseler Flugzeugbau.
The RRG Storch V was the only member of Alexander Lippisch's Storch series of tailless aircraft to be powered. It flew successfully in the year 1929.
The RRG Delta I was a German experimental tailless aircraft flown in the early 1930s first as a glider and then powered. It was one of the first delta wing aircraft.
The Lippisch Delta VI was a proposed single-seat, twin-jet experimental delta flying wing aircraft begun in 1943 by German designer Alexander Lippisch, as the developed version of the P.11 bomber project begun while he was still working for Messerschmitt in 1942. The only prototype was destroyed in June 1944 while still under construction.
