Early deltas<\/span><\/h3>\n

Triangular stabilizing fins for rockets were described ca. 1529-1556 by Conrad Haas and in the 17th century by Kazimierz Siemienowicz.<\/sup><\/p>\n

The lifting delta wing was pioneered by Alexander Lippisch in Germany after WWI, initially using a very gentle angle so that the wing appeared almost straight. He flew the first tailless delta aircraft in 1931, followed by four improved designs.\u00a0<\/span>None of these designs were easy to handle at low speed and none saw widespread service.<\/p>\n

During WWII Lippisch studied a more advanced tailless delta wing of greater angle intended for high-speed and even supersonic flight, for use in interceptor aircraft. One progressed as far as a glider prototype.<\/p>\n

The British later developed jet aircraft based on the data from Lippisch, notably the Avro Vulcan strategic bomber and the Gloster Javelin fighter. The Javelin incorporated a tailplane in order to rectify some of the perceived weaknesses of the pure delta, to improve low-speed handling and high-speed manoeuvrability and to allow a greater center of gravity range.<\/p>\n

Supersonic deltas<\/span><\/h3>\n

In America Robert T. Jones, working at NACA during World War II, developed a theory for supersonic delta wings. First published in January 1945, this approach differed from Lippisch’s earlier work on thick delta wings by combining a delta planform with a thin airfoil. This design proved to be superior and would form the basis of all practical supersonic deltas such as those first made by Convair.<\/sup><\/p>\n

The tailless delta became a favored design for high-speed aircraft, and was used almost to the exclusion of other designs byConvair and by Dassault Aviation, notably with the Dassault Mirage III. The F-102 Delta Dagger and Douglas F4D Skyray\u00a0were two of the first operational jet fighters with a tailless delta wing when they entered service in 1956.<\/p>\n

The tailed delta configuration was again adopted by the TsAGI (Central Aero and Hydrodynamic Institute, Moscow), to take advantage of both high angle-of-attack flying capability and high speeds. It was used in the MiG-21 (“Fishbed”) and Sukhoi Su-9\/Su-11\/15 fighters, built by the tens of thousands in several different communist countries<\/p>\n
