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<h3><span id=\"Supersonic_deltas\" class=\"mw-headline\">Supersonic deltas<\/span><\/h3>\n<p>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&#8217;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 id=\"cite_ref-11\" class=\"reference\"><\/sup><\/p>\n<p>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<p>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 (&#8220;Fishbed&#8221;) and Sukhoi Su-9\/Su-11\/15 fighters, built by the tens of thousands in several different communist countries<\/p>\n<p>(photos: Lippisch DM1 &#8211;\u00a0by\u00a0Matthias Oberhauser\u00a0|\u00a0Delta Dart &#8211; by Nasa | Concorde &#8211;\u00a0Eduard Marmet)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Early deltas Triangular stabilizing fins for rockets were described ca. 1529-1556 by Conrad Haas and in the 17th century by Kazimierz Siemienowicz.
