The Nord Gerfaut (en:Gyrfalcon) was a delta-wing experimental research aircraft, originally designed and built by SFECMAS - ''Société Française d'Etude et de Construction de Matériel Aéronautiques Spéciaux '' which was later merged with SNCAN - ''Société Nationale de Constructions Aéronautiques du Nord '' to form Nord Aviation. ==Development== The Nord 1402 Gerfaut series had their origin in a state sponsored study into delta and swept wings. To provide data for these studies Arsenal de l'Aéronautique (SFECMAS's nationalised predecessor) designed and built two supersonic gliders; the Arsenal 1301 and Arsenal 2301 with delta and swept surfaces respectively. Towed to the release point by SNCAC Martinet, Douglas DC-3 or SNCASE Languedoc transport aircraft, these gliders provided valuable data for the design of the Gerfaut.〔 To utilise this data SFECMAS engineers instigated the 1400,1500 and 1910 interceptor projects with delta wings and different propulsion systems. The 1400 developed into the Gerfaut series,the 1500 became the Nord Griffon and the 1910, with two large ramjet engines remained stillborn.〔 Different versions of the Arsenal / SFECMAS 1400 were studied as the:- * Arsenal 1401 powered by a combined ramjet / turbojet powerplant and high set wings.〔 * Arsenal 1402 powered by a ramjet with auxiliary Turboméca turbojet, and middle set wings.〔 * Arsenal 1403 powered by a combined ramjet / turbojet powerplant and middle set wings.〔 * Arsenal 1404 powered by a combined ramjet / turbojet powerplant and low set wings.〔 * Arsenal 1405 powered by an ATAR 101 turbojet powerplant and low set wings.〔 By the time that construction of prototypes started the interceptor requirement had overtaken the Gerfaut so the aircraft was designed as a research aircraft. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nord Gerfaut」の詳細全文を読む スポンサード リンク
