Sud-Est. Опытные военные самолеты
Последним в серии интереснейших прототипов истребителей Sud-Est был одноместный S.E.212 Durandal. Прототип легкого перехватчика с треугольным крылом выполнил первый полет 20 апреля
1956 года, его испытания завершились в 1957 году.
На Durandal IV стоял более мощный двигатель Atar. Работы по самолету свернули после объединения 1 марта 1957 года компаний "Sud-Est" (SNCASE) и "Sud-Ouest" (SNCASO), в результате чего образовался концерн "Sud-Aviation".
Силовая установка самолета SE-212 Durandal состояла из ТРД SNECMA Atar G-3 тягой 44,13кН и ЖРД SEPR.65 тягой 825 кг.
The SNCASE Durandal delta fighter has been under development for the past two years and two airframes are now well advanced at Toulouse. It is a "light fighter" in the sense that it is smaller than the Hunter and Sabre, being more of the Venom size - or the F-104. It has absolutely no connection with the NATO light attack fighters, having been designed to an earlier and quite different specification.
SUD-EST SE-212 DURANDAL. The timely perfection of the small-diameter and limited weight-for-power British and French turbojets has permitted the rapid development of lightweight ground-attack and interceptor single-seaters. The grandfather clock giants typified by the 42,000-lb. a.u.w. strategic-escort McDonnell F-101A Voodoo can now be matched in altitude performance by such lightweights as the (roughly) 8,000-lb. a.u.w. Folland Fo.141 Gnat and the 9,000-lb. a.u.w. Sud-Est Aviation SE-212 Durandal. But whereas the U.S.A.F. has to cope with global attack/defence measures call ing for heavyweight colossi, Europe faces immediate (potential) attack from airfields rarely more than 400-500 miles from the capitals and industrial areas.
Thus, over the past two years there has sprung up a crop of European lightweights - in the main, Italian and French. In this respect the December 1953 N.A.T.O. specification call ing for a ground-attack fighter spurred effort. The competition has been won by the Fiat G-91, with second and third "places" going to the French Breguet Br. 1001 Taon and Dassault Etendard (Pennant) VI .
Parallel to this ground-attack effort has been the strides taken in producing turbojet and mixed-powerplant target-defence interceptors. Among the most promising are the Sud-Ouest SO-9050 Trident II and its close rival, the Durandal. Both are designed to achieve Mach 1.5 "plus" above 36,000 ft. in level flight and to intercept above 55,000 ft., where the rocket motor is in its element.
The small size of the SE-212 means limited fuel storage and suggests a combat radius of not more than two hundred miles and combat interception of not more than five minutes from a standing start. For this reason the SE-212 will carry a "one-shot" heavy calibre guided missile, pylon-mounted under the fuselage.
The SE-212 is a true delta of 60 degrees, with an area of 236 sq. ft. and a thickness/chord ratio not exceeding 5 per cent. To assist control at critical speeds the SE-212 possesses a unique strake under the nose, which also forms part of the nosewheel doors. To reduce speed at altitude the Durandal is equipped with air brakes, four "petal" doors situated behind the wing trailing edge.
There are two SE-212s, the first (SE-212-01) was flown for the first time by Sud-Est's C.T.P. Pierre "Tito" Maulandi on 20th April 1956 at C.E.V. Istres, west of Marseilles. In place of the current 8,370-lb. s.t. SNECMA Atar 101 F-2, the SE-212-01 will have the 9,700 lb. s.t. Atar 101 G-21 - both thrusts being quoted with SNECMA (two-door) reheat applied.
