苏恺设计局(Sukhoy)

正式名称OKB imeni P.O. Sukhoy

旧称OKB-51

俄罗斯航太设计局，是该国第二大的喷射战斗机制造商（仅次於米格设计局）。苏恺设计局起源於1953年，苏联政府允许苏恺重组他在第二次世界大战领导的飞机设计团队成为设计局，命名为OKB-51。在1950与1960年代，OKB-51计画并建造一系列的超音速喷射战斗机，包括Su-7及Su-9，後来经过修改，广泛为苏联及其他华沙公约国家采用。将Su-9改良推出Su-11及Su-15战斗拦截机。在苏恺去世（1975）之後，设计局冠上他的姓。苏恺设计局最着名的作品可能是多功能空优战斗机Su-27（1977年第一次飞行）。在1990年代设计局推出Su-37战斗轰炸机及重新设计的Su-39地面攻击机。第五代战机多任务空优战斗机S-37金雕（1997），有最先进的电子设备、前掠翼，推进动力控制。1997年俄罗斯结合设计局与生产工厂等相关公司成立部分国有的苏恺公司。在21世纪开始多样化，进入民用市场，生产运动飞机、货机与客机。

Sukhoy

formerlyOKB-51Russian aerospace design bureau that is the country's second most important producer of jet fighters (after MiG). The origin of Sukhoy dates to 1953, when the Soviet government allowed Pavel Sukhoy to reassemble his World War II aircraft-design team into a new bureau, which was designated OKB-51. In the 1950s and '60s OKB-51 planned and built a series of supersonic jet fighters, including the Su-7 and Su-9, which were later modified and used extensively by the U.S.S.R. and other Warsaw Pact countries. It improved the Su-9 into the Su-11 and Su-15 fighter-interceptors. After Sukhoy's death (1975) his name was added to that of the bureau. Perhaps the best known Sukhoy design was the versatile Su-27 air-superiority fighter (first flown 1977). In the 1990s the bureau introduced the Su-34 fighter-bomber and the redesigned Su-39 ground-attack aircraft. Its fifth-generation multirole S-37 Berkut air-superiority fighter (1997), had state-of-the-art electronics, forward-swept wings, and thrust vector control. In 1997 Russia formed the partially state-owned AVPK Sukhoy by combining the design bureau with its production plant and other affiliates. At the start of the 21st century Sukhoy began diversifying into the civilian market with sports aircraft, freight vehicles, and passenger aircraft.
