二战之后,冷战的阴云开始笼罩全球。美.苏两个超级大国都为保卫自己的领空而研制高性能的截击机.苏联决定在图波列夫飞机设计局设计的世界上最大的截击机图-128P“小提琴家”的基础上尝试研制一种满足远距离截击和续航时间更长的截击机.并尝试可以用飞机自身的远程截击雷达来增大飞机的早期预警功能。 1968年苏联政府要求设计一种性能更好的远程截击机并要具备独自在苏联北部地区巡逻的能力。在对图波列夫飞机设计局、雅克夫列夫设计局和米高扬设计局设计的飞机进行评估之后,苏联国防部最后决定在米高扬设计局的米格-25MP的基础上发展一种全天候截击机.以满足需求。1976年9月6日,维克多·别连科上尉驾驶他的米格-25“狐蝠”A战斗机叛逃到达日本北海道的函馆机场。可能是作为一种迷惑手段,苏联的工厂将新型“狐蝠”的文件编号定为83.而早期的型号定为84,米高扬设计局将其原型机的名字由米格-25MP改为Ye-155MP.其主要原因与别连科叛逃有关.事实上Ye-155MP要比米格-25MP包含更多的设计理念.包括可变几何型机翼。从表面上看,Ye-155MP与米格-25相似.但是Ye-155MP逐渐发展成米格-31后.其气动力外形得到改进,在结构上,新式武器配置和航空电子设备等方面上都得到非常大的改进。
After World War II, the dark clouds of the cold war began to shrouded the world. Both the United States and the Soviet Union have developed high-performance interceptor aircraft to defend their own airspace. The Soviet Union decided on the basis of the world's largest interceptor figure Tu-128P “violinist” designed by the Tupolev Aircraft Design Bureau Try to develop an interceptor that meets longer range interception and longer battery life and try to increase the early warning function of the aircraft with its own long range interception radar. In 1968 the Soviet government demanded a better-performing long-range interceptor and the ability to patrol alone in the northern Soviet Union. After evaluating the aircraft designed by the Tupolev Aircraft Design Bureau, the Yakovlev Design Bureau and the Mikoyan Design Bureau, the Soviet Defense Department finally decided to develop an all-weather model based on the MiG-25MP from the Mikoyan Design Bureau Interceptor to meet the demand. On 6 September 1976, Captain Viceroyellenko defected to his airport in Hakodate, Hokkaido, Japan, by piloting his MiG-25 / “Flying Fox” A fighter. May be as a confusing means, the Soviet factory will be the new “Fox bat” file number is set at 83. The earlier model was set at 84, Mikoyan design bureau will be the prototype of its name from MiG -25MP Ye-155MP. The main reason is related to Belenian defectors. In fact, Ye-155MP contains more design concepts than the MiG-25MP, including variable geometry wing. On the surface, the Ye-155MP is similar to the MiG-25, but the Ye-155MP has evolved into the MiG-31 and its aerodynamic profile has been improved in terms of structure, new weapon configurations and avionics Get very big improvement.
