摘要
F-22战斗机从80年代预研到原型机阶段以及目前的工程和制造发展阶段,其结构材料的选择经历了许多变化,分析它的变化原因是很有意义的。影响材料选择的因素首先是非常规机动能力带来的减重要求。这种在过失速条件下仍能作可控机动飞行的能力。
Since the. beginning of F-22 development, it had been considered as a testbed of new materials . Many new materials were developed and tested in order to meet the needs of the next generation fighter's characteristics, such as unconventional maneuver, supersonic cruise and stealthy. In this part, the author introduced these materials used in YF-22, F-22's prototype and EMD F-22 and analyzed why different materials were used in them .
