在即将出台的联合先进攻击技术(JAST)计划的动力装置竞争中,衍生型发动机目前占领先地位。想为JAST提供全新设计发动机的主张恐怕要经历一场艰苦的鏖战。JAST的项目负责人称,从经费及性能角度考虑,确实不需研制全新的发动机。对于单发JAST飞机最佳选择可以是以普惠公司的F119或GE公司的YF120为基础发展的衍生型发动机。若JAST飞机采用双发布局,GE公司的F414发动机也可作为候选动力装置。衍生型发
Derivatives are currently leading the race for power units in the upcoming Joint Advanced Attack Technology (JAST) program. I am afraid to go through a tough fierce battle to provide JAST with a completely new design engine. JAST’s project manager said that from the financial and performance point of view, does not need to develop a new engine. The best choice for a single JAST aircraft can be a derivative engine based on Pfizer’s F119 or GE’s YF120. If JAST aircraft with dual launch, GE’s F414 engine can also be used as a candidate power plant. Derived hair
