为了对付明天的威胁——F-22最新进展系列报道之一

To Counter Tomorrow Threats -Recent F-22 ' s Series Report (1)

目前,F-22已经完成了初步设计评审(PDR)阶段,开始工程和制造发展(EMD)样机的制造,预计在1997年5月首飞(请参看本期“F-22的试飞将采用一系列创新举措”一文).从现在公布的EMD F-22与YF-22相比,外形和性能都有不少改变.我们根据美国《航空周刊与航天技术》杂志与其他资料,将EMD F-22的主要变化进行综合归纳,分3期向读者介绍.我们可以从国外对下一代先进战斗机作战环境分析、设计思想、先进技术的采用等一系列基本想法中得到有用的启迪.

The F-22 successfully passed its Preliminary Design Review ( PDR ) and began to produce Engineering and Manufacturing Development (EMD) aircraft. Externally, EMD F-22 appears similar to YF-22 prototype. However, there are some significant differences. From this issue to the Dec. issue, we will serially introduce EMD F-22 ' s figures based on the data from recent AVIATION WEEK & SPACE TECHNOLOGY issues and another material.
