These tools permitted the minimization of interferencedrag and also facilitated the design of the engine nacelle and thrust reverser.
这些先进工具的使用，使得干扰阻力被降至最低，改善了发动机吊舱和反推装置的设计。

Experiment investigation shows: The main body zero drag can be reduced by faovurable interference of jet flow. Then an optimuns afterbody configuration can be obtained.
