These tools permitted the minimization of interference drag 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.

实验研究表明，利用喷流的有益干扰，可使主弹体零阻显著下降，从而得到一种优化的后体外形。
