摘要:

在多年来的亚音扩压器研究成果的基础上,提出了亚音速飞行器进气道内通道优化设计的概念,并介绍了亚音速飞行器进气道内通道设计及性能计算软件的功能。实践表明,该设计及性能计算软件可用于亚音飞行器进气道内通道的设计选型,从而减少或替代实验选型,节省费用,缩短研制周期。

Abstract:

In this paper, an idea of optimum design concerning a subsonic inlet duct is proposed on the experimental investigations of subsonic diffusers in past years. A-nd the function of the program about the design and calculation of performa.nce of the subsonic inlet duct is described. The experimental results obtained in. practice show that the prpgram can be used in the earlier stage of the design of the inlet to replace or reduce the experiments for model selecting, so the experimental expenses and time for design can be greatly reduced.
