摘要
为了提高飞行试验进气道的起动能力,减小进气道研究的模型尺度影响和天地差异,吸气式高超声速飞行器需要在进气道上安装强制转捩装置。通过对国内外高超声速进气道强制转捩装置的设计方法、选型、风洞试验和飞行试验的回顾和分析,介绍了转捩装置设计的五个主要问题:强制转捩装置的转捩机理、安装位置、选型和几何参数优化、天地相关性。并对未来的主要研究方向提出了建议。
In order to improve the starting ability of inlet in flight test,reduce the effect of model size and the difference between flight and ground testing,it is necessary to install the forced-transition trip on in-let of air-breathing hypersonic flight vehicles.Through the review and analysis about the design,screening, wind tunnel test and flight test of forced-transition trips at home and abroad,the five main problems are in-troduced.The five problems are the mechanism of transiton caused by forced-transition trip,install position and geometrical parameters of the trip,influence of the trip on the inlet performance,and the correlation a-nalysis of aerodynamic data between flight and ground prediction for the forced-transition trip.The recom-mendations are given for the future research directions.
