摘要
气动技术的研究对于认识空天飞行器飞行环境和发展其他关键技术有巨大推动作用。根据空天飞行器的任务环境及外形特点分析了空天飞行器研究涉及的高温/稀薄等复杂流动机理、复杂耦合环境下气动特性的预测与验证、大空域宽速域高升阻比气动布局设计等三个气动方面的关键问题,并探讨了解决上述问题所需开展的关键技术,为后续空天飞行器的研究提供了一定的指导与借鉴。
Research on aerodynamic problem and technology of aerospace vehicles has great impetus to the undestanding of the flight environment and other key technologies. Based on the characteristics of its mission and figure,the key aerodynamic problems of aerospace vehicles in three aspects are analyzed,including the mechanism of complex flow which coves high-temperature real gas effects and rarefied effects,aerodynamic performance prediction and verification under complex coupling environment,and aerodynamics configuration design in large airspace and wide velocity. Besides,the key technologies to solve these problems were discussed,which provide a little guidance and reference for the future study.
