本文首先简要介绍回收型卫星重返大气层概貌。从工程设计角度出发论述卫星再入舱气动外形设计依据,评述美、苏两国现有空间再入飞行器外形的特点,然后论述卫星再入舱与导弹再入弹头的主要差别,指出再入舱特有的主要空气动力学问题。最后展望回收型卫星气动外形未来发展趋势,推荐一种有发展前途的新型再入舱气动外形—平头双锥体。
This article begins with a brief overview of the return satellite to return to the atmosphere overview. From the point of view of engineering design, this paper discusses the design basis of the aerodynamic design of the satellite reentry module, reviews the features of the existing space reentry aircraft in the United States and the Soviet Union, then discusses the main differences between the satellite reentry module and the missile reentry warhead, Unique main aerodynamic problems. Finally, the future development trend of recovery aerodynamic profile of satellite is proposed, and a new aerodynamic shape of reintroduction cabin with a promising future is proposed - flat bipyramid.
