一、引言 随着航天飞行器的发展,稀薄气流中热交换实验研究工作也得到了相应的发展。对于平板,球,钝柱,尖、钝锥,三角翼等简单体,国外已做了大量的研究工作,这对于稀薄气体动力学的基础理论研究和工程设计都是有益的。 由于简单体的稀薄气动特性具有一定的典型性,理论上对它进行严密的分析存在一定的困难,因此,作为实验研究计划的一部分,在低密度高超音速风洞中进行了零攻角平头圆柱和半锥角10°尖锥等三个模型的热交换实验研究。 I. INTRODUCTION With the development of spacecraft, experimental research on heat exchange in lean air has also been developed accordingly. For the simple body such as flat plate, ball, obtuse column, pointed, blunt cone, delta wing and so on, a great deal of research work has been done abroad, which is beneficial to the basic theory research and engineering design of lean gas dynamics. Because of the typical aerodynamic characteristics of a simple body, it is difficult to theoretically analyze the lean aerodynamic characteristics. Therefore, as part of the experimental research project, And half-cone angle 10 ° cone three models of heat exchange experiments.
