| 摘 要： | 针对一些空间碎片飞行的形态特征,将高速碎片简化为一个后掠的飞片.在线化理论的假设下,对飞片进行了分区,并沿面积积分,求得了各区的压力系数,推导出了适用于前缘后掠、后缘后掠、平后缘的后掠飞片在超音速前(后)缘以及亚音速前(后)缘情况下的厚度波阻系数的表达式.得到了在超音速前缘和亚音速前缘两种情况下,飞片的厚度波阻系数随来流马赫数变化的规律.

| Abstract: | Considering the shape character of some hypervelocity space debris,the pressure coefficient was calculated using linearity theory by simplifying the hypervelocity space debris to be the sweepback wing,and integraling along the subarea.The calculating formulas of the thickness wave drag coefficient for the leading edge sweepback,trailing edge sweepback and flat trailing edge of the supersonic leading edge or subsonic leading edge were given,and the relationship between the thickness wave drag coefficient and coming flux Mach number was demonstrated. |
