以高超声速临近空间飞行器非开普勒轨道弹跳飞行为研究对象,论证了高超声速临近空间飞行器飞行轨道属于非开普勒轨道的研究范畴。首先给出了非开普勒轨道机动巡航段、再入段和再入瞬间的动力学方程;其次研究了再入瞬间高超声速临近空间飞行器的位置矢量求解问题,提出弹跳系数的概念;最后进行了仿真分析。仿真结果表明,非开普勒轨道动力学方程是正确的,弹跳系数是准确性的,从而说明了非开普勒轨道弹跳式远距离飞行方法是研究高超声速临近空间飞行器的一种新的有效途径。
Taking the non-Kepler orbit bounce flight near the hypersonic spacecraft as the research object, it is demonstrated that the orbital trajectory of the near-space hypersonic vehicle belongs to the non-Kepler orbit. Firstly, the kinetic equations of non-Kepler orbit maneuver cruise segment, reentry segment and reentry moment are given. Secondly, the position vectors of the near-space hypersonic reentry spacecraft are studied and the concept of bounce coefficient is proposed. Finally, Simulation analysis. The simulation results show that the non-Keplerian orbit kinetic equation is correct and the bounce coefficient is accurate, which shows that the non-Kepler orbital bounce long-range flight method is a new and effective method to study the hypersonic near-space vehicle way.
