一般形式的共振轨道研究

为了利用较小的推力使航天器的轨道产生较大的变化，可以利用共振原理来研究航天器的运动，称这样一类非开普勒轨道为共振轨道。将圆频率作为变量，通过合理地选择轨道描述参数、时间尺度和推力描述方式建立了一般形式的共振轨道模型，并基于仿真分析研究了共振轨道圆频率对共振轨道的影响。通过对地球——火星共振转移轨道的算例进行仿真分析，初步研究了共振轨道在星际探测轨道设计中应用的效果。研究结果表明：圆频率改变将对推力峰值产生影响；共振轨道在星际探测中的应用是可行的，并且在能量消耗方面优于Lambert 轨道。

GENERAL FORM RESONANCE ORBITS

In using the resonance theory to study the motion of a space vehicle, the corresponding non-Keplerian orbits are named the resonance orbits. In this paper the general dynamical model for resonance orbits is established through a judicious choice of orbit parameters，the time scale，and the thrust representation. An analysis of the influence of the resonance frequency is made based on simulations. The possibility and the effect of the resonance orbits to be used in the deep space exploration through analyzing an Earth-Mars mission are explored. It is shown that, changing the circle frequency will influence the peak thrust; it is possible to use the resonance orbits in the deep space exploration, and its energy consumption is less than using a Lambert orbit.
