A ground fire circulation orbit design method based on aerodynamic force assistance comprises the steps that the circulation period T, the transfer time TEM from the earth to the Mars, the initial phase angle phi E0 of the earth, the initial phase angle phi M0 of the Mars and the transfer time TME from the Mars to the earth are determined, and the following relation is met: TEM + TME = T; according to the Lanbert equation, the speed VEout starting from the earth, the speed VMin approaching the Mars, the speed VMout starting from the Mars and the speed VEin returning to the earth are calculated; the approaching speed and the leaving speed of the aircraft relative to the Mars and the approaching speed and the leaving speed of the aircraft relative to the earth are determined, and after pneumatic turning conditions are verified to be met, the ground fire circulation orbit is determined.

    一种基于气动力辅助的地火循环轨道设计方法,包括:确定循环周期T、地球到火星的转移时间TEM、地球初始相位角φE0、火星初始相位角φM0、火星到地球的转移时间TME,且满足如下关系:TEM+TME=T;根据兰伯特方程,计算出从地球出发的速度VEout、接近火星的速度VMin、从火星出发的速度VMout、返回地球的速度VEin;确定飞行器相对火星的接近速度和离开速度,以及飞行器相对地球的接近速度和离开速度,验证满足气动转弯条件后,确定地火循环轨道。
