摘　　要：为了实现同平面气动辅助空间交会,首先分析了其必须满足的2个必要条件:轨道转移问题和调相问题。然后分析了同平面HEO-LEO霍曼轨道转移技术及其调相问题。最后通过应用最优控制理论,求解一个典型同平面高轨道向低轨道转移的最优轨迹,确定了OTV在大气作用阶段轨道相角的变化大小。进一步依据空间交会理论得到了同平面HEO-LEO气动辅助空间交会所必须满足的标准相角的计算公式,并分析了气动辅助空间交会的调相问题。最后将霍曼方法和气动辅助方法进行了比较,得出了气动辅助空间交会不但可以节省燃料,而且能够在合理的时间内实现空间交会的结论。Two necessary techniques, orbital transfer and phasing were introduced for coplanar aeroassisted space rendezvous. The Hohmann orbit transfer technique for coplanar high earth orbit-low earth orbit（ HEO- LEO） transfer and its phasing were analyzed. The coplanar HEO-LEO aeroassisted orbital transfer technique was studied in detail. The optimal control theory was applied to resolve a typical optimal trajectory of the aeroassisted orbital transfer from a HEO to a LEO and the orbital phase angle of the OTV flying in the atmosphere was obtained. Based on the space rendezvous thcory, a calculation expression of the standard phase angle that must be complied with for the coplanar HEO-LEO aeroassisted space rendezvous was derived and the phasing problem of the aeroassisted space rendezvous was analyzed. The Hohmann technique and the technique were compared and concluded that the latter can not only save the fuel but also rendezvous in a reasonable time.
