月球近旁转向技术研究

A STUDY ON LUNAR SWING-BY TECHNIQUE

通过月球近旁转向 ,可以改变航天器的对地速度大小和方向。借助圆锥曲线拼接法可以对月球近旁转向问题进行初步分析。研究表明 :利用月球近旁转向技术发射地球静止卫星和逆向卫星可以节省速度增量 ,发射场的纬度越高 ,节省的速度增量越多。

Magnitude and direction of geocentric velocity of spacecraft can be changed after a lunar swing by.Patched conic technique can be used for preliminary analysis of lunar swing by.It is indicated that using lunar swing by technique can reduce velocity increment needed for launching geostationary satellite and reversed satellite.The higher the launching site is,the more velocity increment is saved.
