通过分析采用多圈飞行Lambert解的双脉冲交会的特征速度与转移轨道半长轴的关系,指出其最优解实际上是2N+1条满足时间约束的转移轨道中燃料较省的,而非最省燃料轨道.提出将双脉冲交会的首次脉冲矢量分解成方向相同的两次脉冲,使得追踪器在特定的滑行轨道飞行N圈以消耗多余的转移时间,利用剩余的转移时间沿最省燃料轨道与目标交会.几何上证明了这种交会的特征速度与最省燃料转移相同,并且给出了解的存在性条件.通过仿真验证了这种交会比采用多圈飞行Lambert解的双脉冲交会更省燃料,解的存在性对转移时间的长度要求更低.
By analyzing the relationship between the characteristic velocities and the semi-major axis of the transfer orbits of a multi-turn flying Lambert solution, it is pointed out that the optimal solution is actually 2N + 1 fuel in the transfer orbit which satisfies the time constraint rather than the fuel. The most fuel-efficient orbit, proposes to decompose the first pulse vector of the double-pulse rendezvous into two pulses of the same direction so that the tracker will fly N cycles on a specific orbit to consume the extra transfer time and utilize the remaining transfer time along the most fuel-efficient Orbit and the target intersection.It is geometrically proved that this kind of rendezvous is characterized by the same characteristic speed as the most fuel-efficient transfer and the existence conditions of the solution are given.It is proved through simulation that the rendezvous is more efficient than the two-pulse rendezvous Provincial fuel, the existence of the solution requires less transfer time length.
