OPTIMIZATION OF THE LUNAR TRANS-EARTH INJECTION WITH THE MULTI-IMPULSE TRANSFER

The problem of the return from the Moon's artificial satellite orbit to the Earth is considered. The main goal is to develop and to implement the algorithm for the lunar trans-Earth injection's trajectory computation using three impulse maneuvers. The advantage of using the trajectory of multi-impulse transfer is that the total costs of the characteristic velocity in this case are less than the one-impulse transfer. Different schemes of the impulse maneuvers sequence are compared. The results of the numerical simulation for the three-body problem (the Earth, the Moon, the spacecraft) considering noncentral gravity models are presented.
