Abstract

The opportunity of use of Moon swingby is researched at realization of a trajectory of interplanetary flight. It is researched the flight plan at which due to a velocity impulse at low Earth circular orbit a spacecraft (SC) gets in a vicinity of the Moon, before to ins ert in to a heliocentric trajectory of flight. Due to Moon's swingby a spacecraft gets additional velocity, which allows reaching a planet of destination with smaller expenses of characteristic velocity of a chemical upper stage. In work the detailed analysis of the scheme of flight and the strict proof of possible existence of several types of trajectories of a space vehicle with lunar gravitational maneuver is given.
