FIELD: propulsion systems.
SUBSTANCE: invention relates to propulsion systems for spacecraft (SC). The proposed method includes the generation of laser radiation and its supply to the target. As a result of ablation, a flux of particles of the evaporated substance is formed from the target surface, which creates a thrust impulse of the spacecraft. The target is made of a substance with a high specific heat of vaporization (q=104–105 J/g) and is made in the form of a cone with an angle of 45–80° between its generatrix and the axis. The flow of particles is directed in the direction opposite to the direction of motion of the spacecraft by means of an annular reflector in the lower part of the engine.
EFFECT: ensuring the stability of the spacecraft in pitch and yaw, as well as a high thrust impulse (at a speed of the outflow of evaporated particles of 4-6 km/s).
