FIELD: engines.
SUBSTANCE: invention relates to electric rocket engine used to control spacecraft movement in space, including orbital maneuvers. Electric rocket engine has, as a variant, photoemission cathodes – electron sources for neutralization of the ionised working medium, light detector photodetector for control of engine operation modes, energy recuperation device.
EFFECT: technical result is higher efficiency of using electric energy and power efficiency of engine by using energy of light flux from ion torch and neutral atoms (molecules) to ensure engine operation.
