METHOD AND DEVICE FOR LUNAR SPACE POWER SUPPLY Russian patent published in 1997 - IPC

FIELD: power supply by means of space lunar power antenna in the form of multibeam active phased antenna array radiating microwave energy obtained by conversion of energy from solar batteries. SUBSTANCE: according to invention, lunar power transmitting antenna is divided into two separate parts. One of them is used to transmit microwave energy to ground receiving power stations (rectennas) installed on Earth's side invisible from Moon and other part is used to transmit microwave energy to space near-earth orbital secondary reflector to be transmitted from them due to secondary reflection to ground receiving power stations (rectennas) installed on Earth's side invisible from Moon. EFFECT: provision for compatibility of rectennas mounted on Earth's sides visible and invisible from Moon as well as between them and space solar-electric power stations of earlier design as far as their dimensions are concerned; reduced size of near-earth space orbital secondary reflectors retaining high efficiency of microwave energy transmission from Moon to ground and near-earth space power consumers, simplified functioning and phasing procedures, reduced scanning angles of two newly introduced parts of common lunar power antenna. 2 cl, 3 dwg
