Constant pressure ratio maintenance device for rocket engine - includes additional lasers cooperating with successive flow interception grids in downstream direction for energy leakage recovery

摘要

A first grid (8) associated with two laser (3, 4) stores the laser beam energy and is opened and closed to prevent suction of the high-pressure medium into the vacuum. Two additional lasers (6, 7) are associated with second and third grids (9, 10) operating on an electro-vacuum basis, intercepting the flow into the thrust nozzle (2) so that leakage of energy from the first grid (8) is recovered and returned to the upstream laser (3). ADVANTAGE - Energy losses at grid are reduced so that compensation by high-power generator is unnecessary even at extreme pressure differences.
