FIELD: engines and pumps.SUBSTANCE: method for organisation of working process in laser rocket engine involves supply of working medium to absorption chamber, creation of plasma nucleus in it by focusing a laser beam and initiating continuous optic discharge, heating of working medium that flows around the nucleus, and when it leaves the supersonic nozzle, it creates plasma jet. When long-focal-length optic system is used, at least two continuous optic discharges are initiated in series; the first optic discharge is initiated in laser beam focus, and the next ones are initiated in plasma trace along emission axis by supplying metal ion sources to it. There is also laser rocket engine implementing the proposed method, which includes laser emission source, system of turning and focusing mirrors, absorption chamber with focusing lens, nozzle, working medium supply system to absorption system, which differs by the fact that at least two wire ends from highly ionised metal are located in focus of long-focal-length lens and in series along axis of absorption chamber.EFFECT: increasing specific impulse and efficiency of laser rocket engine and its operating life.4 cl, 2 dwg |
