METHOD AND DEVICE FOR OBTAINING THRUST (VERSIONS) Russian patent published in 1997 - IPC

FIELD: rocketry; space engineering; aeronautical engineering. SUBSTANCE: method consists in generating high-pressure and high-temperature combustion products, accelerating them to required speed corresponding to supercritical pressure differential followed by efflux of jet to surrounding medium and blowing the gas into peripheral part of overexpanded or rated jet; simultaneously with blowing the gas, ejection section of jet is screened and blow is effected by mass which is no less than associated mass of screened section of jet. Device for realization of this method is made in form of rocket engine 1 whose nozzle unit is provided with profiled cowling 2 with gas supply system 6 in direction of engine axis; system is provided with lateral shield 3 and bottom shield 4 articulated on it forming receiver 5 between shield 4, cowling 2 and lateral shield 3. EFFECT: enhanced reliability. 4 cl, 7 dwg
