METHOD FOR CLEANING OF ROCKET SEPARATING PART FROM LIQUID TOXIC REMAINS OF ROCKET FUEL COMPONENTS AND DEVICE FOR ITS REALISATION

摘要

FIELD: aviation.;SUBSTANCE: invention is related to rocket space engineering, namely to carrier rockets with liquid rocket propellant engines. Method for cleaning of rocket separating part from liquid toxic remains of rocket fuel components on passive area of flight is based on gasification of fuel remains in fuel tank and their supply through manifolds by means of connection pipelines into oxidant tank and then to surrounding space. Device comprises displacement reservoir with filling-drain valve, ball-balloon, pyrovalves, pyromembrane, powder rocket engines for untwisting of rocket separating part body, control unit. Device additionally comprises connection pipelines with pyromembranes, flow pipeline of oxidant upstream main oxidant valve, drain valve, which is installed on upper bottom of oxidant reservoir, reduction gear connected to electric pneumatic valve and displacement reservoir.;EFFECT: possibility is achieved to preserve specified coordinates of fall regions and to reduce ecological effect of separating parts, which use toxic components of rocket fuel.;3 cl, 1 dwg
