FIELD: space recoverable launchers of 1.5-stage arrangement with mixed engine plant.
SUBSTANCE: proposed device includes recoverable transport vehicle with at least one main rocket engine, propellant and oxidizer tanks for delivery of components for this engine and one or several expendable rocket boosters secured to transport vehicle. Oxidizer tank is connected with main rocket engine and combustion chamber (chambers) of rocket booster (boosters) by means of oxidizer supply devices. Combustion chamber is mainly hybrid combustion chamber supplied with gaseous oxidizer. Oxidizer supply system is provided with booster pumps (where liquid oxygen is gasified) and turbo-pumps mounted in gaseous oxidizer pipe lines. Provision is made for independent adjustment and disconnection of turbo-pumps. At the end of acceleration of vehicle, combustion chamber of expendable boosters are disconnected from oxidizer supply system and boosters are jettisoned. Propellant tanks, pumps and pipe lines are kept for repeated use.
EFFECT: simplified construction; low expenses for launching.
