FIELD: engines and pumps.
SUBSTANCE: utilisation method of residual liquid components of rocket fuel in spent stages of carrier rockets by their simultaneous supply to an afterburner at the step of lowering the stage with afterburning of residual fuel, after oxidiser ends, with air oxygen and by ejection of combustion products through side surface of the stage housing, according to the invention, ejection of combustion products is performed through convergent-divergent nozzles located in structural planes of the stage in the directions perpendicular to its longitudinal axis, and reaction forces occurring from convergent-divergent nozzles are used for changing angles of attack and wobbling of the stage housing and control of its lowering due to its aerodynamic quality of the stage housing.
EFFECT: invention provides utilisation of rocket fuel components by using their energy for control of the stage lowering.
