FIELD: rocket engineering.
SUBSTANCE: group of inventions relates to aerospace engineering. Method for gasification of the residual liquid fuel component (FC) in the tank of the carrier rocket (CR) burned out stage is based on the supply of hot gases (of coolant) to the fuel tank and discharge of gasification products (GP) after reaching a given pressure in the fuel tank. In addition, a predetermined thermodynamic state of the GP is ensured, eliminating the transition of cryogenic FC from the gas phase state to the liquid phase and the solid one when moving in the drainage system when the GP is discharged from the fuel tank. Gases supplied to the fuel tank are obtained in an autonomous gas generator (AGG), while solid fuel gas generating compositions (SFGGC) are selected from the conditions of chemical neutrality between the combustion products of SFGGC and gasified GP. Device for implementing the method includes a fuel tank, AGG for producing hot gases (coolant), a coolant supply line, a drainage system and a heat bridge, which is additionally introduced between the AGG and the drainage system. Location of the AGG is selected in the immediate vicinity of the drainage system.
EFFECT: technical result of the group of inventions is to ensure the explosion safety of the exhausted stages of CR and accident-free operation of the fuel tank.
