COMBINED ENGINE UNIT OF ROCKET POD Russian patent published in 2015 - IPC F02K9/42 

FIELD: engines and pumps.

SUBSTANCE: in a combined engine unit of a rocket pod, which includes tanks for cryogenic fuel components 1, liquid-propellant sustainer with a turbo-pump system for supply of cryogenic fuel components to regeneratively-cooled chamber 2, impulse engines of a system of stabilisation, orientation and start 3, which use gaseous fuel components, tanks 4 for gaseous fuel components of impulse engines 3; tanks are located near the tanks under heat insulation 5 that is common for them; with that, tank walls are connected to walls of tanks with thermostats 6 with the specified length and cross-sectional area; cavities of tanks of each of the fuel components are interconnected through mixers 7 and pipelines 11, 12 with cut-off valves 9, 10, with outlets of the corresponding fuel components from pumps of turbo-pump unit 8 and cooling circuits of chamber 2, and in the tanks there installed are pressure sensors 13 and temperature sensors 14 of gaseous fuel components, which perform a function of sensitive elements of the control system of the rocket pod.

EFFECT: improving reliability of engine units of rocket pods using liquid cryogenic fuel components.
