FIELD: motors and pumps.
SUBSTANCE: power pack comprising the tanks with circuits 1, 2, boosting system 3, gas-producer 4 with ignition device 5 for transforming of liquid cryogenic oxidant into gaseous oxidant with preset temperature and storage receiver 6 for gaseous oxidants as a fuel for motor units 7, contains the heat exchanger 8 for transforming of liquid cryogenic fuel into gaseous fuel with heating up to preset temperature comprised by heat transfer path into the circuit downstream the gas-producer 4, by the heat receiving path - into the circuit for supply of cryogenic liquid fuel, storage receiver 9 for gaseous combustible fuel for power supply of motor units 7, comprised in the circuit downstream the heat receiving path of the heat exchanger 8, gas liquid mixer 10, comprised in the circuit between the output of the heat receiving path of the heat exchanger 8 and input of the storage receiver 6 for gaseous oxidants, meanwhile the fluid input of the mixer 10 is connected with the circuit of liquid oxidant supply to the gas-producer through the pipeline 11 with the adjusting throttle washer 12 installed.
EFFECT: improvement of reliability of power packs of reaction control systems using liquid cryogenic fuels.
