DEVICE FOR REGENERATIVE COOLING OF SUPERSONIC PART OF LIQUID ROCKET ENGINE NOZZLE Russian patent published in 2019 - IPC F02K9/64 

FIELD: rocket equipment.

SUBSTANCE: invention relates to aerospace engineering and can be used for cooling liquid-propellant jet nozzle supersonic part. Device comprises heat carrier tank, equipped with valve and filling line, an exhaust branch pipe with a valve or a receiver and a heat carrier circulation circuit consisting of a cooling circuit for supersonic part of the nozzle, a check valve, a turbine, the main heat exchanger, a pump, a common turbine shaft and a pump and connecting lines. At that, in heat carrier circulation circuit between pump and cooling channel of nozzle supersonic part additional heat exchanger is installed, which is intended for transfer of heat carrier, which left the pump, into gaseous state with heat carrier, which has passed turbine.

EFFECT: invention provides for reduction of non-uniformity of cooling of walls of the nozzle supersonic part with preservation of low pressure in its cooling circuit.
