INCREASED HEAT EXCHANGE SURFACE LIQUID ROCKET ENGINE CHAMBER Russian patent published in 2005 - IPC

FIELD: rocket engineering.

SUBSTANCE: increased heat exchange surface liquid rocket engine chamber provided with combustion chamber cooled by fuel, has ring-shaped mixing head and internal and external cooled cylinders disposed coaxially. Edge of each cylinder is connected with ring-shaped mixing head. The other end of internal cooled cylinder is connected with nozzle cooled by fuel. External side surface of additional cooled cylinder adjoins internal side surface of internal cooled cylinder. One edge of additional cooled cylinder is connected with nozzle and the other end is connected with edge of internal cooled cylinder, which edge is disposed in opposition being connected with mixing head. Cooled bottom is placed in opposite to mixing head and is connected with edge of external cooled cylinder. Liquid rocket engine sis connected in gas generator-free circuit and specific weight of propulsion is improved due to usage external cooling of fire walls of chamber.

EFFECT: reduced size of liquid rocket engine chamber; simplified service between flights; better quality of diagnosing of defects.
