LIQUID ROCKET ENGINE CHAMBER ROCKING ASSEMBLY WITH GENERATOR GAS AFTERBURNING Russian patent published in 2019 - IPC F02K9/66 

FIELD: machine building.

SUBSTANCE: invention relates to the field of power machine building and concerns liquid rocket engine (LRE) chamber rocking assembly with generator gas afterburning. Liquid rocket engine chamber rocking assembly with generator gas afterburning comprises bellows compensator consisting of bellows with support rings, wherein one of the rings is connected to the gas duct housing, and the other ring is connected to the combustion chamber housing shell, wherein the bellows from the outside is provided with power rings inserted into the corrugation recesses, and on the inner side of the bellows there are two thin-walled metal screens cantilever attached to the support rings, wherein the free ends of the screens are inserted into each other with a radial gap, at the outer side of the bellows there is a cardan containing a ring, into which spherical sliding bearings and bushings are inserted, forming two rotary axles, on which the forks are rotated, the end sections of which are attached to the support rings, wherein cardan forks and support rings of bellows of rocking assembly are made solid-cast from steel VNS-25, and joint of rocking assembly with shell of combustion chamber housing includes weld seam on external surface of connected shells, locking connection made on inner surface of connected shells, and annular cavity between them, at that, in one of lock parts radial holes are made to connect annular cavity with combustion chamber inner volume that is connected with protective gas system.

EFFECT: invention provides simplified design of joint between swing assembly and combustion chamber housing, reduced weight of rocking structures.
