MULTI-CHAMBER LIQUID ROCKET ENGINE WITH THE GENERATOR GAS AFTERBURNING Russian patent published in 2018 - IPC F02K9/60 F16L27/04 

FIELD: rocket equipment.

SUBSTANCE: invention relates to the rocket equipment and can be used in the rocket propulsion systems with liquid rocket engines (LRE) manufacturing. Multi-chamber LRE with the generator gas afterburning includes at least two mounted on the frame combustion chambers, a turbopump unit, a gas generator and a gas duct, whose single end portion is connected to the turbine outlet, and the gas duct other ends are connected to the respective chambers through the bellows compensators, which are the chambers tilting units, wherein these areas of the gas duct are attached to the frame sections, wherein the gas duct to the frame mounting unit includes two ball bearings, diametrically located relative to the gas duct axis, installed on the covering the gas duct bearing ring, and rigidly fastened thereto, which are installed in the attached to the ring cups, at that the ball bearing head is clamped between the thrust bearing and the adjustment washer, and the bearings tightening is performed with the screwed onto the ball bearing cup cap nut, at that, the ball bearings end sections are screwed into the frame additional bearing plates threaded holes, which are connected to the rocket frame through the bearing rods.

EFFECT: invention enables the engine design simplification, its weight reducing and reducing the gas ducts assembly with the engine frame complexity.
