COMBUSTION CHAMBER OF A DUAL-MODE LIQUID PROPELLANT ENGINE, WORKING ON A GENERATOR-FREE SCHEME Russian patent published in 2019 - IPC F02K9/94 F02K9/97 

FIELD: rocket equipment.

SUBSTANCE: invention relates to missile technology, namely to liquid propellant engines. Combustion chamber of a dual-mode liquid propellant engine operating on a generator-free scheme, containing an annular combustor with a cooling path, service lines of fuel and oxidizer, a chamber block with a two-section supersonic nozzle with a cooling path, in the annular combustor, the mixing head with a two-cavity collector for supplying the oxidizer is made of two blocks, each of which works for its own nozzle section, and the service line of fuel through the cooling paths of the two-part nozzle and the cooling path of the chamber block is connected through the mixer and the turbine manifold to the fuel manifolds on the head blocks.

EFFECT: invention provides an increase in the specific impulse, a reduction in mass and an increase in the reliability of operation of the propellant engine.
