GAS GENERATOR Russian patent published in 2000 - IPC

FIELD: liquid-propellant rocket engines; gas turbine drives. SUBSTANCE: proposed gas generator has load-bearing shell. Outlet branch pipe connected with load-bearing shell and cover connected with load-bearing shell from side opposite to outlet branch pipe. Fuel space is made in cover. This space is arranged at outlet of fuel supply branch pipe and is placed in communication with fuel channels of mixing modules. Housing of each mixing module has fuel channel, mixing chamber and oxidizer ring channel arranged coaxially and communicating with mixing chamber. Bushing on inner surface of cover is arranged coaxially with load-bearing shell. Fire bottom placed in bushing forms space between fire bottom and cover. Chambers are made through fire bottom. Spacer is connected by one end to outlet branch pipe, and other end is connected with outer surface of bushing. Spacer is installed coaxially inside load-bearing shell forming a ring space in between. Space between cover and fire bottom communicates with oxidizer ring channels of mixing module through holes made in mixing module housing. EFFECT: improved reliability and efficiency of gas generator.
