GAS-GENERATOR MODULE Russian patent published in 2000 - IPC

FIELD: rocket manufacturing. SUBSTANCE: proposed gas-generator module for liquid-propellant rocket engines has cover, bottom and housing placed in between, mixing chamber made in bottom in place of housing installation, and fuel and oxidizer supply main lines. Housing has axial channel and longitudinal slots uniformly spaced over circumference of housing from bottom side for communication with mixing chamber. Blind axial channels of housing from cover side has tangential holes uniformly spaced over surface of housing and communicating with fuel supply main line. Space between bottom and cover communicates with oxidizer supply main line. Housing is provided with additional ring channel with tangential holes opening into space between cover and bottom and arranged coaxially with axial channel, and additional cylindrical mixing chamber being extension of additional ring channel. Additional mixing chamber communicates at one side with ring channel and axial channel, and at other side, with mixing chamber made in bottom. EFFECT: enhanced efficiency of functioning. 4 cl, 6 dwg
