CHAMBER OF LIQUID PROPELLANT THRUSTER Russian patent published in 2002 - IPC

FIELD: rocketry. SUBSTANCE: proposed chamber of liquid propellant thrust has housing and mixing head with bipropellant centrifugal injector arranged along its axis. Inner and outer vortex chambers of centrifugal injector are connected with corresponding components supply channels and with peripheral spray injectors communicating with supply channels of fuel component to outer vortex chamber. Inner vortex chamber and tangential channels to supply fuel component into chamber are made in rod sealed in housing coaxially with outer vortex chamber. Tangential channels of inner vortex chamber are located in zone of plane passing through tangential channels of outer vortex chamber. EFFECT: improved efficiency of working process in combustion chamber, reduced labor input in manufacture of centrifugal injectors. 2 cl, 2 dwg
