RING COMBUSTION CHAMBER OF GAS TURBINE ENGINE Russian patent published in 1996 - IPC

FIELD: gas turbine engine engineering. SUBSTANCE: engine has compressor 1 with diffuser 2 having ring outlet part 3. In operation of the combustion chamber air outflows from the outlet part 3 that encloses head part 9 of fire pipe 5 and enters ring space 14 cooling a part of housing 4 and changing its direction with deflector 7. The air is then flows around fire pipe 5 head part 9 of which rigidly secures to front end 11 of ring screen 6 between housing 4 and fire pipe 5 through intermediate members 10. Inflowing in fire pipe 4 through openings provided in its wall, air takes part in combustion of fuel, dilution of combustion products, and film cooling of the wall of fire pipe 4. Fuel is fed in so doing by nozzles 8 uniformly arranged over periphery at head part 9 of fire pipe 5. EFFECT: enhanced reliability. 3 cl, 3 dwg
