GAS-TURBINE ENGINE COMBUSTION CHAMBER Russian patent published in 1997 - IPC

FIELD: manufacture of engines. SUBSTANCE: flow of cooling air from air chamber 3 of combustion chamber enters cyclone chamber 9 through hole 11 where cyclic motion is effected and air flows around inner surface 13 of chamber 9, thus cooling it. Surface 14 directed to gas chamber 7 is cooled due to convective transfer of heat. Then air enters next cyclone chamber (in way of motion) via tangential passages 10 where it rotates, thus cooling surface 13. Air escaping from last cyclone chamber enters slit 12 forming film obstacle, thus cooling surface 14 of segment 5 on side of gas flow 8. EFFECT: enhanced efficiency. 2 cl, 5 dwg
