FLAME TUBE FOR COMBUSTION CHAMBER OF GAS-TURBINE ENGINE Russian patent published in 1995 - IPC

FIELD: aircraft engine engineering. SUBSTANCE: tube has casing 1 with cylindric bushings 2 for air supply. Each of the bushings is provided with end face deflector 3 having an opening whose axis is shifted with respect to axis 6 of bushing 2 in the direction opposite to the fluid flow. Opening 7 used for film cooling of casing 1 is made in side wall of bushing 2. The openings are arranged above deflector 3 and point in the direction of the fluid flow. Air, which flows through opening 7, pushes hot gases away from the inner surface of the tube at a part where protecting film of the main cooling system is absent resulting in protecting the tube against burn-out. EFFECT: enhanced reliability. 2 dwg
