DEVICE FOR CONNECTING MIXER WITH HOUSING OF OUTER CIRCUIT OF DOUBLE- FLOW GAS-TURBINE ENGINE Russian patent published in 2005 - IPC

FIELD: aircraft engines.

SUBSTANCE: invention relates to devices for unit connections of housings of aircraft gas-turbine engines. Proposed device for connecting mixer with housing of outer circuit of double-flow gas-turbine engine contains connecting members secured on mixer with alternating air and gas channels. Said members are made in form of ring secured on mixer by means of suspension members in form of inclined walls with shelves rigidly secured on ring and mixer. Ring is installed relative to outer circuit of engine with ring-radial expansion clearance. Ring suspension members on mixer can be connected in pairs to each other by shelves secured on ring to form U-shaped common member whose middle shelf is located opposite to air channel of mixer. Ring suspension members on mixer can be interconnected by shelves to form corrugated belt. Ring is provided with longitudinal splines. Housing of outer circuit of engine is provided with mating splines. Ring radial expansion clearance is made on pitch circle of splines.

EFFECT: improved reliability of device for connecting housing of gas-turbine engine, provision of function of support of gas generator with preservation of parameters of air flow at mixer outlet.
