GAS TURBINE ENGINE SEALING DEVICE Russian patent published in 2000 - IPC

FIELD: aircraft industry; gas turbine engine behind-the-compressor sealing devices. SUBSTANCE: sealing working medium flowing through sealing device through slot channel 11 and mixing space 15 into low-pressure space B from high-pressure space Б creates rarefaction at inlet of mixing space 15 and low-temperature cooling air from slot-like space A is entrained through channel 14 into low pressure space B. EFFECT: increased economy of gas turbine engine owing to provision of minimum size of radial clearance at all operating conditions of engine and gas jet ejection at outlet of sealing device. 2 dwg
