发明名称	COMPRESSOR FOR GAS-TURBINE ENGINE
摘要	FIELD: non-positive-displacement pumps. ^ SUBSTANCE: compressor comprises inlet guiding vanes, working wheels, and guiding vanes of the compressor stages positioned in the flowing section. The working wheel of at least the first stage of the compressor has a conical bushing whose diameter increases downstream. The inlet guiding vanes and guiding vanes of at lest the first stage of the compressor have conical bushings whose diameter decrease downstream. D/d = 0.9-0.99 and D1/d1 = 1.01-1.1, where D is the diameter of the bushing of the working wheel at its inlet, D1 is the diameter of the bushing of the guiding vanes at its inlet, d is the diameter of the bushing of the working wheel of the compressor at its outlet, and d1 is the diameter of the bushing of the guiding vanes at its outlet. The conical surface of the bushing is inclined to the axis of the compressor at an angle of 1-6°. ^ EFFECT: enhanced reliability and efficiency. ^ 1 dwg
