Labyrinth seals axial compressors of gas turbine engines

摘要

The present utility model relates to mechanical engineering, mainly for aircraft gas turbine engines (hereinafter, CCD), and can be used in steam and gas turbines and for pumping gas blowers, etc. The technical result achieved when using the stated utility model is to reduce the weight and metal content, design simplification, simplifying manufacture, simplification of replacement response claimed labyrinth seal ring, and the relative ease of further processing. Said technical result is achieved in that the labyrinth seal is an axial turbomachine compressor comprising a sealing annular projections on the rotor and a response ring fixed on the steering apparatus, the response ring is made of fire-retardant plastic, such as polyamide or polyamide-imide.
