mechanical engineering; engines. SUBSTANCE: proposed gas-turbine engine has sealing device arranged behind compressor. Sealing device is made in form of peripheral and internal seals arranged at different diameters to form behind-compressor unloading space. The latter is connected with compressor setting at inlet through peripheral seal, and at outlet it is connected both with discharge space through internal seal and with gas space through bushings arranged between walls of manifold formed by cellular flange and deflector. Intensifiers in form of ring triangular grooves in section are made on cooled surface of cellular flange in peripheral seal. EFFECT: increased economy owing to provision of behind - compressor unloading space. 3 dwg |
