Abstract

805,330. Gas turbine plant. ROLLSROYCE Ltd. July 20, 1955 [Aug. 13, 1954], No. 23657/54. Class 110 (3). Air pressure is applied to the surfaces of gasturbine discs for axial-load balancing. As described, air from the compressor enters a chamber 25 ahead of the HP disc 10 and passes through ports 32 and bore 34 to a chamber 35 ahead of the LP disc 15. (The pressure in chamber 35 may be e.g. four fifths of the pressure in chamber 25.) Air also leaks through the labyrinth seal 37 to a chamber 39 at the back of the HP disc (where it may be at half the pressure of chamber 35), thus providing a pressure drop across each disc for balancing axial loading due to the compressor. Pressure-air leaks through the outer labyrinth seals 28, 43, 50 to prevent hot gases flowing inwardly.
