Abstract

692,355. Axial flow compressors; gas turbines. ROLLS-ROYCE, Ltd. Feb. 15, 1951 [Feb. 28, 1950], No. 5129/50. Classes 110(i) and 110(iii) [Also in Group XXIX] In a multistage axial flow compressor, the inlet stator blades are automatically adjusted in accordance with the compressor speed and intake temperature. As shown, the inlet blades 10, 11 of compressor 14 are adjusted, in opposite directions by the hydraulic jacks 22, 23, the supply.of pressure fluid to which, is controlled in accordance with the compressor speed and intake temperature. The supply of pressure fluid through pipe 39 from the fuel supply 24 to the jacks is maintained by pump 26 driven from the main shaft 19. The control of the pressure fluid to each jack is effected by a diaphragm valve which is adjusted by the pressure difference developed across an orifice 68 by the flow of fuel through it, maintained by the pump 64 driven from the shaft 19. The orifice size is charged in accordance with the intake temperature. Specification 704,849 is referred to.
