Abstract
863,555. Axial-flow compressors; gas turbine plant. DAIMLER-BENZ A.G. March 17, 1958 [March 15, 1957], No. 8501/58. Classes 110 (1) and 110 (3). A gas turbine plant comprises an axial flow compressor and turbine, each of which consists essentially of only two contra - rotating rotors situated one directly behind the other, one of the compressor rotors operating partly in the subsonic and partly in the supersonic range while the second compressor rotor operates only in the supersonic range. In the gas turbine engine shown, axial flow compressor rotors 5, 6 are driven in opposite directions by oppositelyrotating turbine rotors 9, 10. Rotor 6 is of supersonic type, while rotor 5 is of transonic type, the latter type being defined as one in which a part of each blade works in the supersonic range and the remaining part works in the subsonic range, the flow to the blading taking place at velocities of about unity Mach number. Subsonic guide blading 7 is provided. Rotor 5 may be preceded by inlet guide blading. The stage head of rotor 5 decreases radially outwardly, while that of rotor 6 increases radially outwardly, the total head of the two rotors being radially constant.
