Abstract
722,001. Turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 6, 1952 [March 9, 1951], No. 5775/51. Class 110 (3). In a single-stage turbine the row, or in a multi-stage turbine the last row, of rotor blading which is of aerofoil form and substantially cambered is followed in the direction of fluid flow by an immediately adjacent row of stator blades, also of aerofoil form, which are in number a substantial proportion of the blades in the rotor row and have a low camber compared with, and not greater in chord than, the blades of the rotor row. It is stated that the presence of the stator blades reduces the secondary losses in the rotor blades and provided that the losses in these blades are not too high this will result in an increase in turbine efficiency. The invention is described with reference to a gas-turbine jet-propulsion plant having a row of nozzle blades 13, a row of rotor blades 2 and a further row of stator blades 15. In this arrangement the gases enter the blades 15 with a purely axial velocity so that these blades are of a symmetrical streamlined section and are untwisted. The chord of the blades 15 is less than that of the blades 2. In a modification the blades 15 are given a slight camber to remove any whirl velocity in the exhaust gases leaving the blades 2. The blades 15 may be used to support the exhaust cone from the turbine casing.
