Abstract

652,150. Gas turbine blades. ROLLSROYCE, Ltd. Oct. 16, 1947, No. 32201. Divided out of 652,099. [Class 110(iii)] Individual rotor blades 41 have roots with lateral flanges 45 which are held in opposed grooves in rotor elements 40. The blades are connected to the roots by stems of I-section comprising front and rear walls 43 and a central web. When the blades are assembled, the walls 43 and the platforms 42 form continuous annular surfaces. The blade stems are longer at the high-pressure end and, accordingly, the taper of the rotor disc is less than that of the floor of the working fluid passage. The stator blades may be similar but with platforms 48 extending over the tips of the rotor blades and shrouds 49 of U-section which, with the platforms 42, provide a continuous floor for the working fluid passage.
