Abstract

891,739. Turbine blades. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Sept. 5, 1960 [Sept. 30, 1959], No. 33169/59. Class 110 (3). [Also in Group XXII] A turbine or compressor rotor is made up of at least two sheet metal laminµ 1, the adjacent faces thereof being in contact with one another over their whole extent and being formed with circumferentially extending interengaging grooves 3. The laminµ 1 taper in thickness towards the rim and the end laminae of the pack also have circumferential grooves. These grooves engage with corresponding grooves in bosses 4 and in annular side plates 8. The whole assembly is held together by rings of bolts 6, 9 and is bolted to a flange 7a on a shaft 7. The plates 8 have axially-extending seatings 10 for the roots of the blades 11. In a modification the side plates extend outwardly of and across the ends of the laminµ and the seatings are formed only in the extensions of the side plates. Alternatively, only the central laminae are in contact over their whole extent and the outer laminµ are spaced outwardly at the hub by spacer rings. The laminµ may be formed by rolling sheet metal discs between conical rolls set with a tapered gap between them and the contacting surfaces are ground except in the region of the grooves 3. Alternatively, the rolls may be formed so that the hub and rim regions of the discs are left thicker to allow for subsequent machining of the grooves.
