Abstract

1309646 Turbine blades DEFENCE SECRETARY OF STATE FOR 19 April 1971 [10 April 1970] 17154/70 Heading F1T A gas turbine rotor comprises blades 11, each of which is connected to its nearest neighbours by a curved tie member 13 which is concave towards the rotor axis and which is attached to the blades by threaded extensions 15 fitted with nuts 18 having convexly spherical faces cooperating with concavely spherical faces 17 in the blades. The faces 17 may be formed in bushes sunk in the blade section. Each tie may comprise a cylindrical rod flattened over its centre section to form an aerofoil cross-section. The blades themselves may be made of a fibre reinforced composite material and the points of attachment of the ties to the blades may be staggered to counteract the tendency of centrifugal force to untwist the blades.
