Abstract
1473417 Turbomachine blades ROLLS ROYCE (1971) Ltd 23 July 1975 [27 July 1974] 33282/74 Heading F1T A blade, e.g. for a fan or compressor rotor of a gas turbine engine, comprises a single cantilever aerofoil having radially inner and outer aerofoil portions 11, 12 connected by chordwise extending hinge means 13. As shown the latter comprises interdigitated lugs 16, 17 and a pin 14, confronting flat faces, 18, 19, Fig. 3 (not shown), on the lugs acting as stops to limit the extent of pivotal movement. Friction between the pin and lugs damps vibration. Portions 11, 12 may be respectively of titanium alloy and aluminium alloy. In a modification, Figs. 4, 5 (not shown), the hinge means is formed by a weakened neck (21) between the portions 11, 12.
