Abstract: 728,670. Turbines and compressors. ROLLSROYCE, Ltd. June 30, 1953 [July 11, 1952], No. 17625/52. Addition to 695,724. Classes 110 (1) and 110 (3). In a turbine or compressor, for example of a gas turbine engine, the casing comprises a pair of concentric shells spaced apart radially, radially-aligned slots being formed in the shells through which an end of each blade is passed, the blade being retained in position by means of a radially-facing shoulder which abuts one surface of one of the shells and by mechanical abutment means which co-operate with the blade and with an oppositely-facing surface of a shell. The casing of an axial-flow compressor shown in Fig. 1 comprises an outer wall 10 and an inner sheet-metal shell 11, which constitutes the outer surface of the working-fluid passage, and a second shell 12 disposed therebetween. Radially-aligned slots are formed in the shells 11, 12 and the ends of the blades 13 which are formed with shoulders 13a are passed therethrough. The lugs or tangs 14 formed at the ends of the blades by the inclined slots 14a are then bent to engage the shell 12. The shoulders 13a may engage either the inner shell 11 or the outer shell 12, and the tangs may alternatively be formed by slotting at the centre of the radially outer end of the blade. In Fig. 4 the ends of the blades are formed with notches 15 which are engaged by a locking member 16 retained in position by a spacer strip 17 tackwelded at 18 to the shell 12. The strip 17 serves to retain the locking members 16 of two adjacent rows of blades. In a further embodiment, the radially-outer ends of the blades are formed with closed slots which lie radially outwardly of the outer shell 12, a locking strip or wire being threaded through the slots. The radially-inner ends of the blades may carry flanged sheet metal members to provide seals with adjacent rotor structure, the members being threaded over the blades and secured to retaining strips engaging notches in the blades.
