Abstract

In a bladed rotor assembly, compressor blades 16 have roots 16a which straddle the rim of rotor disc 14. Disc 14 has local projections 18 and the blade roots have feet 20. A ring 22 fits over the blade feet 20 and under disc projections 18 whereby the blades are secured on the rotor disc. <IMAGE>
