Abstract

813,522. Gas turbine engine bladed rotors. MACKAY, J. D. A. May 16, 1957 [May 18, 1956], No. 15595/57. Class 110 (3). A bladed rotor assembly for a gas turbine engine comprises a rotor disc 10 having a screwed cylindrical surface and a blade-carrying ring 12 having a complementary screwed surface which engages the screwed surface of the rotor disc. The blade-carrying ring has slots 14 extending therethrough in which the radiallyprojecting rotor blades 15 are mounted, the rotor disc in the assembly closing the slots in the blade-carrying ring so as to secure the blades against inward radial movement. Means are provided to cause rotation of the two parts relatively to each other for assembly or dismantling. The holes 14 in the blade-carrying ring 12 taper radially outwardly and the blade roots 15a are correspondingly shaped whereby radially outward displacement of the blades 15 is prevented. A circumferential groove 17 is formed in the cylindrical surface of the rotor disc, cooling air being supplied to the groove through openings 18 in the ring 12, the air finally discharging through longitudinal passages in the blades. The blades may be held temporarily in the ring 12 during assembly or dismantling by means of a resilient ring member 19 which is engaged within the ring 12 so as to bear against the blade roots. The ring 12 in Fig. 1 is formed with slots 21 which may be engaged by lugs 20a of the ring tool 20. In Fig. 2, the ring 12 is formed with gear teeth 23 which may be engaged by the pinion 25, rotation of the handle 27 thus enabling the ring 12 to be screwed on to or off the rotor disc 10.
