Abstract

1458734 Making turbine blades GENERAL ELECTRIC CO 19 April 1974 [27 April 1973] 17291/74 Heading B3A A method of making a hollow turbo-machine blade comprises providing a hollow aerofoil blade with a flared open tip 46, placing a tip cap 60 within the flared open end and crimping the open end inwardly to secure the tip cap to provide a blade having a smooth aerofoil outer contour over its length. The interior walls of the blade are formed with seats 52, 54 and a plurality of rabbets 56, 58 for locating and securing the tip cap 60. The cap is formed with holes 68 around its perimeter to direct cooling fluid against the blade walls in the region of the rabbets. The tip cap may be brazed when in position for improved sealing.
