Abstract
1359896 Turbine blades ROLLS-ROYCE (1971) Ltd 16 April 1973 [19 Jan 1972] 2678/72 Heading FIT [Also in Division B5] A method of making a bladed member e.g. a nozzle guide vane 2 for a gas turbine engine see Fig. 1 (not shown) comprises hot pressing a first mixture of silicon nitride powder and a fluxing agent e. g. magnesium oxide in a first mould to form an aerofoil portion 4, placing the formed aerofoil portion in a split die 24 so that at least one end protrudes therefrom, placing the die 24 in a second split die 16 of a second mould 10, placing a second mixture of silicon nitride powder and fluxing agent in a shaped portion of the second die 16 so that the end of the aerofoil portion 4 extends therein to and hot pressing the second mixture to form a shroud portion which is amalgamated with the aerofoil portion. As shown, both ends of the aerofoil portion 4 extend into a respective shaped portion of the die 16 so that inner and outer shroud portions 6, 8 may be formed. The aerofoil portion 4 is initially located on a positioning plunger (18), Fig. 2 (not shown) within the die 16 so that the mixture for the inner root shroud portion 6 may be introduced. The mould 10 is then turned over, the positioning plunger (18) removed, and the mixture for the outer shroud portion 8 added. The plungers 22, 20 for hot pressing the inner and outer shroud portions 6, 8 may have plain faces or faces shaped to produce fixing means such as flanges, webs, apertures and dowels in the completed member. The plungers 20, 22 may also have preformed shroud parts (30, 32) Fig. 3 (not shown) attached thereto prior to pressing so that upon pressing at a pressure of about 1200 p. s. i. and a temperature of about 1750C the preformed shroud parts become amalgamated with the shroud portions 6, 8. The preformed shroud parts (30, 32) may be provided with the above fixing means. The mixture for the shroud portions 6, 8 may be lightly compacted at normal temperature prior to pressing. The mould 10 also includes a susceptor 12 supported on a packing ring (14), Fig. 2 (not shown).
