A method of making a turbine or compressor blade with longitudinal cooling passages, comprises providing a billet 1, Fig. 1, of rectangular cross-section, which tapers over at least part of its length, making longitudinal holes 2 of uniform cross-section in the tapering part, filling the holes with a removable filler, deforming the tapering part by hot working to provide a billet of uniform cross-section whereby the holes become tapered, Fig. 3 (not shown), extruding the part with the tapered holes through a die of approximately aerofoil profile to provide a blade portion 4, Fig. 4, with tapered holes 2B, and finally removing the filler. The holes may alternatively reduce in size from root to tip, Fig. 20 (not shown). Starting holes may be drilled wholly or partly through the billet and in the latter case the billet may be subsequently extruded with the holes leading so that the blind end forms the root 5, or with the blind end leading, whereby this blind end may be later upset to provide a shroud; if the whole billet is extruded the blind end is subsequently upset to form the root. The extruded blade portion may be subsequently machined, Fig. 5 (not shown), whereby the holes remain unaltered or it may be rolled to its final shape, whereby the blade portion becomes tapered towards the tip, Fig. 6 (not shown), and the holes attain substantially uniform cross-section. The root 5 is machined to fir-tree form and, if necessary, connecting-holes are drilled through the root. The starting billet may have its holes drilled parallel with the tapered sides, Fig. 8 (not shown), or only two opposite sides of the billet may be tapered, Figs. 13, 17 (not shown). The Provisional Specification also describes a billet of frusto-conical shape.
