Abstract
716,105. Turbine blades. STALKER, E. A. May 24, 1950, No. 13018/50. Class 110(3) [Also in Group XXII] A turbine blade has a plurality of slots 20 formed in the leading edge through which a cooling fluid can flow from the hollow interior of the blade, the slots having their ends on either side of the leading edge inclined towards one and the same end of the blade and leading into the concave and convex surfaces of the blade. The slots on either side of the leading edge may be continuous to form slots of crescent or chevron shape. The blade may be formed from a metal blank 40 having a thickened part 42 in which crescentshaped slots 20 are formed, the blank then being folded about the thickened part to form a hollow aerofoil section, the thickened part forming the leading edge thereof. Alternatively, slots 84 may be cut in the thickened leading edge portion of an aerofoil section blank by means of a conicalshaped hollow saw as shown in Fig. 7. The blade is inserted in a root portion 14 and welded thereto. Specifications 652,870, 679,467 and 716,144, are referred to.
