Abstract

1285369 Turbomachine blades ROLLS ROYCE Ltd 14 Dec 1970 [16 Dec 1969] 61365/69 Heading FIT A hollow turbomachine blade, e. g. for the turbine of a gas turbine engine, has a plate 34 recessed into the concave and/or convex blade surfaces, channels 36 being provided between the plate and blade wall and communicating with apertures 32, 38 in the wall and plate to provide a flow path for cooling air from the interior to the exterior of the blade. The channels 36 are formed on the inside surface of plate 34 or the outside surface of the blade wall and each has an X, L, T, swastika or other shape. The cooling air is supplied to the interior of the blade through apertures 42 and some exhausts through holes 40 in shroud 26 and some through apertures in the leading and trailing edges of the blade.
