Abstract

1315879 Turbine blades CURTISS-WRIGHT CORP 13 July 1971 [27 July 1970] 32797/ 71 Heading FIT A gas turbine rotor blade comprises a solid strut 12 integral with root tip and platform portions 13, 14, 22 and having spanwise and chordwise lands 16, 17 defining chambers 18 to which cooling air is supplied through bores 24 in platform 13 the air escaping from chambers 18 through the pores of an overlying sheath 21. The latter may be formed by a sintering process using powdered metal or ceramic, or layers of wound or woven mesh and is welded or brazed to the bands 16, 17. Radially adjacent chambers 18 interconnect via ports 26, 27 in lands 17 ports 27 being of reduced flow area to ensure correct distribution of cooling air. Ports 28 may be provided in lands 16. Bores 24 are either radial or angled (as at 24a, Fig.7 (not shown)) to supply air from one side of root 22 to chambers 18 on the opposite side of the blade.
