Abstract

1,107,024. Turbine and compressor blades. C.A. PARSONS & CO. Ltd. Nov. 4, 1966 [Nov. 4, 1965], No.46882/65. Heading F1T. A turbine, compressor or fan blade 1 is fitted at its free end with a sleeve 4 having an external profile similar to that of the blade, the sleeve being joined to, and projecting beyond, the end of the blade. The internal profile of the sleeve may also be similar to the profile of the blade, as shown, or the sleeve may fit over a projection at the blade end. The sleeve reduces working fluid leakage past the blade tip and may be used to repair a worn blade.
