Abstract

751,951. Turbine blades. GASTURBINE MAATSCHAPPIJ N.V. Jan. 24, 1951 [Jan. 24, 1950; Dec. 12, 1950], No. 1863/51. Class 110(3) [Also in Groups XXII and XXIII] A turbine rotor blade varies in camber and thickness along its length and is of twisted form. It is provided with a grooved root portion 2 and a head portion 3. The head is provided for securely gripping the blade during machining (see Group XXII) and may be removed subsequently.
