Abstract

965,169. Compressor blades; axial flow compressors. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Jan. 23, 1963 [Feb. 14, 1962], No. 5733/62. Headings F1C and F1T. An aerofoil blade for a fluid flow machine such as an axial flow compressor has a root pivoted in a support structure and two screwed members engaging in tapped bores in the structure and abutting against the root such that each screwed member imparts to the root a turning moment about the pivotal axis opposite to that of the other screwed member so as to adjust the stagger angle of .the blade. A compressor inlet guide blade having a circular root 2 is retained in a bore 4 of an annular flanged ring 5 within the compressor casing 10 by a circlip 8 and shoulder 6 on the aerofoil portion 1. Two screws 11 abut against a surface 12 at the bottom of a slot 3 in the root 2 and may be adjusted to alter the stagger angle of the blade.
