Abstract

903,124. Turbine and compressor blades. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. April 19, 1961 [May 18, 1960], No. 17540/60. Class 110 (3). A blade for an axial-flow turbine or compressor has a free tip end and has its working portion so constructed that its torsional flexural axis lies between the blade leading edge and the lift axis of the blade. A compressor blade has a metal forward part 13 integral with or attached to a root portion 12 and a flexible plastic rear part 14. The torsional flexural axis 16 is effectively that of the forward part 13 and is forward of the centre of lift acting through a lift axis 15. In operation, the blade tip will be at a lower incidence than the root and it can be arranged that unstable flow conditions are avoided or minimised to reduce the risk of flutter. In alternative constructions a central pillar, integral with or attached to the root is surrounded by plastic or like material forming the blade profile or an all metal blade has a chordwise slit 19 extending from the trailing edge (Fig. 7).
