Abstract

599,391. Turbine and like blades. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and BAXTER, A. D. May 25, 1945, No. 13198. [Class 110 (iii)] A drum casing or rotor of a turbine or axial flow compressor is formed with rings of holes 18 each hole being adapted to receive the root 14 of a blade and being provided with a seating for a flange 17 on the root. The blades of a ring are secured in place by a strap 16 which may be received in a recess in the drum. The seating may be flat or concave and may be formed with a recess to receive a sealing - washer 15. The holes 18 may be non-circular with their greatest dimension corresponds approximately to the blade chord. In the case of inwardly projecting blades the strap may have any suitable tightening means and with either inwardly or outwardly projecting blades the strap may be a ring sprung into position. The casing or drum may be covered by wire wound under tension upon it.
