Abstract

721,049. Turbine and compressor blades. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Dec. 4, 1952 [Dec. 10, 1951], No. 28936/51. Class 110 (3). In an elastic fluid turbine or compressor, a rotor or stator blade and vibration damping means therefor comprises a hollow blade secured to the rotor or stator body, in combination with a leaf - spring secured at one end to the rotor or stator body and extending through the blade and bearing resiliently against the internal wall thereof. In the embodiment shown, the flanges 1a of the hollow sheet metal rotor blade 1 are secured to the flange 2a on a rotor disc by means of rivets 3. The leaf - spring 4 comprises two limbs and is also secured at the root end to the flange 2a by means of the rivets 3. Specification 719,079 is referred to.
