Abstract

621,315. Elastic-fluid turbines and compressors. MORLEY, F. W. W. Feb. 17, 1947, No. 4588. [Class 110(iii)] Axial flow turbine or compressor blades 21 are secured to the rotor by pivoted joints. The joint pin 27 has a small clearance in the holes in the lugs 23 on the blade and the lugs 24 on the rotor. These blades are used in those cases where rigidly mounted blades would have a natural vibration frequency equal to that of a periodic excitation at an operational speed of the rotor.
