Aerodynamic Damping in Turbomachinery
1972
An experimental study of aerodynamic damping has been carried out on an axial compressor in which stagger angle, pressure ratio, and relative velocity was varied. The study utilized explosive charges buried in the tip of the blade to provide excitation and found the damping by measuring the log decrement of the vibrations. The blade vibratory mode was pure bending.Copyright © 1972 by ASME
