COMPRESSOR NOISE RESEARCH.
Abstract
The noise generating mechanisms of axial flow compressor blades were investigated using flat blades to facilitate mathematical analysis. Analytical expressions are given for evaluating the compressor noise due to blade thickness, loading and vortex shedding. Measured values of compressor noise show good agreement with those analytically predicted. It was found that lift or loading noise dominates over blade thickness and vortex noise. Rotor-stator spacing and clearance between the rotor blade tips and the duct are important parameters in the generation of rotor noise. (Author)
