DOWNLOAD EBOOKExperimental verification of the analysis was obtained by using an air-interrupter disk and comparing the vibration amplitudes of turbine blades in a turbojet engine when two different nozzle vane configurations were used. One was an equally spaced vane configuration, and the other was one which the analysis had indicated would result in a reduction of the excitation level. The measured amplitudes of vibration of the turbine blades during engine operation compared favorably with those predicted by the analysis.
