Application of the discrete-phase method /DPM/ to the investigation and monitoring of aircraft turbine engine blade vibrations. II
Abstract
Part I dealt with the ELIA-2 device and its application to the determination of dynamic stresses in spinning blades by measuring the amplitudes of blade tip vibrations. In the present paper, the electromagnetic and capacitance sensors employed in this device are discussed, and a method for calibrating the ELIA-2 device is proposed. The application of the discrete-phase method to the determination of blade resonance vibrations, blade flutter, and blade buffeting is described.
