N2 - Several researchers have considered non-contact methods to monitor blade vibration such as the blade tip timing method. This method uses contactless sensors mounted on the casing around the engine. Eddy current sensors are investigated in this work due to their efficacy for monitoring blade vibration in harsh environments compared to other type of sensors. Very little experience in the modelling of eddy current sensors is available in the literature; therefore, a detailed 3D finite element model to simulate a rotating bladed disk passing an eddy current sensor was performed. In addition, a laboratory scale test rig was designed and manufactured in order to validate the proposed model with experimental measurements. Numerical and experimental results are presented in this paper. The integrated measured output of the sensor was investigated to show the effect of the blade deformation and clearance on the accuracy of the Blade Tip Timing measurements. Finally, a demonstration of blade vibration based on measurements was performed.
