Reference number : GC-2017-Q4-00251, amendment number : , agreement type : G, recipient legal name : Bridges, Greg (University of Manitoba)|Bridges, Greg (Université du Manitoba), recipient country : CA, recipient province : nan, recipient city : Manitoba, recipient postal code : nan, program name english : Engage Plus Grants for universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : In jet engine design knowledge of the clearance between an airfoil blade tip and engine housing is an important_x000D_
factor that can dramatically affect engine performance. This gap can change due to extreme temperature_x000D_
variations and high centrifugal and torsional forces. GE Aviation has developed a sensor to monitor airfoil_x000D_
clearance. The sensor is mounted in the engine housing and is based on sensing the capacitance change as the_x000D_
blade passes over a probe. The probe is coupled to a cavity and resonator based electronics, which produces an_x000D_
output signal. Accurate measurement of the clearance requires modeling and calibration of the sensor. GE_x000D_
Aviation will be partnering with Dr. G.E. Bridges at the University of Manitoba to develop a multi-physics_x000D_
model for determining the capacitance change measured by the clearance probe and use this to calibrate the_x000D_
sensor output signal. In Phase I a model of the probe tip-blade for different geometries and materials was_x000D_
developed. In Phase II, the coupled cavity and electronics will be modeled. The model will be based on_x000D_
electromagnetic simulation. Experimental verification will be performed using a bench-top spin-rig system,_x000D_
built by GE Aviation for testing their clearance sensor. A PhD student from the University of Manitoba with_x000D_
expertise in computational electromagnetics will develop and verify the calibration model. In addition to_x000D_
providing details of the clearance sensor, GE Aviation will provide a bench-top spin-rig system and aid in_x000D_
obtaining measured results. GE Aviation is one of the worlds top suppliers of aircraft engines and offers_x000D_
engines for military and commercial aircraft. The calibration model developed in this project will provide an_x000D_
important component for the accurate use of GE Aviation's clearance probe, subsequently aiding in improved_x000D_
design and performance of their jet engines., program purpose french : In jet engine design knowledge of the clearance between an airfoil blade tip and engine housing is an important_x000D_
