DEVICE AND METHOD FOR MEASURING BLADE TIP PASSAGE TIMES IN A TURBOMACHINE

摘要

A device and method to measure times of passage of blade tips in a turbine engine by a capacitive sensor mounted on a casing in register with a path followed by the tips of blades of a compressor wheel of the turbine engine. The sensor includes at least one elongate electrode fastened to an inside face of the casing and oriented obliquely relative to the path of the blade tips.
