METHOD AND SYSTEM FOR INSPECTING BLADE TIP CLEARANCE

摘要

PURPOSE: A blade tip clearance inspecting system and a device thereof are provided to minimize the variability at the blade tip clearance measurement by supplying an automatic and reiterate inspecting method. CONSTITUTION: A blade tip clearance inspecting system comprises an inspection device and a control unit(334). The check system inspects a blade between a rotary blade(204) and a case(212). The inspection device comprises a probe(304) in order to insert within an opening(220) formed within the case. The probe detects the electromagnetic energy reflected to the blade from one or more blade tip unit. The control unit is combined in order to communicate with probe.
