ABSTRACT:
A turbine compressor clearance indicator device is used to measure the clearance between a rotor blade and a case and/or between a stator vane and a rotor shaft. The device has a dial indicator mounted in a "U" shaped holder having two feet. Each foot has two surfaces, one concave and one convex, for use on two different curved surfaces. The thicknesses of wax strips are measured once they are cut away by the tips of the blades and vanes.
