APPARATUS AND METHOD FOR NON-DESTRUCTIVE DETECTION OF FAN BLADE ELECTRICAL ISOLATION

APPARATUS AND METHOD FOR NON-DESTRUCTIVE DETECTION OF FAN BLADE ELECTRICAL ISOLATION

An apparatus and method for detecting a short in a blade (70) of a gas turbine engine, the apparatus including: a first plate (92) configured to form a first capacitor (C 1 ) with the protective sheath (80) when the apparatus is located proximate to the blade (70); a second plate (94) configured to...
