Abstract
Apparatus and associated methods relate to autonomous devices configured to inspect surface topologies of airfoils of a gas turbine engine. The autonomous device moves across the airfoil while remaining coupled thereto while sensing the surface topology of the airfoil using a plurality of topological sensors. Each of the plurality of topological sensors includes a piezoelectric sensor that generates an electrical signal indicative of a loading to the piezoelectric sensor, as well as an airfoil contacting member. The airfoil contacting member extends between the piezoelectric sensor and the airfoil when the body is coupled thereto. The airfoil contacting member provides changes to the loading to the piezoelectric sensor in response to changes in the surface topology of the airfoil as the body moves thereacross.
