Innovative automated positioning and inspection techniques were developed for the inspection of the U.S. Army’s T700 engine components. Because of the size of the T700 engine, some of the geometries were challenging for inspection development. This paper extends the development work performed for the U.S. Air Force engine components and describes the progress of the development for a small critical feature in the Army’s T700 turbine engine components. A probe was developed and several attempts of using this probe for positioning were made for this small feature. The successful candidate was automated and an innovative inspection technique was also developed. A series of tests were undergone simulating the conditions in production inspection environment: multiple inspections, multiple parts, multiple probes, multiple stations and multiple operators. Preliminary results indicated that the airhole inspection worked well in these conditions and satisfied the inspection requirement using the RFC/NDE station. To meet the inspection challenge, a special reliability setup was developed. Discussion of this setup and the need of a future study are also addressed. © 2000 American Institute of Physics.
