Scanning Infrared Viewer for Turbine Engine Internal Surfaces

A scanning infrared viewing system is proposed for mapping the radiation emitted by the internal surfaces of turbine engines. The viewing system will consist of a rotating, traversing probe housing that will be inserted in the exhaust nozzle of the engine during tests conducted in AEDC test cells. The viewing system will provide point-to-point mapping of emitted radiation which will then undergo image processing to produce the final image. During the Phase I effort, the feasibility of the proposed approach will be demonstrated both analytically and through a bench top demonstration. Final design, fabrication, and testing of the full-scale development system will be conducted during Phase II of the program.
