Thermal Defects of Avionic Turbojet Engines
Research Works of Air Force Institute of Technology, 2016 AbstractThe paper analyzes the most frequent reasons associated with operation of avionic turbojet engines (ATE) and leading to initiation of thermal defects affecting turbine units. These reasons are illustrated with examples of gradual deteriorations revealed on surfaces of turbine parts and subassemblies and defected during endoscopic examinations ...
