Abstract

L'invention concerne un procédé et un appareil pour inspecter des composants intérieurs d'un moteur turbine à gaz sans avoir besoin de désassembler le moteur. L'idée centrale de l'invention consiste à fixer l'extrémité d'observation d'un appareil d'inspection à fibres optiques à une ou plusieurs ailettes du rotor du moteur et de déplacer l'extrémité d'observation en direction circonférentielle en tournant le rotor. L'invention est particulièrement utile pour inspecter les aubes de stator.A method and apparatus for inspecting interior components of a gas turbine engine without the need to disassemble the engine is disclosed. The central idea of the invention is to attach the viewing end of a fiber optic inspection apparatus to one or more vanes of the rotor of the motor and to move the viewing end circumferentially by turning. the rotor. The invention is particularly useful for inspecting stator vanes.
