In situ combustion turbine engine airfoil inspection

摘要: A system ( 10 ) for imaging a combustion turbine engine airfoil includes camera 12 and positioner 24 ). The may be controlled to dispose the within an inner casing of at first position acquiring image. then moved second storage device 30 stores images, processor 32 accesses generate composite image from images. For use when is rotating, also include sensor 40 generating signal 41 responsive detected angular airfoil. further trigger 42 ), signal, triggering acquire proximate camera.
