  • Patent number: 7412780
    Abstract: A template for assessing damaged areas on an object, such as a fan blade or other item, includes a set of marks indicating the maximum areas of damage allowed on the periphery of the object. A guide enables the template to be aligned in proper position against the object for accurate visual inspection of the damaged areas. For example, one or more blend guides are included to allow the inspector to mark a blend area around the damage to enable maintenance personnel to smooth sharp, jagged edges of the damaged areas, thereby relieving stress points and improving the aerodynamic efficiency of a blade in an engine. The template can include a magnifying portion that allows the user to see more detail on the object. Linear and/or curved measurement scales can also be included on the template.

  • Patent number: 6910278
    Abstract: A template for assessing damaged areas on a blade includes a set of marks indicating the maximum areas of damage allowed on an edge, as well as the tip of a blade. A guide enables the template to be aligned in proper position against the blade for accurate visual inspection of the damaged areas. One or more blend guides are included to allow the inspector to mark a blend area around the damage to enable maintenance personnel to smooth sharp, jagged edges of the damaged areas, thereby relieving stress points on the blade and improving the aerodynamic efficiency of the blade. The template is fabricated with transparent material that allows the blade to be viewed when the template is overlayed on the blade. A mechanism such as a clip, a sleeve, or magnetic attraction can be included on the template to retain the template on the blade during inspection.
