METHOD TO FIXTURE AND INSPECTION CONTOURED AERODYNAMIC SURFACES

摘要

A method to fixture and inspect contoured aerodynamic surfaces of a part, such as an engine inlet lip skin, is provided. A controlled preload is applied to one or more discrete locations along the contoured surface to constrain the lip skin at the locations the lip skin would be constrained upon assembly on the airplane. The contoured surfaces are then inspected to dimensional requirements. The controlled preload can be applied by use of magnets or elastic bumpers.

1. A method comprising:
providing a part having a contoured surface; applying a controlled preload to one or more discrete locations along the contoured surface to constrain the contoured surface, the discrete locations corresponding to points of attachment on the part when assembled with another component to form a final assembly; and inspecting said contoured surface to dimensional requirements.
