F-16 Reverse Engineering & Fit Prediction

Customer Lockheed Martin - Tactical Aircraft Systems (TAS)
Location Fort Worth, Texas
Task Perform Join Prediction of Mating F-16 Fuselage Sections and Reverse Engineer Gage Based Surfaces to CAD Models

ATT Metrology was contracted to measure the forward and center fuselage mate areas on an F-16 Fighter Jet prior to joining the aircraft in the factory. ATT used the laser tracker data to develop NURBS surfaces using a reverse engineering software package. This same package was used to perform the “virtual fit” in the CAD environment to determine interference areas. The project validated the join prediction techniques and is slated to be incorporated into the next generation F-22 and JSF fighter programs.
