 F-22 Raptor 3999 Completes
Design Limit Load Testing
After more than four months of intense stress, F-22 Raptor 3999 successfully completed 100 percent design limit load testing last October — ahead of schedule. The tests, performed at LM Aero–Marietta, simulated a hammershock condition.
This test was the last one of eighteen design limit test cases to be performed on 3999 since testing began in late May of 1999. Raptor 3999 is a static test article used to verify and certify the F-22’s structural design integrity; the analyses is used to establish the aircraft’s structural capabilities. |
