Proof test all flight units to 1.1 times limit 3. Protoflight test one flight unit of a fleet to 1.25 times limit 4. No structural test 1.1 1.1 1.25 1.6 1.25 1.25 1.4 2.0 Several tests other than static tests also verify strength; the best test The test objective was to identify methods to reduce the nozzle flap loads on both axisymmetric and nonaxisymmetric nozzles. Several methods were discovered to reduce nozzle turkey feather loads but the USAF decided that the simplest "fix" was to just remove the nozzle fairings as shown the last photograph of an actual flight article.
