B -- C-2A(R) OUTER WING PANEL FATIGUE TEST POC Contact Donna Guenther, AIR-2.5.3.4, (301) 342-3937/Contracting Officer, Robert L. Hults, (301) 342-3937. The objective of this synopsis is to seek interested sources with the capability and expertise to perform a full scale fatigue test of the C-2A(R) Outer Wing Panel with flight, ground and thermal compressive loads applied utilizing a Navy supplied Outer Wing Panel. The outer wing panels experience compressive strains due to the temperature gradients induced by the impingement of engine exhaust on the lower surface with wings in the folded position. The thermal compressive strains would be applied by duplicating the actual isotherms and strain measurements. Test flight and ground conditions as well as isotherms and thermal strain measurements will be provided by the Navy. The task will include test setup, conducting the test, data measurement, periodic non-destructive testing inspection, recording, reporting and partial disassembly of the outer wing panel with metallurgical evaluation of approximately 10,000 hole layers of the test article to inspect for anomalies. Testing of 20,000 equivalent flight hours is required and testing to 30,000 equivalent flight hours is desired. The effort requires the ability to enhance and repair the outer wing panel in order to meet its target fatigue life. (0029)
