Abstract : This paper provides a review of the T-38 arch reinforcement as it relates to the T-38 Birdproofing Program. Due to the increase in low level training missions in the T-38 aircraft, there exists a need for an improved transparency system capable of withstanding a four (4) pound bird impact at 400 knots. The existing student windshield frame is made of cast magnesium alloy (AS9LC-T6) and is neither strong enough nor stiff enough to support a windshield or canopy during the bird resistant transparency system for the T-38. As a result, three methods of reinforcing the frame are under consideration: (1) a three piece metal casting, (2) a continuous composite, (3) a continuous machined or stretched formed high strength metal reinforcement.
