T-38 missions at speeds above the existing crew enclosure damage threshold will result in flight safety risk to aircraft and crew. This paper summarizes the design/development of alternate T-38 transparencies having the capability of defeating the impact of a four pound bird at aircraft speeds up to 400 knots. A preliminary design and evaluation defined the guidelines and constraints governing the modifications, defined and assessed candidate transparency configurations, and conducted a birdstrike risk assessment. Edge attachment screening tests were conducted fracture mechanism, and energy absorption potential. A parametric finite element analysis examined the effects of transparency and support structure stiffness versus peak load and deflection. A full-scale flight hardware test program established the failure threshold for the existing T-38 forward windshield and forward canopy for a four pound birdstrike at six impact locations.
