The development of advanced aircraft transparencies which meet USAF 1995-2000 mission requirements is described and illustrated. The key 1995-2000 mission requirements are first identified. A review of available birdstrike test data is then presented. This review demonstrates that the birdstrike requirement can be met with current technology. Based on the review, a set of design guidelines is given for improved bird impact resistance while meeting the additional future requirements. Subscale coupon testing to screen potential laminates for impact resistance and to obtain mechanical properties for use in finite element analysis (FEA) is then given. The mechanical properties of transparency polymeric materials have been found to be sensitive to strain rates, necessitating the tests to ensure accurate results in subsequent FEA. Nonlinear dynamic FEA for final analytic bird impact evaluation is described next. This task utilizes the recently-developed X3D explicit FEA code which provides strain rate-dependent material properties, direct modeling of the bird, element and ply failure criteria, and rapid turnaround on workstation and mainframe computers. Final design selection in view of their ability to meet all design requirements is described. Full scale fabrication and testing are underway, with initial findings presented herein.
