Alternate T-38 Transparency Development. Part 4. Parametric Studies.

Abstract

Studies conducted to examine the effect of structural parameter variations on the nonlinear, dynamic response of the T-38 student windshield/support structure system to bird impact are described. The studies were conducted using the materially and geometrically nonlinear analysis (MAGNA) finite element computer program. Both static and transient dynamic analyses were conducted, examining the effects of changes to the transparency and support structure stiffness, intensity of the applied load both coupled and uncoupled, and duration of the impact event. Significant results of the finite element analysis include transparency deflection, peak load versus transparency stiffness, and resultant force plots both along the aft arch and around the impact area. A discussion of application of the finite element method to the birdstrike problem is also presented. (Author)
