The F-15E aircraft is one of two evolutionary aircraft types which are currently being evaluated by the USAF for future low level, high speed, and attack and interdiction missions. It is a two-place aircraft and is proposed to utilize the windshield/canopy transparency system which has been in production for some years for the TF-15 aircraft. The canopy portion of this transparency system has a high lofted shape and offers considerably more presented frontal area than the canopy for one-place models of the aircraft. As a result of the lofted shape of the TF-15 canopy and the mission of the aircraft, the hazard of transparency bird impact during flight operations is significant. Some proposals to increase the level of bird impact protection for the F-15E canopy have already been aired. The availability of an analysis method which could accurately predict the dynamic structural response of such proposed canopy designs to bird impact loading would be valuable in establishing the merits of each. If the MAGNA nonlinear finite element analysis program could be validated for F-15 transparency analysis it would have significant potential for saving time and costs in the development of improved F-15E transparencies. The goal of MAGNA.
