Abstract:

This interim technical report describes the progress made during year 3 of SRI International's Phase II effort to develop a computational capability for designing lightweight fragment barriers for commercial aircraft. Fabrics of high-strength polymers have been shown to be excellent candidates for these barriers. A series of large-scale fragment impact tests was performed at SRI's remote test site to characterize the resistance of full-scale fabric barriers to realistic fragment impact and provide data for model calibration and verification. These tests have demonstrated the importance of allowing material failure to occur near the held comers of a fabric barrier, but not allowing the comer to detach from the fuselage frame. In addition, SRI designed and implemented laboratory tests to characterize the cut resistance of the fabric yams to sharp blades. Results show a strong effect of the slicing angle upon the energy absorbed during yam failure. Simulations using the detailed computational fabric model showed the effectiveness of holding the fabric at the comers. A time efficient, user-friendly design model for fabric barriers is being developed. The model, previously calibrated against small-scale gas gun tests, was used to simulate the large-scale fabric impact tests. The results of the simulations showed that the current model is stiffer and stronger than the measured response of the fabric. In a continuing effort to keep the civil aircraft community informed, SRI hosted the Fourth Federal Aviation Administration Workshop on Uncontained Engine Debris, updated its Aircraft Engine Fragment Barriers web site to include an overview of all work performed to date, and prepared several papers for submission to technical journals and symposia.
