Abstract : Accurately predicting in-service durability of aircraft transparencies is beyond the present state-of-the-art. There are, however, approaches to testing and evaluating candidate designs and materials that may provide more useful test results than some of the more commonly used test methods. A testing methodology has been derived that uses a logical combination of exposure conditions and test methods to evaluate the durability of plastic aircraft transparency materials. While most testing naturally involves coupons, durability testing of full scale transparencies is also recommended. A large, complex facility has been constructed which can impose combinations of temperatures, pressure differentials, and exposure conditions that represent both the in-flight and flight line environments. This paper describes the tests and exposures recommended in the methodology, plus describes the preliminary conclusions and lessons learned from using the full scale testing equipment.
