EVALUATION OF HIGH-TEMPERATURE CAST-IN-PLACE TRANSPARENT PLASTIC LAMINATES SUITABLE FOR CANOPIES ON SUPERSONIC FIGHTER AIRCRAFT
GOODYEAR AEROSPACE CORP AKRON OHIO
Pagination or Media Count:
Wind tunnel tests conducted at Mach 2.75 conditions on as cast Plex 55 indicated that no rippling or flow of the surface will occur in a high-speed air stream. Flexural and tensile properties were obtained for the epoxy thermal barrier material. Operational temperature cycle testing at Test C conditions was continued. Several premature specimen failures were experienced, but the test specimen configuration was redesigned to eliminate this tendency to failure, and new test specimens are now ready for testing. No forming or laminating attempts were made during this period on either the canopy or windshield side panel. The no. 1 side panel casting indicated that a different type of forming mold would be required for this port on of the program. The new mold has been fabricated and is nearly ready for use. Author
