This report covers the work under Task C of Contract F33615-83-C-3208. An SPF based A-10 nose landing gear door was designed using Supral 220 alloy: The part count for the basic door was reduced to 4 components as compared to 52 for the conventional construction method. The superplastic pan comprising the stiffening structure of the door was assembled to the external skin using the ultrasonic weldbonding process. The SPF based door and conventional door were supplied to AFFDL for static testing. Test results show that the two doors are approximately equivalent in strength. Economic analysis indicates that the SPF door is less than half the cost of the conventional door for production quantities larger than 100. Keywords: Aircraft panels; Aircraft doors; Superplastic forming; A -10 nose landing gear door supral-220, Ultrasonic welding. (kt)
