Abstract : A study was performed to plan the effort required by commercial transport manufacturers to accomplish the transition from current construction materials and practices to extensive use of composites in wings of aircraft that enter service in the 1990 time-period. The engineering and manufacturing disciplines which normally participate in the design, development and production of a new aircraft were employed to ensure that all of the factors that would enter a Company decision to commit to production of a composite wing structure were addressed. A conceptual design of an advanced technology reduced energy aircraft provided the framework for identifying and investigating unique design aspects. A plan development effort defined the essential technology needs and formulated approaches for effecting the required wing development. Presented are two separate programs: (1) a j6int government-industry material development program, and (2) a task-oriented wing structure development program. This report presents the wing development program plans, resource needs and the supporting data for the development plans. (MM)
