AFWAL Flight Dynamics Laboratory, Structures and Dynamics Division, McDonnell Aircraft Company MCAIR is developing concepts and procedures for the rapid repair of battle-damaged composite structures. The damage consists of elongated or concentrated penetrations of solid wing skins and of honeycomb empennage. The size of the damage, in conjunction with the strength-critical nature of these structures, requires structural repairs in order to restore a strength capability commensurate with the maximum expected flight loads and service temperatures. Guidelines for these repairs are based on the USAF concept of operation for aircraft battle damage repair. Structural tests are being conducted to validate repair designs. Damage simulation, repair, design, damage cleanup, repair fabrication, and available test results are reported in this paper.
