An experimental test facility has been developed for performing realistic simulation of flight loads on sections of aircraft wing structures. Concurrently, an analytical technique was developed for predicting the internal load distributions of ballistically damaged, multiple load path aircraft wing structures. In all, six replica wing structures and one T-38 wing structure were tested in the loads facility. The analytically predicted stresses were satisfactory, especially when the response was in the linear range. However, with a substantial amount of damage present and/or when the response was nonlinear, the experimental and analytical results differed substantially. This is thought to be caused by oversimplified finite element models. Further testing is forthcoming. (Author)
