SUMMARY OF RESULTS FOR A TWIN-ENGINE, LOW-WING AIRPLANE SUBSTRUCTURE CRASH IMPACT CONDITION ANALYZED WITH PROGRAM "KRASH"

This report contains the results of using digital computer program KRASH to model and analyze the dynamic response of a twin-engine, low-wing airplane substructure subjected to a 27.5 ft/sec vertical velocity impact. The test was performed previously by NASA-Langley as part of a joint FAA-NASA effort concerning general aviation airplane crash dynamics. Included in this report are the math model description, pertinent test data, a comparison of analysis versus test results and the results of a limited parameter sensitivity study using program KRASH. Floor and occupant pelvis vertical acceleration responses obtained from test measurement are compared to corresponding analytical results. The effect of model representation and input data selection variations on dynamic behavior are evaluated. Conclusions are presented based on the results of the effort. (Author)
