Abstract:

Very little experimental data exists on the landing impact loads encountered during landings of VSTOL airplanes. Development of criteria for predicting these loads has been initiated with the collection of data on the X-22A flight research program. Special instrumentation has been installed in the X-22A to measure sink rate data during landing approaches. The instrumentation was calibrated before and during the flight tests. Data was obtained for 31 landings, and statistical analyses were performed. Because of the small number of landings involved in this program, a firm statistical data base cannot be obtained, but certain trends are apparent. Histograms of the pertinent parameters are presented to show these trends, and tables of data obtained for each flight are included. Author
