A program was conducted to investigate the technical feasibility and practicality of using dynamic scale modeling techniques to design, fabricate, and test a scale model of an aircraft landing gear strut and tire. Dynamic scaling laws were developed and used to design a one-third model of an A-37 Nose Landing Gear (NLG) strut and tire. The A-37 NLG strut and the model gear were tested under dynamically similar conditions of weight, speed, and forcing function on a circular track, Dynamic Test Machine at the Mobility Development Laboratory, Wright-Patterson AFB OH. Comparison of time history data, recorded during each phase of testing, indicated good correlation of the dynamic response of the model landing gear, in relation to the scaling laws and the A-37 NLG dynamic response. Presented in the report is the development and analytical verification of the scaling laws, test data and comparisons, conclusions, and recommendations.
