A New Method of Predicting Land-Based Ski-Jump Takeoff Performance for Fixed-Wing Aircraft

Based on the takeoff safety criterion,a ski-jump model was developed to predict a land-based ski-jump takeoff performance for a fixed-wing aircraft.It was to predict the minimum launch speed and the minimum ground roll.The model is fairly simple,but including the key parameters which effect the ski-jump takeoff performance greatly.The predicted results were compared with the flight test results,it showed good agreement between them.The key parameters were also discussed,so as to demonstrate how to use this new method.The model and the method listed are practical for establishing a land-based ski-jump testing scheme of fixed-wing aircraft.
