DEVELOPMENT OF RESPONSE SURFACE MODEL OF ENDURANCE TIME AND STRUCTURAL PARAMETER OPTIMIZATION FOR A TAILSITTER UAV

Development of Response Surface Model of Endurance Time and Structural Parameter Optimization for a Tailsitter UAV

This study designed a vertical take-off and landing tailsitter unmanned aerial vehicle (UAV) with a long endurance time.Nine parameters of the tailsitter UAV were investigated.Using a 2k full factorial test, 512 experiments on the nine parameters were conducted at their maximum and minimum values.The time coefficient and air resistance were calcula
