Orthogonal Experimental Optimization Design for Improving Aerodynamic Characteristics of Hovering Air Vehicle

Abstract

Abstract: Vertical hovering MAV model with flexible aerodynamic shape was proposed. The passive adaptive deformation that produced on the aerodynamic shape was designed to absorb disturbance from outside airflow pressure, and furthermore to improve aircraft's disturbance resistance ability. Multiple factors' effects for aircraft's aerodynamic characteristics were analyzed, such as structural geometrical parameters, candidate material properties, and environmental parameters. The orthogonal experimental analysis of aircraft aerodynamic forces was accomplished, which include the forces produced in the horizontal and vertical direction. The significant factors effecting on the flight performance were discussed and the best response value in the selected parameter range was found out. Optimum combination of design parameters was optimized. The results show that under the gust the disturbance resistance ability of designed model can be improved through parameters optimization, and aerodynamic characteristics can be produced to realize smooth flight and enhance aircraft's disturbance resistance ability.
