Design and Static-Dynamic Performance Analysis of a Type of Flapping-wing Aircraft
This paper points out that the biomimetic flapping-wing aircraft,with its unique biomimetic principles and outstanding maneuverability,has always been a research hotspot in the field of aircraft.In order to study the coordination between the mechanisms of biomimetic flapping-wing aircraft and improve the stability of the aircraft,based on the traditional crank-rocker mechanism,this paper studies and develops a bird-like flapping-wing aircraft driven by a spatial RSSR mechanism.The coordination between the transmission mechanism and the flapping mechanism is analyzed and compared;based on the aerodynamic characteristics of the wingspan,the good coordination between the mechanisms and the strength conditions of the selected flapping materials are verified.Modal simulation analysis of the overall model is conducted to study the influence of the transmission mechanism on the motion characteristics of the flapping mechanism;through fluid simulation analysis,the aerodynamic characteristics of the two flapping modes are obtained,verifying the feasibility of the flapping-wing aircraft.
