In order to optimize the aerodynamic performance of coaxial twin-rotor unmanned aerial vehicle in hovering,improve the handling performance and endurance ability,the aerodynamic analysis of coaxial twin-rotor unmanned aerial vehicle with different pitch spacing ratios was conducted.The power load and hovering efficiency of coaxial twin-rotor unmanned aerial vehicle were theoretically modeled and analyzed.The power and lift with different pitch spacing ratios were analyzed through simulation and experiment.The sliding grid method was used to simulate the change of lift and torque,as well as the flow field and pressure distribution.The result shows that the pitch spacing ratio is 0.4 with a fixed speed,the aerodynamic performance of coaxial twin-rotor unmanned aerial vehicle is the best.
