The aerodynamic characteristics of ducted coaxial rotor were analyzed based on the numerical simulation method. The influence of ducted body on aerodynamic characteristics of the ducted coaxial rotor was discussed and also the influence of coaxial rotor spacing was investigated on lift and torque acquired by rotors above and below. The mechanism of lift produced by the ducted isolated coaxial rotor was determined by comparison of difference between ducted coaxial rotor and coaxial rotor. Numerical results show that the lift of rotor above is greater than that of rotor below at first, but then it becomes reverse as the rotor spacing is growing. The curves of ratio of lift attained by the rotor above to total tension are finally established.
Key words： ducted coaxial rotor; aerodynamics; numerical simulation; lift; torque
