Abstract

To evaluate the performance of coaxial rotor in hover, the experimental test rig was designed and measurement of thrust, moment and hovering efficiency for the single and coaxial rotor was carried out. With the change of pitch angle, rotating speed, solidity, and stage spacing, the aerodynamic performance of the coaxial rotor was evaluated and compared to single rotor under similar working conditions. The performances of upper rotor and lower rotor were compared with single rotor. Under torque balance d state, the coaxial rotor achieves higher (FOM) figure of merit than the non-balanced state, the optimal pitch angle was obtained with maximum FOM 0.65.
