Abstract In order to study the cross wind effect on the influence of pitch angle on the overall aerodynamic performance of propeller, CFD software was used to solve N-S equation of unsteady incompressi-ble flow and S-A turbulence model, based on sliding mesh technology and dynamic mesh technology. The aerodynamic characteristics of propeller under static change and dynamic change of pitch angles were numerically simulated, respectively. The static pitch angles were 0?, 3癮nd 6?. The dynamic change of pitch angle indicates pitch angle sinusoidally varied from 0皌o 4?. The numerical results indicates that in the static process, the tension and torque increase linearly with pitch angle, while the efficiency decreases. Compared to the case of pitch angle of 0?, the tension increases by 20%-30% and the torque increases by 30%-40% for pitch angle of 3?. In the dynamic process, the tension, torque and power increase linearly with pitch angle, while the efficiency decreases. Moreover, the aerodynamic parameters at pitch angle of 3癷n the static process approximately equals that at the same pitch angle of 3癷n the dynamic process, where pitch angle increases form 0皌o 4?
