Abstract :
The aeroacoustic characteristics of propeller-wing were simulated numerically. And the efficiency affected by the installation of angle of the propeller blade was also analyzed. Based on the pressure cloud and streamlines, This experiment used FW-H equation proposed by Ffowcs Williams and Hawkings to imitate the sound generation and dissemination.
