摘要：
In order to investigate the variation characteristics of the pressure fluctuations induced by a propellerwith change of the advance coefficient, the pressure sensor and LMS Test.Lab acquisition system are employed while the pressure fluctuations are experimentally studied on a 7-blade high-skewed propeller and a 3-blade conventional propeller innon-uniform flow. The results show that the first four orders of the blade frequency humorous components of the pressure fluctuations induced by the 7-blade high-skewed propeller and the first two orders of the blade frequency humorous components of the pressure fluctuations induced by the 3-blade conventional propeller decrease first and then increases with the growth of the advance coefficient. The advance coefficients corresponding to the minimum value of the blade frequency humorous components of the two propellers are approximately 1.1 and 0.85, respectively.For the 3-blade conventional propeller, the third order and the fourth order of the blade frequency humorous components of the pressure fluctuations presents a gradually increasing variation trend when the advance coefficient increases. Through mathematical regression analysis, the first order of the blade frequency humorous components corresponding to the 7-blade high-skewed propeller and the 3-blade conventional propeller have quadratic functional relations with the advance coefficient. © 2017, Editorial Department of Journal of Propulsion Technology.
