Abstract

Abstract

Three blades scale model propellers with and without propeller fence along the chord direction at 88% tip blade radius are compared experimentally in the wind tunnel in respeet of aerodynamic and acoustic characteristics.Their rotational speeds vary between 1500rpm to 3000rpm.Experimental results indicate that under conditions of identical advance ratio J the efficiency of the propeller with propeller fence is enhansed 1 9%～4 9% and its lower noise level is reduced 13～20dB.It is shown that the propeller fence is one of effective measures to increase efficiency and to decrease noise of propellers.
