HIGH PERFORMANCE CONTROLLABLE PITCH PROPELLERS

In order to maximize the design of the Controllable Pitch Propellers for low acoustic signature is necessary to analyse more aspects the general features of propeller and the effect of air emission, the effect of cavitation by using different computer programme which can stimulate a lot of parameters developed on the model on scale and on the full scale model. The result made possible a new way for improvement of design techniques to obtain more and more less noisly Controllable Pitch Propellers.
