低噪声对转螺旋桨的翼型—螺旋桨一体化设计方法

根据先进翼型设计方法和对转螺旋桨设计方法，研究发展了一种低噪声对转螺旋桨设计方法。该方法通过翼型设计和对转桨设计的交替应用和研究设计具有较好空化特性的先进翼型，使对转螺旋桨在具有较高效率的同时，桨叶各剖面的空化数与抗空化翼型的空化特性要求相符合，以避免或减弱叶片表面空化的发生，从而降低了桨叶的噪声。根据这一方法对某对转螺旋桨进行了设计。

An Integrated Design Method of LowNoise Contrarotating Propellers

Based on the methods for advanced airfoil design and contrarotating propellers design, a new integrated design method has been developed for low noise propellers. In the method an interactive design process of airfoilpropeller is adopted in order to obtain better matching performance of airfoils and propellers, especially for cavitation noise reduction. A pair of contrarotating propellers using WPQ cavitationresistant airfoils has been designed by the integration method.
