Title
(EN) A METHOD FOR FORMING AN ADD-ON COMPONENT FOR AN AEROFOIL
(ZH) 一种用于形成翼型的附加部件的方法
Abstract
(EN) A method is provided for forming an add-on component for an aerofoil which enable the structure of the aerofoil to be tuned in order to reduce the amplitude of sound produced at frequency f peak when air flows in a flow direction from the leading edge over the trailing edge of an aerofoil. The method applies both to add-on components having a slitted formation and a Double-Rooted Trailing Edge Serration (abbreviated to "DRooTES").
(ZH) 本发明公开了一种用于形成翼型的附加部件的方法,能够调整翼型的结构,以降低当空气沿从翼型前缘流过翼型后缘的流动方向流动时在频率f峰值处产生的声音的振幅。该方法适用于具有狭缝构造和双根部后缘锯齿(缩写为“DRooTES”)的附加部件。
