用于扇形叶片的张力扭矩传递元件及其制造方法

Tension-torque-transmission element for a fenestron blade and method for producing it
Abstract:
A tension-torque-transmission element (3; 3′; 4) for a rotor blade of a rotary wing aircraft (helicopter), in particular for a fenestron blade of a tail rotor, with a connecting section on the blade side and a connecting section (30; 30′; 40) on the axis side, with a connecting eye (32) on each connecting section, and with a torque-transmission section (34; 34′; 44) that connects the connecting sections (30; 30′; 40), is improved in that the tension-torque-transmission element (3; 3′; 4) is designed in a fiber-reinforced composite design including several layers (A to G) of a textile fabric. A method for producing such a tension-torque-transmission element (3; 3′; 4) is also described.
Abstract(Chinese):

一种用于旋转飞行器（直升机）的转子叶片的拉力扭矩传递元件（3; 3'; 4），特别是用于尾部转子的前叶片，在叶片侧具有连接部分， （30; 30'; 40），在每个连接部分上具有连接眼（32），以及扭矩传递部分（34; 34'; 44），其连接连接部分 改进了张力扭矩传递元件（3; 3'; 4）被设计成包括织物的几层（A至G）的纤维增强复合材料设计。 还描述了制造这种张力扭矩传递元件（3; 3'; 4）的方法。
