摘要： A variable camber airfoil has a leading portion and a trailing portion that is pivotally coupled to the trailing portion. A flexible skin substantially encloses the leading portion and the trailing portion and generally defines an airfoil profile. The skin is fixedly coupled to the trailing portion and is slidably coupled to the leading portion. Upon movement of the tail portion, the skin changes position with respect to the leading portion, and the internal structure of the wing changes the profile of the wing. The internal support structure of the wing supports a pivot bar that extends from the leading portion to the trailing portion. The pivot bar is pivotally connected to the support structure. One end of the pivot bar is coupled to the trailing portion, and the other end of the pivot bar is coupled to a movement linkage. The operator controls are ultimately coupled to the pivot bar. A plurality of support arms are coupled between the skin and the support structure. The support arms position the skin with respect to the support structure. When increased lift is desired, the tail pivots downward and the skin slides about the nose so that the upper portion of the skin extends further from support structure and lower portion of the skin is brought closer to support structure. The opposite is true for a reduction in lift.

摘要翻译： 可变的弧形翼型件具有前端部分和后部，其可枢转地联接到后部。 柔性皮肤基本上包围前导部分和尾部，并且通常限定翼型轮廓。 皮肤固定地联接到后部，并且可滑动地联接到引导部分。 在尾部移动时，皮肤相对于前端部改变位置，翼的内部结构改变翼的轮廓。 翼的内部支撑结构支撑从引导部分延伸到尾部的枢轴杆。 枢转杆枢转地连接到支撑结构。 枢转杆的一端联接到后部，并且枢转杆的另一端联接到移动连杆。 操作员控制器最终联接到枢轴杆。 多个支撑臂联接在皮肤和支撑结构之间。 支撑臂相对于支撑结构定位皮肤。 当需要增加提升时，尾部向下枢转并且皮肤围绕鼻子滑动，使得皮肤的上部部分从支撑结构进一步延伸，皮肤的下部更靠近支撑结构。 电梯减少的情况恰恰相反。
