The invention provides an aircraft stealth wing which comprises a water-drop-shaped wing base body and a sinking face arranged at the front edge of the wing base body in a sinking mode, the bottom of the sinking face is an inclined face inclining outwards, a coating layer used for absorbing electromagnetic waves is arranged in the sinking face, the coating layer is in a crescent shape, and the thickness of the coating layer is larger than that of the water-drop-shaped wing base body. The front edge of the wing base body is covered with the coating layer, the coating layer and the outer surface of the wing base body are in smooth transition, and the end face of the free end of the wing base body is provided with a stealth structure layer used for absorbing electromagnetic waves. The front edge part of the wing base body sinks, and the sinking surface is filled with the camouflage coating, so that the overall size of the wing is not changed, the aerodynamic shape of a product can be ensured to be unchanged, and the wing has a camouflage function under the condition that the rigidity and the strength of the wing meet the requirements; the front edge sinking surface is arranged to be a variable cross section, a horizontal step surface is prevented from being formed at the junction of the wing base body and the coating layer, and therefore the echo attenuation effect is achieved.

    本发明提供了一种飞行器隐身机翼,该机翼包括水滴状的机翼基体和下沉设置于机翼基体前缘的下沉面,所述下沉面底部为向外倾斜的斜面,所述下沉面内设置有用于吸收电磁波的涂料层,所述涂料层呈月牙形,所述涂料层覆盖于机翼基体前缘,所述涂料层与机翼基体外表面平滑过渡,所述机翼基体自由端的端面设置有用于吸收电磁波的隐身结构层。本发明通过在机翼基体前缘部分下沉,再使用隐身涂料对下沉面进行填充,因此,不会改变机翼整体尺寸,可以保证产品气动外形不变,使得机翼刚度和强度满足要求情况下,同时具有隐身功能;前缘下沉面设置成变截面,避免机翼基体与涂料层交界处形成水平台阶面,从而实现回波衰减效果。
