The invention belongs to the technical field of radar stealth aircraft design, and particularly relates to a metal base material stealth airfoil component suitable for a subsonic aircraft and a production method thereof. A front edge of the airfoil is composed of a metal material and a wave-absorbing material. The metal material part is in a wedge shape. The wave-absorbing material part is dividedinto an upper part and a lower part which are distributed on two inclined planes of a wedge and are solidified with the wedge into a whole; a thickness of the primary wave-absorbing material close toa peak of the wedge and a bottom of the wedge is small; the thickness of the material near the middle position of the inclined plane of the wedge is large; and the solidified airfoil is smooth in appearance. The front edge of the metal airfoil is produced into a wedge shape, and the outer side of the wedge is coated with a crescent camouflage coating so that a remarkable electromagnetic echo suppression effect in a horizontal direction is realized.
本发明属于雷达隐身飞行器设计技术领域,具体涉及一种适用于亚声速飞行器的金属基材隐身翼面部件及其制备方法。该翼面前缘位置由金属材料和吸波材料两部分组成,所述金属材料部分外形为尖劈形,所述的吸波材料部分分上下两部分分布于尖劈的两个斜面上并与尖劈固化为一体,其中靠近尖劈顶点和尖劈底部位置初吸波材料厚度较薄,在尖劈斜面中间位置附近厚度较大,固化后的翼面外观光顺本发明通过将金属翼面前缘制备成尖劈形状,并通过在尖劈外侧涂覆月牙形的隐身涂料,实现对水平方向上显著的电磁回波抑制效果。
