The invention discloses a subsonic velocity wing with a porous medium trailing edge, which comprises a wing body and the porous medium trailing edge, and the porous medium trailing edge is embedded at the tail part of the wing body. The shape of each spanwise section of the wing body is the same, and the wing body is made of a non-metal material or a metal material; the porous medium trailing edges are symmetrically distributed on the wing body, and the porous medium trailing edges are made of an isotropic porous medium material with 35PPI-80PPI and porosity of 74.8%-88.4%. A part of the tail edge area of the original wing tail is replaced by the porous medium material, so that the flow separation of the wing tail is reduced, and the lift force drop caused by the flow separation is weakened.

    本发明公开了一种带有多孔介质尾缘的亚声速机翼,包括机翼本体和多孔介质尾缘,多孔介质尾缘镶嵌于机翼本体尾部。机翼本体各展向剖面形状相同,机翼本体采用非金属材料或金属材料;多孔介质尾缘在机翼本体上呈对称分布,多孔介质尾缘采用35PPI~80PPI,孔隙率为74.8%~88.4%的各向同性多孔介质材料。本发明将原始机翼尾部的部分尾缘区域更换为多孔介质材料,减小机翼尾部的流动分离,削弱由流动分离引起的升力下降。
