The invention discloses a hybrid laminar flow wing suitable for a double-fuselage layout demonstrator. The hybrid laminar flow wing is arranged between the double fuselages; the center of a front edgewall plate of the hybrid laminar flow wing is an air suction control area; air suction holes are uniformly formed in the air suction control area; an air suction cavity is formed below the air suction control area, the upper surface of the air suction cavity is communicated with the air suction hole, and the lower surface of the air suction cavity is connected with the mixed laminar flow air suction control device. Negative pressure is formed in the air suction cavity in the wing section, the head speed of the wing section is changed, the laminar flow area range of the wing section is enlarged, and flight resistance is reduced.
本发明公开了一种适用于双机身布局验证机的混合层流机翼,所述的混合层流机翼设置在双机身之间,混合层流机翼前缘壁板正中央为吸气控制区域,所述的吸气控制区域均匀布置有吸气孔,吸气控制区域下布置有吸气腔体,吸气腔体上表面与吸气孔相通,下表面与混合层流吸气控制装置相连,本发明通过在翼段内部吸气腔体形成负压,改变翼段头部速度型,扩大翼段层流区范围,降低飞行阻力。
