The invention provides a slotted guide vane type high lift device. A method comprises the steps: performing slotting on an airfoil upper surface and an airfoil lower surface; performing rounding and shaping treatment on the seam opening A1, the seam opening B1, the seam opening C1, the seam opening B2 and the seam opening C2; performing second-time rounding and shaping treatment on the slotted position, namely the position A1 of a slotted opening, of the wing type rear part of the slotted wing, the radius of an inscribed circle ranges from 0.05 c to 0.4 c, and forming a flow deflector by the cut rounding; enabling the flow deflectors to move upwards in the normal direction of the underground surface at the thickest positions of the flow deflectors, wherein the moving range is 0.005 c-0. 2 c; finally, forming the layout that the flow deflectors are additionally arranged at the seam opening, and obtaining the slotted flow deflector type high lift device. According to the slotted flow deflector type high-lift device, the maximum lift coefficient of the airfoil can be remarkably improved, the stall characteristic of the airfoil is greatly improved, the slotted flow deflector type high-lift device is a simple and efficient novel high-lift device, and then the aerodynamic performance and the control stability of an aircraft are effectively improved.
本发明提供一种开缝导流片式增升装置,在翼型上表面和翼型下表面开缝;在缝道口A1、缝道口B1、C1点、缝道口B2、C2点进行倒圆修形处理;在开缝翼翼型后部分上开缝位置,即缝道口A1位置进行第二次倒圆修形处理,内切圆半径范围0.05c~0.4c,切割下的倒圆形成导流片;将导流片沿着导流片最厚位置的当地下表面法向方向向上移动,移动范围为0.005c~0.2c,最终形成缝道口增加导流片的布局,即得到开缝导流片式增升装置。本发明提供的一种开缝导流片式增升装置,可以实现翼型最大升力系数的显著提高,翼型的失速特性得到极大的改善,是一种简单高效的新型增升装置,进而有效提升飞行器气动性能及操控稳定性。
