The invention discloses a variable cross-section tail wing suitable for an FSAE racing car. The variable cross-section tail wing comprises a variable cross-section wing set, an upper beam wing, a first lower beam wing, a second lower beam wing and an end plate. The variable cross-section wing group is composed of a main wing, a first flap and a second flap, the three wings are all variable cross-section wings, the variable cross-section wings are lifted up in a small whole section in the middle section of the wingspan, the main wing, the first flap and the second flap are sequentially installed between the end plates on the two sides and are approximately distributed in a diagonal mode, the second flap is provided with a Gurney flap, the upper beam wing is installed at the end corners of the end plates, and the upper beam wing is installed on the end corners of the end plates. The first lower beam wing and the second lower beam wing are distributed at the positions close to the bottoms of the end plates, the two end plates are symmetrically installed on the two sides, and the end plates are provided with shutters, end plate outer edge turnups, front edge notches, rear edge notches and flow guide strips. The variable cross-section wings can reduce the influence of turbulent flow and the like caused by the headrest on air flow, and can reduce the slippage of the air flow in the wingspan direction, so that the pressure distribution of the wing surface is relatively uniform, and the resistance can be reduced by the louver structure.
本发明公开了一种适用于FSAE赛车的变截面尾翼,包括变截面翼组,上梁翼,第一下梁翼,第二下梁翼和端板。所述变截面翼组由主翼、第一襟翼和第二襟翼组成,三片翼均为变截面翼,变截面翼在翼展中段为一小整段抬起,主翼,第一襟翼和第二襟翼依次安装在两侧端板之间,大致为对角线分布,且第二襟翼带有格尼襟翼,上梁翼安装在端板的端角上,第一下梁翼和第二下梁翼分布在靠近端板底部位置,端板有两个,对称安装在两侧,端板上带有百叶窗、端板外缘翻边、前缘缺口、后缘缺口和导流条。变截面翼能减轻头枕对空气流动造成的乱流等影响,且可以减轻气流发生翼展方向的滑移,使翼面的压力分布较为均匀,百叶窗结构则可以减少阻力。
