The invention provides a vortex generator based on an FSAE racing car. The vortex generator comprises a vortex generator body, the vortex generator body comprises a first-stage vortex generator and asecond-stage vortex generator, the first-stage vortex generator is of a pentahedron structure, the first-stage vortex generator comprises an upper wedge-shaped plane, the upper wedge-shaped plane comprises a front-end straight line and two curved side edges connected with two end points of the front-end straight line, the free ends of the two curved side edges are arranged in an intersecting manner, a front windward side is perpendicularly arranged at the front-end straight line of the upper wedge-shaped plane, and curved side faces are perpendicularly arranged at the two curved side edges ofthe upper wedge-shaped plane; and the heights of the curved side surfaces are gradually increased from the front windward side backwards, and a lower wedge-shaped curved surface is arranged for connecting the front windward side and the curved side surfaces. The vortex generator has the advantages that the size is small, and effective vortexes can be induced at the upstream of a stall point of a wing.
本发明提供一种基于FSAE赛车的涡流发生器,包括涡流发生器本体,涡流发生器本体包括一级涡流发生器和二级涡流发生器,一级涡流发生器为五面体结构,一级涡流发生器包括上楔形平面,上楔形平面包括前端直线和与前端直线的两端点连接的两条曲型侧边,两条曲型侧边的自由端相交设置,上楔形平面的前端直线处垂直设置有前迎风面,上楔形平面的两条曲型侧边处均垂直设置有曲型侧面,曲型侧面的高度由前迎风面处向后逐渐增加,连接前迎风面和曲型侧面设置有下楔形曲面,本发明具有体积小,能够在翼的失速点上游诱导有效涡流等优点。
