The invention discloses an empennage structure for improving FSAE racing car flow field adaptability. Owing to the fact that the middle of a main wing and the middle of a flap are both arched upwards, the main wing and the flap, compared with a common flat and straight wing piece, can reduce the influence of upstream components on downward pressure so as to increase the downward pressure; besides, an arc-shaped part is arranged at the lower end of an end plate, the arc-shaped part generates a radian, the influence of an upstream flow field on the lower surface of the empennage is weakened, and the downward pressure generated by the empennage of the FSAE racing car is ensured. The empennage is simple in structure, high in reliability, low in cost and good in popularization value; the empennage can be ensured to adapt to more kinds of working conditions; the empennage can be ensured to adapt to more kinds of working conditions and different airflow conditions, such as different air density, humidity, temperature and the like.
本发明公开了提高FSAE赛车流场适应性的尾翼结构,由于主翼和襟翼中间均向上拱起,相较于常见的平直翼片,该主翼和襟翼均能减弱上游部件对下压力的影响,以增加下压力。且,端板下端设置有弧形部,该弧形部产生了一个弧度,减弱了上游流场对尾翼下表面的影响,从而保证FSAE赛车尾翼产生的下压力。同时,该尾翼结构简单,可靠性高,成本低,具有很好的推广价值。也可保证该尾翼能适应更多种类的工况。也可保证该尾翼能适应更多种类的工况,不同的气流条件,如不同的空气密度、湿度和温度等条件。
