The invention discloses an airfoil device, an aircraft and a stall detection method, the airfoil device comprises an airfoil structure and a stall sensor, the stall sensor is arranged on a convex surface of the airfoil structure, the stall sensor comprises a fixed friction part and a movable friction part, the movable friction part is arranged between the fixed friction part and the convex surface, and the fixed friction part is driven by the fixed friction part when no airflow acts. An included angle is formed between the movable friction part and the fixed friction part, the movable friction part vibrates under the action of airflow, so that the movable friction part and the fixed friction part are in contact and separated, an electric signal is generated, and the stall degree of the airfoil device is determined according to the obtained electric signal. In this way, stall detection can be conducted on the airfoil device through the stall sensor, and the airfoil device is prevented from losing control. Moreover, the stall sensor is simpler in structure, can be smaller in size, can be used for an airfoil structure of a small aircraft, does not need to be driven by an external energy source, and reduces the manufacturing cost.

    本发明公开了一种翼型装置、飞行器及失速检测方法,包括翼型结构和失速传感器,失速传感器设于翼型结构的凸面,失速传感器包括固定摩擦部和活动摩擦部,活动摩擦部设于固定摩擦部与凸面之间,在无气流作用时,活动摩擦部与固定摩擦部之间存在夹角,在有气流作用时,活动摩擦部发生振动,使得活动摩擦部与固定摩擦部发生接触和分离并产生电信号,并根据获取到的电信号,确定翼型装置的失速程度。如此,通过失速传感器可以对翼型装置进行失速检测,避免翼型装置失去控制。并且,失速传感器的结构较简单,体积可以做的较小,可以用于小型飞行器的翼型结构,且不需要外部能源驱动,降低了制作成本。
