The invention provides a stall detector, an electronic pneumatic stall warning system and a general airplane. A stall detector for mounting to a wing of an aircraft includes: a weather vane blade extending from a leading edge of the wing and swinging in a direction of an upper airfoil of the wing under the action of a pressure difference between the upper airfoil and a lower airfoil of the wing; afixed lining plate which is arranged on the surface of the front edge of the wing, the fixed lining plate is provided with a limiting opening, and the weather vane blade extends out through the limiting opening; and a heating assembly which is arranged in the wing, is electrically connected with the weather vane blade and the fixed lining plate and is used for heating the weather vane blade and the fixed lining plate. The stall detector provided by the embodiment of the invention is more sensitive and quicker in stall detection.
本申请提供一种失速探测器、电子‑气动式失速告警系统及通用飞机。一种用于安装到飞机的机翼上的失速探测器包括:风标叶片,从机翼前缘伸出,在机翼的上翼面与下翼面之间的压差作用下向机翼的上翼面方向摆动;固定衬板,设置在机翼前缘表面,所述固定衬板具有限位开口,所述风标叶片通过所述限位开口伸出;加温组件,设置在机翼内,与所述风标叶片和所述固定衬板电连接,用于给所述风标叶片和所述固定衬板加温。根据本申请实施例的失速探测器探测失速更加灵敏快速。
