The invention discloses an unmanned aerial vehicle and an airspeed meter thereof. The airspeed meter comprises a propeller, a rotating speed measurement module and a control module, wherein the rotating speed measurement module is used for obtaining the actual rotating speed of a propeller when the unmanned aerial vehicle is in a normal flight state and sending the rotating speed to the control module; and the control module is used for obtaining the actual screw pitch of the propeller and obtaining the vacuum speed of the unmanned aerial vehicle in the current flight state according to the actual screw pitch and the actual rotating speed. The airspeed meter is formed by the propeller, the rotating speed measurement module, the control module and the main body structure, and the accuracy of airspeed measurement is ensured by combining a pre-calibration process; only the propeller is exposed outside, so that the airspeed meter is prevented from being influenced by rainwater, and the cost is reduced on the basis of ensuring the measurement accuracy of the airspeed; in addition, the airspeed meter is less affected by environmental factors, namely, the use performance of the airspeed meter is improved.

    本发明公开了一种无人飞行器及其空速计,所述空速计包括螺旋桨、转速测量模块和控制模块;转速测量模块用于获取无人飞行器处于正常飞行状态时螺旋桨的实际转速,并发送至控制模块;控制模块用于获取螺旋桨的实际螺距,并根据实际螺距和实际转速获取无人飞行器在当前飞行状态下的真空速。本发明通过螺旋桨、转速测量模块、控制模块以及主体结构形成空速计,并结合事先标定过程保证了空速测量的准确性;因为只有螺旋桨暴露在外,使得空速计免受雨水的影响,在保证空速的测量精度的基础上,降低了成本;另外,该空速计受环境因素的影响较小,即提高了空速计的使用性能。
