Embodiment Construction

[0018] Below in conjunction with accompanying drawing, technical scheme of the present invention is further described:

[0019] Such as figure 1 As shown, the UAV rotor lift test system of the present invention is composed of a brushless motor, a motor governor, a motor mount, a tension sensor, a transmitter, a lower computer and an upper computer. Among them, the brushless motor is fixed on the tension sensor through the motor mount; the tension sensor is connected to the transmitter, and the transmitter is connected to the lower computer; the brushless motor is connected to the motor governor, and the motor control is connected to the lower computer; the lower computer Connect with the host computer. When testing the rotor lift of an unmanned aerial vehicle, the rotor needs to be correctly installed on the motor shaft. The upper computer sends instructions to the lower computer, and the lower computer controls the motor governor to adjust the speed of the motor. The tension...

Abstract

The invention discloses a rotor lift force testing system for an unmanned aerial vehicle. The testing system is applied to lift force testing of a rotor of an unmanned aerial vehicle, and can be used for giving out a motor rotating speed-rotor lift force curve and fit empirical equation. The system comprises a brushless motor, a motor governor, a motor mounting base, a tension sensor, a transmitter, a lower computer and an upper computer. The lower computer has the following main functions: (1) collecting a rotor lift force signal; (2) controlling the rotating speed of the brushless motor; (3) communicating with the upper computer to transmit data; and (4) feeding back the running state of the system to the upper computer. The upper computer comprises a tension sensor correction module (1), an unmanned aerial vehicle rotor lift force testing module (2), a brushless motor rotating speed setting module (3), a system state monitoring module (4) and a testing result and system state display module (5).

Description

technical field [0001] The invention relates to an unmanned aircraft rotor lift test system, which is particularly applied to the lift test of an unmanned aircraft rotor, and belongs to the technical field of unmanned aircraft tests. Background technique [0002] In the development process of unmanned aerial vehicles, it is necessary to test the motor speed and rotor lift of unmanned aerial vehicles. At present, none of the UAVs produced by domestic civil UAV manufacturers has undergone this test; in order to improve the flight reliability of the quadrotor aircraft and reduce the risk of losing control, it is very necessary to implement the rotor lift test test. Contents of the invention [0003] The object of the present invention is to provide a kind of unmanned aerial vehicle rotor lift test system, and its main purpose is: (1) test the lift of rotor at different rotational speeds; (2) empirical formula of fitting rotational speed and rotor lift relation. [0004] The ...
