UAV Dynamic system Test experimental training teaching course （Ⅱ）

2. Content of experiment and training

1. Preparation for experiment:

Preparation of experimental equipment and tools;

WF-EDU-02 test bench: test bench main body, isolation cage, power line, data line;

Dynamic system: 20A electric adjustment, 3S battery (can be replaced by the internal power supply of the test bench), two groups of motors and propeller;

There are two groups of motors and propellers:

The first group of motor and propeller: motor model 2312-KV1000, propeller model 9450;

The second group of motor and propeller: motor model 2312-KV800, propeller model 1045;

Other assembly tools: hexagon socket, bolt, propeller assembly clamp.

2. Automatic test of dynamic system

(1) Complete the installation of the first group of motor and test stand, test stand electricity, software connection, the ESC stroke calibration, motor steering adjustment and the installation of the first group of propeller by referring to the operation experiment steps of experimental Course 1 and Course 2, and adjust the voltage to 11.4V.

(2) Open the safety protection interface, set the protection mode to warning and close the throttle, click Enable protection, set the current protection threshold to 15A, and set the temperature protection to 60 degrees Celsius.

(2) Click the test information, fill in the test information in the software test information bar, and save it.

Figure 2.2 Filling in test information

(3) Automatic test Settings can be completed in two ways

The first method: click the automatic test TAB in the test software and set the test mode to "growth". All throttle points can be set uniformly by throttle growth and hold time. This test can set the single increase to 5% and the throttle point duration to 5s, and click Save.

The second way: click the automatic test TAB in the test software, set the test mode to "Custom", increase or decrease the test point, and set the test throttle value and hold time of each point (unit: 0.1s), after setting, click Save.

Figure 2.3 Automatic test "custom" mode Settings

Note: Due to the actual working state of the dynamic system, throttle value is generally above 20%, so UAV dynamic system that testing data generally do not need to start from 0% throttle point for testing, but can be tested at 10% or 20% throttle point as the first test point.

(4) Adjust the test bench voltage to 11.4V, click toggle clear and current clear, click the throttle to unlock, and finally click Automatic test, WF-EDU-02 test bench starts automatic test. After the automatic test, the software saves the data automatically.
