Civilian Light and Small Unmanned Aerial Vehicle System Wind Resistance

According to Table 1 and Table 2 of GB/T38930-2020, graded design is required.

2.1 Wind resistance capability

0.25<Maximum takeoff weight<=150 (Kg) 0-6 levels

Wind speed: 0.0-25 (m/s) (maximum level 9) Accuracy>=1m/s Timer: 30s, 5min or any setting.

2.2 Flight position measurement

Flight accuracy: horizontal<=10cm; vertical<=15cm; attitude angle:<=1; interval accuracy:<=0.5s; timing accuracy:<=0.1s

2.1 Wind field environment measurement

Temperature: 15-35 Humidity: 20% -80%;

Air pressure: 86KPa-106KPa

The instruments and equipment used for testing (including specialized equipment) should be verified or calibrated and within their validity period, and the accompanying testing equipment should be inspected and qualified. The testing instruments used should meet the expected usage requirements, and their measurement uncertainty or maximum allowable error should be less than one-third of the maximum allowable error of the measured parameter. The testing equipment and instruments used are as follows:

a) Wind field simulation system: The wind speed adjustment range should be at least 0m/s~25m/s, and the accuracy should be 1m/s1

b) Flight accuracy measurement system: used to measure the position and angle changes of unmanned aerial vehicle systems during flight, and the horizontal measurement accuracy should be

10 cm， The vertical measurement accuracy should be 15cm, the angle measurement accuracy should be 1, and the measurement interval time should be 0.5s; c) Timer: The measurement accuracy should be 0.1s
