When drones fly in sandy environments, existing sandblasting pipes cannot effectively simulate the movement trajectory of sand particles in nature, resulting in inaccurate sand blasting tests.

Method used

Design a sandblasting pipe, including a sandblasting pipe, a conveying pipe and a sand outlet pipe. Sand particles are mixed with high-pressure gas in the sandblasting pipe and then conveyed to the sand outlet pipe through the conveying pipe. The sand outlet pipe is provided with a vertical section, a horizontal section and an impact section. The sand particles are impacted twice in the vertical and horizontal sections and the impact section, and finally fly out from the gap of the connecting arm.
