Team Studies Drone Strikes on Airplanes by Firing Them into a Wall at 500 MPH

The institute has begun to perform initial impact tests with drone batteries and motors. “Using compressed air, we accelerated these two components to speeds ranging from 115 to 255 meters per second and fired them at aluminum plates up to eight millimeters in thickness that were mounted in a test bench,” Dr. Sebastian Schopferer, a scientists working on the project, explains…. “There was substantial deformation and indentation of the plates, and the drone battery and engine were completely destroyed.”
