Bird strikes are a very real danger to planes in flight, and consequently aircraft are required to undergo bird strike testing — but what about drones? With UAV interference at airports on the rise, drone strike testing may soon be likewise mandatory, and if it’s anything like what these German researchers are doing, it’ll involve shooting the craft out of air cannons at high speed.

The work being done at Fraunhofer EMI in Freiburg is meant to establish some basic parameters for how these things ought to be tested.

Bird - Strikes - Example - Poultry - Bird

Bird strikes, for example, are tested by firing a frozen poultry bird like a chicken or turkey out of an air cannon. It’s not pretty, but it has to be done. Even so, it’s not a very good analogue to a drone strike.

“From a mechanical point of view, drones behave differently to birds and also weigh considerably more. It is therefore uncertain, whether an aircraft that has been successfully tested against bird strike, would also survive a collision with a drone,” explained Fraunhofer’s Sebastian Schopferer in a news release.

Team - Air - Drone - Batteries - Engines

The team chose to load an air cannon up with drone batteries and engines, since those make up most of any given UAV’s mass. The propellers and arms on which they’re mounted are generally pretty light and will break easily —...
