How much damage can a tiny drone propeller really do when it comes up agains something as solid as a person? That’s the question Aalborg University in Denmark is answering with a rig that can ram a spinning drone propeller into a piece of flesh at 33mph… and record the results in slow motion.
The video is an accurate (if slightly gruesome) demonstration of what could happen if you lose control of your drone and it hits a person, propeller spinning. And if you’re like us, it’ll have you extra careful the next time you pilot that DJI of yours.
In the video above, the 10-foot long rig fires a spinning drone propeller at a piece of raw pork roast, capturing the resulting collision at up to 3,000 frames per second so they can analyze how the propeller behaves when it hits flesh, and the extent of the damage it can do.
The results will hopefully help engineers develop future propellers that break apart more easily and do less damage if they do somehow make contact with an unsuspecting human.
RESEARCH CATAPULT TESTS THE DANGERS OF DRONES
At Aalborg University’s Drone Research Lab, a new experimental setup with a motorized catapult and high-speed camera now documents in detail what happens when one of the popular small hobby drones hit objects or people. In the first film from the lab, drones are sent on a collision course with a pork roast.

- The objective is to examine the consequences when different kinds of drones hit people, animals, cars, glass panes and other obstacles they may encounter in their path. With a high-speed camera and precise measurements of both the speed and the force of the collision, it is possible to assess the damage that may occur, says Anders la Cour-Harbo, director of the drone lab.
The catapult was built by the university specifically for this type of experiment and it is still in the testing phase. The videos show the very first experiments for adjusting the mechanics and electronics of the catapult. In addition, researchers are still working on optimizing the light and camera setup, so registration will be as good as possible.
- The first attempts are interesting because they clearly show what could happen when a regular hobby drone hits a human being. But it’s too early to conclude anything, emphasizes Anders la Cour-Harbo. Particularly in the tests simulating collisions with people, it is necessary to do it absolutely right and verify that the results are reliable. The university is thus working with Aalborg University Hospital to conduct experiments that can help us better understand how dangerous drones really are.
The actual catapult is nearly three meters long and built of aluminum. The slide is pulled by an electric motor. It can accelerate a 1-kilogram drone up to 15 meters per second and the collision is filmed with a high-speed camera with over 3000 frames per second. The force of impact is measured over time as this is important for the extent of the injury. Once the researchers get more experienced, the plan is to upgrade the catapult for larger drones and higher speeds.
Man what a joke. How much money did this thing cost. Ask any one who has started a engine with a prop on it what happens if one does not get there fingers out of the way. Why have the RC model airplane guys gone to starting sticks and electric starters? Goodness, how many people are killed each year by hot air balloon accidents? Yet hot air balloons are PC OK while they try to make drones a dirty word and distract people from the real problems in the world. Surely the folks doing this have better things to do with there time. Then again, why go have fun when you can force others to live like YOU think they should. Bunch of evil jokers. Lets outlaw everything dangerous, starting with bicycles, skying, automobiles and any kind of moving machine. While you are at it, have to get rid of horses as well. They are very dangerous and kill many a year. People need to get a life, then they probably do not have enough brains to do so. Ask what happens when someone walks into a small airplane prop on an idling engine, happened not to long ago. Man I get tired of idiots trying to force there stupid on me.
So, I'm always on the lookout, for new and/or interesting things, to share with my Fellows of Phantom Familia, pilots.
Sorry it isn't always drone related, and I have already inquired about having an Off Topic section within the forum, perhaps not linked to the All section.
Thanks to the www2, the floating world and our nearest planets are all at our finger tips. That would be two-thumbs, for the folks using their cell's here or to fly. Hahaha
