How serious will a falling drone on your head cause? A study done by US Federal Aviation Administration (FAA) has brought out the figures after discussions, findings, that chances of a head injury from a falling drone to be 0.03 percent.
The drone crash test started in September 2015 and was being conducted by the Alliance for System Safety of UAS through Research Excellence (ASSURE). It includes the collaboration of researchers from University of Alabama in Huntsville, the University of Kansas and Mississippi State University, and they intend to bring about public awareness regarding the risk of surrounding drones and the wider public.
According to the FAA official website, the University of Alabama in Huntsville’s David Arterburn, principal investigator for the study said “The research team reviewed over 300 publications from the automotive industry, consumer battery market, toy standards and other fields to inform their research using the most modern research techniques. From these, we were able to identify blunt force trauma, penetration injuries and lacerations as the most significant threats to people on the ground.”
Being a part of the research, the team of researchers carried out several crash test to investigate kinetic energy, energy transfer and the dynamics of a collision between a falling drone and a human head. NASA, the Department of Defense and FAA scientists then reviewed the results.
They compared the velocity and change of injury when struck by a drone and also a piece of wood or steel of the same weight. The researchers found out that a 1.22 kg (2.7 lb) drone crashing on a human head brought a 0.01 to 0.03% chance of head injury, while neck injury was at 11 to 13 percent and compared to the wood and steel of the same weight caused a 99 to 100% chance of head injury and 60 to 70 percent of neck injury.
The study found that drones cause less damage because they fall more slowly than other materials due to the aerodynamic drag. A drone is also transferring lesser energy in the falling process, being more forgiving and will flex more on impact.
