If you have ever wondered what the aerodynamics of a quadcopter drone look like then your in for a treat. NASA recently tested the aerodynamics of a quadcopter using a 3D computer model to better understand the performance of drones,
In the short video you can easily see how the drone being tested (Phantom 3) disturbs the air and pushes it downward for thrust. While the computer model looks pretty cool, the real benefit of such testing is in helping to better understand the thrust and lift abilities of drones so better airfames can be built that allow drones to be able to lift more.
