NASA Shows Just How Powerful Drone Turbulence Can Be
Drone technology continues to evolve and become more powerful and efficient every single day. In a new video done by NASA's Ames Research Center, the site's supercomputer gave a colored rendering of exactly what the air movement around a functioning drone looks like.
The simulator uses a Phantom 3 quadcopter, a decently priced and not-too-complicated drone setup. The research showed that by doubling the number of rotors, they could double the thrust. While that might seem like common sense, it's impressive given the 'competing' air currents produced by each rotor.
And for anyone wondering about the color codes: the red sections appear to be high-pressure zones, the white is wash (air flow/disruption), and the blue is low-pressure zones.
