NASA presented the animation of the air flow of a flying quadcopter

A flying drone is more than an ordinary sight in our time. But few people imagine what actually happens to the air currents around the apparatus hovering in the sky. Researchers at NASA's Ames Research Center in California, having developed a computer model, have created an animation of air flows from four working propellers of a Phantom 3 quadcopter.

The animation reveals complex air vibrations generated by the operation of the drone's rotors and its X-shaped frame. For decades, NASA has been using computer simulations to analyze the movement of air currents around experimental aircraft models. This was the first time this was done in relation to a quadrocopter.

The Phantom 3 is powered by four propeller motors that produce enough thrust to propel the entire aircraft into the air.

As an experiment, the researchers tried to add 4 additional rotors to the computer model. It turned out that such an increase provides the drone with twice the thrust.
