Flying drones – the spectacle in our time is more than ordinary. But very few people imagine what actually happens with the flow of air around the vehicle hanging in the sky. Researchers at NASA’s Ames Research Center in California, developing a computer model, created an animation of the airflow from the four working screws of the Phantom 3 quadrocopter.
Animation reveals complex air fluctuations, formed by the work of the rotors of the drones and its X-shaped frame. For decades, NASA has been using computer simulations to analyze the flow of air around experimental aircraft models. With reference to kvadrokopteru it was made for the first time.
Copter Phantom 3 is equipped with four electric motors with screws, which produce enough traction to lift the entire apparatus 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 for a drone twice as great thrust.
