As the World is constantly evolving in the field of innovations and technology, we are interacting more with AI’s. One such form of AI is Drone, also named as the unmanned aerial vehicle(UAV) 

Drone, the word tends to be rocket science but it’s much easier than that. It is an autonomous aircraft that flies across the skies effortlessly like a bird. It is usually piloted with the help of a smart device such as smartphones and tablets or with the help of a joystick.

Discussing a Quad-copter drone, which is used in various fields for research and development and even for recreational purposes, it’s operation is not a strenuous task. These aerial gymnasts are more than what they seem to be. A typical drone is made up of lightweight materials in order to reduce weight and increase its effectiveness.

But what actually makes the drone fly?

Know how a Quadcopter Drone works:

It is physics playing its part. In this article, we would be learning about all the forces which make the drone fly.

Propulsion and control of a drone are obtained by the rotors. You might think of rotors as fans as they operate in the same way. As all the forces come in pair the spinning blades which push the air down, in return get raised by the force of the air below it. That is the basic principles behind lift, greater the spin rate greater will be lift and converse.

Throttle and Hover:

The quadcopter drones also known as the multi-rotor drones are raised and controlled by four rotors. These four spinning rotors push the air in a downward direction and in complement to this force the air pushes and lifts the aircraft. The amount of lift of the aircraft depends directly on the speed of the rotor. The net force of all four rotors needs to be equal to the gravitational force of the earth for a drone to float in the air. When the rotor speed increases (net force is upward in direction), the drone will ascend or climb, and descend when the speed decreases (net force is downward in direction).

Roll and Pitch:

Well, that was all about how a drone floats, climbs or descends. But for a drone to turn and tilt to the left-right (Roll) or forward-backward (Pitch). We need to control the speed of a particular pair of propellers.

For example, we need to tilt the aircraft towards it’s right then we have to increase the spin rate of the pair of propellers on the left-hand side and simultaneously decrease the spin rate of the right-hand side propellers. This principle is valid for tilting the aircraft forward and backward.

Yaw:

YAW is the movement around the vertical axis which lies perpendicular to an aircraft’s wings and in the middle section. It pushes the Quadcopter in a clockwise/anti-clockwise motion as it remains at ground level.

The diagonal pairs of the drone will move in the same direction while the other two will move in the opposite direction.
