What is a drone and how does it fly?
A drone, also known as an unmanned aerial vehicle (UAV), is a remote-controlled or autonomous aircraft that can fly without a human pilot on board. Drones fly by using a combination of sensors, GPS, and rotors to lift off the ground and navigate through the air. The sensors and GPS work together to provide stability and direction, while the rotors generate lift and propulsion.
The rotors, which are usually multiple in number, are paired with electric motors that spin at high speeds to create the necessary lift and thrust. As the rotors spin, they create a difference in air pressure above and below the drone, allowing it to rise into the air and move in any direction. By adjusting the speed and angle of the rotors, the drone can be controlled to fly steadily, turn, and even hover in place.
What are the main components of a drone?
The main components of a drone include the airframe, motors, electronic speed controllers, propellers, flight controller, sensors, and battery. The airframe is the physical structure of the drone, which can vary in design and material depending on the intended use.
