Question

how a drone works plz tell me​

Answer 1

Answer:

Frame

the frame is commonly made of sturdy but lightweight composite material such as plastic (in cheap models), fiber glass, or carbon fiber, but low-density metals such as aluminum and titanium are also used. The frame provides the central hub that houses the electronics mounted in the drone. Almost all quadcopter frames have a central hub from which spokes radiate outwards. It is on these spokes that the rotors are mounted.

The frame needs to provide a water-proof encasement for the motor. Some models also incorporate rotor guards to the frame, protecting the rotor from damage and also making the drone safer to handle for the operator.

Propellers

The propellers are responsible for all aspects of drone movement – whether it be stationary hovering, turning, tilting, or moving forward and backward. Aside from providing vertical lift, variations in the rotational speed of individual rotors allow the drone to make very fine and responsive maneuvers. Most drone propellers are made of plastic, while the more expensive models have propellers made of carbon fiber.

Motor

The motor provides the rotational power to the rotors. Many drones use brushless motors which are more efficient to brushed motors because of the decreased loss of energy due to friction between the brushes of the motor commutator. The increased efficiency is very important in saving battery life, therefore giving longer flying times.

Battery

The battery used to power the rotors and other onboard electronics in a drone is commonly the lithium polymer type. “Li-Po” batteries are known for being small and lightweight, with high energy density and high discharge rate. They can be quite tricky to handle and store compared to more conventional batteries, but Li-Po batteries have traits that make them uniquely appropriate for drone flight.
