Long used by the military, drones are now used by private individuals for both recreational and commercial use.
How do they really work?
Generally speaking, a drone is characterized by 4,6 or 8 propellers.
The propeller blades of a drone are fixed, in fact, they can not change angle of inclination. The rotation of the propeller blades is alternated. In the meantime, the alternating inversion of these propellers promotes flight stability.
The principle of flight is based solely on the movement of the propellers. If all engines run at the same speed, the drone will hover.
To make a movement, advance or back up, the success of the flight is played on the front and rear engines. Similarly, for the right and left movement of the arms. The slowing of the right engines favors the movement to the right. To rotate, increase the speed of motors aligned on an axis. In addition, a drone is also equipped with several technologies. It is powered by an electrical power namely polymer lithium batteries.
How to control the navigation?
The control of a drone requires a particular technique that the individual must learn. Like other flying machines, drones move in the air. The blades of the propellers allow it to perform the flight. Thanks to navigation electronics, you can control a drone from the ground.
The latter obeys you with the finger and the eye. Using a specific device called a radio controller, you can easily influence the movements made by your multirotor. Then the barometer accurately measures the altitude traveled by this flying device.
Finally, using a GPS, you can easily detect the position of your drone. In general, a drone has an autonomy of between 5 min up to 1 h. Most drones can carry mass objects between 1 kg and 10 kg like cameras and video gear. Some custom drones can load large masses.
Thus, the payload of drones depends on the reason for use.
How to choose your drone?
Known as UAVs, drones play several roles in different areas. Now they are accessible to the general public and can be purchased in the department stores or online.
Whether for professional use or just for fun, the choice of the type of drone must be made depending on your use and needs.
At the moment, drones exist in several models, sizes, pace … Each has distinctive features that make them better. Find more on the trendiest drone of 2017 www.le-mavic.fr
