A quadcopter or quadroopter is a kind of helicopter with four rotating rotors that enable it to fly in the air. These four rotating rotors have been compared to the wings of an aircraft. Unlike a usual helicopter, a quadcopter has an adjustable flap on its engine cover. This allows it to change its altitude according to whether there is wind or not.
A normal helicopter does not have this kind of capability. However, a quadcopter that has a horizontal and vertical axis can be flown like a helicopter. It can also move forward and backwards using its fan blades. A quadcopter is operated using a transmitter that broadcasts a radio signal to the controller which in turn will send this radio signal down to the propeller blades. The blades will then rotate and in response the radio signal will be transmitted back to the control unit. This operation is done continuously.
There are some drawbacks of a quadcopter helicopter though. They cannot fly into areas which are too cloudy or dark to see clearly. The quadcopter will not be able to complete its mission if there is bad weather. It can only be used in clear skies or areas where it will not be interfered by external factors such as other aircraft. In addition, there are differences between a drone and a quadcopter; a drone is controllable by one person to a quadcopter needs two persons to operate it.
Another limitation of the quadcopter is the fact that it cannot fly beyond the area around it. It cannot fly beyond the line of sight and cannot hover over water. This is the main reason why the quadcopter is becoming popular among hobbyists. They can be flown indoors. You can add a propeller on it and make it fly freely over your backyard. Once you become skilled enough, you can take it outdoors and fly it over a wide area.
The use of a quadcopter is more common in the military. Military service personnel are using these drones for surveillance and target shooting. Since they are operated by one person, they can stay back and observe from a distance. They can move faster than the drone piloted planes and can have a clearer view of the ground. They also are perfect for monitoring any activity on the ground.
Recently, these quadcopters are taking the consumer market by storm. They are more advanced and are used for various commercial purposes. They can transport luggage, deliver packages, and take photos and videos with the help of a wireless remote control. They are available in three variants namely the single-engine, two-engine, and the four-engine remote controlled helicopters.
The most important component of the quadcopter is its rotor. The rotor is the one that controls the movement and direction of the quadcopter. The size and weight of the rotor are dependent on its purpose. In the case of the military, the rotor is made from lightweight materials to reduce the weight and increase the portability of the helicopter. In fact, a large number of the helicopters are being fitted with rotor systems made of carbon nano-tube because they are highly light weight and also very strong.
Quadcopter can be activated either electrically or mechanically. In the case of a power activated system, the rotor acts as an electrical motor for providing power to the other flight components. This in turn provides thrust for the propeller. Electrically activated quadcopters provide a lighter solution because they do not need any internal combustion engines to power the rotors during flight. On the other hand, mechanical quadcopters run on engines for providing thrust.
