Drones were initially used by the military for surveillance purposes, but these days they are popularly used in photography and videography due to their adaptability in performing aerial maneuvers while recording stunning images during a flight on high-definition, now we discuss how different drones work.
1) Quadcopter drones
Quadcopters are unmanned, remote-controlled vehicles often used for aerial photography. They come with four rotors mounted on arms diagonally which are responsible for providing the thrust needed to lift off, hover, and cruise through the air. These ingenious devices have become extremely popular because of their ability to fly in any direction or angle. Quadcopters can perform various movements that defy gravity such as flipping over 360 degrees by rotating around their axis without changing the altitude. This is made possible by an automatic leveler that is responsible for establishing a fixed position in mid-air. Another interesting feature is this device’s capability to reorient its lightweight carbon fiber frame if it gets inverted during flight, thanks to flybar paddles. They are made of metal or carbon fiber rods that facilitate the rotational motion of quadcopters’ arms. Quadcopters come in two flavors, brushed and brushless. The former is equipped with smaller brushless DC motors whereas the latter is powered by more powerful brushless AC ones.
2) Fixed-wing aircrafts
Fixed-wing aircraft have wings that provide them with an aerodynamic lift so they can fly for a longer duration of time without requiring to land now and then to recharge their batteries. These drones have ‘fixed’ wings which means there is no flapping involved, unlike traditional plans. This feature makes them very efficient because their energy consumption is relatively low compared to other aerial devices that lack autopilots. Their symmetrical and rigid wing structure gives them the ability to fly in any direction without having to adjust their angles. They cannot dive, climb or turn like quadcopters, but they are much faster than other types of drones. Therefore, if you need a device that can fly straight for a long distance, fixed-wing aircraft will be your best bet.
3) Hybrid Drones
Hybrid drones come with both fixed wings and rotors mounted on arms which allow them to take off and land vertically while cruising through the air by flapping their wings. The air pressure exerted against these rotating blades causes lift that allows aerial devices to gain altitude during flight. This is a great feature that makes these aerial devices very agile and maneuverable. Their flight stability can be further enhanced by deploying electronic stabilization features such as GPS, accelerometers, and gyroscopes. The latest example is DJI’s James Bond-inspired quadcopter drone called ‘Inspire 1’, a beautifully engineered piece of equipment that comes with a 4K high-definition camera tightly integrated within its fuselage.
How do drones differ from traditional aircraft?
Contrary to what many people think, aerial drones are not airplanes because they have different characteristics compared to the ones used in the commercial aviation industry. They lack landing gears because their purpose is quite different from airplanes. In addition, they don’t have pressurized cabins for comfort. If you are wondering whether drones are piloted by people then the answer is ‘No’. Drones have automatic pilots that guide them through the sky. They do not need to be monitored by a man because their autopilots take care of them during flight.
