Since 2013, more and more media and public discussion about a drone, this more before being used for military purposes and the city surveying and mapping machine that, like a growing number of smaller and smaller at the same time, into more people's vision.
So, how fire the drones are now? because proposed Wang Feng was known as Xinjiang, for example, by the end of 2014, Xinjiang has reached 3 billion yuan of revenue, 2015, revenue is expected to double, the company valued at $ 10 billion. In 2014 the world UAV has sold 390,000, according to Shenzhen Customs figures showed, 2015 first five months of the year exports from Shenzhen drone to reach 160,000 units, were 69 times in the same period last year. Not long ago, billion aerial drone has released news of the $ 42 million b round of funding.
Some people think that the current UAV and RC airplane, RC airplane enthusiast is just a toy, or imaging enthusiasts to photograph "aircraft". Unmanned aerial vehicle how do you define it? what is the real meaning of the UAV? below, small give you a brief introduction:
Unmanned aerial vehicles are radio-controlled devices or own program control device for control of unmanned flight vehicle. Does not require drivers drive in the machine, and by remote control or automatic driving technologies for flight.
Model airplane is a heavier than air, there are size restrictions, but remote control cannot be manned aircraft. Can generally be divided into free flight class, line control categories, such as radio remote control.
Although drones and RC airplane is manned aerial vehicles, but they still have differences.
Task loading
UAV payload is an important component of UAV, unmanned aerial vehicle by mounting a variety of loads to achieve their objectives and tasks.
In terms of remote control and remote indexes of different drones may be automatically default to global, and RC airplane is within the range or radius of a few kilometers.
In the area of automatic control, UAV intelligently respond to various situations, called for a mandate, and the ground station for data integration and task confirmation, and called proceeding, and control most models can only be achieved automatically after a runaway to return home.
But for experienced RC airplane enthusiast, as long as the install task effectively "load", to bring it under control, model aircraft fully capable UAV's role.
This is not fantasy, Ardupilot is a popular DIY drone projects, using the Arduino platform for the development of autonomous driving systems, real people to drone operations. Shun Feng have been testing the waters and Amazon, UAV courier business.
Purpose use
Early UAV used in war, to perform military tasks, with the development of science and technology, the more extensive use of drones in civil, such as forest fire prevention, border enforcement, highway patrol, and prospecting application areas. Starting from the 70 s of a robot family context
Models focused on aviation model sport, RC airplane enthusiasts participating in ISF competitions, communication research, and so on.
Flight control system
Drone can fly autonomous driving, over the horizon, through a complex central control system, interacting with the ground control parameters, controlling aircraft attitude, and motor are controlled.
RC airplane is unmanned, but manipulated within the Visual range of hands in the control remote control implementation maneuver and attitude adjustment.
However, in some high end RC airplane systems, also can realize the automatic return function, beyond-visual-flight intelligent actions. For now, the development level of artificial intelligence, drones and airplanes can't shake off the dependence on people.
Safety management
At present, the RC airplane is mainly managed by the National Sports Commission under the air sports management center, unmanned aerial vehicles are managed by the Civil Aviation Administration of China.
Clear model management policy and responsibility, but the lack of clearly defined for airplanes and drones, made between the civil aviation authority and the Sports Authority's responsibility may not be so clear.
Aviation security management better United States, United States Federal Aviation Administration (FAA) unmanned aerial vehicles are divided into three categories: as public aircraft drone; as a civil aircraft and drones; and as model aircraft and drones.
Model airplane that satisfies the following criteria, and does not belong to the category of drone:
With a capacity for sustained flight in the atmosphere;
Planes are purely for the purposes of entertainment or hobby to run;
In the operator's line of sight operation;
Model aircraft flying within five miles of the airport shall notify the airports and the air traffic control tower;
Model aircraft shall not interfere with aircraft operation.
Meet five requirements to prove that it does not belong to the drones, so as to exempt future UAV developed by FAA airworthiness regulations approval.
