drone is an english word that means "drone", in the literal translation into Portuguese. However, this term has become popular worldwide to designate any type of unmanned aircraft, but commanded by humans from a distance.
In Portuguese, the drones can also be called UAV ("Unmanned Air Vehicle") or VARP ("Remotely Piloted Air Vehicle"), acronyms that were created from English Unmanned Aerial Vehicle - UAV.
Originally, the drones were designed for military purposes, to act in environments or situations of extreme danger to human beings, such as combat aircraft, reconnaissance in enemy territory or searches in places contaminated with toxic substances that would be lethal to humans.
You drones, in practice, are equipment that use a technology similar to those of classic remote control vehicles. They are produced with resistant materials and controlled remotely through satellite or radio signals.
The equipment's popularity grew towards the end of the first decade of the 21st century, when the drones
began to be widely used by civilians for entertainment purposes. Photographers and cameramen, for example, use drones with a camera attached to be able to take images from aerial angles.For military forces, the use of drones, in addition to being more efficient, it becomes much cheaper. It is estimated that the production of an unmanned aerial vehicle will cost the United States - one of the biggest investors in this technology - between US$ 800,000 and US$ 1 million, while conventional fighters would cost around US$ 65 million for the Armed Forces North American.
Drone in Brazil
The first Brazilian drone was registered as BQM1BR, a UAV prototype that works with jet propulsion, and which flew for the first time in 1983.
However, investments in drone technology in Brazil only gained strength from the year 2000, with the launch of the Arara Project (Autonomous and Remotely Assisted Reconnaissance Aircraft), with the purpose of reaching the market civil.
Currently, the Brazilian Federal Police have drones that guard the country's borders.
The technology was also used to broadcast the 2014 World Cup games through aerial images, and in the 2016 Olympics, with the same purpose.
