A century ago, human has been achieved aerial refueling technology, to put it simply, it is s technology that a jet aircraft reveres another one or several spacecraft or helicopter in the air, which can make its range increased, life growing. The technology applied in military field at the earliest.
With the rapid development of UAV in recent years, UAV has been widely used in military and civilian fields, especially in the field of civil, for example, UAV is used for to herd cattle, the crowd control. But there is an obvious obstacle hindering their progress, most of the drones are faced with a limited range.
Recently, a researcher of New Zealand came up with a docking system, which is able to change this dilemma faced by the UAV. Daniel Wilson, a researcher in he field of robot research center at the university of Sydney in Australia, he has developed a way to make the UAV docking in midair and supply, as many military aircraft approach used at the moment. He believed that the system which developed successfully by his team last November is the world’s first docking system designed for unmanned aerial vehicles. But last week, the U.S. navy’s X – 47B drone conducted a very successful experiment, become the world’s first UAV to refuel in the air.
Wilson said, their team used a drones which highly improved by themselves conduct a test, the experiment of fixed-wing UAV in the experiment can achieve an hour battery life. A scientists team at the university of Sydney has spent years to develop this technology, the docking system allows drones in the air according to the demand for refueling or recharging when docking.
The principle of this system can successfully run mainly relies on the GPS, inertial of highly coordinated motion sensors and two drones that upload some infrared technology–a pilot and a following UAV, two aircraft fuel or power transmission needs to be a “go” tube.
Navigation of unmanned opportunity dragged a conical ‘refueling’ tube, and the outward transfer of its on-board sensor data. Using this data, with no chance to try to following the pilot UAV, and flight to the accurate position. Once ready, the UAV will use the aircraft nose cone and the “Go” docking tube finalize aerial refueling or recharging.
According to the Wilson’s argument, trying to accurate finish stage is very difficult, especially because the two drones and fuel hose is very light in weight, will be affected by the wind and turbulence. So in a short time, the system is more likely to give large military UAVs for refueling, as for consumer drones, or fly back change the battery.
