British uav wireless power technology being developed: to replace batteries coil
Most multiaxial unmanned aerial vehicle (uav) based on onboard battery, the single life is usually difficult to more than 30 minutes after charging, which greatly restricts their ability. Although can be energy delivery through cable, but this is only applicable to suspension to observe such as small scale application. However, scientists at imperial college London, has developed a no batteries and a new type of unmanned aerial vehicle (uav) power cable, because it can fly in the air intake wireless energy.
The study is based on a ready-made mini vehicle four axis, but removed on the battery, and give it put on a layer of copper coils.
In addition, the researchers created a separate wireless power transmission platform, copper coils, on the other hand, as the magnetic field on the receiving antenna (alternating current) can be produced, for unmanned aerial vehicle (uav) after rectification to dc power supply.
The official name of this technology as "inductive coupling" (inductive coupling), during the period of nikola tesla has been developed.
Imperial college, said it was the first time they provide wireless energy for unmanned aircraft in flight. Though it is only applicable to 10 cm (3.9 inches), but the future is expected to greatly expand its application range., of course, in addition to the flight of uav wireless power supply, this technique can also be for the onboard battery charging, to extend the flight landing (without charging/battery).
