MOSCOW, Dec 25 - RIA Novosti. Specialists of the Tyumen Higher Military Engineering Command School named after Marshal of Engineering Troops Proshlyakov of the Ministry of Defense of the Russian Federation have developed a drone project that can be recharged from power lines, which significantly increases the duration of the flight of small drones, follows from a document published on the website of Rospatent.
According to the abstract of the invention, the proposed drone is a multicopter (an aircraft with several rotors), in the lower part of which an openable ring magnetic circuit is installed - current tongs with which the drone hooks onto the power line to recharge its battery.
Military scientists justify the feasibility of this project by the fact that currently Russian mini-drones are not capable of making long flights, while there is such a need both in peacetime and wartime, in particular for reconnaissance of enemy territory.
It is assumed that such a copter will work as follows: the remote operator of the drone directs its "pincers" to the power line and gives the command to close them. Then the drone is charged in an inverted position, while it retains the ability to conduct reconnaissance by turning the camera mounted on it in the right direction.
After charging the battery, the copter engines are started - and the "pincers" open the electrical wire, the drone returns to its original position and continues flying. The abstract notes that the placement of the magnetic circuit in the lower part of the drone on the axis of symmetry allows it to disconnect from the power line without risk (uncontrolled rotation).
According to the document, the drone's magnetic core can also be used to capture and dump its payloads with "pincers".
