Specialists from the Moscow Border Institute have developed a revolutionary multi-rotor drone with the ability to recharge directly during flight. Energy will be provided by the airflow from the propellers.

An air intake is placed in the center of the multicopter frame. The airflow from the propellers enters inside and spins a impeller, mounted on the shaft of an electric generator. The generated energy is directed back to the battery through the control system.

An additional energy source is a solar panel, applied to the protective cover of the upper part of the device. Swiveling nozzles are located under the frame. Their position is changed by two double solenoids, deflecting the outgoing flow in the desired direction.

The resulting reactive force should help control the device, increase speed, and reduce energy consumption for flight.

The payload is placed at the bottom so that it does not interfere with the operation of the nozzles. The patent lists observation, control, retransmission, and other applications among possible tasks.
