UNMANNED AERIAL VEHICLE FOR DIAGNOSING HIGH-VOLTAGE ELECTRICAL INSTALLATIONS Russian patent published in 2023 - IPC B64C39/02 G01R31/08 

FIELD: unmanned aerial vehicle.

SUBSTANCE: invention relates to unmanned aerial vehicles and may be used for diagnosing high-voltage electrical installations. Simultaneously with the rotation of the outer hollow shafts (3), the inner shafts (29) rotate coaxial to the outer shafts, with rotation occurring in the opposite direction via transmission (30) actuation. The rotation of the auxiliary blades (31) results in the suction of supplementary air from the side. The rotating magnetic field of the permanent magnets (32) rigidly attached to the auxiliary blades (31) induces an additional electromotive force in the magnetic aerials (23), which increases the charging current of the battery (16) and allows charging even in the absence of an external magnetic field.

EFFECT: invention provides possibility to increase flight duration.
