FIELD: aerial vehicles.

SUBSTANCE: unmanned aerial vehicle contains a fuselage consisting of a single central body, a bearing surface consisting of a front wing (104), a rear wing (109), a propulsion system powered by electric batteries and photocells that cover the upper outer surfaces of the front wing and rear wing. The rear wing is offset in height and length on the fuselage relative to the front wing. The front wing (104) and the rear wing (109) are straight wings. The front wing is directly attached to the lower level of the central body, projecting from this central body, and is characterized by a zero lateral V angle. The rear wing is directly attached to the upper level of the central body, projecting from this central body, and is characterized by a positive transverse V. The front wing is substantially equal to the surface area of ​​the rear wing.

EFFECT: invention is aimed at optimizing the aerodynamic characteristics.
