FIELD: aircraft engineering.
SUBSTANCE: invention relates to the field of aviation, in particular to the design of unmanned aerial vehicles. Proposed unmanned aerial vehicle represents a tandem aerodynamic design and comprises fuselage (4) with wings supporting rotors (1) and thrust source (5). Front (2) and rear (3) wings are arranged on fuselage (4) with rear wing (3) shifted upward and backward relative to front wing (2). Rotors (1) are located under wings plane. Ratio of rotor swept area to wing area makes 1.9 to 2.2. Rotor plane angle (8) varies from -7 to -15 degrees relative to aircraft building line (6). Rotor plane angle (8) does not vary in flight.
EFFECT: increase in vertical thrust during takeoff and lifting capacity.
