SMALL UNMANNED AERIAL VEHICLE Russian patent published in 2024 - IPC B64U20/50 

FIELD: aircraft engineering.

SUBSTANCE: small-sized unmanned aerial vehicle designed to transport a small payload at high subsonic speeds over a distance. In this case, the small-sized unmanned aerial vehicle contains a “tailless” aircraft-type airframe made of composite material, containing a fuselage and a swept-shaped wing. In this case, the wing is made either in the form of easily removable detachable parts with elevons and a vertical tail with rudders mounted on the wingtips, or in the form of parts that are permanently attached to the fuselage and have rotating parts with rudders located on the wingtips. In this case, the aircraft also contains an engine located behind the fuselage on an air intake spacer. The flight control device in the form of a flight navigation complex (FNC) includes an automatic control system that ensures flight according to programmed coordinates, carried out according to inertial system data and global navigation satellite system (GNSS) data, and also ensures autonomous flight, including in the absence of data from GNSS or data substitution (GNSS snuffing). In this case, an electrical control system is used to influence the control elements. The aircraft is also equipped with a parachute for landing.

EFFECT: high flight reliability and high loading factor.
