Unmanned aerial vehicle capable of patrolling with long endurance, wide speed range and high mobility

Abstract

The invention provides an unmanned aerial vehicle capable of patrolling with long endurance, wide speed range and high mobility. The unmanned aerial vehicle mainly comprises a fuselage, a pair of foldable inner wing sections arranged on the two sides of the fuselage, outer wing sections which are telescopic in the spanwise direction, a pair of foldable upper V-shaped empennages arranged at the tail of the fuselage, and a pair of foldable ventral fins, and a power unit at the tail of the fuselage. The two changeable foldable wings on the two sides of the fuselage can rotate in the planes of thewings according to the use requirements, so as to realize the functions of folding and changing backswept wings; the outer wing sections which are telescopic in the spanwise direction assists in increasing the aspect ratio of the wing; the pair of foldable upper V-shaped empennages at the tail of the fuselage and the pair of foldable ventral fins are used to improve the maneuverability and have low resistance characteristics compared with conventional empennages; and the power unit is mounted at the rear section of the fuselage, and a turbojet power, piston power and turbojet / piston dual power unit can be optionally mounted to enable the unmanned aerial vehicle to fly efficiently and stably. The change of the position of the foldable wings at different speeds, the outer wing sections which are telescopic in the spanwise direction, the foldable upper V-shaped empennages, the foldable ventral fins and the tail power unit of the fuselage jointly improve the adaptability of the unmanned aerial vehicle at different speeds.

Description

technical field [0001] Embodiments of the present invention relate to aircraft technology, and in particular to an unmanned aerial vehicle capable of long-endurance, wide-speed range, and high-mobility cruising. Background technique [0002] The roving unmanned aerial vehicle is a new concept aircraft that can perform patrol flights in the target area and perform various tasks such as reconnaissance, strike, communication, and relay. At present, in order to meet its comprehensive mission performance and consider the variability of the external environment, the cruising UAV should have the characteristics of high maneuverability, rapid arrival and strike, and long endurance. Conventional roving unmanned aerial vehicles often can only meet one of the above-mentioned performances, but cannot take into account both high-speed and low-speed performance requirements. Its flight missions usually have certain limitations, and it is impossible to adjust a reasonable attitude with th...
