High-stability double-tail-support vertical annular wing unmanned aerial vehicle

[0025] A high-stability double-tail vertical ring-wing unmanned aerial vehicle of the present invention, said high-stability double-tail vertical ring-wing UAV includes a fusion fuselage 1, a vertical ring-shaped wing 2, a double tail support 3. Vertical tail 4, horizontal tail 5, propeller propulsion system 6, control system 7.

[0026] The fusion fuselage 1 is placed in the middle of the lower elliptical wing 22 in a curved surface fusion manner, and can be used for infrared, photoelectric, medical equipment, emergency medicine, etc., and the payload is 8kg.

[0027] Described vertical annular wing 2 comprises upper oval wing 21 and lower oval wing 22, and upper oval wing 21 and lower oval wing 22 are connected to form annular wing 2 at wingtip; The elliptical wing 21 and the lower elliptical wing 22 adopt the NACA series 4-digit airfoil; the upper elliptical wing 21 can be swept forward, and the lower elliptical wing 22 can be swept back. The sweep angle is 5 degrees. The...

[0033] The difference between embodiment 2 and embodiment 1 is that: the payload weighs 15 kg; the NACA five-digit airfoil is adopted; the forward and backward sweep angles are 8 degrees.

[0034] The fusion fuselage 1 is placed in the middle of the lower elliptical wing 22 in a curved surface fusion manner, and the load is photoelectric detection equipment or aerial survey monitoring equipment, which is placed inside the fuselage, and the payload weighs 15 kg.

[0035] The upper elliptical wing 21 and the lower elliptical wing 22 of the vertical annular wing 2 adopt the NACA five-digit airfoil; The sweeping method is adopted, and the sweeping angle and the sweeping angle are 8 degrees.

[0036] The propeller 63 is installed on the rear end of the propulsion system driving device 62 and adopts 3 blades.

[0038]The difference between Embodiment 3 and Embodiment 1 is that the payload is 20 kg, the vertical ring-shaped wing adopts a laminar airfoil, the sweep angle and the sweep angle are 12 degrees, and the propulsion system support frame is arranged on the lower oval wing. 0.5 times the chord length.

[0039] The fusion fuselage 1 is placed in the middle of the lower elliptical wing 22 in a curved surface fusion manner, and the load is laser detection and testing equipment, which is placed inside the fuselage, and the payload weighs 20 kg.

[0040] The upper elliptical wing 21 and the lower elliptical wing 22 of the vertical annular wing 2 adopt the NACA laminar flow airfoil; Sweep way, the sweep angle and sweep angle are 12 degrees.

[0041] The propeller propulsion system 6 is composed of a propulsion system support frame 61, a propulsion system driving device 62 and a propeller 63, and the propulsion system support frame 61 is arranged at the rear end of the fusion type fus...
