A tail seat ducted UAV

Abstract

The invention discloses a tailstock-type ducted unmanned aerial vehicle, which comprises a fuselage, two wings and two vertical tails, a total of four wings; the two wings are symmetrical left and right, and the vertical tails are symmetrically installed on On the fuselage, the fuselage is upright through four wing tips; the fuselage includes a nacelle and an engine seat, the lower part of the nacelle is connected to the engine seat, and an air inlet is formed between the periphery of the nacelle and the engine seat; the engine A ducted motor is installed on the inner side of the tail of the seat; four rudder surfaces are arranged at the ducted nozzle of the ducted motor, which are respectively fixed on the four wings, and the pitch, roll and yaw. The unmanned aerial vehicle of the present invention has simple structure and excellent comprehensive performance, can realize vertical take-off and landing, hovering, high-speed cruising and can load different loads, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a tail seat type ducted unmanned aerial vehicle. Background technique [0002] UAVs are widely used in aerial photography, agriculture, plant protection, selfie, express transportation, disaster rescue, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting and other fields. , which represents an important development direction of future aircraft. [0003] At present, there are two types of UAVs that can hover: (1) rotorcraft. Such as helicopters, quadrotors, etc. It adopts a completely different working form from the fixed wing. Compared with the fixed wing, it consumes more power and has a shorter time to stay in the air. It cannot cruise at high speed in a wide range like the fixed wing. (2) 3D machine. It adopts fixed-wing conventional layout, conventiona...

AI Technical Summary

Problems solved by technology

Fixed-wing conventional layout, conventional take-off and landing, propeller structure, slow level flight speed, generally unable to install load

[0004] At present, there is another type of ducted UAV: ​​it is mainly like a real machine, which can fly at high speed and has full power, but most of them cannot take off and land vertically. Very few models imitate vertical takeoff and landing fighters, and add extra power ( That is, there are different power sources for take-off, landing and level flight), the principle is similar to that of a rotorcraft, and the structure is complex

[0005] It can be seen that the above-mentioned existing unmanned aerial vehicle obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
