Problems solved by technology

[0002] The structure of the existing fixed-wing unmanned aircraft basically adopts the low-level tail installation mode. Because the airflow passes through the wings, the turbulence generated by the tail is relatively large, which limits the flight stability of the aircraft during operation.

Embodiment Construction

[0012] Such as figure 1 As shown, the fixed-wing aircraft provided by the present invention is assembled by engine 1, propeller 2, landing gear 3, wing 4, fuselage 5, vertical empennage 6, horizontal empennage 7, cabin 8. Described vertical empennage 6 is arranged on described fuselage 5 rear ends, and is positioned at the horizontal center line of described fuselage 5 rear ends, and the both sides of described vertical empennage 6 tops are symmetrically provided with described horizontal empennage 7, so Said horizontal stabilizer 7 is a high level tail.

[0013] Further, the landing gear 3 is a tricycle landing gear.

[0014] The structure of this unmanned fixed-wing aircraft uses a high-flat tail to improve the deep stall performance of the aircraft. The horizontal tail effectively avoids the turbulence of the wings, thus ensuring the stability of the aircraft. The fuselage adopts a large structure design, so that the structure of each part of the cabin is correspondingly ...

Abstract

The invention relates to a fixed wing type unmanned aerial vehicle belonging to the technical field of an unmanned aerial vehicle. With the adoption of the high and flat empennage, the deep stall performance of the aerial vehicle can be improved; the turbulent flow of the wing can be effectively avoided through the horizontal empennage, so that the stability of the aerial vehicle can be ensured. The fuselage adopts the large structure design, so that each component of the cabinet is structurally enlarged. Therefore, the aerial vehicle can bear more equipment and instruments; correspondingly, the endurance of the aerial vehicle is prolonged by adding an oil material amount, so that the operation time of the aerial vehicle is enough; the aerial vehicle is relatively stable in a landing run process through a front-three-point type undercarriage.

Description

technical field [0001] The invention belongs to the technical field of unmanned aircraft, in particular to a fixed-wing unmanned aircraft. Background technique [0002] The structure of the existing fixed-wing unmanned aircraft basically adopts the low-level tail installation mode. Because the airflow passes through the wings, the turbulence generated by the tail is relatively large, thus limiting the route stability of the aircraft during operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixed-wing unmanned aircraft, which can ensure a stable route and further ensure the effect of aerial photography. [0004] The invention provides a fixed-wing unmanned aircraft, comprising a propeller, an engine, a landing gear, a wing, a fuselage, and a cabin, the propeller is located at the front of the fuselage, and the wings are symmetrically arranged on both sides of the fuselage. It includes a vertical empenna...
