Technical Field
[0001] This utility model relates to the field of aircraft technology, and more specifically, to a vertical tail structure for a fixed-wing aircraft. Background Technology
[0002] A fixed-wing aircraft, often simply called an airplane, is a heavier-than-air aircraft that flies within the atmosphere, propelled by a power unit that generates thrust or pull and lifted by fixed wings. It is one type of fixed-wing aircraft, and also the most common. Another type of fixed-wing aircraft is the glider. Aircraft can be further classified according to the type of engine they use: jet aircraft and propeller aircraft.
[0003] The existing vertical tail structure of fixed-wing aircraft suffers damage to its fuselage and vertical tail control surfaces when it hits the ground, grass, or tree branches. Furthermore, during ground taxiing or takeoff and landing, the rear wheel assembly bears the weight of the aircraft, causing damage to the fuselage and vertical tail control surfaces.
[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0007] A vertical tail structure for a fixed-wing aircraft includes a fuselage and a vertical tail control surface, and a hinge mount for connecting the fuselage and the vertical tail control surface. The top of the vertical tail control surface is provided with a top protection component. A vertical tail protection component is provided on the top of the fuselage near the top protection component. The vertical tail protection component and the top protection component are connected by screws. A lower vertical tail support is provided at the bottom of the vertical tail control surface. A rear wheel support is connected to the bottom of the lower vertical tail support, and a tail wheel is rotatably connected to the rear wheel support. A lower vertical tail mounting base is provided at the bottom of the fuselage near the vertical tail control surface.
[0008] Preferably, the machine body is provided with a hinge female seat that is adapted to and connected to the hinge male seat, and the hinge male seat and the hinge female seat adopt a semi-circular structure.
[0009] Preferably, the sidewall of the vertical tail rudder is provided with a rudder support block, which is connected to the vertical tail rudder by a screw.
[0010] Preferably, the rear wheel bracket is connected to the lower tail bracket via screw three.
[0011] Preferably, the bottom of the vertical tail control surface on the side away from the fuselage is provided with a control surface bottom protection component.
[0012] Preferably, screw one and screw two are used to fix the top protective part of the rudder surface and the rudder surface support block, and can also be used as movable parts for connection.
[0013] Preferably, a U-shaped groove is provided on the side of the fuselage near the vertical tail control surface, and a semi-circular structure on one side of the vertical tail control surface is adapted to the U-shaped groove.
[0014] The beneficial effects of this utility model are as follows: A complete set of vertical tail rudder surface hinges is formed by three structures: screw one and screw two arranged at the top and bottom, and the male and female hinge seats in the middle. This method makes assembly and disassembly very convenient; and the screws act as rotating hinges. In this case, the hinge strength is particularly high, and it can withstand the impact force brought about by the assembly of the tail wheel.
[0015] The top and bottom protective components of the control surfaces protect the fuselage and vertical tail control surfaces from damage when they hit the ground, grass, or tree branches.
[0016] The U-shaped groove fits snugly against the semi-circular vertical tail control surface, resulting in a smooth appearance and low flight drag. Attached Figure Description
