Problems solved by technology

However, there are the following problems in the drones currently in use: 1. The fuselage cannot be adjusted, the overall structure is large, and it takes up a lot of space, so it is not suitable for carrying; if it is stored for carrying and disassembled before and after use; Lack of aerodynamic design, high flight resistance, and slow flight speed; lift completely depends on the thrust of the motor, resulting in a small horizontal component of the motor thrust and insufficient forward power; and the flight consumes a lot of power and has a short range; 3. There is no storage space in the fuselage, and hoisting is often used when transporting goods, which interferes with the center of gravity of the UAV, reduces maneuverability, increases resistance when hoisting, and has low economic benefits; 4. Traditional rotor UAVs lack redundant control capabilities , the rotor is exposed, which poses a safety hazard
[0003] Traditional rotary-wing UAVs have low flight time, slow speed, and great safety hazards, while traditional fixed-wing UAVs are not suitable for urban environments due to site restrictions.

Embodiment 2

[0066] The scheme of embodiment two and embodiment one is basically the same, and its difference is: as Figure 8 As shown, the cross-sectional shape of the fuselage is a flat convex wing structure, that is, the top cover 4 protrudes upwards, and the bottom plate 2 is flat and straight except for the front edge. This kind of fuselage structure design is convenient for mass production.

Embodiment 3

[0068] The third embodiment is basically the same as the technical solution in the first embodiment, the difference is that both the vertical stabilizer and the horizontal stabilizer include a carbon fiber layer, and a radar wave-transmitting layer and a radar-absorbing layer are arranged on the surface of the carbon fiber layer and radar reflective layer.

[0069] Preferably, the radar absorbing layer is a polyimide film layer.

[0070] On the one hand, the bottom layer of the carbon fiber layer can prevent the UAV from being deformed and damaged when it encounters severe weather such as strong winds during flight. On the other hand, its light weight can reduce the weight of the UAV and make it easy to carry.

[0071] By setting the radar-transparent layer, radar-absorbing layer and radar-reflecting layer, the RCS of the UAV is reduced, which can make the UAV have the effect of radar stealth, and can realize reconnaissance or transportation operations without being noticed. ...

Embodiment 4

[0073] Embodiment 4 has basically the same technical solution as Embodiment 1, except that: both the vertical stabilizer and the horizontal stabilizer include a carbon fiber layer, and an infrared stealth coating is provided on the surface of the carbon fiber layer.

[0074] On the one hand, the bottom layer of the carbon fiber layer can prevent the UAV from being deformed and damaged when it encounters severe weather such as strong winds during flight. On the other hand, its light weight can reduce the weight of the UAV and make it easy to carry.

[0075] The design of the infrared stealth coating can make the drone have the effect of infrared stealth, and can realize reconnaissance or transportation operations without being noticed.

Abstract

The invention discloses a safe and stable novel transportation unmanned aerial vehicle. The safe and stable novel transportation unmanned aerial vehicle comprises a vehicle body, a rotor wing mechanism and an empennage mechanism. The vehicle body comprises a base plate, a left plate, a right plate and a top cover. The top cover and the base plate meet at the front and rear of the vehicle body andform a Clark Y wing-shaped structure with the relative thickness being 21%. The vehicle body comprises a middle vehicle body and a left vehicle body and a right vehicle body which are in sliding connection with the middle vehicle body. Tilt rotor wing design is adopted for the rotor wing mechanism. The rotor wing mechanism comprises a rotor wing body. The rotor wing body is arranged to be a pair of duct rotor wings symmetrically arranged on two sides of the vehicle body and relative fixing pieces and a steering engine and a tilt control rod which are used for controlling tilting action. The empennage mechanism comprises an installation bracket arranged below the rear portion of the vehicle body and an empennage body connected with the installation bracket and can rotate relative to the installation bracket. The safe and stable novel transportation unmanned aerial vehicle has the advantages that the flight speed is high, the flight distance is long, folding is achieved, and safety and stability are achieved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a safe and stable new transport unmanned aerial vehicle. Background technique [0002] With the development of modern logistics industry and drone technology, combined with the current situation of urban expansion and heavy traffic, drone transportation has attracted more and more attention from express companies and ordering platforms. UAV transportation has the advantages of wide transportation range, fast delivery speed, and not being restricted by traffic conditions. However, there are the following problems in the drones currently in use: 1. The fuselage cannot be adjusted, the overall structure is large, and it takes up a lot of space, so it is not suitable for carrying; if it is stored for carrying and disassembled before and after use; Lack of aerodynamic design, high flight resistance, and slow flight speed; lift completely depends on the th...
