Description

Technical Field

[0001] The utility model relates to the field of aircraft wing structures, in particular to a wing with an embedded power module. Background Technique

[0002] A vertical takeoff and landing aircraft generally refers to a type of aircraft that can take off and land vertically like a helicopter, has the ability to hover, and can fly horizontally in the manner of a fixed-wing aircraft. Benefiting from the advantages of convenient takeoff and landing and high flight efficiency, vertical takeoff and landing aircraft have important application values in the military. There are three types of vertical takeoff and landing aircraft: rotor-type vertical takeoff and landing aircraft, tilt-type vertical takeoff and landing aircraft, and tail-sitting vertical takeoff and landing aircraft.

[0003] With the development of vertical takeoff and landing aircraft, the designs for the power modules of vertical takeoff and landing aircraft have increased accordingly. Among them, setting the power module at the edge of the aircraft wing is one of the trends.

[0004] The Chinese patent with the patent number 2022202286766 proposed an electric ducted fan and an electric vertical takeoff and landing hybrid-wing small manned aircraft, which set the tilt ducted fan in a semi-circular vacancy opened on the trailing edge of the wing.

[0005] At the same time, the TriFan 200 (cargo) product proposed by XTI Aircraft Company (website: www.xtiaircraft.com) set the tilt ducted fan in a semi-circular vacancy on the leading edge of the wing. This design can utilize the structure of the wing to install the ducted fan more safely, and the airflow generated by the ducted fan is organically combined with the wing to increase the flight stability.

[0006] However, as long as a rotatable ducted fan power is set on the aircraft wing, it is easy to affect the aerodynamic model of the aircraft, generate turbulence easily, and increase the aerodynamic drag of the aircraft.

[0007] In the existing designs for reducing the resistance of the ducted fan, such as the Chinese patent with the patent number 2017109119683, which proposed a dual-lift ducted vertical takeoff and landing aircraft based on a tilt ducted fan, and it covered the ducted fan by setting an openable baffle on the ducted fan. This method is not applicable to the ducted fan set at the wing edge. Summary of the Utility Model

[0008] To solve the above problems, the purpose of the utility model is to provide a wing with an embedded power module, which reduces the damage to the wing surface caused by the embedded power module and improves the aerodynamic efficiency.

[0009] The following solution is adopted in the embodiment of the present utility model: A wing with an embedded power module, including a wing body and a power module. An arc-shaped notch is formed on the trailing edge of the wing body. The power module is rotatably arranged in the arc-shaped notch to switch between a vertical take-off and landing mode in a horizontal state and a level flight and cruise mode in a vertical state.

[0010] A wing complement block is vertically connected to the power module. When the power module tilts from the vertical take-off and landing mode in the horizontal state to the level flight and cruise mode in the vertical state, the wing complement block rotates with the power module and fills the arc-shaped notch.

[0011] Preferably, two arc-shaped notches are symmetrically formed on the wing body along the wingspan extension direction. A power module is arranged in each arc-shaped notch. A tilt synchronization rod is buried inside the wing body, and a tilting device is also arranged in the middle of the wing body.

[0012] Both ends of the tilt synchronization rod are respectively connected to a power module. The tilting device is connected to the middle of the tilt synchronization rod. The tilting device rotates the tilt synchronization rod and drives the power module to tilt.

[0013] Preferably, the tilting device includes a power motor, a driving gear, and a driven gear. The power motor is mounted inside the wing body. The power motor is connected to and drives the driving gear. The driven gear is sleeved on the tilt synchronization rod, and the driving gear meshes with the driven gear.

[0014] Preferably, the power module includes a duct wall, a support plate, and a rotating fan. The duct wall is rotatably arranged in the arc-shaped notch. The support plate is erected inside the duct wall, and the rotating fan is installed on the support plate.

[0015] Preferably, the arc-shaped notch is formed on the outer side of the trailing edge of the wing body.

[0016] Preferably, the arc-shaped notch is formed in the middle of the trailing edge of the wing body.

[0017] The present utility model provides a wing with an embedded power module and an aircraft adopting the wing structure. Compared with the prior art, the present utility model has at least the following technical effects:

[0018] In this case, a wing complement block that rotates with the power module is innovatively designed. When the power module tilts forward from the horizontal state to the vertical state, the wing complement block vertically arranged on the power module tilts forward accordingly. The wing complement block fills to complete the arc-shaped notch on the wing body. It reduces the damage to the wing surface by the embedded duct wing and improves the aerodynamic efficiency. At the same time, it also reduces the noise of the wing body during flight. Description of the Drawings

Specific embodiments

[0027] The following further describes the present utility model with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figures 1 to 7 , a wing with an embedded power module, including a main wing body 1 and a power module 2. An arc-shaped notch 4 is formed on the trailing edge 3 of the main wing body 1. The power module 2 is rotatably arranged in the arc-shaped notch 4 to switch between a vertical take-off and landing mode in a horizontal state and a level flight and cruise mode in a vertical state;

[0029] A wing completion block 5 is vertically connected to the power module 2. When the power module 2 tilts from the vertical take-off and landing mode in the horizontal state to the level flight and cruise mode in the vertical state, the wing completion block 5 rotates with the power module 2 and fills the arc-shaped notch 4.

[0030] The advantage of designing the power module 2 at the trailing edge 3 of the main wing body 1 adopted in the present utility model is that the force transmission route is more optimal and the influence on the main torsion-resistant components of the wing is reduced. Compared with the wing structure with the power module 2 arranged at the leading edge 30, the structure is simpler and more reliable.

[0031] Moreover, in order to further reduce the increase in drag caused by the arc-shaped notch 4 opened at the trailing edge 3 of the wing body 1, the present case innovatively designs a wing complementing block 5 that flips with the power module 2. When the power module 2 tilts forward from the horizontal state to the vertical state, the wing complementing block 5 vertically arranged on the power module 2 flips forward accordingly. The wing complementing block 5 fills to complement the arc-shaped notch 4 on the wing body 1. This reduces the damage to the wing surface by the embedded ducted wing and improves the aerodynamic efficiency. At the same time, it also reduces the noise of the wing body 1 during flight.

[0032] The power module 2 with the wing complementing block 5 arranged on the wing body 1 can be adjusted in quantity according to the power required by the wing. In the present case, two arc-shaped notches 4 are symmetrically opened on the wing body 1 along the spanwise extension direction, and one power module 2 is arranged in each arc-shaped notch 4. Antilateral rotation synchronizing rod 11 is buried inside the wing body 1, and antilateral rotation device 6 is also arranged in the middle of the wing body 1;

[0033] Both ends of the antilateral rotation synchronizing rod 11 are respectively connected to a power module 2, and the antilateral rotation device 6 is connected to the middle of the antilateral rotation synchronizing rod 11. The antilateral rotation device 6 rotates the antilateral rotation synchronizing rod 11 and drives the power module 2 to tilt. In addition, two fan power modules providing vertical lift are symmetrically arranged on the wing body 1.

[0034] The structure of the antilateral rotation device 6 can be various. In the present case, the antilateral rotation device 6 includes a power motor 61, a driving gear 62, and a driven gear 63. The power motor 61 is mounted inside the wing body 1. The power motor 61 is connected to and drives the driving gear 62. The driven gear 63 is sleeved on the antilateral rotation synchronizing rod 11, and the driving gear 62 meshes with the driven gear 63. In addition, the antilateral rotation device 6 can also adopt various driving designs such as hydraulic pressure, connecting rod, and electromagnetic, etc. However, the main purpose of providing tilting remains unchanged.

[0035] The power module 2 includes a duct wall 21, a support plate 22, and a rotating fan 23. The duct wall 21 is rotatably arranged in the arc-shaped notch 4. The support plate 22 is mounted inside the duct wall 21, and the rotating fan 23 is installed on the support plate 22.

[0036] The installation position of the arc-shaped notch 4 on the wing body 1 can be various. The arc-shaped notch 4 can be opened on the outer side of the trailing edge 3 of the wing body 1. The arc-shaped notch 4 can also be opened in the middle of the trailing edge 3 of the wing body 1.

[0037] Moreover, the shape of the arc-shaped notch 4 is for installing the power module 2 and partially accommodating the power module 2.

[0038] An aircraft includes a fuselage 100, and the fuselage 100 is provided with the wing with the embedded power module as described above. This is the specific application of the present utility model.

[0039] In the present utility model, two groups of wings with embedded power modules are arranged in parallel on the body 100. Among them, for the wing arranged at the head of the body 100, the installation notch 4 is opened on the outer side of the trailing edge 3 of the wing main body 1; for the wing arranged at the tail of the body 100, the installation notch 4 is opened in the middle of the trailing edge 3 of the wing main body 1. Such a wing design is to enable the power module 2 in the wing main body 1 at the tail to utilize the airflow generated by the power module 2 in the wing main body 1 at the head, thereby further improving the flight efficiency of the wing.
