Technical Field

[0001] This utility model relates to the field of aircraft wing technology, and in particular to an expandable wing module. Background Technology

[0002] The wing is an important component of a fixed-wing aircraft. In previous designs, the wing primarily provided lift for the aircraft during cruise flight.

[0003] With the continuous advancement of technology, more and more aircraft with diverse functions are emerging. To meet the design needs of aircraft with different functions, engineers have proposed a variety of detachable and combinable aircraft wings.

[0004] Chinese patent application number "CN201821172033.4" proposes a quick-release wing and unmanned aerial vehicle, which uses a plug-in structure to detachably combine a part of the wing with another fixed wing.

[0005] Chinese patent application number "CN201821783870.0" proposes a modular wing for unmanned aerial vehicles (UAVs). The modular wing design connects multiple wing sub-modules together through identical "multiple sets of module interfaces" on both sides.

[0006] The existing modular wing design has poor wind resistance performance of its frame. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this invention is to provide an expandable wing module with a high-strength wing frame.

[0008] The present invention is implemented using the following scheme: an expandable wing module, including a module frame and a skin, the skin covering the module frame, the skin having a gap in the middle of the module frame to form a lift duct, the module frame including a leading edge keel, side panels and a trailing edge panel, a side panel being connected to each side of the leading edge keel, and several trailing edge panels being mounted between two side panels, the leading edge keel, side panels and trailing edge panels forming a U-shaped module frame along the lift duct; quick-release pins for connecting other module frames are also provided on the outer side of the side panels.

[0009] Preferably, the module frame is further provided with a first support rod sleeve and a second support rod sleeve. The first support rod sleeve is inserted into the front edge keel and two side wall plates, and the second support rod sleeve is inserted into the two side wall plates and several rear edge plates.

[0010] Preferably, the front part of the leading edge keel is an arc-shaped plate, and the rear part of the trailing edge plate is an acute-angled plate.

[0011] Preferably, a duct support plate is also provided parallel to the inner side of the side wall panel.

[0012] Preferably, the diameter of the first support rod sleeve is larger than the diameter of the second support rod sleeve, and a support rod can be inserted into both the first and second support rod sleeves. When multiple wing modules are connected, the support rods connect multiple wing modules in series.

[0013] Preferably, the quick-release pin includes a pin block and a pin buckle, the pin block being welded to the outside of the side wall panel, and the pin buckle being detachably mounted on the pin block.

[0014] The beneficial effects of this utility model are as follows: This utility model constructs a U-shaped modular skeleton by setting a leading-edge keel, side panels, and a trailing-edge plate. The leading-edge keel is used to bear wind loads, the side panels on both sides are used for support and connection with other wing modules, and the trailing-edge plate is an acute-angled plate that simulates the trailing-edge cross-section of an airfoil. This design places the main load-bearing skeleton as externally as possible, enhancing the structural strength of the wing module while maximizing the internal space of the wing module.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1 to 4An expandable wing module includes a module frame 1 and a skin 2. The skin 2 covers the module frame 1, and the skin 2 has a gap in the middle of the module frame 1 to form a lift duct 3. The module frame 1 includes a leading edge keel 11, side wall panels 12, and a trailing edge panel 13. A side wall panel 12 is connected to each side of the leading edge keel 11, and several trailing edge panels 13 are mounted between two side wall panels 12. The leading edge keel 11, side wall panels 12, and trailing edge panels 13 form a U-shaped module frame 1 along the lift duct 3. The outer side of the side wall panel 12 is also provided with quick-release pins 10 for connecting to other module frames 1.

[0022] This invention utilizes a U-shaped modular frame 1 constructed from a leading-edge keel 11, sidewall panels 12, and a trailing-edge panel 13. The leading-edge keel 11 bears the wind load, the sidewall panels 12 provide support and connect to other wing modules, and the trailing-edge panel 13 is an acute-angled plate simulating the trailing-edge cross-section of a wing. This design places the main load-bearing frame externally as much as possible, enhancing the structural strength of the wing module while maximizing the internal space. This prepares the wing module for the subsequent installation of more functional modules.

[0023] The module frame 1 is also equipped with a first support rod sleeve 4 and a second support rod sleeve 5. The first support rod sleeve 4 is inserted on the front edge keel 11 and two side wall plates 12, and the second support rod sleeve 5 is inserted on the two side wall plates 12 and several rear edge plates 13.

[0024] By welding the front edge keel 11, side wall plate 12, and rear edge plate 13 onto the first support rod sleeve 4 and the second support rod sleeve 5, the overall structural strength is further enhanced by utilizing the first support rod sleeve 4 and the second support rod sleeve 5.

[0025] The front part of the leading edge keel 11 is an arc-shaped plate, and the rear part of the trailing edge plate 13 is an acute-angled plate.

[0026] A duct support plate 14 is also arranged parallel to the inner side of the side wall panel 12. The duct support plate 14 further enhances the support of the frame structure for the fuselage skin, and duct support plates 14 at different positions can be set to adjust the position of the lift duct 3.

[0027] The diameter of the first support rod sleeve 4 is larger than the diameter of the second support rod sleeve 5. A support rod 45 can be inserted into both the first support rod sleeve 4 and the second support rod sleeve 5. When multiple wing modules are connected, the support rod 45 connects the multiple wing modules in series. The support rod 45 is used to bear the force between the multiple wing modules.

[0028] The quick-release pin 10 includes a pin block 101 and a pin 102. The pin block 101 is welded to the outside of the side wall plate 12, and the pin 102 is detachably mounted on the pin block 101.
