Technical Field

[0001] The present application relates to the field of target drone wing structures, and in particular to a target drone water recovery sealed wing. Background Art

[0002] A target drone is a military aircraft used as a target for shooting training. This aircraft uses remote control or a pre-set flight path to simulate enemy aircraft or incoming missiles during military exercises or weapon tests. In order to reduce the overall weight of the target drone, the wings of the target drone need to be designed to be lightweight.

[0003] The relevant target aircraft wing includes a wing panel, a skin and a sealant layer. A cavity is opened in the middle of the wing panel, and a reinforcement plate frame is arranged in the cavity. The reinforcement plate frame is fixed on the wing panel. The sealant layer is arranged between the skin and the wing panel, and the skin is bonded and fixed to the surface of the wing panel, so that the wing of the target aircraft maintains a smooth surface and has a better starting shape.

[0004] The above-mentioned related technical solutions have the following defects: when the target drone completes training and lands on the water, water is likely to remain in the cavity of the wing panel after the target drone is recovered, making the subsequent cleaning of the target drone time-consuming and laborious. Utility Model Content

[0005] In order to facilitate the cleaning of the accumulated water in the wing panel of the target aircraft, the present application provides a sealed wing for the target aircraft to be recovered on water.

[0008] By adopting the above technical scheme, a cavity is opened in the middle of the wing panel to reduce the overall weight of the wing panel, and a skin is bonded to the wing panel to make the target aircraft wing have a better aerodynamic shape. By detachably connecting a drainage mechanism to the skin, when the user recovers the target aircraft from the water surface, the drainage mechanism can be removed from the skin, thereby allowing the accumulated water in the cavity of the wing panel to flow out, thereby facilitating the cleaning of the accumulated water in the wing panel of the target aircraft.

[0009] Optionally, the drainage mechanism includes a mounting piece and a stud, the mounting piece is a threaded cylinder structure, the mounting piece is fixed to the inner side of the skin, and the stud is threadedly connected in the mounting piece.

[0010] By adopting the above technical scheme, by installing a mounting piece on the skin, the stud is threadedly connected to the skin through the mounting piece, so that the area of ​​the threaded connection between the stud and the mounting piece is larger and the connection stability is higher. By arranging the mounting piece in the cavity, the mounting piece and the stud can be arranged in the cavity of the wing panel, thereby keeping the skin surface smooth and giving the target aircraft a better aerodynamic shape.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a target drone water recovery sealed wing, referring to Figure 1 and Figure 2 , including a wing panel 1, a skin 2 and a sealant layer 3. A cavity 12 is provided in the middle of the wing panel 1. The wing panel 1 is a frame structure. A plurality of reinforcing plate frames 11 are provided in the cavity 12. The reinforcing plate frames 11 are fixed in the cavity 12. The skin 2 is provided on both sides of the wing panel 1. The sealant layer 3 is provided between the wing panel 1 and the skin 2. The sealant layer 3 is used to bond the wing panel 1 and the skin 2. When the target drone is flying, the wing panel 1 bears stress and supports the flight of the target drone. By providing the cavity 12 in the wing panel 1, the cavity 12 can reduce the weight of the wing panel 1 and reduce the fuel consumption of the target drone during flight. The skin 2 makes the surface of the wing panel 1 smooth and improves the stability of the target drone during flight. The sealant layer 3 has good waterproofness. When the target drone lands on the water surface, it can reduce the probability of water entering the cavity 12, thereby maintaining a good structural strength of the wing panel 1 and improving the number of times the target drone can be recovered.

[0033] Reference Figure 1 and Figure 3 , a drainage mechanism 4 is provided on the skin 2. In other embodiments, a cavity 12 is provided in the wing panel 1, and the cavity 12 is a blind groove. The drainage mechanism 4 is installed on the wing panel 1 and is located at the bottom of the cavity 12. The drainage mechanism 4 includes a mounting member 41 and a stud 42. The mounting member 41 is fixed on the inner surface of the skin 2. An opening is provided on the skin 2. The stud 42 is inserted into the opening and connected to the mounting member 41. The mounting member 41 is configured as a cylindrical structure with an internal thread, and the mounting member 41 is threadedly connected to the stud 42. When the sealing performance of the sealant layer 3 decreases, water is easily stored in the wing panel 1 after the target drone is recovered on the water surface. The user can remove the stud 42 to allow the water in the cavity 12 to flow out, thereby reducing the erosion of the wing panel 1 by water and improving the service life of the wing panel 1.

[0034] Reference Figure 1 and Figure 3 A plurality of clearance holes 411 are provided on the side wall of the mounting member 41. The clearance holes 411 are provided at equal intervals along the circumferential direction of the mounting member 41, and the clearance holes 411 penetrate the mounting member 41. When water accumulates in the cavity 12, the accumulated water can flow out through the clearance holes 411. The area of ​​the threaded connection portion between the mounting member 41 and the stud 42 is large, which can reduce the probability of the stud 42 and the mounting member 41 being disconnected during the flight of the target drone.

[0035] Reference Figure 1 and Figure 3The upper end of the stud 42 is provided with a clamping member 421, which is a circular plate structure and is coaxially connected to the stud 42. When the stud 42 is connected to the mounting member 41, the clamping member 421 is located in the cavity 12. The clamping member 421 is used to clamp on the mounting member 41. When a slip occurs between the mounting member 41 and the stud 42, the clamping member 421 can be clamped on the mounting member 41, so that the stud 42 is difficult to fall off from the skin 2.

[0036] Reference Figure 1 and Figure 3 A semi-spherical part 422 is provided at one end of the stud 42 away from the clamp 421, and the end face of the semi-spherical part 422 is connected to the end face of the stud 42. When the stud 42 is connected to the mounting part 41 and blocks the clearance hole 411, the semi-spherical part 422 is located on the surface of the skin 2. The semi-spherical part 422 is used to keep the surface of the skin 2 in a better aerodynamic shape. According to the flight data and effect of the target drone, the semi-spherical part 422 can be set to an ellipsoidal sphere or an arc surface.

[0037] Reference Figure 1 and Figure 3 A connecting groove 423 is provided in the middle of the semi-spherical part 422. The connecting groove 423 can be provided as a straight groove, and the user can insert a screwdriver into the connecting groove 423, thereby facilitating the screwing of the stud 42. When the user screws the stud 42, the stud 42 extends into the cavity 12 of the wing panel 1, so that the clearance hole 411 connects the inner and outer sides of the wing panel 1, so that the accumulated water in the cavity 12 can flow out.

[0038] Reference Figure 1 and Figure 3 The reinforcement plate frame 11 is provided with a plurality of drainage holes 111, which penetrate the reinforcement plate frame 11. The reinforcement plate frame 11 divides the cavity 12 into a plurality of spaces that are not connected to each other. When the accumulated water is distributed in the cavity 12, the accumulated water can flow along the curved arc of the skin 2 and flow to the drainage mechanism 4 through the drainage holes 111. When the user screws the stud 42, the accumulated water in the cavity 12 can flow out completely, reducing the steps for the user to shake the target drone.

[0039] The implementation principle of the embodiment of the present application is as follows: by opening a cavity 12 on the wing panel 1, the weight of the wing panel 1 is reduced; by arranging a skin 2 on the surface of the wing panel 1, the surface of the skin 2 is smooth and covers the wing panel 1, so that the wing panel 1 has a better aerodynamic shape; by arranging a mounting member 41 on the skin 2, a detachable connecting stud 42 is provided on the mounting member 41, so that the stud 42 can be threadedly connected in the mounting member 41 and block the clearance hole 411, the target aircraft can remain stable during flight, and when the target aircraft lands on the water, water is easily accumulated in the cavity 12 of the wing panel 1. The user can move the stud 42 along the length direction of the mounting member 41 by screwing the stud 42, so that the clearance hole 411 is exposed, and the accumulated water in the wing panel 1 flows out, thereby reducing the erosion of the wing panel 1 by the accumulated water.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
