Description

Technical Field

[0001] This utility model relates to the field of aerial refueling auxiliary devices for large unmanned aerial vehicles (UAVs), specifically, it is an aerial refueling auxiliary docking device. Background Technology

[0002] Existing autonomous docking aerial refueling probes require docking between the tanker and the receiver aircraft. The overall structure is complex and easily damaged in the variable environment at high altitudes, which can lead to refueling failure or even damage to the receiver aircraft, greatly increasing the risks of aerial refueling.

[0003] The existing aerial refueling probes for large drones have the following main drawbacks:

[0004] Hose-and-loop refueling systems are susceptible to interference from atmospheric turbulence, the tanker's wake, and aircraft vibrations, causing the hose to sway violently (i.e., "whiplash"). This swaying not only increases the difficulty of docking but can also cause the receiver propellant to break or even detach, seriously threatening flight safety. For example, when the receiver aircraft approaches the drogue, the drogue's sway can reach several meters, posing a significant challenge to flight attitude control. Therefore, this product optimizes the drogue structure to enhance longitudinal stability.

[0005] The receiver aircraft must maintain a precise relative position to the refueling aircraft, which places extremely high demands on the UAV's automatic control system. Furthermore, the unpredictable movement of the refueling hose needs to be tracked in real time by observation cameras, further increasing system complexity. Structural design also impacts flight performance; a fixed refueling probe increases the UAV's aerodynamic drag.

[0006] The core contradiction of existing large-scale drone refueling systems lies in the fact that flexible hose systems struggle to balance efficiency and safety, while rigid hose systems are limited by platform compatibility. Utility Model Content

[0007] The purpose of this invention is to provide an aerial refueling auxiliary docking device to solve the stability and control precision problems that aerial refueling pipes may encounter when flying in complex high-altitude environments.

[0008] To solve the above problems, the present invention adopts the following technical means:

[0009] An aerial refueling auxiliary docking device includes a first reinforcing ring and an adjustment mechanism arranged coaxially, wherein the first reinforcing ring and the adjustment mechanism are connected by a first connecting hose arranged around its axis.

[0010] The outer wall of the adjustment mechanism is provided with a tail fin, and the end of the tail fin facing away from the first reinforcing ring is provided with an adjustment plate for adjusting the direction.

[0011] Preferably, the tail fin consists of an upper V-shaped tail fin and a lower V-shaped tail fin, and the angle between the upper V-shaped tail fin and the lower V-shaped tail fin is 35°.

[0012] Furthermore, the adjustment mechanism includes a connecting mechanism with a reduced diameter, the tail fin is mounted on the connecting mechanism, and the connecting mechanism is reduced in diameter along a direction away from the first reinforcing ring.

[0013] Furthermore, the connecting mechanism includes a second reinforcing ring and a third reinforcing ring coaxially arranged with the first reinforcing ring. The third reinforcing ring is located on the side of the second reinforcing ring away from the first reinforcing ring. The inner diameters of the second and third reinforcing rings are reduced in the direction away from the first reinforcing ring. The second and third reinforcing rings are connected by a second connecting hose arranged around their axis. The mounting end of the tail fin is fixedly connected to the second and third reinforcing rings.

[0014] Furthermore, the tail fin includes a tail plate, the adjusting plate is rotatably disposed on the side of the tail plate away from the first reinforcing ring, the tail plate has a built-in rotating shaft arranged perpendicular to the axis of the connecting mechanism, the adjusting plate is mounted on the rotating shaft, and the tail plate also has a built-in micro motor for driving the rotating shaft.

[0015] Furthermore, the first reinforcing ring, the second reinforcing ring, and the third reinforcing ring are all made of hard metal, while the first connecting hose and the second connecting hose are made of ABS plastic.

[0016] This utility model has the following beneficial effects during use:

[0017] The first reinforcing ring is connected to the end of the refueling pipe. The tail fin on the adjustment mechanism is used to increase the stability of the refueling sleeve. When encountering interference such as the tail fin of the refueling aircraft or atmospheric turbulence, the adjustment plate can be moved to adjust the movement of the docking device in conjunction with the tail fin, providing a horizontal steering force for the docking device. Thus, even in the case of airflow interference, the overall stability of the docking device can be ensured, thereby reducing the swaying amplitude caused by airflow disturbance during refueling and reducing the docking difficulty during UAV refueling.

[0028] Please refer to Figures 1 to 3 As shown, an aerial refueling auxiliary docking device includes a first reinforcing ring 1 and an adjustment mechanism arranged coaxially. The first reinforcing ring 1 and the adjustment mechanism are connected by a first connecting hose 2 arranged around its axis.

[0029] The outer wall of the adjustment mechanism is provided with a tail wing 3, and the end of the tail wing 3 facing away from the first reinforcing ring 1 is provided with an adjustment plate 4 for adjusting the direction.

[0030] In this way, the first reinforcing ring 1 is connected to the end of the refueling pipe, and the tail fin 3 constructed on the adjustment mechanism is used to increase the stability of the refueling sleeve. When encountering interference such as the tail fin of the refueling aircraft and atmospheric turbulence, the adjustment plate 4 can be moved to adjust the movement of the docking device in conjunction with the tail fin 3, providing a horizontal steering force for the docking device. Thus, even in the state of airflow interference, the overall stability of the docking device can be ensured, thereby reducing the swing amplitude caused by airflow disturbance during refueling and reducing the docking difficulty during the UAV refueling process.

[0031] Furthermore, in order to ensure that the entire docking device moves stably under the adjustment of the tail fin 3 after the tail fin 3 is installed, the tail fin 3 is composed of an upper V-shaped tail fin 5 and a lower V-shaped tail fin 6, with the angle between the upper V-shaped tail fin 5 and the lower V-shaped tail fin 6 being 35°.

[0032] Furthermore, the adjustment mechanism includes a reduced-diameter connecting mechanism, on which the tail wing 3 is mounted, and the connecting mechanism is reduced-diameter along a direction away from the first reinforcing ring 1.

[0033] Furthermore, the connecting mechanism includes a second reinforcing ring 7 and a third reinforcing ring 8 coaxially arranged with the first reinforcing ring 1. The third reinforcing ring 8 is located on the side of the second reinforcing ring 7 away from the first reinforcing ring 1. The inner diameters of the second reinforcing ring 7 and the third reinforcing ring 8 are reduced along the direction away from the first reinforcing ring 1. The second reinforcing ring 7 and the third reinforcing ring 8 are connected by a second connecting hose 9 arranged around their axis. The mounting end of the tail fin 3 is fixedly connected to the second reinforcing ring 7 and the third reinforcing ring 8.

[0034] In this way, by using the second reinforcing ring 7 and the third reinforcing ring 8, not only can the first connecting hose 2 be prevented from getting tangled, but also the connecting mechanism can be made to form a hollow structure under the action of the second connecting hose 9. This ensures the stability of the entire docking device under the influence of airflow and its resistance to airflow influence while ensuring a low overall weight.

[0035] Furthermore, the tail fin 3 includes a tail plate 10, an adjusting plate 4 is rotatably disposed on the side of the tail plate 10 away from the first reinforcing ring 1, the tail plate 10 has a built-in rotating shaft arranged perpendicular to the axis of the connecting mechanism, the adjusting plate 4 is mounted on the rotating shaft, and the tail plate 10 also has a built-in micro motor for driving the rotating shaft.

[0036] In this way, the direction of movement of the entire docking device can be adjusted according to the airflow by using the rotation of the adjusting plate 4 around the rotating shaft.

[0037] Furthermore, the first reinforcing ring 1, the second reinforcing ring 7, and the third reinforcing ring 8 are all hard metal rings, while the first connecting hose 2 and the second connecting hose 9 are made of ABS plastic.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
