Description

Technical Field

[0001] The utility model belongs to the technical field of in-air refueling, and particularly relates to an in-air refueling stability-enhancing conical sleeve based on active jet control. Background Art

[0002] The application of in-air refueling technology has increased the flight range of aircraft, significantly improved the survivability of fighter jets, and significantly enhanced capabilities such as efficiency, making tasks that were previously impossible possible. In addition, in-air refueling technology has subverted the traditional concept of the types of tasks that fighter jets can perform in the past, giving people a new understanding of the combat capabilities of in-air refueling tankers supporting fighter jets. For the current hose-type in-air refueling method, due to the influence of atmospheric turbulence and the head wave generated by the forebody of the receiving aircraft, combined with the flexibility of the refueling hose, the spatial position of the refueling conical sleeve relative to the tanker cannot be fixed, and there is a fluttering phenomenon within a certain range. It can be seen that currently, the soft-type in-air refueling method has two disadvantages: one is that due to the fluttering of the conical sleeve, the time for the refueling docking process is relatively long; the other is that when the receiving aircraft approaches the refueling conical sleeve, the head wave of its forebody may induce the oscillation of the refueling conical sleeve, resulting in related refueling accidents. Content of the Utility Model

[0003] In order to solve the above problems existing in the prior art, the purpose of the utility model is to provide an in-air refueling stability-enhancing conical sleeve based on active jet control, so as to realize the active control of the attitude of the conical sleeve through jet flow, thereby suppressing the disordered fluttering and "head wave" phenomena that occur in the hose conical sleeve system during the in-air refueling docking process, improving the efficiency and accuracy of conical sleeve docking, and reducing the occurrence of accidents.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An in-air refueling stability-enhancing conical sleeve based on active jet control includes an oil delivery pipeline, one end of the oil delivery pipeline is connected with a conical cup, a plurality of air delivery pipelines are arranged on the oil delivery pipeline, a plurality of jet ports are arranged on the outer wall of the conical cup, the air delivery pipelines are in one-to-one correspondence and communication with the jet ports, and a flight control system, a positioning system and a radio high-speed data transmission system are installed in the conical cup; it also includes a jet system and a gas supply device arranged in the tanker, the jet system is electrically connected with the gas supply device, the positioning system and the radio high-speed data transmission system are both electrically connected with the flight control system, and the flight control system is electrically connected with the jet system.

[0006] The ground station sends commands through a radio high-speed data transmission system to unlock (start working) the flight control system. During the release and recovery of the drogue, the flight control system receives data such as the spatial position and attitude transmitted in real time by the positioning system on the drogue, controls the action of the gas supply device through the jet system, and controls the drogue attitude by generating corresponding forces through controlling the speed and size of the jet, so as to control the relative fixation of the drogue spatial position. Thereby suppressing problems such as the head wave phenomenon generated by the forebody of the receiver approaching the refueling drogue and the disorderly fluttering of the drogue caused by atmospheric turbulence. Compared with the current situation where the refueling hose and the drogue may induce the oscillation of the refueling drogue during the docking process, resulting in related refueling accidents, the safety of the in-air refueling docking process is improved, while the efficiency of the docking process is reduced.

[0007] For traditional in-air refueling technology, the jet active control of the present invention can suppress the fluttering caused by atmospheric turbulence during the release of the drogue; during the docking process with the refueling hose, it can suppress problems such as the "head wave" phenomenon generated by the forebody of the receiver approaching the refueling drogue and the disorderly fluttering of the drogue caused by atmospheric turbulence, thereby improving the efficiency of drogue docking and reducing the occurrence of accidents.

[0008] As a preferred solution of the present invention, the gas transmission pipeline is arranged on the inner wall of the oil transmission pipeline. The gas transmission pipeline is hidden in the inner wall of the oil transmission pipeline.

[0009] As a preferred solution of the present invention, an inclined channel is arranged between the oil transmission pipeline and the jet orifice. The inclined channel is arranged on the conical cup. The inclined channel connects the gas transmission pipeline and the jet orifice to ensure the stable transmission of gas to the jet orifice.

[0010] As a preferred solution of the present invention, the number of the jet orifices and the gas transmission pipelines is four each.

[0011] As a preferred solution of the present invention, the four jet orifices are circumferentially evenly distributed on the outer wall of the conical cup. The four jet orifices are evenly distributed on the conical cup, which is convenient for controlling the drogue attitude by controlling the gas speed and flow rate of the jet orifices at different positions.

[0012] As a preferred solution of the present invention, the jet orifice is perpendicular to the axis of the conical cup.

[0013] As a preferred solution of the present invention, the positioning system is a Beidou satellite navigation system or a global positioning system.

[0014] As a preferred solution of the present invention, a rib is connected to one end of the conical cup away from the oil transmission pipeline.

[0015] As a preferred solution of the present invention, a parachute canopy is connected to the other end of the rib away from the conical cup.

[0016] As a preferred solution of the present invention, the gas supply device is an air pump.

[0017] The beneficial effects of the present utility model are as follows:

[0018] The jet active control of the present utility model can suppress the flutter caused by atmospheric turbulence during the cone sleeve release process; during the docking process with the receiving oil pipe, it can suppress problems such as the "head wave" phenomenon generated by the forebody of the receiving aircraft approaching the refueling cone sleeve and the disordered flutter of the cone sleeve caused by atmospheric turbulence, thereby improving the efficiency of the cone sleeve docking and reducing the occurrence of accidents.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model that is required to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0025] As Figures 1 to 3 shown, the in-flight refueling stability-enhancing cone sleeve based on active jet control in this embodiment includes an oil pipeline 1, one end of the oil pipeline 1 is connected to a cone cup 2, the end of the cone cup 2 far from the oil pipeline 1 is connected to an umbrella rib 7, and the end of the umbrella rib 7 far from the cone cup 2 is connected to an umbrella canopy 8.

[0026] A number of gas pipelines 3 are provided on the oil pipeline 1. A number of jet orifices 21 are provided on the outer wall of the conical cup 2. The gas pipelines 3 are in one-to-one correspondence and communication with the jet orifices 21. A flight control system, a positioning system 4 and a radio high-speed data transmission system 5 are installed inside the conical cup 2; It also includes a jet system 6 and a gas supply device arranged in the fuel dispenser. The gas supply device is an air pump. The jet system 6 is electrically connected to the gas supply device. The positioning system 4 and the radio high-speed data transmission system 5 are both electrically connected to the flight control system. The flight control system is electrically connected to the jet system 6.

[0027] The ground station sends an instruction through the radio high-speed data transmission system 5 to unlock (start working) the flight control system. During the process of releasing and recovering the conical sleeve, the flight control system receives data such as the spatial position and attitude transmitted in real time by the positioning system 4 on the conical sleeve, controls the action of the gas supply device through the jet system 6, and controls the attitude of the conical sleeve by generating corresponding forces by controlling the speed and size of the jet, so as to control the relative fixation of the spatial position of the conical sleeve. Thereby suppressing problems such as the head wave phenomenon generated by the forebody of the receiver approaching the refueling conical sleeve and the disorderly swaying of the conical sleeve caused by atmospheric turbulence. Compared with the current refueling process in which the refueling pipe and the conical sleeve may induce the oscillation of the refueling conical sleeve, resulting in related refueling accidents, the safety of the in-air refueling docking process is improved, and at the same time the efficiency of the docking process is reduced.

[0028] For traditional in-air refueling technology, the jet active control of the present invention can suppress the sway caused by atmospheric turbulence during the release process of the conical sleeve; during the docking process with the refueling pipe, it can suppress problems such as the "head wave" phenomenon generated by the forebody of the receiver approaching the refueling conical sleeve and the disorderly swaying of the conical sleeve caused by atmospheric turbulence, thereby improving the docking efficiency of the conical sleeve and reducing the occurrence of accidents.

[0029] In this embodiment, the gas pipelines 3 are arranged on the inner wall of the oil pipeline 1. The gas pipelines 3 are hidden inside the inner wall of the oil pipeline 1.

[0030] Furthermore, an inclined channel 22 is provided between the oil pipeline 1 and the jet orifice 21. The inclined channel 22 is arranged on the conical cup 2. The inclined channel 22 connects the gas pipeline 3 and the jet orifice 21 to ensure the smooth delivery of gas to the jet orifice 21.

[0031] In this embodiment, the number of the jet orifices 21 and the gas pipelines 3 is four each. The four jet orifices 21 are evenly distributed circumferentially on the outer wall of the conical cup 2. The four jet orifices 21 are evenly distributed on the conical cup 2, which is convenient for controlling the attitude of the conical sleeve by controlling the gas speed and flow rate of the jet orifices 21 at different positions.

[0032] The jet orifice 21 is perpendicular to the axis of the conical cup 2.

[0033] The positioning system 4 is a Beidou satellite navigation system or a global positioning system 4. In this embodiment, the positioning system 4 is a global positioning system 4 (GPS).

[0034] Working process:

[0035] During the in-air refueling process, when the tanker reaches the predetermined flight path, it releases the drogue. Under the action of resistance, the parachute canopy 8 unfolds and at the same time the parachute ribs 7 open. The flight control system controls the jet system 6 by receiving the data such as the spatial position and attitude transmitted in real time by the global positioning system 4 on the drogue. The jet system 6 controls the action of the gas supply device, thereby controlling the magnitude of the force generated by the jet velocity to control the attitude of the drogue and suppress the sway caused by atmospheric turbulence. During this process, the receiver aircraft follows behind. When the drogue is released to the predetermined position, the receiver aircraft accelerates and approaches. When it reaches the area, it approaches slowly. At the same time, it extends the refueling pipe and starts to dock with the drogue to start in-air refueling. After the in-air refueling is completed, the tanker flies away and starts to recover the drogue. During this process, the force generated by the velocity of the jet gas is also controlled to control the attitude of the drogue and suppress its sway, and the drogue is recovered into the fuel supply aircraft to complete the entire in-air refueling process.

[0036] The utility model is applicable to in-air refueling of both manned aircraft and unmanned aircraft.

[0037] The utility model is not limited to the above optional embodiments. Any person can obtain other various forms of products under the inspiration of the utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the utility model, they are all within the protection scope of the utility model.
