Description

Technical Field

[0001] The invention belongs to the technical field of aircraft aerial refueling, and in particular relates to a rotary wing ring-type aerial refueling active stabilization cone sleeve. Background Art

[0002] The application of aerial refueling technology has increased the range of aircraft, increased efficiency and other capabilities, and made it possible to complete tasks that were previously impossible. In addition, aerial refueling technology has overturned the traditional concept of human beings about the types of missions performed by aircraft. For the current hose-type aerial refueling method, due to the influence of atmospheric turbulence and the head wave generated by the front of the receiving aircraft, coupled with the flexibility of the refueling hose, the spatial position of the refueling drogue relative to the refueling aircraft cannot be fixed, and there is a swaying phenomenon within a certain range.

[0003] There are two disadvantages of the current soft aerial refueling method:

[0004] First, the drogue has a swaying phenomenon, which increases the difficulty of high-precision aerial refueling docking, resulting in a longer refueling docking time;

[0005] Second, when the receiving aircraft approaches the refueling drogue, its front head wave may induce the refueling drogue to oscillate, leading to related refueling accidents.

[0006] At present, the active stabilization control of the drogue mainly focuses on the wing-rudder stabilization control method, that is, by adding operating control surfaces to the drogue, the drogue swing amplitude is controlled based on the direct force control method. However, the problems of this type of solution are: the stabilization control surfaces are directly connected to the driving servo, the structural strength is poor, and it is easy to collide with the tanker hatch during the release and recovery process of the drogue, causing damage, and also brings certain safety risks. Summary of the invention

[0007] In order to solve the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a rotary wing ring type aerial refueling active stabilization drogue, so as to realize the control of the attitude and position of the drogue by controlling the front and rear rotary wing rings to rotate to different positions to generate aerodynamic force, thereby suppressing the swing and "head wave" phenomenon of the hose drogue system during the aerial refueling docking process, improving the efficiency, accuracy and safety of the drogue docking, and reducing the occurrence of accidents.

[0008] The technical solution adopted by the present invention is:

[0009] A spinning wing ring type aerial refueling active stabilization cone sleeve comprises an inner cone ring, on which at least two spinning wing rings are rotatably connected, and on which a flight control system, a positioning system, and a radio high-speed data transmission system are respectively installed, and on which a plurality of servo motors are installed, and between which the output ends of the servo motors and the spinning wing rings are connected drive components; the positioning system and the radio high-speed data transmission system are both electrically connected to the flight control system, and the flight control system is electrically connected to the servo motor.

[0010] The ground station sends a command through the radio high-speed data transmission system to unlock the flight control system (start working). During the aerial refueling process, the drogue is disturbed and swings disorderly. The flight control system obtains the spatial position and flight speed of the drogue through the positioning system, calculates according to the relevant data, and sends an angle command to the servo motor. The servo motor adjusts the position of the rotor ring through the drive assembly. The rotors between different rotor rings are in different positions, so that the rotor rings generate corresponding aerodynamic forces, thereby controlling the attitude of the drogue and achieving stabilization of the hose-type aerial refueling drogue. When releasing and recovering the drogue, the tanker generates different aerodynamic forces by autonomously rotating each rotor ring, thereby controlling the attitude of the drogue.

[0011] Compared with traditional aerial refueling technology, the rotating wing ring aerial refueling active stabilization cone of the present invention suppresses the flutter caused by atmospheric turbulence, wake, wingtip vortex, etc. during the release and recovery process of the drogue sleeve, so that the drogue sleeve is in a stable state during the release and recovery process, and the release and recovery of the drogue sleeve can be achieved quickly, safely and stably; during the docking process of the drogue sleeve and the refueling pipe, the "head wave" phenomenon caused by the approach of the receiving aircraft to the front of the refueling drogue sleeve is suppressed, thereby improving the efficiency of the drogue sleeve docking and reducing the occurrence of accidents.

[0012] As a preferred solution of the present invention, the inner ring of the cone is also equipped with a battery and a power module, the battery and the power module are electrically connected, and the flight control system, the positioning system, the radio high-speed data transmission system and the servo motor are electrically connected to the power module. The battery supplies power to the flight control system, the positioning system, the radio high-speed data transmission system and the servo motor through the power module. The power module can maintain a constant voltage.

[0013] As a preferred solution of the present invention, the driving assembly includes a driving gear and an internal gear that mesh with each other, the driving gear is connected to the output end of the servo motor, and the internal gear is fixed to the inner wall of the spinning wing ring. The servo motor drives the driving gear to rotate, and the driving gear drives the internal gear to rotate, so that the spinning wing ring rotates accordingly.

[0014] As a preferred embodiment of the present invention, the self-rotating wing ring includes a wing ring body, which is rotatably connected to the inner ring of the cone, and a plurality of rotors are fixed on the wing ring body.

[0015] As a preferred embodiment of the present invention, the number of the rotating wing rings rotatably connected to the cone inner ring is two, and the rotors on the two rotating wing rings are tilted in opposite directions relative to the cone inner ring. The rotors on the two rotating wing rings are tilted in opposite directions relative to the cone inner ring, ensuring that the aerodynamic force is zero in the initial state. The front rotating wing ring rotates counterclockwise, and the rear rotating wing ring rotates clockwise, with the same rotation angle, so that the two rotating wing rings generate aerodynamic forces in the same direction to control the movement of the cone sleeve.

[0016] As a preferred solution of the present invention, the number of rotors on the wing ring body is two, and the two rotors are symmetrically arranged on the wing ring body. The rotation of the wing ring body changes the position of the rotors on it, and the rotors of different self-rotating wing rings are in different positions, thereby generating corresponding aerodynamic forces, controlling the attitude of the drogue, and making the drogue stable throughout the release and recovery process. Compared with the current tanker, which has swaying during the release and recovery of the drogue, the stability and safety of the drogue release and recovery process are improved.

[0017] As a preferred solution of the present invention, both sides of the spinning wing ring are rotatably connected to the inner ring of the cone through bearings.

[0018] As a preferred solution of the present invention, one side of the inner ring of the cone is connected to a cone cup.

[0019] As a preferred embodiment of the present invention, one end of the inner ring of the cone away from the cone cup is connected to an umbrella rib, and the other end of the umbrella rib is connected to an umbrella canopy.

[0020] As a preferred solution of the present invention, the positioning system is a Beidou satellite navigation system or a global positioning system.

[0021] The beneficial effects of the present invention are:

[0022] The rotating wing ring-type aerial refueling active stabilization cone of the present invention suppresses the flutter caused by atmospheric turbulence, wake flow, wingtip vortex, etc. during the release and recovery process of the drogue sleeve, so that the drogue sleeve is in a stable state during the release and recovery process, and the release and recovery of the drogue sleeve can be achieved quickly, safely and stably; during the docking process of the drogue sleeve and the refueling pipe, the "head wave" phenomenon caused by the approach of the receiving aircraft to the front of the refueling drogue sleeve is suppressed, thereby improving the efficiency of the drogue sleeve docking and reducing the occurrence of accidents.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0034] like Figure 1 to Figure 6 As shown, the rotary wing ring-type aerial refueling active stabilization cone sleeve of this embodiment includes a cone inner ring 1, one side of the cone inner ring 1 is connected to a cone cup 5, the end of the cone inner ring 1 away from the cone cup 5 is connected to an umbrella rib 6, and the other end of the umbrella rib 6 is connected to a canopy 7.

[0035] The inner ring 1 of the cone is connected to two spinning wing rings 2 through a bearing 16. A flight control system 11, a global positioning system 12 (GPS), and a radio high-speed data transmission system 13 are also installed on the inner ring 1 of the cone. Several servo motors 3 are installed on the inner ring 1 of the cone. A driving component 4 is connected between the output end of the servo motor 3 and the spinning wing ring 2; the global positioning system 12 and the radio high-speed data transmission system 13 are both electrically connected to the flight control system 11, and the flight control system 11 is electrically connected to the servo motor 3.

[0036] The driving assembly 4 includes a driving gear 41 and an internal gear 42 meshing with each other. The driving gear 41 is connected to the output end of the servo motor 3 , and the internal gear 42 is fixed to the inner wall of the spinning wing ring 2 .

[0037] The ground station sends a command through the radio high-speed data transmission system 13 to unlock the flight control system 11 (start working). During the aerial refueling process, the cone sleeve is disturbed and swings disorderly. The flight control system 11 obtains the spatial position and flight speed of the cone sleeve through the global positioning system 12, and sends an angle command to the servo motor 3 based on the relevant data calculation. The servo motor 3 drives the active gear 41 to rotate, and the active gear 41 drives the internal gear 42 to rotate, so that the rotor ring 2 rotates accordingly. The rotors 22 on different rotor rings 2 are in different positions, so that the rotor rings 2 generate corresponding aerodynamic forces, thereby controlling the posture of the cone sleeve and achieving stabilization of the hose-type aerial refueling cone sleeve. When releasing and recovering the cone sleeve, the tanker generates different aerodynamic forces by autonomously rotating each rotor ring 2, thereby controlling the posture of the cone sleeve.

[0038] Compared with traditional aerial refueling technology, the rotating wing ring 2 type aerial refueling active stabilization cone of the present invention suppresses the flutter caused by atmospheric turbulence, wake, wingtip vortex, etc. during the release and recovery process of the drogue, so that the drogue is in a stable state during the release and recovery process, and the release and recovery of the drogue can be achieved quickly, safely and stably; during the docking process of the drogue and the refueling pipe, the "head wave" phenomenon caused by the approach of the receiving aircraft to the front of the refueling drogue is suppressed, thereby improving the efficiency of the drogue docking and reducing the occurrence of accidents. Figure 7 The Y-direction motion curve of the drogue sleeve of the rotary wing ring 2 type aerial refueling active stabilization of the present invention in the uncontrolled / stabilized state; Figure 8 This is the Z-direction motion curve of the cone sleeve of the spinning wing ring 2 type aerial refueling active stabilization in the uncontrolled / stabilized state of the present invention.

[0039] Furthermore, the cone inner ring 1 is also equipped with a battery 14 and a power module 15, which are electrically connected to each other, and the flight control system 11, the global positioning system 12, the radio high-speed data transmission system 13 and the servo motor 3 are electrically connected to the power module 15. The battery 14 supplies power to the flight control system 11, the global positioning system 12, the radio high-speed data transmission system 13 and the servo motor 3 through the power module 15. The power module 15 can maintain a constant voltage.

[0040] Specifically, the autogyro wing ring 2 includes a wing ring body 21, which is rotatably connected to the cone inner ring 1, and a plurality of rotors 22 are fixed on the wing ring body 21. There are two rotors 22 on the wing ring body 21, and the two rotors 22 are symmetrically arranged on the wing ring body 21. The rotation of the wing ring body 21 changes the position of the rotors 22 thereon, and the rotors 22 of different autogyro wing rings 2 are in different positions, thereby generating corresponding aerodynamic forces, controlling the attitude of the drogue, and making the drogue stable throughout the entire release and recovery process. Compared with the current tanker, which has the problem of swaying during the release and recovery of the drogue, the stability and safety of the drogue release and recovery process are improved.

[0041] There are two rotor rings 2 rotatably connected to the cone inner ring 1, and the rotors 22 on the two rotor rings 2 are tilted in opposite directions relative to the cone inner ring 1. The rotors 22 on the two rotor rings 2 are tilted in opposite directions relative to the cone inner ring 1, ensuring that the aerodynamic force is zero in the initial state. The front rotor ring 2 rotates counterclockwise, and the rear rotor ring 2 rotates clockwise, with the same rotation angle, so that the two rotor rings 2 generate aerodynamic forces in the same direction to control the movement of the cone sleeve.

[0042] Working process:

[0043] During the release process of the drogue, the drogue is disturbed and sways disorderly. The flight control system 11 processes the position and speed signals of the drogue measured by the sensor, solves and transmits the command signal to control the rotation of the servo motor 3. The servo motor 3 drives the rotary wing ring 2 to rotate through the drive assembly 4. The rotors 22 between different rotary wing rings 2 are in different positions, generating corresponding aerodynamic forces, thereby controlling the attitude of the drogue, so that the drogue is stable throughout the release process. During this process, the receiving aircraft follows behind. When the drogue is released to the predetermined position, the receiving aircraft accelerates to approach, and slowly approaches when reaching the area, while extending the receiving pipe to start docking with the drogue. During the docking process between the receiving pipe and the drogue, the flight control system 11 controls the servo motor 3 to rotate, controls the rotors 22 on the two rotary wing rings 2 to be in the corresponding positions, generates the required aerodynamic force to suppress the head wave phenomenon caused by the receiving aircraft approaching the front of the refueling drogue, and completes the docking to start aerial refueling. After completing the aerial refueling, the receiving aircraft flies away and the tanker begins to recover the drogue. In this process, the drag surface is also controlled to generate differential force, the attitude of the drogue is controlled to suppress its swing, and the drogue is recovered into the tanker, completing the entire aerial refueling process.

[0044] The present invention is applicable to aerial refueling of both manned aircraft and unmanned aircraft.

[0045] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
