[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) countermeasures, and in particular to an unmanned aerial vehicle (UAV) combat system and a combat method. Background Art

[0002] The UAV strike device is an important part of UAV technology. It combines the dual capabilities of reconnaissance and strike, greatly improving combat efficiency and accuracy. The following is a detailed introduction to the UAV strike device:

[0003] 1. System composition

[0004] UAV strike devices are usually integrated into UAV platforms, including reconnaissance systems, strike systems, and data transmission systems. The reconnaissance system is responsible for collecting target information in real time, the strike system carries out precise strikes on targets based on the reconnaissance results, and the data transmission system is responsible for transmitting reconnaissance data and strike commands between the UAV and the ground command system.

[0005] 2. Reconnaissance System

[0006] The reconnaissance system is mainly composed of an optoelectronic gimbal, a multi-band optoelectronic camera, a high-sensitivity thermal imager, and a laser rangefinder. The optoelectronic gimbal is responsible for autonomously identifying and searching for targets, and locking and tracking them. The multi-band optoelectronic camera and the high-sensitivity thermal imager provide images and video information in different bands to provide a more comprehensive understanding of the target. The laser rangefinder is used to accurately measure the distance between the target and the drone, providing accurate target location information for the strike system.

[0007] 3. Strike System

[0008] The strike system may include different types of strike payloads depending on the type of drone and mission requirements. For example, some drones may be equipped with automatic rifle devices, launchers (capable of firing smoke bombs, tear gas, etc.) or mortar shell throwers. These strike payloads enable drones to perform high-altitude strike missions and achieve precise strikes and suppression of ground targets.

[0009] Problems with existing technologies:

[0010] The existing strike systems all use drones as carrier platforms. When the strike system is shooting, the recoil will cause the drone to shake significantly, thereby affecting the strike accuracy and may even cause the drone to lose control. Summary of the invention

[0011] In view of this, the present invention provides a UAV combat system and a combat method, so as to achieve the purpose of not causing the UAV to shake significantly when the strike system is shooting.

[0013] The present invention also provides a UAV combat method, which is performed using the UAV combat system.

[0014] Compared with the prior art, the beneficial effects that can be achieved by at least one of the above-mentioned technical solutions adopted by the present invention include at least: by setting a slide rail and a slider structure, the airborne combat device can slide flexibly, and combined with the precise reverse thrust of the reverse thrust device, the recoil force generated when the weapon is fired can be effectively offset, which significantly improves the flight stability and shooting accuracy of the UAV during the shooting process, enhances the combat effectiveness and mission adaptability of the UAV, and at the same time reduces the impact and vibration on the UAV body structure, thereby extending the service life of the UAV.

[0018] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0019] The following describes the implementation methods of the present application through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0020] like Figure 1 As shown, an embodiment of the present invention provides a UAV combat system, including a UAV body 10, a slide rail 20, a slider 30, an airborne combat device 40 and a reverse thrust device 50. The slide rail 20 is arranged at the bottom of the UAV body 10; the slider 30 is connected with the slide rail 20 and can slide relative to the UAV body 10 along the extension direction of the slide rail 20; the airborne combat device 40 is connected with the slider 30, and the airborne combat device 40 can slide with the slider 30; the reverse thrust device 50 is connected with the slider 30, and the reverse thrust device 50 and the airborne combat device 40 are respectively arranged on two opposite side walls of the slider 30.

[0021] An unmanned aerial vehicle combat system provided by an embodiment of the present invention enables an airborne combat device 40 to slide flexibly by setting a slide rail 20 and a slider 30 structure. Combined with the precise reverse thrust of the reverse thrust device 50, the recoil force generated when the weapon is fired is effectively offset, thereby significantly improving the flight stability and shooting accuracy of the unmanned aerial vehicle during the shooting process, enhancing the combat effectiveness and mission adaptability of the unmanned aerial vehicle, and at the same time reducing the impact and vibration on the structure of the unmanned aerial vehicle body 10, thereby extending the service life of the unmanned aerial vehicle.

[0022] It should be noted that the airborne combat device 40 and the reverse thrust device 50 only need to be in the same straight line, and the installation position of the slider 30 is not limited and can be adjusted and selected according to different needs.

[0023] The reverse thrust device 50 includes a control system and a reverse thrust fan. The control system is arranged in the accommodation space inside the slider 30, and the reverse thrust fan is fixedly arranged on the outer side wall of the slider 30. The control system is electrically connected to the reverse thrust fan.

[0024] The thrust reverser 50 achieves precise control of the thrust reverser by integrating the control system into the slider 30 and fixing the thrust reverser fan on the outer wall of the slider 30. This design not only improves the integration and reliability of the system, but also enables the thrust reverser 50 to respond quickly and adjust the thrust reverser according to the real-time monitoring data, effectively offsetting the recoil of the weapon when firing, and maintaining the flight stability and attitude control of the UAV.

[0025] In addition, the precise control of the thrust reverser 50 reduces the impact and vibration on the structure of the drone body 10 during shooting, reduces the structural stress, and prolongs the service life of the drone. At the same time, it also improves the shooting accuracy of the airborne combat device 40, enhances the flexibility and adaptability of the drone in different combat missions, and enables it to better cope with diverse combat needs.

[0026] The control system includes a displacement sensor for detecting the displacement of the slider 30, an inductive sensor for detecting the relative position of the slider 30 and the slide rail 20, and a control unit. The control unit can receive electrical signals from the displacement sensor and the inductive sensor and control the rotation speed of the reverse thrust fan.

[0027] The control system can monitor the displacement of the slider 30 and its relative position to the slide rail 20 in real time through the displacement sensor and the induction sensor, and transmit these electrical signals to the control unit. The control unit accurately controls the speed of the reverse thrust fan according to these signals, thereby realizing precise adjustment of the reverse thrust. This design significantly improves the flight stability and attitude control ability of the drone during shooting, effectively reduces the impact and vibration of the recoil on the structure of the drone body 10, reduces structural stress, and extends the service life of the drone. At the same time, precise reverse thrust control also improves the shooting accuracy of the airborne combat device 40, enhances the flexibility and adaptability of the drone in different combat missions, and enables it to better cope with diverse combat needs.

[0028] The UAV combat system also includes an energy recovery device, which is arranged in the slider 30 and connected to the reverse thrust fan.

[0029] Specifically, the energy recovery device includes a micro generator and an energy storage unit. The micro generator is connected to the rotating shaft of the reverse thrust fan to generate electricity, and the energy storage unit is connected to the micro generator.

[0030] The energy recovery device converts the mechanical energy of the reverse thrust fan into electrical energy and stores it through a micro generator and energy storage unit, significantly improving the energy efficiency of the drone and reducing energy waste. In an emergency, the energy storage unit serves as a backup power source to ensure that the key systems of the drone (such as the control system, communication system, etc.) can continue to operate, enhancing the survivability and system reliability of the drone in complex environments.

[0031] The integration of the energy recovery device and the control system realizes the automatic management and distribution of energy. The control system automatically adjusts the power generation of the micro-generator and the charging and discharging status of the energy storage unit according to the flight status and energy demand of the drone, improving the automation and operation efficiency of the system. By effectively utilizing the recovered energy, the flight time and range of the drone are extended, enhancing its flight performance and enabling it to better perform long-term missions.

[0032] The energy recovery device provides additional energy support for the UAV's onboard combat device and reverse thrust device, ensuring stable performance in high-energy consumption tasks. The energy storage unit can provide instant energy for the reverse thrust device, enhance the reverse thrust effect, and further improve the stability and shooting accuracy of the UAV during shooting, thereby enhancing its combat effectiveness and enabling it to better respond to diverse combat needs.

[0033] The reverse thrust device 50 also includes a propeller pitch adjustment device, which is arranged in the reverse thrust fan and is used to adjust the blade angle of the reverse thrust fan. The propeller pitch adjustment device can automatically adjust the blade angle of the reverse thrust fan according to the flight state and the requirements of the shooting mission to optimize the reverse flow of the airflow and further reduce the impact of the recoil on the drone. The adjustment of the blade angle is automatically controlled by the control system according to the signals of the displacement sensor and the induction sensor.

[0034] Through the propeller pitch adjustment device, the blade angle of the reverse thrust fan can be automatically adjusted according to the flight status and shooting mission requirements, optimizing the reverse flow of the airflow, further reducing the impact of recoil on the UAV, and improving flight stability and shooting accuracy.

[0035] The addition of the propeller pitch adjustment device enables the reverse thrust device to better adapt to different flight conditions and shooting missions, enhancing the combat flexibility and adaptability of the UAV.

[0036] In an embodiment not shown in the figure, the reverse thrust device 50 is a hydraulic buffer; when the onboard weapon is fired, the recoil acts on the hydraulic buffer, and the piston rod of the hydraulic buffer is subjected to pressure, driving the piston to squeeze the hydraulic oil in the inner tube. After the hydraulic oil is pressurized, it is discharged from the oil discharge hole of the inner tube, part of it flows back to the inner tube through the oil return hole, and the other part enters the pressure storage sponge. After the external force disappears, the spring quickly pushes the piston rod to reset, negative pressure is formed in the inner tube, the check valve automatically opens, and the hydraulic oil quickly returns to the inner tube through the opened check valve, and the hydraulic buffer returns to its initial state.

[0037] This embodiment absorbs and buffers the recoil force through the hydraulic buffer, which greatly reduces the recoil force and its impact on the UAV, and is beneficial to improving the flight stability of the UAV and protecting the internal components.

[0038] Furthermore, a spring buffer is added on the basis of the hydraulic buffer. The spring buffer is compressed under the action of recoil, absorbing part of the energy, further reducing the impact of recoil on the drone. When the recoil disappears, the spring quickly returns to its original state, pushing the relevant components to reset.

[0039] The spring buffer can provide additional cushioning effect, enhance the shock absorption capacity of the entire system, and ensure the rapid stabilization of the drone after shooting.

[0040] In an embodiment not shown in the figure, the present invention further includes an adaptive damper: arranged between the slider 30 and the reverse thrust fan, for further absorbing and dispersing the recoil. The adaptive damper can automatically adjust the damping coefficient according to the magnitude of the recoil, ensuring that the impact of the recoil on the drone can be effectively reduced under different shooting conditions. The damping coefficient adjustment of the adaptive damper is automatically controlled by the control system according to the signals of the displacement sensor and the induction sensor.

[0041] The adaptive dampers consist of the following main components:

[0042] Sliding disc: connected to the slider and able to slide on the arc guide rail.

[0043] Arc guide rail: fixed on the slider, on which the sliding disc slides, generating a damping force corresponding to the recoil force.

[0044] Fixed disc: It is connected to the sliding disc through a disc connector without stiffness or damping. The fixed disc is made of iron.

[0045] Disc connector: used to connect the sliding disc and the fixed disc to ensure the relative movement between the two.

[0046] Eddy current damper: uses the eddy current principle to generate damping force, and adjusts the damping force by adjusting the current.

[0047] Sensor: including displacement sensor and speed sensor, used to monitor the displacement and speed of the slider in real time.

[0048] Control unit: According to the signal from the sensor, it automatically adjusts the current of the eddy current damper to adjust the damping force.

[0049] Working process:

[0050] Initial state: the slider is in the initial position, the sliding disc of the adaptive damper is in the middle position of the arc guide rail, and the eddy current damper is in standby state.

[0051] The moment of shooting: When the airborne combat device shoots, the recoil force acts on the slider, the slider slides backward along the slide rail, and the sliding disc slides on the arc guide rail.

[0052] Damping force adjustment: The displacement sensor and speed sensor detect the displacement and speed change of the slider and transmit the signal to the control unit. Based on these signals, the control unit automatically adjusts the current of the eddy current damper to increase the damping force to offset the recoil.

[0053] Recovery state: After shooting, the control unit gradually reduces the current of the eddy current damper, the slider returns to its initial position under the action of the spring or other reset mechanism, and the sliding disc also returns to the middle position of the arc guide rail.

[0054] This embodiment has the following beneficial effects:

[0055] Adaptive adjustment: It can automatically adjust the damping force according to the size of the recoil, ensuring that the impact of recoil on the drone can be effectively reduced under different shooting conditions.

[0056] High-precision control: Through precise control of sensors and control units, high-precision damping force adjustment is achieved to improve the flight stability and shooting accuracy of the UAV.

[0057] Simple structure: It adopts eddy current damper, which has simple structure, convenient maintenance and high reliability.

[0058] Energy recovery: Combined with the energy recovery module, part of the reverse thrust energy can be recovered and stored to improve the energy efficiency of the drone.

[0059] In an embodiment not shown in the figure, the thrust reverser has multiple modes and can be switched. The thrust reverser can switch different thrust reverser modes according to different shooting tasks and flight states, including standard thrust reverser mode, high-efficiency thrust reverser mode and low-noise thrust reverser mode. The switching of the multi-mode thrust reverser mode is automatically controlled by the control system according to the signals of the displacement sensor, the induction sensor and the environmental sensor.

[0060] This embodiment also includes a remote monitoring module: it can transmit the operating status and fault diagnosis information of the thrust reverser to the ground control station in real time, and the operator can remotely monitor and control the operation of the thrust reverser through the ground control station. The remote monitoring module includes a wireless communication module and a data processing unit. The data processing unit processes the sensor data and fault diagnosis information and transmits them to the ground control station through the wireless communication module.

[0061] The present invention also provides a UAV combat method, which is performed using a UAV combat system. The UAV combat method includes:

[0062] The airborne combat device 40 performs shooting, pushing the slide block 30 to slide along the slide rail 20;

[0063] The control system detects the movement of the slider 30 and controls the reverse thrust fan to rotate, thereby offsetting the recoil force generated when the airborne combat device 40 shoots.

[0064] Furthermore, at least three detection points are provided on the slide rail 20, and the UAV combat method includes:

[0065] When the slider 30 moves to the first detection point, the reverse thrust fan increases to the first speed;

[0066] When the slider 30 moves to the second detection point, the reverse thrust fan increases from the first speed to the second speed;

[0067] When the slider 30 moves to the third detection point, the reverse thrust fan increases from the second speed to the third speed.

[0068] The detection points of the embodiment of the present invention can be adjusted according to different needs, and the corresponding rotation speed of the reverse thrust fan can be adjusted according to the above working conditions.

[0069] It should be noted that the first rotational speed is smaller than the second rotational speed and smaller than the third rotational speed.

[0070] Drone combat methods include:

[0071] When the slider 30 is at the initial position, the blades of the reverse thrust fan are perpendicular to the rotation plane, and the reverse thrust fan starts to rotate but does not provide any reverse thrust;

[0072] When the airborne combat device 40 shoots, the slider 30 moves backwards, and when the slider 30 moves to the first detection point, the propeller pitch adjustment device adjusts the blades of the reverse thrust fan to a position having a first angle with the rotation plane;

[0073] When the slider 30 moves to the second detection point, the propeller pitch adjustment device adjusts the blades of the reverse thrust fan to a position having a second angle with the rotation plane;

[0074] When the slider 30 moves to the third detection point, the propeller pitch adjustment device adjusts the blades of the reverse thrust fan to a position having a third angle with the rotation plane.

[0075] The first angle has a value range of 60° to 89°, the second angle has a value range of 30° to 59°, and the third angle has a value range of 1° to 29°.

[0076] The above operation steps can also be reversed, that is, when the slider 30 moves to the end of the slide rail 20, the reverse thrust fan can push the slider 30 to the head end of the slide rail 20, and the operation of the reverse thrust fan in this process conforms to the reverse operation of the above steps.

[0077] In a specific embodiment, the specific operation process of the present invention is as follows:

[0078] When the airborne combat device 40 is not firing, the blades of the reverse thrust fan are perpendicular to the rotation plane, and the reverse thrust fan rotates at a preset initial speed;

[0079] After the airborne combat device 40 fires, the first detection point is set at a position adjacent to the slider 30, and the slider 30 is detected to move backward, the propeller pitch adjustment device adjusts the blades of the reverse thrust fan to the first angle, and the control device increases the speed of the reverse thrust fan to the first speed;

[0080] When the slider 30 moves to the second detection point, the propeller pitch adjustment device adjusts the blades of the reverse thrust fan to the second angle and the control device increases the speed of the reverse thrust fan to the second speed;

[0081] When the slider 30 moves to the third detection point, the propeller pitch adjustment device adjusts the blades of the reverse thrust fan to a third angle and the control device increases the rotation speed of the reverse thrust fan to a third rotation speed.

[0082] When the slider 30 stops, the reverse thrust fan continues to work, so that the slider 30 passes through the third detection point, the second detection point and the first detection point in sequence, and then returns to the initial position and stops. The slider 30 needs to ensure that the speed is zero when it is in the initial position.

[0083] The embodiment of the present invention can reduce the recoil of the slider 30 and also quickly reset the slider 30, thereby facilitating subsequent shooting operations of the airborne combat device 40.

[0084] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
