Description

Multipurpose UAV interceptor

The claimed invention relates to aviation technology, in particular unmanned aerial vehicles (UAVs), designed to neutralize small air targets.

Small intruder drones are difficult to identify, their defeat by existing anti-aircraft weapons is economically inexpedient, electronic countermeasures have their limitations and are not always effective. The solution to this problem is UAV interceptors for kinetic impact on the intruder drone.

Known device quadrocopter "Interceptor" for the destruction of other drones, presented in 2019 by the military-technical startup Anduril Industries (Manufacturer's website https://www.anduril.com/news/2019/10/4/nbc-news-inside-anduril- the-startup-that-is-building-ai-powered-military-technology, screenshot date 1/16/2020). The "Interceptor" tracks, scanning the space with the help of a computer vision system, detecting a target, asks the human operator for permission to attack and then goes to contact interception.

The disadvantage of this device is that in a collision "Interceptor" can lose control and collapse when falling.

Known "Homing missile" (Patent RU2015151254 A, IPC F42B 15/01, 03/07/2018.), Containing a housing with a homing head and an electric jet propulsion unit (EJE), designed to intercept missiles and drones in the immediate vicinity of defense objects.

The disadvantage of a homing electric rocket is its one-time use, which leads to excessive costs for hitting relatively inexpensive drones on commercial platforms, long flight and monitoring of the protected area are not provided.

The closest analogue in technical essence is the DroneBullet interceptor device from the Canadian company AerialX (Manufacturer's website https://www.aerialx.com/defeat.shtml, screenshot date 01/16/2020). The interceptor has a compact cylindrical body with a striking part in the form of a reinforced nose fairing and four propeller-driven groups. Using a signal from the built-in camera, the operator aims the DroneBullet at the target, the collision of the interceptor and the intruder drone leads to their mutual destruction.

The disadvantages of this device include the fact that the remotely controlled by the operator and a small frontal projection DroneBullet can only be used against a sedentary target, the interceptor is used exclusively as a "kamikaze drone" with subsequent self-destruction, which poses a danger in crowded places, "disposable »Application is not economically feasible, it is impossible to confirm the results of the attack from the interceptor, as well as to continue neutralizing other intruder drones.

The objective of the present invention is the development of a reusable UAV interceptor, effectively striking by means of a kinetic strike against a small-sized air target, while the interceptor UAV does not lose the ability to execute the flight program and independently returns to base.

Another object of the present invention, in contrast to the analogue, is the development of a new design of the striking part, which allows the UAV body at the time of interception to be outside the contact collision zone with the target.

Another objective of the present invention, in contrast to the analogue, is to increase the chances of guaranteed target destruction due to the possibility of performing the striking part with a frontal projection area significantly exceeding the frontal projection area of the UAV body.

Another object of the present invention is to develop a new design of the striking part that allows the installation of a net for catching an intruder drone, while the net is clearly positioned in flight relative to the body due to the fact that the net is held on the striking part.

Another object of the present invention is to minimize critical overloads transmitted to the UAV interceptor body through the striker when colliding with an intruder drone.

The objective of the present invention is the ability to apply a balanced automation to compensate for the rollback impulse of the mobile after impact by means of counter-mass.

Another object of the present invention is the ability, regardless of the speed of convergence between the UAV interceptor body and the intruder drone, to selectively change, within known limits, the collision speed of the striking part with the intruder drone, thereby setting the level of subsequent target damage.

Another object of the present invention is the multipurpose purpose of the UAV-interceptor due to different modes of selective action on the target: from the complete destruction of the intruder drone due to the impact effect when intercepting at high speed, incapacitation and holding in the air by a piercing blow of the "harpoon" type, capture in the air without damaging the target due to the holding grid.

Other objects and advantages of the present invention will become more apparent in the description and drawings below.

The technical result is to expand the arsenal and functionality of UAV interceptors used to prevent unauthorized entry of intruder drones.

The specified technical result is achieved by the fact that the proposed multipurpose UAV-interceptor for kinetic impact by collision with a small-sized air target, consisting of a body for placing equipment and payload, a propeller, a landing gear, a control and navigation system, a target guidance system, while, at least one battering ram with an impact part is installed on the body as a payload, the battering ram is presented as a separate structural element and is movably connected to the body by means of an impact energy absorption device, the impact energy absorption device is represented by a hinge with a damping device, the impact part of the battering ram before collision with the purpose of protruding beyond the dimensions of the body at a distance F, the guidance system is made with the ability to intercept the target due to the contact intersection of the trajectory of the target movement with the trajectory of the striking part of the ram, protruding beyond the dimensions of the body, with this ohm, the guidance system, in addition, at the time of interception, provides a non-contact flight of the UAV-interceptor body close to the target at a distance R less than a distance F.

An interceptor UAV can be presented in the form of a multicopter, airplane, tiltrotor, flying wing, helicopter or other known device. The body is used to mount equipment and payload and can be represented by a glider, fuselage, frame, or other known device. If necessary, the UAV body can be transformable, for example, with folding frame beams with screws or a landing gear retractable into the fuselage, compartments for storing a ram can be made in the body or wing. In the embodiment of the H-shaped body, the ram is installed in the central part of the body and the ram can be rotated 360 degrees. In addition, support elements, guides, restraints, clamps, connections or other known elements can be made on the UAV body for installation of the shock energy absorption device. Preferably, for take-off and landing, a landing gear is made on the UAV body, or a parachute landing system is installed, or another known take-off and landing device is made. An electronic stabilization system, analysis of the operation of on-board devices, external loads can be installed in the housing, and the housing can be equipped with gyroscopes, a pressure sensor, an autopilot, an accelerometer, controllers, a sonar, a GPS receiver and other known devices. A radio beacon can be installed to recognize "friend or foe".

Small aerial targets are intruder drones of any type that fly unauthorizedly through a secured area or pose an imminent threat.

Preferably, the claimed device interacts with the main station, which plays the role of a command post that provides remote control and monitoring of the operation of an interceptor UAV, airspace monitoring and is equipped with systems for detecting and identifying small air targets.

At least one ram with a striking part is installed as a payload on the outer side of the body or in its compartment, the ram is movably connected to the body by means of an impact energy absorption device. To enhance the impact on the target, the ram can be additionally equipped with counterweights, weights and other known elements. The ram can be presented in the form of a closed frame inside which a mesh is installed, it can also perform the function of a landing gear, it can have additional detachable or movable connections with the body, The ram can additionally be equipped with electronic devices of various types: sensors, elements of the target guidance system, systems for suppressing target electronic devices (radio frequency, ultrasonic, electromagnetic and others), servo drives allowing to rotate the ram around its axis or change position relative to the body or open a telescopic ram, net tensioning devices and other known elements and their combinations. In other versions, a balancer can be installed - a load serving to balance the forces of inertia, connected to a movable ram. Preferably, the form of the ram should ensure the stability of its position relative to the UAV body without irreversible deformation under dynamic loads arising in flight and during target interception, the ram can be a composite of different elements, in the form of an independent part or in the form of a multi-piece structure, be hollow, or have a compartment for the net. The material from which the ram is made can be represented by metal, plastic, rubber or other known material.

The striking part of the ram directly serves for contact impact on the target and can be represented in the form of a bar with a sharp end part, a stand, a telescopic tube, a blade with a sharp edge, a rod with side-protruding striking elements, a weighting agent, in some embodiments, the striking part of a ram can be in the form of a replaceable module, can be completely or partially made of a fragile material, which, when intercepted, absorbs most of the impact energy and is destroyed at the same time, or be another known device.

The impact energy absorption device is designed to damp (dissipate) the main part of the collision energy of the ram with the target. Consists of at least a damper device and a movable connection made between the impact part of the ram and the UAV body. The movable connection can be represented by a hinge (cylindrical, ball, cardan), an elastic element (spring, elastic coupling, elastic plate), a flexible element (belt, cable), combined (two or more of the above devices) or other known device, which will provide the specified displacement of the ram relative to the body when the striking part of the ram collides with the target. After a collision with a target, the impact energy is partially spent on displacement of the ram relative to the body, and the damper finally absorbs and dissipates the impact energy. According to the method of absorbing the energy of impact, the device can belong to the following groups: frictional, hydraulic, elastomeric, from elastic elements, magnetic, combined (energy absorption occurs in two or more of the above methods) or other known devices.

In other embodiments, the impact energy absorption device can be represented by a balanced automation system that implements the principle of compensating for the rollback impulse of a battering ram, which is movable after impact, using counter-mass. The balanced automatics can be in the form of levers, gears, toothed racks or other known design, the counter-mass can be represented by a weighting agent or an item of equipment (for example, a battery).

Preferably, the ram can change its position relative to the body by means of an electromechanical drive, a stepper motor, a servo drive or other known device. A servo drive can consist of an electric motor with a gearbox, a sensor for the angle of rotation of the output shaft of the gearbox, a power supply unit and, by means of transmission mechanisms (belt, chain, gear, etc.), transfers movement to the driven element - a ram. Preferably, the servo drive interacts with a movable connection of the impact energy absorption device, for example, with a hinge made between the striking part of the ram and the UAV body, in some versions the servo drive can be an element of such a connection, in other versions the servo drive can be installed on the UAV body. On command, the servo can set the ram in different positions, for example, in the "flight" mode, the ram is placed along the hull or in the hull compartment, in the "intercept" mode, the ram moves as far as possible from the hull to the position for striking, in the "harpoon" mode the ram is directed by its own the sharp part on the target to capture it, in the "net" mode on the ram, the grid is deployed (if it is not previously installed) and, if necessary, the ram or UAV is turned by the plane of the stretched grid towards the target. Also, the servo drive can provide a change in the force of impact when a ram collides with a target, for example, by quickly switching from the "flight" mode to the "intercept" mode immediately before contact with the target. The ram position control unit is a variant of the controller that receives data from the UAV systems, connects to the flight control system and actively interacts with it. Based on them, commands are sent to the servo motors, telling them when and at what speed to move. The ram can be retracted into a compartment in the fuselage or on the wing, after which the compartment can be closed by flaps, which improves streamlining.

The battering ram can be used as an impact weapon for mechanical destruction of the target. To do this, it is installed permanently on the body or made with the possibility of automatic extension. Preferably, the ram is extended as far as possible from the hull at a conditional distance F. In this position, the striking part of the ram has a larger frontal projection area compared to the frontal projection of the hull, which will increase the chances of guaranteed target destruction, and also reduce the likelihood of collision of the UAV-interceptor hull with the target ...

The battering ram can be used to inflict a point defeat in the form of a stabbing blow of the "harpoon" type. Preferably, such a blow is delivered by the end element of the ram striking part installed beyond the dimensions of the body. Such an impact will immobilize the intruder drone, but at the same time keep it in the air in order to prevent the target from falling, for example, in crowded places.

The ram can interact with a flexible net to catch intruder drones. The net can be initially installed on a ram, made in the form of a frame, be attached to the ram on one of its sides, or be twisted into a tight roll on a rod that is rigidly or movably mounted on the ram or body and under the influence of a spring or servo drive the net opens, the net can be installed in a compartment made in a ram or a body, the mesh can be deployed by moving along the ramming guides, by moving the moving elements forming the ram body to the sides, by changing the position of the elements of the landing gear performing the role of a ram or interacting with another known ram way. Additionally, a servo drive can be installed to automate the unfolding of the mesh. Together with the interception of the grid, devices for suppressing the target electronics can be used (due to acoustic impact, interference in control, signal substitution, etc.). The ram, due to its rigid structure, interacts with the net for catching intruder drones, which will provide a clear positioning of the net relative to the body in flight and minimize the swaying of the net at high speeds. This solution outperforms the well-known free-hanging network interceptor drones.

Flight control and targeting is carried out with or without human participation in the control loop (in autonomous or remotely controlled mode), using machine vision, using artificial intelligence, or in another known way. The aiming task is to bring the ram closer to the target, in aligning their coordinates and is solved using various methods of targeting using a complex of interconnected devices. It includes the UAV body with its dynamic characteristics, a ram with a control system for its position relative to the body (in the variant of automatic ram advance), devices that determine the position of the target in space, information transmission systems, and others. A homing head (GOS) can be installed on an interceptor UAV, which receives the target's own radiation in the form of radio, radar, thermal (IR) radiation, reacts to the noise of propellers or other background. By processing the received radiation, the GOS issues signals to the autopilot. The guidance system is made with the ability to intercept the target due to the contact intersection of the trajectory of the striking part of the ram with the trajectory of the intruder drone, while the guidance system at the time of interception provides a contactless flight of the UAV body itself next to the intruder drone. This is achieved through adjustments to the flight control or is initially set by special algorithms in the target guidance program or in another way. Additional control algorithms can be introduced into the flight control system program that stabilize the position of the UAV body under shock loads after intercepting a target.

The claimed multipurpose UAV-interceptor works as follows: when the operator sends a command from the main station, the UAV-interceptor is activated and moves to the area where the intruder drone was seen. In the "flight" mode, the ram is placed in the hull compartment or along the hull to reduce aerodynamic drag. When deciding to attack the target, the servo drives the ram into the "intercept" mode: the ram on the articulated joint rotates, and its striking part extends beyond the dimensions of the body at a distance F. In this position, the ram has a larger frontal projection area, which increases the chances of guaranteed target hitting. The guidance system calculates the trajectory of movement so that the striking part of the battering ram would collide with the target, but at the same time the body must fly non-contact near the target at a distance R. If necessary, the servo can provide a change in the force of the impact when the ram collides with the target by quickly switching from the mode " flight "into the" intercept "mode immediately before contact with the target, that is, at this moment, the striking part of the ram moves towards the target faster than the UAV body itself moves. The collision with the target is perceived by the impact part of the ram, at the place of the movable connection, the ram is displaced relative to the body by means of the impact energy absorption device (rotation on the hinge, or due to bending of the flexible element, or due to deformation of the elastic element, or due to a combination of such devices) and when This damper dissipates the impact energy from the collision of the ram with the target, which leads to a decrease in the loads transmitted to the interceptor body. An interceptor UAV does not lose the ability to execute the flight program, it can record the result of the interception, if necessary, attack other targets and return to base on its own. If necessary, disable the target, but prevent it from falling to the ground, the UAV-interceptor in the "harpoon" mode extends beyond the dimensions of the hull and directs the sharp element of the striking part of the ram to the target, pierces the structure of the intruder drone and captures it. In the "net" mode, the net is deployed on the ram (for example, by extending the lever on the ram to which a part of the net is attached), the ram extends beyond the hull dimensions and, if necessary, the ram is turned by the plane of the stretched net towards the target. In this case, the intruder drone is neutralized, but not destroyed.

Thus, the claimed design provides an expansion of the arsenal and functionality of the interceptor drones.

Comparative analysis of the proposed device with the prototype allows us to conclude that the claimed multipurpose UAV-interceptor differs from the known one:

- installation on the body as a payload of at least one ram with a percussion part;

- execution of the ram in the form of a separate structural element;

- making a movable connection of the ram with the body by means of an impact energy absorption device;

- implementation of the impact energy absorption device in the form of a hinge with a damping device;

- installation before collision with the aim of the striking part of the battering ram, protruding beyond the dimensions of the body at a distance F;

- the implementation of the guidance system with the ability to intercept the target due to the contact intersection of the trajectory of the target movement with the trajectory of the striking part of the battering ram, protruding beyond the dimensions of the body;

- the implementation of the guidance system, which additionally provides a non-contact flight of the UAV-interceptor body close to the target at a distance R less than a distance F.

The claimed design provides:

- development of a reusable UAV interceptor, effectively striking by means of a kinetic strike against an airborne small-sized target, while the interceptor UAV does not lose the ability to carry out the flight program and independently returns to the base;

- development of a new design of the striking part, allowing the UAV body at the time of interception to be outside the contact collision zone with the target.

- increasing the chances of guaranteed target destruction due to the possibility of performing the striking part with the frontal projection area significantly exceeding the frontal projection area of the UAV body;

- development of a new design of the striking part, which ensures the installation of a net for catching an intruder drone, and at the same time the net is clearly positioned in flight relative to the body due to the fact that the net is held on the striking part;

- minimizing critical overloads transmitted to the UAV interceptor body through the striking part in a collision with an intruder drone;

- the ability to apply balanced automation to compensate for the recoil impulse of moving parts after impact with the help of anti-mass;

- the ability, regardless of the speed of convergence between the UAV interceptor body and the intruder drone, to selectively change the collision speed of the striking unit with the intruder drone, thereby setting the level of subsequent target damage;

- multi-purpose UAV interceptor due to different modes of selective impact on the target: from the complete destruction of the intruder drone due to the impact effect when intercepting at high speed, incapacitation and holding in the air with a piercing blow of the "harpoon" type, capture in the air without damage targets due to the retention mesh.

The foregoing allows us to conclude that the claimed set of features characterizes a new design solution, previously unknown from the prior art, and therefore the claimed invention meets the criterion of "novelty".

Since the proposed design of a multipurpose UAV-interceptor and the achieved technical result do not explicitly follow from the state of the art, it can be concluded that the proposed solution meets the criterion of "inventive step".

The proposed design of a multipurpose UAV-interceptor can be manufactured using structural details known in the art and known technologies. The possibility of industrial use of the proposed multipurpose UAV-interceptor allows us to conclude that it meets the criterion of "industrial applicability".

Examples of a specific implementation of a multipurpose UAV-interceptor are described below with reference to the accompanying drawings.

Device 1 works as follows: when the command is given, the UAV-interceptor moves to target 12. In the “flight” mode, the ram 5 is placed along the body 2 (position “A” is not shown in the figure). Before attacking target 12, the servo drive 11 switches the ram 5 to the "intercept" mode: the ram on the pivot support 7 rotates and its striking part 6 is set as far as possible from the body (distance F) to the strike position (position "B"). In position "B" the ram has a larger frontal projection area, which increases the chances of guaranteed target destruction. The guidance system 4 calculates the trajectory of movement so that the striking part 6 would collide with the target 12, but at the same time the body 2 should fly non-contact next to the target 12 at a distance R. The collision is perceived by the striking part 6, and from the impact the ram starts to move relative to the body 2, by means of the device for absorbing the energy of the impact, the ram is rotated on the hinge 7 and at the same time the damper shock absorber 8 dissipates the energy of the impact. If necessary, the UAV-interceptor 1 in the "harpoon" mode attacks the target with a sharp element 10 and captures it (not shown).
