Description

Active protection system of chariot

Technical Field

The invention belongs to the technical field of vehicle protection, and particularly relates to an active protection system of a combat tank.

Background

For a chariot, the body of the chariot is required to face the individual weapon and the various calibers such as the rocket tube for multi-directional striking and damage. There are three general protection strategies.

First, passive protective armor is installed. At present, some armored vehicles resist striking, disperse and deflect explosion shock waves and reduce pressure on vehicle bottom plates by installing energy-absorbing armors such as high-strength armored steel, ceramics, glass fibers, aluminum alloy and the like on vehicle bodies and gun towers. The energy-absorbing armor is additionally arranged on the vehicle body, has a certain protection effect, but has heavy quality and complex material structure, and reduces the trafficability and the fighting performance of the armored vehicle.

Second, an active safeguard strategy. The detection device is used for actively obtaining the motion characteristics of the attacking ammunition, then the computer is used for controlling the countermeasure device such as an intercepting ammunition to counteract and destroy the attacking ammunition, so that the attacking ammunition cannot directly hit a protected target, the intercepting ammunition destroys the attacking ammunition through hard killing, protection is provided for an armored vehicle, the intercepting ammunition needs to occupy the space on a gun turret, the installation and protection positions are limited, 360-degree all-directional protection is difficult to achieve, and the installation of other functional parts is influenced. In addition, the number of interceptor projectiles is limited.

And thirdly, externally hanging grid armors on the whole body of the chariot. The grids of the metal framework can clamp and clamp the attacking rocket projectile so as to reduce the damage to the vehicle body, and the metal framework can be used for resisting the rocket projectile at the hollow blasting warhead, such as a armor-breaking projectile, but can not resist the kinetic energy armor-piercing projectile. The grid armor has the advantages of simplicity, lightness and weakness, and has the defects that the installation of other functional parts is obviously influenced because the grid armor is externally hung, and the installation and protection positions are limited; and is ineffective for kinetic armor piercing projectiles.

Therefore, it is desirable to develop a simpler and more effective combat vehicle protection system.

Disclosure of Invention

The invention aims at the technical problems that: the three existing protection strategies have the defects of heavy quality, complex structure, influence of installation space on the function exertion of other parts, low interception efficiency and the like, and a simpler and more effective combat tank protection system needs to be invented.

The technical scheme adopted by the invention is as follows: when a rocket projectile or a guided missile attacks, a rotating barrier is arranged between the vehicle body and an assailant, and the rotating barrier is contacted, collided and blocked, so that the posture and the track of the assailant are changed, the original blasting effect is lost, and the vehicle body is protected.

The invention comprises the following technical characteristics: an active protection system for a war chariot is arranged on a chariot body and comprises a detection radar, a control system and a collision mechanism.

The detection radar is controlled to emit and receive radar waves, motion characteristic data of the incoming ammunition are obtained in an active mode, and the motion characteristic data are transmitted to the control system; the control system controls the detection radar and the collision mechanism, calculates and analyzes data transmitted by the detection radar, generates a defense countermeasure and drives the collision mechanism to resist the incoming ammunition.

The collision mechanism comprises a base, a mechanical arm, a connecting shaft, a motor and blades.

The base is arranged on the vehicle body and connected with and supports the mechanical arm; the base can be controlled to rotate around the central shaft of the base in a fixed axis manner.

One end of the mechanical arm is connected with the base, and the other end of the mechanical arm is connected with and supports the blade through a connecting shaft; the position and the posture of the blade can be adjusted by the mechanical arm through self adjustment.

The connecting shaft is fixedly connected with and supports the blades.

The motor is arranged between the mechanical arm and the connecting shaft and drives the connecting shaft and the blades to rotate.

The blades are controllably rotatable to form a rotating barrier. So as to contact, collide and intercept the coming ammunition and protect the vehicle body.

The mechanical arm comprises three connecting rods and three connecting points, namely a connecting rod I, a connecting rod II, a connecting rod III, a connecting point I, a connecting point II and a connecting point III; the three connecting rods are sequentially connected end to end through connecting points, the first connecting rod is rotatably connected with the base through the first connecting point, the second connecting rod is rotatably connected with the first connecting rod through the second connecting point, and the third connecting rod is rotatably connected with the second connecting rod through the third connecting point; the first connecting rod comprises a front end and a rear end, and the rear end of the first connecting rod can rotate around an axle center of the first connecting rod as a fixed shaft; the second connecting rod comprises a front end and a rear end, and the rear end of the second connecting rod can rotate around the axis of the second connecting rod as a fixed axis; the control center controls the movement of the first connecting rod, the second connecting rod, the third connecting rod, the first connecting point, the second connecting point and the third connecting point, so that the position and the posture of the blade are adjusted.

The blades are symmetrically arranged by taking the axis of the connecting shaft as a center.

The blades are made of composite materials (such as alloy steel, carbon fiber and Kevlar fiber) so as to increase toughness and intercept the incoming ammunition by collision.

The blades comprise two or more cotyledons, and the angles of the cotyledons are uniformly arranged; preferably three cotyledons.

The two or more cotyledons are fixedly connected.

Alternatively, the two or more cotyledons may be detachable.

The vehicle body comprises a turret, the turret is rotatably arranged on the upper portion of the vehicle body, and the collision mechanism is mounted on the turret and can rotate together with the turret.

The active protection system of the chariot comprises two or more collision mechanisms.

The scheme also provides a war chariot which comprises the active protection system of the war chariot.

The scheme is characterized in that appropriate components are arranged at appropriate positions, for example, a power supply provides electricity for the detection radar, the control system and the collision mechanism, the electric wire and the data wire are connected with the detection radar, the control system and the collision mechanism, and the electric wire and the data wire can be connected with the control system, the base and the mechanical arm to achieve the connection shaft and the motor.

The invention has the beneficial effects.

1) The scheme forms a rotary barrier between the attacking ammunition such as a rocket projectile and the vehicle body through the rotation of the blades. When an incoming rocket projectile enters the rotating barrier, the blades transversely collide the rocket projectile on the side in the direction perpendicular to the trajectory of the incoming rocket projectile, so that the trajectory of the rocket projectile is changed by small force, the head of the rocket projectile cannot attack the vehicle body according to the design, the incoming ammunition cannot be detonated normally, and the vehicle body is protected.

2) The scheme can pre-adjust the mechanical arm and the adjusting blades to proper positions and postures according to needs, and a rotary barrier protection is arranged at a possible incoming position in advance. The first defense positions of the vehicle body in different environments are different, for example, when the helicopter is prevented from being attacked, the first protection position is the vehicle roof, and when the helicopter passes through a village and other complex road sections, the first protection position is the side body of the vehicle.

3) Compared with the existing passive protection armor, the passive protection armor has the advantages that the blades form a rotating barrier, heavy armor is not needed, the requirement on materials is low, and the passive protection armor is beneficial to the trafficability and the fighting performance of a combat tank.

The advantage of the initiative protection strategy of this scheme relative present transmission interception bullet lies in, position and the gesture that this scheme can be adjusted as required to can be dynamic strengthen the protection in key position, present initiative protection strategy can only set up the interception bullet in fixed position and influence the installation of other functional unit, so, this scheme is better than present initiative protection strategy effect, and is more convenient. The scheme protects the vehicle body through collision instead of explosion, does not need to consume interception bullets, and is more durable compared with the existing active protection strategy.

The scheme is different from the scheme that the distance of the external hanging body of the grid armor is limited, and the mounting position of the grid armor is limited and influences the mounting of other functional parts. This scheme can not only resist broken first bullet, can also resist kinetic energy and wear first bullet.

Detailed Description

It should be noted that, in the present invention, the technical features of the embodiments and the examples may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Preferred embodiments of the present invention will be described in further detail with reference to fig. 1 to 5.

As shown in figures 1 and 2, the active protection system of the chariot comprises a detection radar 22, a control system 20 and a collision mechanism 30. The impact mechanism 30 includes a base 32, a mechanical arm 40, a connecting shaft 34, a motor 36, and a blade 38.

The detection radar 22 actively detects the motion characteristics of the attacking ammunition, such as the rocket projectile 62, and transmits the obtained motion characteristic information to the control system 20, and the control system 20 adjusts the mechanical arm 40 to enable the blade 38 to be in the required proper position and posture through analysis and calculation so as to collide and intercept the attacking ammunition and protect the vehicle body 10. The vehicle body 10 comprises a turret 12, the turret 12 is rotatably arranged on the upper portion of the vehicle body 10, and the collision mechanism 30 is mounted on the turret 12 and can rotate together with the turret 12. Detection radar 22 is provided on the turret 12 for rotation with the turret 12 to better detect incoming ammunition and also to avoid interfering with the rotation of the turret 12.

The impact mechanism 30 is disposed on the turret 12 and is rotatable with the turret 12 to better intercept incoming ammunition and also to avoid impeding the rotation of the turret 12. The base 32 is rotatably connected to the turret 12, one end of the mechanical arm 40 is rotatably connected to the base 32, the other end of the mechanical arm is connected with and supports the blades 38 through the connecting shaft 34, the mechanical arm 40 can adjust the blades 38 to a required proper position and posture through self adjustment, the motor 36 is arranged between the mechanical arm 40 and the connecting shaft 34, the connecting shaft 34 and the blades 38 are driven to rotate around the axis of the connecting shaft 34 as a fixed shaft, a rotating barrier 60 is formed, and therefore the bullet ammunition is collided and intercepted, and the vehicle body 10 is protected. In fig. 1, the active protection system of a combat tank is provided with two sets of collision mechanisms 30, which are respectively located at the left and right sides of the turret 12. The left impact mechanism 30 has been adjusted above the vehicle body 10 such that the high speed rotating blades 38 impact an incoming projectile 62 and the blades 38 sweep laterally across the incoming projectile 62 from the sides of the projectile 62, causing the projectile 62 to change trajectory 64 and fall to the ground nearby, thereby protecting the turret 12, which is beneficial for preventing helicopters and the like from attacking the vehicle body 10 from the top. The right side impact mechanism 30 has been adjusted to the right side of the body 10 ready for war, with the high speed rotating vanes 38 forming a rotating barrier 60 to impact and intercept right side incoming ammunition, which is beneficial to protect the vehicle against side-by-side attacks by rocket projectiles 62 as the vehicle travels through complex areas (e.g., villages). The multiple sets of collision mechanisms 30 are used simultaneously, so that the chariot can be protected simultaneously in different directions without dead angles.

The vanes 38 are arranged symmetrically about the connecting shaft 34.

The vanes 38 are made of a composite material (e.g., alloy steel, carbon fiber, kevlar fiber) to add a more flexible impact blocking of incoming ammunition.

Fig. 2 is a schematic system block diagram of an active protection system for a combat vehicle, in which a control system 20 controls the operation of a detection radar 22 and a collision mechanism 30. The detection radar 22 actively obtains the motion characteristic data of the incoming ammunition, transmits the data to the control system 20, the control system 20 generates a defense countermeasure according to the data, adjusts the base 32 and the mechanical arm 40, adjusts the vanes 38 to a required proper position and posture, enables the vanes 38 to be positioned between the incoming ammunition and the vehicle body 10, and enables the vanes 38 to be perpendicular to the track 64 of the incoming ammunition, namely the required proper position and posture; the control system 20 drives the blades 38 to rotate at a high speed through the motor 36 to generate enough momentum to form a rotating barrier 60, when the incoming ammunition collides with the rotating blades 38, the blades 38 transversely sweep the incoming ammunition from the side, and the momentum of the blades 38 is transferred to the incoming ammunition, so that the incoming ammunition deviates from the original track 64, particularly the warhead of the incoming ammunition, and cannot enter the vehicle body 10 according to the design of the incoming ammunition.

As shown in fig. 3, the robot arm 40 includes three links and three connection points, i.e., a link one 42, a link two 44, a link three 46, a connection point one 48, a connection point two 50, and a connection point three 52; the three connecting rods are sequentially connected end to end through connecting points, the first connecting rod 42 is rotatably connected with the base 32 through a first connecting point 48, the second connecting rod 44 is rotatably connected with the first connecting rod 42 through a second connecting point 50, and the third connecting rod 46 is rotatably connected with the second connecting rod 44 through a third connecting point 52; wherein, the first connecting rod 42 comprises a front end 422 and a rear end 424, the rear end 424 of the first connecting rod 42 can rotate 428 around the axle center of the first connecting rod 42 relative to the front end 422; the second connecting rod 44 comprises a front end 442 and a rear end 444, and the rear end 444 of the second connecting rod 44 can rotate 448 around the axle center of the second connecting rod 44 relative to the front end 442; the control center controls the movement of link one 42, link two 44, link three 46, connection point one 48, connection point two 50, and connection point three 52, thereby adjusting the position and attitude of the blade 38.

The first connecting rod 42, the second connecting rod 44, the first connecting point 48, the second connecting point 50 and the third connecting point 52 are respectively provided with a driving mechanism so as to drive the first connecting rod 42, the second connecting rod 44, the first connecting point 48, the second connecting point 50 and the third connecting point 52 to complete respective movement actions, for example, a servo motor 426 is arranged in the first connecting rod 42 and is controlled to drive the rear end 424 of the first connecting rod 42 to rotate 428 relative to the front end 422; a servo motor 446 is arranged in the second connecting rod 44 and is controlled by the servo motor 446 to drive the rear end 444 of the second connecting rod 44 to rotate 448 relative to the front end 442; the first connecting point 48 is provided with a servo motor (not shown) controlled to drive the first connecting rod 42 to rotate relative to the base 32; the second connecting point 50 is provided with a second servo motor controlled driving connecting rod 44 which rotates relative to the first connecting rod 42; the third connecting point 52 is provided with a servo motor controlled driving link three 46 to rotate relative to the second link 44.

The base 32 is rotatably connected to the turret 12, a servo motor 326 is disposed in the base 32, and the servo motor 326 is controlled to drive the base 32 to rotate 328 around its central axis, i.e. to rotate 328 relative to the turret 12. The base 32 and the robotic arm 40 are controlled to rotate to adjust the blade 38 to the proper position and attitude.

As shown in fig. 4, the blade 38 is composed of three cotyledons 382, and the three cotyledons 382 are arranged at an even angle.

More cotyledons 382, with the advantage that the blades 38, at the same rotation speed, can more easily collide with, intercept, or intercept an incoming ammunition, with the disadvantage of increasing the complexity of the system.

As shown in FIG. 5, three cotyledons 382 are detachable. When the operation is stopped, the three cotyledons 382 are disassembled and stacked together, so that the maintenance is convenient and the occupied space is reduced. And also facilitates possible wear and tear of the cotyledon 382 upon impact with incoming ammunition for replacement.

For example, the flying speed of the existing rocket projectile is usually between 100 m/s and 300 m/s, in the embodiment, the barrier 60 which is formed by rotating the three cotyledons 382 at 50 r/s rotates is adopted, and the rocket projectile 62 can completely contact and collide with the rocket projectile 62 with the length of more than 1 m and the flying speed of within 300 m/s. However, the probability of contact and collision can only be about 1/3 for ammunition with higher flying speed, such as cannonball with flying speed more than 900 m/s. Therefore, the scheme is designed for weapons such as defense rocket projectiles and has certain probability interception effect on high-speed incoming ammunition such as shells.

It will be appreciated that the present example also includes a power source, which may be disposed within the vehicle body 10, and electrical wires, which provide power to various components, including the detection radar 22, the control system 20, the impact mechanism 30; the wire and data lines connecting the detection radar 22, the control system 20, the impact mechanism 30, the wire and data lines running along the control system 20, the base 32, the robotic arm 40 to the connecting shaft 34 and the motor 36; this is a disclosure technique as would be understood by one skilled in the art.
