Description

A towed secondary detonating cloud bomb and its precise war-fighting coordination method

technical field

The invention relates to the technical field of cloud explosive projectile design, in particular to a towed secondary detonation cloud explosive projectile and a method for precisely triggering and matching the same.

Background technique

Compared with other rockets, the cloud bomb has the characteristics of high energy utilization rate, large killing area and huge psychological deterrence. The use of the secondary detonation method can significantly improve the warhead power under the condition of the same charge and effectively improve the combat effectiveness of the weapon system. .

The secondary detonation cloud explosive bomb needs to separate the secondary detonation device from the projectile body in advance at a specific height, and then throw the cloud explosive agent to form a cloud aerosol. The secondary detonation device falls into the cloud again after the optimal delay time. To detonate to form a detonation. The pilot coordination method is mainly to solve the coupling problem between the secondary detonation device and the cloud after separation from the projectile, eliminate a series of spatial errors formed by the secondary detonation device and the cloud after separation, and ensure that the secondary detonation device is in the best condition. The delay time reliably falls into the cloud and detonates, and achieves the best damage effect.

The traditional secondary detonation cloud bomb launch coordination method is to separate the parachute. As shown in Figure 1, after the projectile reaches the top of the target, the warhead is separated from the projectile and the deceleration parachute is opened, and the parachute is lowered by the deceleration parachute. At the same time, the secondary detonation device is installed on the umbrella of the deceleration parachute, and the length of the parachute rope is adjusted according to the falling speed of the throwing point of the warhead to ensure that the secondary detonation device is fixed at the same time. falls into the cloud within the delay time.

However, using the traditional method of triggering and cooperating, the warhead needs to be separated from the projectile body. The separation of the projectile body will result in a complex structure design of the projectile body, and the separation process will also produce obvious ballistic disturbance to the warhead, and the warhead will be in an uncontrolled state after separation. , Many factors have greatly reduced the accuracy of the ammunition hit; at the same time, the deceleration parachute has poor wind resistance, and under windy conditions, it is difficult to predict the location of the combat camp with the parachute.

Detailed ways

The invention provides a towed secondary detonation cloud explosive bomb, the basic idea of which is that the rocket bomb is not separated, but the secondary detonation device is connected to the rocket bomb through a cable; the secondary detonation device is initially located in the bomb body. , when the predetermined height is reached, the secondary detonation device is thrown out of the projectile. After the secondary detonation device is thrown out of the projectile, it remains connected to the rocket through the cable. In the process of ejection and cable straightening, the secondary bullet will not have a significant impact on the trajectory and attitude of the rocket, so that the accuracy of the rocket will not be affected under the premise of ensuring the normal secondary detonation of the cloud bomb. .

The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 2 , the towed secondary detonation cloud explosive of the present invention includes a rocket and a secondary detonation device. The projectile body of the rocket is provided with an ejection opening (not shown in FIG. 2 ). In this embodiment, the ejection opening is preferably arranged on the side wall of the projectile body, so that the structure is simple. In practice the ejection port can also be located at the tail. A projectile device and a pay-off mechanism are installed in the rocket. Three control modules are also added to the rocket, which are the secondary detonation control module, the throwing control module and the release control module.

For example, the secondary detonation control module can be integrated in the proximity detection device, and the ejection control module and the payout control module can be integrated in the control platform.

The secondary detonator is connected to the rocket through a cable. In terms of structural connection, one end of the cable is connected to the body of the secondary detonation device, and the other end is connected to the pay-off mechanism; in terms of electrical connection, one end of the cable is connected to the controller of the secondary detonation device, and the other end is connected to the secondary detonation control module . The secondary detonation control module transmits a signal to the secondary detonation device through the wire embedded in the cable.

The throwing control module is used to control the secondary detonation device to be thrown out of the projectile through the throwing port. Using a projectile device to achieve projectile can improve the projectile success rate. The projectile device may eject the secondary detonation device by mechanical ejection or by means of a fire actuating device. In practical applications, only the opening can be designed, and the secondary detonation device can be moved out of the projectile body by using the change of the rocket's flight attitude and inertia.

The pay-off control module is used to control the pay-off mechanism, including controlling its pay-off length and pay-off speed, so as to cooperate with the delay described below to ensure that the secondary detonation device accurately falls into the cloud at the end of the delay , to reduce errors. The pay-off control module can also release the control cable gradually after the secondary detonating device ejects the projectile to maintain the stability of the secondary detonating device and avoid winding; and when the relative distance between the secondary detonating device and the rocket reaches a predetermined distance After the cable length is left, stop paying off.

The secondary detonation control module starts the delay timing after the rocket reaches the set cloud blasting agent throwing height and throws the cloud blasting agent, or controls the secondary detonation device to start the delay timing; after the timing reaches the specified delay time, the secondary detonation The detonating device falls into the cloud and detonates to form a detonation. In practice, the former control method is preferred, that is, after the rocket reaches the set height of the cloud blasting agent, the secondary detonation control module transmits the firing signal to the secondary detonation device through the wire embedded in the cable, and then the cloud explodes. The agent is thrown (can be controlled by rockets), and the secondary detonation device starts to delay timing after receiving the signal. After the specified delay time, the secondary detonation device falls into the cloud and detonates to form a detonation.

After the relative distance between the device and the rocket reaches the reserved cable length, the cable is straightened and no longer stretched, and the secondary detonation device no longer moves backward relative to the rocket, and falls together with the rocket.

Since the volume and weight of the secondary detonator are much smaller than those of the rocket, and the rocket is fully closed-loop controlled, the secondary detonator will not significantly affect the trajectory and attitude of the rocket during the ejection and cable straightening process. Impact.

After the cable is straightened, the rocket continues to fly towards the target. After reaching the set height of the cloud blasting agent, the detonation control module transmits the firing signal to the secondary detonation device through the wire embedded in the cable, and then the rocket throwing cloud explosives;

The secondary detonation device starts to delay the timing. After the specified delay time, the secondary detonation device falls into the cloud and detonates to form a detonation.
