The secondary detonation cloud detonation bomb needs to separate a secondary detonation device from a bomb body in advance at a specific height, then cloud detonation agents are scattered to form cloud aerosol, and the secondary detonation device falls into a cloud cluster again after the secondary detonation device is delayed for the optimal time to detonate and form detonation. The cooperation method of the priming and the fighting mainly solves the coupling problem between the separated secondary priming device and the cloud cluster, eliminates a series of space errors formed by the separated secondary priming device and the cloud cluster, ensures that the secondary priming device reliably falls into the cloud cluster and detonates in the optimal delay time, and achieves the optimal damage effect.
The traditional secondary detonation cloud blasting bomb warfare cooperation method is that a separation parachute opening mode is adopted, as shown in figure 1, after a bomb body reaches the upper part of a target, a warhead is separated from the bomb body and a parachute is opened, the falling speed of the cloud blasting warhead is reduced through the parachute, and the attitude of the warhead is adjusted; meanwhile, the secondary detonating device is arranged on the canopy of the speed-reducing parachute, the length of the parachute rope is adjusted by combining the falling speed of the scattering point of the warhead, and the secondary detonating device is ensured to fall into the cloud cluster within fixed delay time.
However, by adopting the traditional approach, the warhead needs to be separated from the projectile body, the projectile body separation can cause the structural design of the projectile body to be complex, the separation process can also generate obvious ballistic disturbance to the warhead, and the warhead is in an uncontrolled state after separation, so that the ammunition hitting precision is greatly reduced due to various factors; meanwhile, the wind resistance of the speed reducing umbrella is poor, and the drop point of the warhead with the umbrella is difficult to predict under windy conditions.

Detailed Description
The invention provides a dragging type secondary detonation cloud bomb which is basically characterized in that a secondary detonation device is connected with a rocket bomb through a cable instead of a rocket bomb separating device; the secondary detonating device is initially positioned in the bomb body, and is thrown out of the bomb body when reaching a preset height. And after the secondary detonating device is thrown out of the projectile body, the secondary detonating device is connected with the rocket projectile through the cable. The secondary bullet can not obviously influence the trajectory and the posture of the rocket projectile in the processes of throwing and straightening the cable, so that the hitting precision of the rocket projectile is not influenced on the premise of ensuring the normal secondary detonation of the cloud blasting projectile.
The invention is described in detail below by way of example with reference to the accompanying drawings.
Referring to fig. 2, the towed secondary detonation cloud detonation cartridge of the invention comprises a rocket cartridge and a secondary detonation device. The projectile body of the rocket projectile is provided with a throwing port (not shown in fig. 2), and the throwing port is preferably arranged on the side wall of the projectile body in the embodiment, so that the rocket projectile is simple in structure. In practice the ejection port may also be located at the tail. The rocket projectile is internally provided with a projecting device and a paying-off mechanism. The rocket projectile is also internally provided with three control modules which are respectively a secondary detonation control module, a throwing-out control module and a discharge control module. The three control modules can be arranged separately or integrated in a control device for rocket projectile reasons. For example, the secondary detonation control module may be integrated into the proximity detection device, and the ejection control module and the pay-off control module may be integrated into the control platform.
The secondary detonating device is connected with the rocket projectile through a cable. When the structure is connected, one end of the cable is connected with the body of the secondary detonating device, and the other end of the cable is connected with the pay-off mechanism; and one end of the cable is connected with the controller of the secondary detonation device, and the other end of the cable is connected with the secondary detonation control module. And the secondary detonation control module transmits signals to the secondary detonation device through a wire pre-buried in the cable.
And the ejection control module is used for controlling the secondary detonating device to be ejected out of the projectile body through the ejection port. The casting device is adopted to realize casting, so that the casting success rate can be improved. The ejection device can eject the secondary detonating device in a mechanical ejection or firer actuating device mode. In practical application, only the opening can be designed, and the secondary detonating device is moved out of the projectile body by utilizing the change of the flying attitude of the rocket and inertia.
And the pay-off control module is used for controlling the pay-off mechanism, and comprises a pay-off length and a pay-off speed which are controlled, so that the secondary detonating device is matched with the delay, the secondary detonating device is ensured to accurately fall into the cloud cluster when the delay is finished, and the error is reduced. The paying-off control module can also control the cable to be gradually paid out after the secondary detonating device throws out the projectile body, so that the stability of the secondary detonating device is kept, and the winding is avoided; and stopping paying off after the relative distance between the secondary detonating device and the rocket projectile reaches the reserved cable length.
The secondary detonation control module starts time delay timing after the rocket projectile reaches the set cloud detonation agent scattering height and scatters the cloud detonation agent, or controls a secondary detonation device to start time delay timing; and after the timing reaches the specified delay time, the secondary detonating device falls into the cloud cluster, and the detonation is formed by detonation. In practice, the former control mode is preferred, that is, after the rocket projectile reaches the set cloud blasting agent scattering height, the secondary blasting control module transmits the firing signal to the secondary blasting device through the wire pre-embedded in the cable, then the cloud blasting agent is scattered (can be controlled by the rocket projectile), the secondary blasting device starts delay timing after receiving the signal, and after the specified delay time, the secondary blasting device falls into the cloud cluster and is blasted to form detonation.
The accurate combat triggering cooperation method based on the dragging type secondary detonation cloud detonation bomb comprises the following steps:
and after the rocket projectile carries the secondary detonating device to the upper part of the target, the secondary detonating device is thrown out of the rocket projectile from the projectile body along the lateral direction by the projectile device at a specified height.
The secondary detonating device is connected with the rocket projectile through the cable, moves towards the rear of the rocket projectile under the action of pneumatic power, the projectile body is gradually released from the cable under the action of the pay-off mechanism, after the relative distance between the secondary detonating device and the rocket projectile reaches the reserved cable length, the cable is straightened and does not extend any more, and the secondary detonating device does not move backwards relative to the rocket projectile and falls along with the rocket projectile.
Because the volume and the weight of the secondary detonating device are much smaller than those of the rocket projectile, and the whole closed loop of the rocket projectile is controlled, the secondary detonating device can not obviously influence the trajectory and the posture of the rocket projectile in the processes of throwing and straightening the cable.
After the cable is straightened, the rocket projectile continuously flies towards a target, after the set cloud blasting agent throwing height is reached, the detonation control module transmits a firing signal to the secondary detonation device through a lead pre-embedded in the cable, and then the rocket projectile throws the cloud blasting agent;
and the secondary detonating device starts delay timing, falls into the cloud cluster after specified delay time, and is detonated to form detonation.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
