Description

Technical Field

[0001] The invention belongs to the technical field of fuel-air explosive warheads, and in particular relates to a terminal-separated secondary detonation fuel-air explosive bomb fuze-warhead matching control method. Background Art

[0002] The secondary detonation type of cloud-burst warhead is a type of warhead that is filled with cloud-burst agents. The cloud-burst agent is scattered by the primary fuze, diffused to form a cloud, and then the cloud is detonated by the secondary detonation to form a cloud explosion. Its action process is divided into two parts: scattering cloud-burst agents and secondary detonation, fuze-warfare matching. At present, the traditional fuze-warfare matching methods include two types: using parachutes to slow down and placing secondary detonators on the top of the parachute, and throwing multiple secondary detonators at the end of the cloud-burst bomb. The disadvantages of these two types of fuze-warfare matching methods are: (1) the applicable falling speed is usually no more than 100m / s, which cannot be applied to high-falling speed platforms such as rockets and missiles; (2) it cannot adapt to the long delay requirements of cloud-burst diffusion of large-yield warheads; (3) the detonation reliability is poor and is easily affected by the environmental factors of the landing point. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] The technical problem to be solved by the present invention is how to provide a terminal separation type secondary detonation fuel-air explosive bomb fuze-war matching control method to solve the problem of secondary detonation fuze-war matching of fuel-air explosive warhead.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present invention proposes a terminal separation type secondary detonation fuel-air explosive bomb ignition and warhead matching control method, the ignition and warhead matching control method is implemented based on the ignition and warhead system, the ignition and warhead system includes: a deceleration parachute, a secondary detonation cabin, a separation device, and a fuel-air explosive warhead;

[0007] The deceleration parachute is arranged at the tail and connected to the secondary detonation cabin, the other side of the secondary detonation cabin is connected to the cloud-explosive warhead, the separation device is arranged inside the cloud-explosive warhead, and the ignition-warhead matching control method specifically includes the following steps:

[0008] Step 1: When the end of the cloud-explosive warhead reaches the predetermined height, a delay time is set for the first cloud-explosive warhead fuse, which is recorded as ΔT1, and a delay time is set for the second detonation cabin, which is recorded as ΔT2. At the same time, the cloud-explosive warhead is separated from the second detonation cabin by a separation device. The cloud-explosive warhead continues to fly forward, and the second detonation cabin is connected to a deceleration parachute to decelerate the flight;

[0009] Step 2: The primary cloud-explosive warhead fuze explodes at the predetermined delay time, scattering the cloud-explosive agent to form a cloud. The cloud formation time is recorded as ΔT. At the same time, the secondary detonation cabin continues to move downward.

[0010] Step 3: When the secondary detonation capsule falls into the cloud in step 2 and detonates according to the predetermined delay time, a cloud explosion is formed, which damages the target.

[0011] The relationship between the delay time ΔT1 of the cloud-explosive warhead fuse binding, the delay time ΔT2 of the secondary detonation chamber binding and the cloud formation time ΔT is shown in formula (1):

[0015] Among them, v1 is the speed of the front-end cloud-explosive warhead, v2 is the speed of the secondary detonation cabin, and ΔL is the displacement distance of the cloud within ΔT time.

[0016] (III) Beneficial effects

[0017] The present invention proposes a terminal separation type secondary detonation fuel-air explosive bomb fuze-war matching control method, which can give the bomb-parachute separation height, primary fuze delay time, and secondary fuze delay time according to the terminal flight speed of the fuel-air explosive bomb, cloud size, and optimal cloud delay requirements, so that the secondary detonation device can detonate the cloud under the optimal time and space conditions to maximize the cloud explosion power. The fuze-war matching control method can adapt to supersonic conditions, and the process action time is milliseconds, which can effectively reduce environmental interference and improve reliability; in addition, the method can achieve a maximum secondary detonation delay time of more than 300ms, which can be applied to large-yield fuel-air explosive warheads.

[0027] Step 1: When the end of the cloud-explosive warhead reaches the predetermined height, a delay time is set for the first cloud-explosive warhead fuse, which is recorded as ΔT1, and a delay time is set for the second detonation cabin, which is recorded as ΔT2. At the same time, the cloud-explosive warhead is separated from the second detonation cabin by a separation device. The cloud-explosive warhead continues to fly forward, and the second detonation cabin is connected to a deceleration parachute to decelerate the flight;

[0028] Step 2: The primary cloud-explosive warhead fuze explodes at the predetermined delay time, scattering the cloud-explosive agent to form a cloud. The cloud formation time is recorded as ΔT. At the same time, the secondary detonation cabin continues to move downward.

[0029] Step 3: When the secondary detonation capsule falls into the cloud in step 2 and detonates according to the predetermined delay time, a cloud explosion is formed, which damages the target.

[0030] The relationship between the delay time ΔT1 of the cloud-explosive warhead fuse binding, the delay time ΔT2 of the secondary detonation chamber binding and the cloud formation time ΔT is shown in formula (1):
