[0030] Example

[0031] like Figure 1 As shown, the present invention provides a distributed fuze system with adaptive detonation, including a power supply and interface module, a detonation control module, a detonation module and an explosion sequence.

[0032] The power supply and interface module is the energy device of the fuze.

[0033] The detonation control module is used to adaptively adjust the detonation time and position. The detonation control module includes a database, an environment detection controller, a state controller, a safety system and a detonation controller. The database and the environment detection controller are connected to the state controller and the safety system, and the state controller and the safety system are connected to the detonation controller.

[0034] The detonating module, including the high-voltage ignition unit, is used to formally detonate the fuze.

[0035] The explosion sequence, including detonators, boosters and main charges, is used to trigger the explosion of the main charge of the warhead.

[0036] The database includes: an environmental database and a target database established on the basis of a large amount of range experiment data, laboratory test data and simulation data.

[0037] The environment detection controller is used to detect and analyze the environment and the target to obtain the environment status information and the target status information, and input it into the status controller and the safety system.

[0038] The state controller is used to combine and analyze the target state information with the database, obtain the target state function and input it into the detonation controller.

[0039] The target state function includes the target position function, the target speed function, the target orientation function and the target distance function.

[0040] Target position function:

[0041] Assume that the position of the target in three-dimensional space can be expressed by coordinates (x t ,y t ,z t ), and these coordinates are functions of time. For example, in a plane rectangular coordinate system (ignoring the height z), the target position can be expressed by the following formula:

[0042] x t =x0+v xt t;

[0043] y t =y0+v yt t;

[0044] Among them, (x0, y0) is the initial position of the target, v xt and v yt They are the velocity components of the target in the x and y directions, x t and t They respectively represent the x-coordinate and y-coordinate of the target position in the plane rectangular coordinate system.

[0045] Target speed function:

[0046] The target velocity vector is:

[0047]

[0048] Among them, v zt Indicates the speed of the target in the z direction.

[0049] The speed can be calculated using the following formula:

[0050]

[0051] The direction of the target velocity can be represented by direction cosines. For example, in a plane, the velocity direction is θ with respect to the positive direction of the x-axis. t The angle meets:

[0052]

[0053] Target orientation function:

[0054] In the plane case, with the torpedo as the reference point, the target's azimuth angle α can be calculated by the following formula:

[0055]

[0056] Where (x r ,y r ) is the position of the torpedo.

[0057] In three-dimensional space, information such as pitch angle also needs to be considered, and the calculation of orientation will be more complicated, usually involving spatial geometric relationships and trigonometric functions.

[0058] Target distance function:

[0059] The distance between the torpedo and the target is:

[0060]

[0061] In three-dimensional space, this distance function is also a function of time, because the positions of the target and the torpedo are changing with time, z t Indicates the coordinate of the target in the z direction.

[0062] The safety system, as the insurance mechanism of the fuze, is used to release the insurance mechanisms one by one through the environmental information input by the environmental detector.

[0063] The detonation controller is used to compare the input target state function with the damage effectiveness function in the database, determine the maximum time and position of the damage effectiveness, and output the detonation command.

[0064] Damage efficiency function J R (t) is:

[0065]

[0066] in, is the nonlinear damage function, θ r (t) is the damage function parameter, L(·) is the damage correction function, S D (t) is the projectile state function, t d Indicates the dynamic delay of the fuze.

[0067] Reference Figure 2The present invention also discloses a damage calculation method for a distributed fuze system with adaptive detonation, comprising the following steps:

[0068] S01. Establish environment database and target database.

[0069] S02. Detect target information and its surrounding environment information through the environment detection controller, and input it into the state controller and the safety system.

[0070] S03. Analyze the target database of the information inputted from the environment detection controller to obtain the target state information and the target state function, and input them into the detonation controller.

[0071] S04. derive the status information of the fuze by analyzing the information inputted into the environment detection controller in combination with the environment database, and release the fuses one by one.

[0072] S05. By analyzing the status information of the fuze and the status information of the target and comparing them with the damage effectiveness function in the detonation controller, the maximum time and position of the damage effectiveness are determined, and a detonation command is output.

[0073] S06. After completing the functional test, perform structural numerical simulation on the fuze, and calculate the power characterization parameters by combining theoretical analysis and empirical formulas to obtain a fuze structure that maximizes the destructive power.

[0074] Therefore, the present invention adopts the above-mentioned distributed fuze system with adaptive detonation and its damage calculation method, which can realize adaptive damage control of explosion point, detonation direction, detonation time and damage mode.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
