AI Technical Summary
The lack of effective ground testing methods in the current technology to verify the delayed detonation time of the target fuze for the dynamic penetration strength of the guided penetrating explosive projectile leads to unreasonable determination of the delayed detonation time of the fuze in flight tests. This may result in the warhead detonating prematurely or beyond a certain distance inside the target, thus failing to exert its optimal destructive power.
A test system for the delayed detonation time of a target fuse for a dynamic penetration strength projectile was designed. The system includes a detonation system, a rocket skid, a target, and a video recording system. Using three high-speed cameras and a high-speed video recording synchronous triggering system, the system records the collision, penetration, and detonation process between the detonation system and the target, thereby achieving accurate measurement of the detonation time of the fuse.
It has achieved effective verification and measurement of the fuze delay detonation time for guided penetrating explosive projectiles in cavitation mode, which dynamically penetrates thick-scale targets, ensuring the correct detonation position and time of the warhead within the target body and improving the reliability of damage effectiveness.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of war ignition systems, specifically relating to a test system for the delayed detonation time of a target fuse for dynamic penetration strength of a penetrating explosive projectile. Background Technology
[0002] The guided penetration detonation system consists of a penetrating warhead and a penetration fuse. It is typically launched from a rocket artillery system. After flying to the target area according to a predetermined control program, the guided penetration detonation warhead collides with the target. The penetrating warhead then penetrates the target body, and the penetration fuse detonates the warhead after a delay according to its pre-set operating mode, causing damage to the target.
[0003] The detonation system of a certain type of guided penetration explosive projectile employs a multi-mode adaptive setting. Depending on the target type, the detonation system's setting modes can be divided into cavity mode, layer-counting mode, and fixed-delay mode for other typical targets. Cavity mode is primarily used to strike targets with thick-scale high-strength protective armor, while layer-counting mode is mainly used to strike targets within specific floors of high-rise buildings. Other typical targets include fortifications, aircraft shelters, underground bunkers, bridges, airport runways, and railways. Taking striking a high-strength target as an example, the guided penetration explosive projectile is set to cavity mode by the ground-based rocket artillery fire control system. After launch, the fuze completes its release according to the operational sequence. Upon contact with the high-strength target, the collision overload triggers the fuze's timing to zero. The guided penetration explosive projectile penetrates the high-strength target, and the fuze's timing reaches zero. Then, unloading is determined based on the unloading threshold. After the unloading determination is valid, detonation occurs at the delay time corresponding to the basic timetable of the cavity mode, achieving detonation within a specific distance after penetrating the entire high-strength target, thus achieving the highly efficient destructive power of cavity mode.
[0004] The delayed detonation time of the fuze in a guided penetration-propellant warhead system determines whether the rocket can penetrate to the predetermined target location before detonating, maximizing the warhead's explosive power and achieving high-efficiency damage. Taking cavity mode as an example, when penetrating a thick-scale target, the delayed detonation time of the fuze directly affects whether the warhead has reliably penetrated the target by the time of detonation, with the explosion center at the predetermined location behind the target. Direct flight verification is costly, and testing methods are limited during flight verification. Without ground verification of the delayed detonation time of the fuze on a dynamic penetration-strength target, flight tests may result in an unreasonable determination of the delayed detonation time, potentially causing the warhead to detonate prematurely inside the target or beyond a certain distance behind the target, failing to achieve the warhead's optimal destructive power.
