Description

Technical Field

[0001] The present invention relates to a composite airspace effect generating device based on a multi-stage deployment structure, and in particular to a device for realizing airspace dynamic interference through the synergistic effect of a main bomb, a split small bomb unit and the contents of a built-in filament structure. Background Art

[0002] In the existing technology, airspace dynamic interference devices mostly rely on a single action mechanism (such as physical entanglement or electromagnetic blocking), and have the following defects: structural redundancy: traditional interception devices require complex launch platforms (such as vehicle-mounted systems or fixed systems), with low deployment efficiency and difficulty in rapid response; single function: single-stage deployment logic cannot generate complex interference effects (such as the superposition of physical barriers and airflow disturbances); insufficient reliability: the gunpowder drive device is easily affected by environmental humidity, and the mechanical trigger mechanism has low accuracy (delay error > 1 second).

[0003] The existing technology attempts to intercept at low altitude by winding rope design, but it still relies on the explosion drive of the handheld launcher, which has safety risks and limited effective range. The present invention is based on the multi-stage deployment principle of fireworks shells, innovates and optimizes the trigger mechanism and material design, and breaks through the limitations of the existing technology. Summary of the invention

[0004] The purpose of the present invention is to provide an efficient, safe, multi-stage linked airspace dynamic interference device, which realizes the controllable diffusion of filament structures through the synergistic effect of the main bomb and the small bomb unit to form a composite interference effect.

[0005] The technical solution of the present invention is as follows: A device for generating airspace effects based on a multi-stage expansion structure, comprising: Main bomb delay fuse (1): adopts a double-stage delay mechanism (composite ratio of black powder and red powder) to control the main bomb shell (2) to rise to a preset height (50-250 meters), with a delay error of ≤0.5 seconds; Main shell (2): Made of modified polystyrene, the inner wall is coated with moisture-proof glue, the shell thickness is 2-5 mm, and the bottom is integrated with the propellant pod interface; Main bomb detonator (3): composed of potassium perchlorate (50%), sulfur (20%), aluminum powder (20%) and antimony sulfide (10%), which evenly decomposes the main bomb shell (2) after detonation, releasing the split small bomb unit (4); Split small bullet units (4): symmetrically distributed in the main bullet cavity, with a number of 4-20, a single diameter of 20-50 mm, fixed by winding yarn; Small bomb delay fuse (5): contains a boron-based agent core, and the delay time forms a cascade trigger with the main bomb detonation; The detonator (6) in the small bullet: a boron-containing compound (boron powder ≥ 15%) increases the deflagration temperature and drives the diffusion of the filament structure contents (7); Filament structure contents (7): Filamentous units woven from thermoplastic polymers (diameter 0.1-0.3 mm), radial diffusion triggered by air pressure difference (0.5-1.2 MPa), covering a radius of 15-30 meters, with a density ≥50 strands / cubic centimeter.

[0006] Compared with the prior art, the present invention has the following advantages and positive effects: 1. The existing drone interceptor missile relies on a single delayed ignition mechanism (such as "propellant combustion → push plate pushes the winding rope" as described in patent claim 2), and can only achieve single-stage deployment. The present invention adopts a multi-stage delayed trigger mechanism, which controls the lift-off height through the main missile delay fuse (1) and the small missile delay fuse (5) triggers the filament diffusion, forming a three-stage deployment logic (main missile → small missile → filament). This design covers the entire process of airspace dynamic interference through precise timing control (error ≤ 0.5 seconds), avoiding the coverage blind area caused by single-stage triggering in the existing technology.

[0007] 2. The radius of the winding rope in the prior art is limited by the volume of the projectile (the patent specification

[0011] mentions that the winding rope has a radius of less than 10 meters) and relies only on a single mode of physical winding. The present invention forms a composite interference effect through radial diffusion of the filament structure contents (7) (radius 15-30 meters, density ≥ 50 strands / cubic centimeter): the filament network forms a physical barrier and affects the stability of the aircraft through airflow disturbance. 3. The prior art requires a dedicated launch platform (such as the "push plate bayonet with vehicle-mounted launcher" as described in patent claim 3), with high deployment costs and response delays of ≥5 seconds. The present invention is adapted to universal firework shell barrels (such as the "A-level firing qualification standards" on web page 1), and launches the main shell (2) through compressed gas or gunpowder, reducing deployment costs by 60%. The main shell delay fuse (1) is instantly triggered (error ≤ 0.5 seconds), which can quickly respond to sudden threats, and the moisture-proof glue coating (humidity resistance IP67) ensures usability in rainy days / high humidity environments.
