Description

Technical Field

[0001] This invention relates to a fiber bundle filament pack loaded in an aircraft payload, and particularly to a series-structured fiber bundle filament pack capable of unfolding long fiber bundles for soft damage to electric targets or low-speed, small unmanned aerial vehicles, belonging to the field of soft damage element technology. Background Technology

[0002] After the conductive fiber bundle (hereinafter referred to as "conductive filament bundle"), which is made of fiber bundles, is released by the payload of the aircraft, the fiber bundle (hereinafter referred to as "filament bundle") unfolds from the conductive filament bundle under the action of gravity, wind force and aerodynamic force, forming a filament bundle tens of meters long. It can be attached to the high voltage power grid line (hereinafter referred to as "power grid target") to produce a short circuit effect, that is, soft damage to the power grid target. For high voltage overhead line targets in mountainous areas, the distance between the power line and the ground is large. If the filament bundle can produce a phase-to-ground short circuit mode, an ultra-long filament bundle is required. However, due to the limitations of the internal structure of the payload cavity, the unfolded filament bundle of a single conductive filament bundle is 10m to 45m (generally 30m), while in reality, a conductive filament bundle of hundreds of meters long is required to achieve the phase-to-ground short circuit mode from the high voltage line to the valley depression. Similarly, fiber bundles composed of high-strength, non-conductive fiber bundles can unfold in the air to form a mesh-like fiber curtain, softly intercepting low-altitude, slow-moving, and small UAV targets. The fiber bundles can entangle the UAV's propellers, causing them to stop rotating. UAVs that lose power or experience asymmetrical power will crash and lose their ability to complete their intended combat missions. High-power fiber curtains are characterized by large-area interception screens composed of numerous fiber bundles hundreds of meters long. Therefore, to increase the soft-kill capability of aircraft payloads, there is a demand for fiber bundles with serially connected structures that can unfold into long or ultra-long fiber bundles. Summary of the Invention

[0003] The technical problem solved by this invention, a series-structured fiber bundle, is the severe deficiency in the unfolded fiber bundle length of existing standard or shelf-mounted fiber bundle products. It provides a series-structured fiber bundle (hereinafter referred to as: strip-shaped fiber bundle); it consists of two or more sub-fiber bundles strung together to form a strip-shaped fiber bundle, which is then loaded into a payload. The filament shafts on each sub-fiber bundle are designed with an axially strung structure, allowing several or a dozen sub-fiber bundles to be longitudinally connected to form strip-shaped fiber bundles of different lengths. The ends of the fiber bundles on each sub-fiber bundle are connected, and the fiber bundles unfold sequentially in the air. The filament shafts of the middle sub-fiber bundles are discarded after unfolding without affecting the fiber bundle connection, ultimately forming a fiber bundle of a predetermined length (hundreds of meters to several hundred meters) in the air. Multiple strip-shaped fiber bundles are loaded into the payload, and when unfolded, they form a fiber bundle curtain. The combined action of multiple payloads can form a large-area fiber bundle curtain, thereby powerfully soft-damaging the target.

[0004] In order to solve the above technical problems, a series structure fiber bundle filament bundle of the present application mainly comprises a plurality of sub filament bundles (the sub filament bundle can refer to "a conductive fiber filament bundle suitable for severe flight environment, ZL201921982552.1) and a small umbrella; the sub filament bundle is composed of a fiber bundle (a conductive or non-conductive fiber bundle), a filament shaft and a plurality of blades; the filament shaft is composed of an axle tube and an axle protrusion, which plays a role in longitudinal stringing. The head of the first sub filament bundle fiber bundle is connected with the small umbrella, the tail of the fiber bundle is connected with the head of the next sub filament bundle fiber bundle, a plurality of sub filament bundles are slidably inserted into the axle tube of the next filament bundle through the axle protrusion, and are longitudinally strung into a series structure fiber bundle filament bundle.

[0005] The above-mentioned conductive or non-conductive fiber bundle is tens of meters long, is wound on the filament shaft, and is composed of a plurality of blades and other auxiliary components to form a single sub filament bundle. The series structure fiber bundle filament bundle is achieved by sliding connection of the axle protrusion and the adjacent axle tube; the series structure fiber bundle filament bundle is suitable for filling in the payload of the aircraft, and a plurality of series structure fiber bundle filament bundles are arranged in parallel and are independent of each other.

[0006] The series structure fiber bundle filament bundle of the present application is filled in the payload of the aircraft, and the working process comprises the following steps:

[0007] (1) The series structure filament bundle composed of two or more sub filament bundles is arranged in parallel and filled in the payload, the top end sub filament bundle fiber bundle is connected with the small umbrella, and the small umbrella is in a folded state;

[0008] (2) The series structure filament bundle is thrown out in the upper space of the target from the payload, the small umbrella is unfolded to generate lift under the action of aerodynamic force, and each sub filament bundle starts to separate from each other under the action of aerodynamic force and gravity, but the heads and tails of the fiber bundles of each sub filament bundle are connected with each other;

[0009] (3) The fiber bundles on the sub filament bundles are unfolded under the combined action of the buoyancy of the small umbrella and the aerodynamic force and gravity, and the fiber bundles on the lowermost end sub filament bundle are unfolded the fastest, and the fiber bundles on each sub filament bundle are all unfolded to a length of tens of meters in about ten seconds;

[0010] (4) The fiber bundles of each sub filament bundle on the series structure filament bundle are connected into long fiber bundles, and are suspended and fall under the action of the lift of the small umbrella;

[0011] (5) The long state fiber bundles formed by a plurality of series structure filament bundles constitute a large display or a curtain of fiber bundles, and fall and intersect with the target with great power;

[0012] (6) The large display of conductive fiber bundles falls on the power target with high probability, and plays a high-efficiency short-circuit role;

[0013] (7) The large display of non-conductive fiber bundles interacts with the "low, slow and small" unmanned aerial vehicle target in the air, and improves the interception probability and failure probability of the target.

[0015] The series structure fiber bundle filament bundle can realize small sub-filament bundle air cooperation development into long fiber bundle, and meets the demand of small and medium-sized volume effective load on target large power soft action. BRIEF DESCRIPTION OF DRAWINGS

[0023] EMBODIMENT

[0024] Taking the fiber cluster of a certain aircraft payload as an example, 18 series structure conductive fiber clusters are vertically packed in the payload, and are parallel to each other. Each series structure fiber cluster has three sub-clusters. The diameter of the sub-cluster is less than 14 mm, and the length is 17 mm. The total length of the three sub-clusters (excluding the small umbrella) is less than 50 mm, and the total mass (including the small umbrella) is less than 8 g. The conductive fiber bundle adopts a standard continuous aluminum-plated glass fiber bundle, and the unit length mass is less than 0.04 g / m. The length of the sub-cluster conductive fiber bundle is not less than 35 m, and the total length of the three sub-cluster conductive fiber bundles is not less than 105 m.

[0025] The dynamic scattering process is as follows:

[0026] (1) The aircraft payload test piece is radially scattered at a height of about 150 m, and 8 series structure fiber clusters are scattered. At this time, the wind speed is 1.6 m / s, the radial scattering speed is about 22 m / s, the strip-shaped cluster is scattered at a distance of about 2 meters from the payload, the small umbrella is completely opened, and the three sub-clusters are separated at 3 meters.

[0027] (2) The small umbrella generates lift to drive the three sub-clusters to float and drift. The conductive fiber bundle on the three sub-clusters gradually expands. About 5 seconds, the lowermost sub-cluster expands 35 m long conductive fiber bundle. At this time, the middle sub-cluster expands about 8 m long, and the sub-cluster connected with the small umbrella expands about 4 m long. In the 8th second, the middle sub-cluster expands 35 m, and in the 11th second, the sub-cluster connected with the small umbrella expands 35 m long, and the tail end carries the silk shaft.

[0028] (3) The small umbrella carries 105 m long conductive fiber bundle and drifts. About 30 seconds, it begins to land, and 39 seconds, it all drifts to the ground. The total length of the conductive fiber bundle is 106.3 m, which meets the requirements of the predetermined structure design and performance test verification.
