Aramid Anti-Drone Nets | 2.6 ט & 7 t Knotted Panels

א aramid anti-drone net is a knotted rope panel hung across the line a small unmanned aircraft would fly through. We supply it as a complete assembly rather than a loose piece of netting: knotted aramid panel, spliced border, עיניים בפינה, tensioners and anchors, quoted per opening so that the panel, the border and the fixings carry the same load.

Two rope sizes cover almost every installation. א 6 mm braided aramid rope breaks at 2.6 ט and is the panel for perimeter work, prisons, schools and anywhere the aperture has to be fine without the panel becoming heavy. א 10 mm braided aramid rope breaks at 7 ט and is the panel for real kinetic impact — refineries, substations, נמלים, airfields. Both are knotted, both are spliced into the border, and both are supplied with the fittings that take the load out of the mesh and into the structure.

What the assembly is made of

Four elements decide whether the barrier works, ורק אחד מהם הוא החבל.

• The panel. A 12-strand braided aramid rope, double-knotted into square or diamond mesh. The knot gathers four rope ends, so the load entering from one direction leaves through the other three instead of passing through a clamp.
• הגבול. The same braid or one size up, double-laid and spliced — never knotted — around the perimeter. The border collects everything the mesh gathers and hands it to the corner eyes.
• The corner eyes and fixing points. Spliced eyes with stainless thimbles at the corners, eyelets or D-rings along the edge at your anchor spacing.
• העוגנים. Posts, wall plates or stand-off brackets. A panel that is strong enough and tied to a post that is not will fail at the post.

The construction detail behind the knot, the braid and the fire behaviour is set out on the high strength anti-drone rope net עַמוּד; this page carries the specification and the fittings you need to place an order.

פרמטרים טכניים

The figures below are the manufacturing range. The batch certificate supplied with the panel governs, and the installed barrier is only as strong as its border and anchors.

גְבוּל, fittings and anchor schedule

Buyers rarely fail on the panel and often fail on what it is tied to. The schedule below is what we supply with a standard opening; every line is confirmed on the approval drawing before the panel is woven.

Aramid against steel wire mesh

Steel wire mesh is the barrier most buyers compare against, and the comparison is usually made on the wire. It should be made on the joint. A clamped stainless mesh is pressed together with aluminium double ferrules, one at every crossing, and the ferrule — not the wire — sets the limit of the panel.

The following is the specification the steel mesh trade works to, translated from the Chinese original supplied with the material.

לוּחַ 3 — Stainless steel wire rope mesh, aluminium double ferrule to DIN EN 13411-3, SUS 304 / 304ל / 316 / 316ל. Ferrule joints must not be bent again or re-used after pressing; for dynamic, impact or personnel duty the working load is taken as 1/5 אֶל 1/6 of the breaking force.

Put the two tables side by side and the difference is not marginal.

לוּחַ 4 — Like for like: one element of net against one element of net.

Even the lightest rope we put in an anti-drone panel — 6 מ"מ, 2.6 t — carries 2.7 times the load of the heaviest ferrule in the steel table, and it does so at roughly a tenth of the weight per square metre. The gap matters for a second reason: a steel mesh repeats its weakest joint hundreds of times across an opening, so a drone finds the nearest one, while a knotted panel spreads the impact through neighbouring meshes and degrades instead of unzipping.

Steel mesh is still the right answer for rigid screens, פסולת כבדה ושחיקה, and we make wire rope assemblies on the same presses — see מתלים של חבל תיל. It is not the right answer for a fast, מטוס קל, because the ferrule sets the limit at about a tonne.

Choosing rope and mesh

Two decisions, לפי הסדר הזה: what has to be stopped, then what has to be seen through.

Installation and stand-off

• תֵיקוּ. Keep at least 1 מ' ברור מאחורי הפאנל. A caught aircraft has to deform into space, not into the asset.
• מרווח עוגן. 2 מ' או קרוב יותר לאורך הגבול. The border spans between anchors and carries everything the panel collects.
• מֶתַח. Take the slack out and stop. לוח ארמיד מסוקס מתקבע תחת העומס הראשון שלו; over-tensioning creeps the knots and works the anchors loose.
• החזרת גג. A vertical wall can be flown over. Anything above about 6 m צריך החזרה או וילון עליון.
• No cut mesh. Never cut an aperture for access or a service. Put a reinforced opening on the drawing.
• רוּחַ. א 100 מ"מ נטו הוא בערך 30 % מוּצָק; חשב את הפאנל כמשטח נקבובי בלחץ הרוח הבסיסי המקומי, and size the posts to that, not to the drone.

צִיוּן, packing and documents

Each panel is rolled, strapped and tagged, with the tag carrying panel size, קוטר חבל, רֶשֶׁת, סיבים ומספר אצווה. Panels travel in a PVC bag inside a woven outer, or on a pallet for multi-panel orders. Batch test records, a packing list and a declaration of conformity are supplied with the shipment; state the standard your site or customs authority needs and the documents are prepared to it.

Questions buyers ask

How strong is an aramid anti-drone net against a steel wire mesh?

א 6 mm aramid rope breaks at 2.6 t ו-a 10 מ"מ בשעה 7 ט. The largest standard ferrule on steel wire mesh — 4.0 mm rope — breaks at 981 kgf, אוֹדוֹת 0.98 ט. On joint strength the 10 mm aramid element carries about seven times the best steel mesh joint, and even the 6 mm element carries 2.7 times as much.

What mesh size do I specify?

40–60 mm for small multirotors, so a propeller blade cannot pass; 80–100 mm for larger multirotors and fixed-wing airframes; 120 mm where panel weight and wind area matter more than aperture. The rule is that the aperture must be smaller than the part that would arrive first, נמדד בין מרכזי חבל אלא אם צוין פתח ברור.

Is it a panel or a complete assembly?

A complete assembly: knotted panel, spliced border, corner eyes with stainless thimbles, edge eyelets where specified, tensioners and anchors, tagged and documented. Panels can be supplied loose where you already have the anchors and only need the net.

Will it stop a drone carrying a munition?

The net stops the delivery, not the warhead, and that is the whole point of netting a position. א 5 kg munition arriving at 100 m/s is arrested with about 62.5 kN if it is stopped over 0.4 מ; shared across the four ropes of an engaged mesh that is roughly 16 kN per rope, against about 34 kN carried by a knotted 10 mm element even at 50 % knot efficiency. Break the delivery and the warhead never arrives.

Can a damaged panel be repaired on site?

Yes on knotted construction. One damaged mesh is re-knotted with the same braid and the repair is recorded. חבל גבול פגום, a pulled corner eye or a large damaged area is replaced rather than patched.

Does the net need power or detection?

לֹא. It is a passive physical barrier: no power, no radar, no operator. That is also why it still works against fibre-optic and pre-programmed drones that electronic countermeasures cannot reach.
