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

هڪ 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, ڪنڊ اکيون, 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. اي 6 mm braided aramid rope breaks at 2.6 t and is the panel for perimeter work, prisons, schools and anywhere the aperture has to be fine without the panel becoming heavy. اي 10 mm braided aramid rope breaks at 7 t and is the panel for real kinetic impact — refineries, substations, بندرگاهن, 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, ۽ انهن مان صرف هڪ رسي آهي.

• 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.
• سرحد. 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.
• اينڪرز. 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 صفحو; this page carries the specification and the fittings you need to place an order.

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.

سرحد, 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.

ٽيبل 3 — Stainless steel wire rope mesh, aluminium double ferrule to DIN EN 13411-3, SUS 304 / 304ايل / 316 / 316ايل. 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 جي طرف 1/6 of the breaking force.

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

ٽيبل 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 ايم ايم, 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, ڳري ملبي ۽ ڦاٽڻ, and we make wire rope assemblies on the same presses — see تار رسي slings. It is not the right answer for a fast, هلڪو جهاز, because the ferrule sets the limit at about a tonne.

Choosing rope and mesh

Two decisions, هن ترتيب ۾: what has to be stopped, then what has to be seen through.

Installation and stand-off

• بيهڻ. Keep at least 1 مان پينل جي پويان صاف. A caught aircraft has to deform into space, not into the asset.
• لنگر جي فاصلي. 2 m يا سرحد جي ويجهو. The border spans between anchors and carries everything the panel collects.
• ٽينشن. Take the slack out and stop. هڪ knotted aramid پينل ان جي پهرين لوڊ هيٺ سيٽ; over-tensioning creeps the knots and works the anchors loose.
• ڇت جي واپسي. A vertical wall can be flown over. Anything above about 6 m کي واپسي يا مٿين پردي جي ضرورت آهي.
• No cut mesh. Never cut an aperture for access or a service. Put a reinforced opening on the drawing.
• واءُ. اي 100 mm net لڳ ڀڳ آهي 30 % مضبوط; مقامي بنيادي ونڊ پريشر تي پينل کي ٻرندڙ سطح جي طور تي ڳڻيو, and size the posts to that, not to the drone.

نشان لڳائڻ, packing and documents

Each panel is rolled, strapped and tagged, with the tag carrying panel size, رسي جو قطر, ميش, فائبر ۽ بيچ نمبر. 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?

اي 6 mm aramid rope breaks at 2.6 t ۽ a 10 mm تي 7 t. The largest standard ferrule on steel wire mesh — 4.0 mm rope — breaks at 981 kgf, بابت 0.98 t. 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, رسي جي مرڪزن جي وچ ۾ ماپي ويندي جيستائين واضح افتتاح بيان نه ڪيو وڃي.

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. اي 5 kg munition arriving at 100 m/s is arrested with about 62.5 kN if it is stopped over 0.4 م; 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. هڪ خراب سرحد رسي, a pulled corner eye or a large damaged area is replaced rather than patched.

Does the net need power or detection?

نه. 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.
