Engineering protection for a safer tomorrow.

A passive physical shield designed to intercept drones at a distance from the asset. Flexible ring-net absorbs the strike inside its own stand-off space, away from the hangar, tank farm or substation behind it.

The threat

Drones are no longer a future risk.

They are a present one.

Modern UAVs bring more range, accuracy and payload,

and they are easy to get.

A single successful strike on a fuel store, a substation or an aircraft

can have major operational, economic and environmental consequences.

What is in the air

  • Small commercial

  • Tactical multirotor

  • Fixed‑wing / one‑way

  • Larger / higher‑energy

Illustrative drone classes, not to scale. The design basis is agreed per site.

Three approach vectors.

Lateral, Oblique, Overhead. Fly each one at the envelope, then at a fence.

Choose an approach path to fly a drone in.

Aviation Concept visualisation

The envelope stands clear of the hangar. Doors and tow path stay open.

Built around the asset. Not onto it.

Ground fencing protects a boundary. The envelope protects the whole volume: sides, oblique angles and roof. The frame stands on its own foundations and stays structurally independent of the building.

Choose a layer to isolate it in the drawing.

Controlled deformation is the mechanism. Not rigid resistance.

The net is designed to move so the asset does not. A strike is managed in six stages.

    Intercept

    The drone meets the ring-net at a distance from the asset.

  2. 02S1

    Deform

    Rings stretch and the panel bows into its stand-off space.

  3. 03S1

    Distribute

    Force spreads across the net instead of one point.

  4. 04LT

    Dissipate

    Brake elements on the ropes absorb the remaining energy.

  5. 05LT

    Transfer

    Loads run through ropes and poles into the foundations.

  6. 06T2

    Retain

    T2 mesh is designed to hold debris and fragments above the protected roof.

Passive anti-drone protection

No detection.No electronics.No power.Always on.

Nothing to spoof

Nothing to jam

Nothing to switch off

Day, night, every season

It works alongside active counter-UAS systems. It does not replace them. When a drone gets through, the net is the last layer between it and the asset.

Reference tests of the barrier.

Full-scale impact tests from the barrier supplier, run with a test mass rather than a drone. They show how the flexible ring-net deforms, absorbs and holds; they are not qualification of a ZG Solutions anti-drone assembly.

Reference test basis: 1,000 kg · 25 m/s · 312.5 kJ

  • Lateral impact, test mass

    The side panel deforms and arrests the mass

  • Vertical drop into the net

    The net bows and holds

  • Net after impact

    Rings hold around the strike point

No universal barrier. Every site is engineered.

Mass and speed set the impact energy. Approach angle, airframe, payload and site constraints set the geometry. Final stand-off and loop count follow the threat basis agreed with the client.

Ek = ½ m v²

The supplied flexible-barrier material states a kinetic design range of about 50–400 kJ. The 312.5 kJ test is a reference for barrier behaviour, not a claim about any drone or a project design threat.

Impact energy

Matches the manufacturer-declared reference test: a 1,000 kg test mass at 25 m/s. A test mass, not a drone.

It has to survive the climate long before it meets a drone.

Site exposure

  • Marine and salt-laden air

    Corrosion protection rated for the site's exposure category, with an optional duplex marine coating.

  • Heat, sun and UV

    Materials and coatings chosen for high temperatures and years of solar exposure.

  • Wind, sand and dust

    Structure, nets and fittings sized for site wind and abrasion.
