Protecting facilities in a new era of aerial threats

An integrated engineering system of passive protection against drones: design, manufacturing, installation.

50 kg and 200+ km/hDrone warhead weight and speed the system withstands
up to 120 mSpan with no intermediate supports and no load on process facilities

Why an ordinary net does not stop drones

  • Membrane effectA net on posts acts as a flexible membrane and deflects far inwards on impact.
  • No rigiditySuch structures are not designed for heavy aircraft over 200 kg flying faster than 150 km/h.
  • Progressive collapseDamage to a single element can bring down the entire structure.
  • Too close to the assetA net leaves no gap between the drone and the asset's shell, exposing it to a direct hit.

A protective system must not only stop the threat but also stay stable after the impact.

A drone caught in a net above a tank farm

Engineering solution: PSPK

PSPK is a spatial cross-rod structure for protective enclosures over industrial, energy and infrastructure facilities.

  • The spatial layout forms a protective envelope and redistributes impact loads
  • Safe installation with no welding on site
  • Local replacement of damaged elements
  • Adapts to complex site geometry
  • Strictly modular design
  • High survivability of the whole system

02Stress analysis

03Two-way damping

The joint elastically reflects the impact and absorbs the drone's kinetic energy, keeping it from spreading through the system.

ResultA joint with a confirmed safety margin, designed for real impulse loads.

One system, three levels of interception

Each level absorbs more of the threat's energy before it reaches the asset.

1
Cable net. First-line interception of fixed-wing drones weighing up to 200 kg and more at speeds up to 200 km/h.
2
Fine-mesh net. Catches remaining engine units, heavy parts and fuselage debris.
3
Composite layer. Reduces the impact of small fragments. Materials: Kevlar, fibreglass, carbon fibre.

Compliance with passive protection requirements

We design and build protective enclosures in line with the requirements of the Russian Ministry of Industry and Trade and applicable regulations.

  • Calculation of protection parameters

    Structural parameters, design loads and distance to the protected asset

  • Multi-level protection

    Mesh and cable solutions on a steel frame for critical elements

  • Safety and reliability

    Accounting for mechanical and fire safety, wind and snow loads

  • Serviceability

    Access openings and replacement of damaged sections without dismantling the system

≥ 4.5 mThe outer envelope is set at a safe distance from the asset, so a directed blast is absorbed in the gap.

We will design protection for your facility

Send us drawings or basic parameters of the facility. We will prepare a preliminary engineering study and calculate a cost-effective solution. At the first stage we will determine:

  • configuration of the protective system
  • approximate spans and dimensions
  • how the structure is positioned
  • required level of protection
  • further scope of design work

Multimodallogistics

We combine different modes of transport into a single supply chain, choosing road, rail, sea and air routes to cut lead times and costs.

  • 1
    Transparent costing before shipment

    We agree the route, timing and cost before the cargo is shipped.

  • 2
    Control of transshipment and connections

    We track transshipment and changes of transport, reducing the risk of damage, downtime and loss of cargo.

  • 3
    Single window

    We manage transport from the first pick-up to final delivery and take care of related services.

  • 4
    A route built for the task, not a template

    We build logistics around the client's priority: lowest cost, shortest time or an exact delivery date.
