NMX-HFTF-40 · ENGINEERED TO ORDER — FIRE SIMULATION & VALIDATION FACILITY

Set the fire on purpose. Then prove the system that fights it.

Name: Hangar Fire Test Facility — Large-Scale Fire Simulation & Validation Facility
Brand: Neometrix

A large-scale fire simulation facility built around a 40 × 15 × 10 m steel test chamber — roughly 6,000 m³ of enclosed volume in which real, metered, fully instrumented fires are raised so that hangar fire-fighting systems can be validated and performance-evaluated before anyone relies on them. Dual-fuel ignition, flame imaging, high-capacity extraction and PLC/SCADA control. Engineered to order — the reference design on this page has not yet been built.

Overview

A fire-fighting system is a promise. This is where it gets tested.

A hangar holds an enormous amount of value in one undivided volume, and the system meant to protect it usually gets proven by calculation, a datasheet and a discharge test into open air. None of that tells you how the system behaves against a real fire, in a real enclosure, at real scale — how fast it detects, how the suppressant actually reaches the seat of the fire, and whether it holds. The only way to know is to raise the fire and watch.

Fig · 02 The fuel metering and ignition skid — illustrative render

The facility exists to make that fire repeatable. Fuel is delivered to the trays and spray nozzles through a metered dual-fuel train — light diesel oil and LPG — with in-line turbine flow measurement, pressure transmitters and remotely operated valves, so a given fire scenario can be set, recorded and then set again identically for the next system under test. A fire you cannot reproduce is an anecdote, not a test.

Around it sits everything needed to run that fire safely and learn from it: a steel chamber sized to behave like a hangar bay, simulation mock-ups representing the protected asset, flame imaging through toughened viewing windows, pressure, flow and temperature instrumentation, high-capacity extraction to clear the products of combustion, and a PLC/SCADA system that sequences the test and logs every instrumented channel from a control room behind the glass.

Fire in a large enclosure does not behave the way a calculation says it will. Scale is not a detail here — it is the whole point of the building.

Engineered to Order

Designed against a research specification

This facility was engineered to the requirements of an Indian government fire-safety research laboratory and passed technical evaluation against that specification — design, structural basis and sub-system scope assessed by the procuring establishment’s technical evaluators. A technical evaluation is not an approval, certification or endorsement.

Full Scale · 40 × 15 × 10 m

Big enough to behave like a hangar bay

Sub-scale rigs can be Froude-scaled for plume geometry, but radiative feedback does not scale with them — and at this size radiation is what drives the fire. That is the effect a suppression system has to overcome, and the only way to see it is at scale.

Scope · Foundation to Commissioning

One party, foundation to first fire

When you order one, scope runs from structural design and the reinforced-concrete platform through fabrication and erection of the chamber, the fuel, ventilation, lighting and instrumentation systems, to commissioning and an evaluation campaign with on-site support.

Architecture

Ignite, contain, measure.

The schematic below is the whole facility — the metered fuel and ignition train, the chamber with its mock-ups, trays and the system under evaluation, ventilation, imaging and instrumentation, and the control chamber that runs it.

Fig · 03 The whole facility — metered dual-fuel ignition into the simulation chamber, the fire-fighting system under evaluation, flame imaging and instrumentation, and PLC/SCADA control

Arc · 01

The Simulation Chamber

A cuboidal steel enclosure of 40 × 15 × 10 m — mild-steel panelled walls and ceiling on a rolled-channel support structure, with an inclined roof and a high-temperature fire-resistant coating inside and out. It stands on a reinforced-concrete platform laid out for drainage with covered channels, because everything discharged into a fire test has to come back out. Sub-floor pop-up nozzles, low- and high-pressure, are cast into the same slab where a system under evaluation discharges from floor level.

Arc · 02

Fuel, Ignition & Trays

A dual-fuel train delivers LDO and LPG on separate metered legs — liquid fuel to spray nozzles and steel trays through an in-line turbine meter and totaliser, gas to its burners on its own metering — with pressure transmitters, glycerine-filled gauges and needle, ball and solenoid valves, all stainless-wetted and rated for the service temperature. The point is control — a scenario that can be dialled in, held, logged and repeated. Because a gas fire is being raised inside a large enclosure, the fuel train is interlocked to LEL gas detection with double-block-and-bleed isolation and a forced purge before any re-light.

Arc · 03

Ventilation & Containment

Centrifugal blowers extract the products of combustion, with fresh-air supply deliberately set below extract so the chamber holds a slight negative pressure and smoke does not escape past the door seals. It is a purge system, not a smoke-control system: its job is to clear the chamber for entry within minutes of a run. Blowers are housed to keep noise down; cabling is fire-resistant with circuit integrity under fire; the facility carries lightning protection and dedicated instrument earthing.

Arc · 04

Imaging, Instruments & Control

Flame imaging records how the fire grows and how it responds to discharge, through toughened viewing windows, with the chamber lit by protected high-output luminaires. Pressure, flow and temperature channels are logged in parallel. A PLC/SCADA system in an insulated, climate-controlled control chamber sequences the run, holds the interlocks and captures the record, with a separate assembly and data-analysis chamber alongside.

Specifications

Reference configuration, scaled to your scenario.

The parameters below describe a reference full-scale configuration. Chamber size, fire load, fuel train, ventilation capacity and instrumentation are all set by the fire scenarios you need to reproduce and the protected volume you are qualifying a system for.

Why it is run from behind glass

Every part of the test that can be done remotely is done remotely. Fuel admission, ignition, ventilation and the suppression trigger are sequenced by the control system, so the operator sets up the scenario and then watches it through toughened glass rather than standing in the enclosure.

That is a safety decision first, but it is also what makes the data worth having. A test run to a programmed sequence, with every channel logged against a common time base, can be compared against the next one. A test run by hand cannot.

Variants

One discipline, many volumes to protect.

Different tenders call this a fire test facility, a fire simulation chamber, a burn hall or a suppression validation rig. The discipline is the same — raise a controlled fire, contain it, measure everything. The scale is set by the volume you are protecting.

Var · 01

The Full-Scale Facility

The reference 40 × 15 × 10 m configuration on this page, with dual-fuel ignition, imaging, extraction and SCADA — sized for hangar and large-enclosure suppression validation.

Var · 02

Other Enclosure Scales

Smaller burn halls and compartment rigs where the protected volume is a machinery space, a store or a compartment rather than a hangar bay — the fuel train, extraction and instrumentation scale down with the enclosure.

Var · 03

Fuel & Scenario Sets

Liquid pool fires, gas-fed fires, running-fuel and spray fires, or combinations — the metering train and tray layout are configured to the scenarios a given standard or acceptance regime calls for.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 Why does a fire test chamber need to be this big?

Because fire does not scale linearly. In a large enclosure a fire develops a tall buoyant plume, forms a hot smoke layer under the ceiling, and starts radiating heat back down onto the fuel and the surrounding structure — which accelerates it. Those effects are what a hangar suppression system actually has to fight. They do appear in a small rig — but radiative feedback does not scale with the rig, so it is systematically under-represented. A 40 × 15 × 10 m enclosure gives roughly 6,000 m³ and about 10 m of height, which is far closer to a real hangar bay than any bench rig, though a full hangar is taller again.

Q · 02 Why two fuels — LDO and LPG?

They do different jobs. A liquid fuel like light diesel oil in a tray gives you a sustained pool fire with a realistic soot-laden, radiating flame — close to what an actual hydrocarbon spill fire looks like, and the harder target for a suppression system. Gas gives you a clean, fast, precisely controllable flame that can be started and stopped instantly, which makes it ideal for ignition and for scenarios where repeatability matters more than realism. Each fuel runs on its own metered leg — a liquid turbine meter on the LDO train, separate gas metering on the LPG — so one facility covers the range from a controlled ignition source to a fully developed pool fire.

Q · 03 How is a test made repeatable?

By metering the fuel rather than just supplying it. Flow is measured in line with a turbine meter and totaliser, pressure is transmitted from the fuel train, and the valves are remotely operated on a programmed sequence, so a scenario is defined by numbers rather than by judgement — this fuel, this flow, this duration, this tray layout, this ventilation state. Because the fuel is metered and totalised, each run also carries a nominal heat release rate — flow times calorific value — so scenarios are specified in kW rather than in tray counts, and two suppression systems tested months apart can be compared honestly.

Q · 04 What happens to the smoke and the run-off?

Both are designed for from the start. High-capacity centrifugal blowers extract the products of combustion, with fresh-air supply deliberately set below extract so the chamber sits slightly negative and smoke stays inside it. It is a purge system rather than a smoke-control one — at this capacity its job is to clear the chamber for entry within minutes of a run, not to hold a layer down during one. On the floor side, the chamber sits on a reinforced-concrete platform with a drainage layout and covered channels running to an interception sump, because a suppression test discharges a large volume of water or foam carrying unburnt fuel and soot. Fuel residues are separated before anything is discharged, and where the agent under test is a fluorinated foam the run-off is contained rather than connected.

Q · 05 Has this facility been built?

Not yet — and it is worth being straightforward about that. The design on this page was engineered to an Indian government fire-safety research laboratory’s specification, but no order followed, so we make no claim to a commissioned facility or an operating reference. What exists is the full engineering: structural basis, chamber design, fuel and ignition train, ventilation, instrumentation and control scope. We would build it to your specification on the same basis.

Q · 06 Can you scope one to our scenarios?

Yes — that is how these are built. Send the protected volume you are qualifying a system for, the fire scenarios and fuels you need to reproduce, the suppression systems to be evaluated, the instrumentation and imaging you want logged, and the site and services available. Chamber size, structure and foundation, fuel train, ventilation capacity, imaging, instrumentation and the control system are then scoped against that and settled at design review. A compliance matrix returns within two working days.
