Overview

It only gets used once. It has to work.

An ejection seat is the last resort — the system a pilot reaches for once, unrehearsed, in the worst seconds of their life, when everything else has already failed. There is no second attempt and no practice run. So every function is proven exhaustively on the ground, before it ever flies — and that proving happens in a test facility like this one.

You test it without a live ejection. A live ejection is violent, destructive and single-use, so the facility qualifies the seat’s sequencing, structure, restraint, parachute and life-support through ground tests, drop tests and instrumented measurement — proving the escape logic and hardware without a live shot.

The occupant is the point. A seat can survive the event and still injure the pilot, so instrumented anthropomorphic test devices — crash-test dummies — measure the head, neck and spine loads against injury criteria. The seat passes only if the occupant would come through intact.

Machine-only, life-safety. This is a test facility for aircrew survival equipment — a set of instrumented rigs that measure and qualify — in the same life-safety engineering register as our human-rated systems, not something that flies.

Everything else on the aircraft is designed so the pilot never needs this. This is the one system designed for the moment they do — so it is the one you test hardest.

Life-Safety Engineering

The human-rated register

Qualifying aircrew survival equipment is life-safety engineering with instrumentation and controls — the same discipline behind our human-rated hyperbaric systems, turned to the moment of escape.

Prove It On the Ground

Every function, without a live shot

Sequencing, drop, restraint, parachute and life-support are proven through ground and drop tests and instrumented measurement — so the escape works the first time it is ever used for real.

Honest on Sourcing

We integrate; the dummies are specialist

The anthropomorphic test devices, cameras and data-acquisition are bought-in; Neometrix engineers the facility — drop tower, static and restraint rigs, thrust stand, sequencing controls and instrumentation. No delivered facility is claimed on this page.

Architecture

Sequence, survive, measure.

The schematic shows the tests applied to a generic instrumented test article — functional, drop, restraint — and the measurement of the occupant, the parachute and the life-support, with the detail panel setting out what each test proves.

Arc · 01

Functional & Sequencing

The escape sequence — drogue, main recovery parachute, harness release and seat-occupant separation — verified for order, timing and interlocks, on the ground and without a live ejection, so the logic is proven before anything moves for real.

Arc · 02

Drop, Static & Restraint

A drop tower and static rigs qualify the seat structure and mounting to crashworthiness loads, and a restraint & harness rig pull- and cyclic-tests the harness, restraint and inertia-reel system to load.

Arc · 03

Occupant-Injury Measurement

Instrumented anthropomorphic test devices measure the head, neck and spine accelerations and forces against injury criteria — dynamic response index, head injury criterion — because the seat passes only if the occupant survives intact.

Arc · 04

Parachute, Support & Capture

The recovery parachute extraction, deployment and inflation, and the emergency oxygen and survival-pack functions — with high-speed cameras and multi-channel data acquisition capturing every test and the catapult thrust measured on an instrumented stand.

Where escape testing goes wrong

In the measurement and the sequence, not the drama. A test that watches the seat fly but does not instrument the occupant proves nothing about whether a pilot would survive it; a sequencing check that misses a few milliseconds of timing lets a parachute deploy a beat too late; a camera set too slow or a data channel too coarse loses the very event — measured in milliseconds — that the test exists to capture.

That is why the occupant is fully instrumented to injury criteria, the sequence is timed and interlocked, and the capture is high-speed and multi-channel. An escape test is only worth the fidelity of what it measures about the human being it exists to save.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 Is this machine-only and life-safety? What exactly does the facility do?

No — it is the opposite. An ejection seat is aircrew life-safety equipment: its entire purpose is to save a pilot’s life when an aircraft is lost, and this is a test facility that qualifies that survival equipment on the ground. It is machine-only — a set of instrumented rigs that verify the seat’s escape sequencing, its structure and restraint under crashworthiness loads, the loads a pilot’s body would experience, and the recovery parachute and life-support functions. Everything on this page is machine-and-measurement. In the same way a car crash-test lab exists to make cars safer for people, this facility exists to make aircrew escape safer and to prove, before anyone’s life depends on it, that the system works. We build it in the same life-safety engineering register as our human-rated hyperbaric systems, and the article under test on this page is described generically, without reference to any specific seat model or aircraft.

Q · 02 Why test on the ground instead of just ejecting a live seat?

Because a live ejection is violent, destructive, expensive and single-use — and it tells you far less than a properly instrumented ground programme. When you actually eject a live seat you get one data point and a wrecked seat, with limited ability to see why anything happened. A ground facility instead breaks the escape into its parts and proves each one, repeatedly and measurably: the sequencing and timing are verified without a live shot; the structure and restraint are qualified on a drop tower and static rigs to defined crashworthiness loads; the occupant loads are measured with instrumented dummies; the parachute deployment and the life-support are function-tested; and the catapult’s thrust-time performance is measured on a stand. This gives you thorough, repeatable, quantified evidence that every element works and works together, so that on the day a pilot actually pulls the handle — the one time it is ever used for real — there are no surprises. Live sled or track testing has its place in a full programme, but the ground facility is where the engineering confidence is built.

Q · 03 What are the “occupant injury loads”, and how do you measure them?

They are what the escape does to the human body — and they are the real pass/fail. An ejection subjects the pilot to very high, very fast accelerations, and a seat can survive the event structurally while still injuring — particularly the spine, neck and head. So the seat is tested with an instrumented anthropomorphic test device — a crash-test dummy of representative mass and geometry — fitted with accelerometers and load cells at the head, neck and spine. During each test these record the accelerations and forces the occupant experiences, and the results are compared against established injury criteria such as the Dynamic Response Index (DRI) for spinal load and the Head Injury Criterion (HIC). Only if those numbers stay within limits does the seat pass, because a seat that ejects cleanly but breaks the pilot’s back has not done its job. The instrumented dummy is a bought-in specialist device; what we engineer is the rig it sits in, the way it is mounted and loaded, and the measurement and data chain that turns the event into trustworthy numbers.

Q · 04 How do you handle the catapult and rocket motor on a test facility?

We treat it purely as a thrust-measurement problem, the same way an engine or rocket test stand does. A seat is accelerated by a catapult and often a sustainer rocket motor, and what a test facility needs to know is the thrust-time performance — how much force is produced, and how it builds and decays over the milliseconds of the stroke — because that profile drives the loads on the seat and the occupant. So the facility includes an instrumented thrust stand that holds the unit and measures its force against time with load cells and high-speed data acquisition, exactly as a propulsion test stand measures an engine. The design and internal handling of the catapult and rocket motor themselves are the province of the seat manufacturer and the relevant certification authorities, not this facility; our scope is the measurement structure and instrumentation around them. That keeps the facility firmly in the machine-and-measurement domain, which is where Neometrix’s competence lies and where this capability sits.

Q · 05 Do you supply the crash-test dummies and cameras, or integrate them?

We integrate them — and we are clear about the split. The anthropomorphic test devices (the instrumented dummies), the high-speed cameras and the data-acquisition system are proprietary specialist products from established makers, selected for the injury criteria, frame rates and channel counts your programme needs. What Neometrix designs and delivers is everything that turns them into a working test facility: the drop tower and static test rigs, the restraint and harness test rig, the instrumented thrust-stand structure, the sequencing and functional-test controls, the mounting and fixturing for the seat and the dummy, the instrumentation integration and the safety, plus installation, commissioning and acceptance. It draws on the same test-facility and instrumentation-integration competence behind our other aerospace and life-safety systems. To be plain about status: this capability is offered turnkey and quoted against aircrew-escape test-facility requirements; no specific delivered facility is claimed on this page.

Q · 06 Can it cover overhaul (ROH) acceptance as well as new qualification?

Yes — and for many operators that is the day-to-day value. Ejection seats have a service life and a maintenance cycle: they are periodically stripped, inspected, have time-expired items replaced and are reassembled — a repair-and-overhaul (ROH) process — after which the seat must be proven to still function correctly before it goes back under a pilot. The functional and sequencing rig is exactly what an overhaul line needs for that acceptance: it confirms, on the ground and without a live ejection, that the escape sequence, timing, interlocks, restraint release and life-support all work as they must, so a returned-to-service seat is verified rather than assumed. So the facility serves two audiences from the same core rigs — a design-and-qualification programme proving a new or modified seat to standard, and an overhaul line giving each maintained seat a repeatable, documented functional acceptance. We scope and size the rigs to whichever of those — or both — you need.
