NMX-DTTR-01 · ENGINEERED TO ORDER — GUN-CONTROL / STABILISATION TEST

Dynamic turret test rig. Tune the gun before the ground moves.

A gun-control system is only as good as its stabilisation when the vehicle is moving. This rig makes the ground move on demand: a six-axis motion platform holds an armoured-fighting-vehicle turret and drives it through roll, pitch and bounce — reproducing the disturbances of a vehicle at speed — while the instrumentation logs how the turret and gun hold their aim. Built around the customer’s turret, engineered to order in Noida.

Overview

A gun holds still while the vehicle does not.

Stabilisation is the whole art of a modern fighting vehicle’s gun: keep the sight and the muzzle on target while the hull pitches, rolls and bounces over ground at speed. You cannot tune that on a static stand, and you cannot tune it by driving the vehicle for every iteration. You need the turret still in the workshop, but the ground moving underneath it — repeatably, on command. That is what this rig is for.

Representative render — detail of the six-axis motion platform: a heavy steel moving frame on six electromechanical linear actuators anchored to a concrete base, with a cable loom running to a control cabin; no vehicle or weapon markings

Fig · 02 The motion platform — six-actuator moving frame (representative render)

The rig is a six-axis (hexapod) motion platform. The customer’s turret and its gun-control system bolt to a moving frame; six electromechanical linear actuators tilt that frame in roll and pitch and drive a vertical bounce, all above a concrete-anchored base frame stiff enough to react the loads a heavy turret throws at it. A real-time controller solves the platform kinematics — the length each actuator must take for a commanded posture — and replays programmable disturbance profiles that stand in for a vehicle running over ground.

While the platform moves, the data-acquisition system watches the turret answer: azimuth and elevation speed and acceleration, and the stabilisation error the gun-control system is fighting to zero. Because the turret has to keep traversing while it is measured, the signals come off it through a rotary base junction — a slip-ring path that lets the turret spin and the data flow at the same time. The turret is the customer’s; the rig around it, and the truth it measures, are ours to build.

The rig does not test whether the gun works. It tests whether the gun stays on target when everything under it is trying to throw it off.

Model · Customer-Furnished

The turret stays the customer’s

The turret and its gun-control system are customer-furnished; Neometrix engineers everything around them — the platform, the actuation, the controller, the instrumentation and the safe cell — and the interfaces are frozen jointly at design review. No turret data leaves the programme.

Engineering · Proven on Paper First

FEM before steel

A heavy turret on a tilting frame is a structural problem before it is a control problem. Static, modal and dynamic finite-element analysis of every frame and the concrete foundation is carried out and vetted at design review, so the platform is rigid and safe under the worst-case loads before anything is cut.

Instrumentation · The Real Output

Stabilisation error, logged

Speed, acceleration and position on both axes, plus the gun-control system’s stabilisation error, are logged continuously through the rotary base junction and rolled up for analysis — turning a test run into the numbers an engineer tunes the control loop against.

Architecture

Platform, controller, and the data path.

The block diagram is the rig as a system — the motion platform that moves the turret, the controller that commands it, the power that feeds the system under test, and the acquisition path that measures what comes back.

Arc · 01

Motion Platform

A moving frame on six electromechanical roller-screw actuators over a concrete-anchored base. Roller-screw drives are chosen for load capacity and speed; each actuator carries its own position sensor and a manual override for safe recovery on power loss, with locking at a commanded posture. Roll, pitch and a vertical bounce are produced; an optional load-sharing set of pneumatic equalisers shares the peaks under high acceleration.

Arc · 02

Controller & Profiles

The real-time controller solves the platform kinematics — the length each actuator must take to place the moving frame at a commanded roll and pitch — and converts recorded vehicle-motion profiles into platform motion. Speed and acceleration of the motion are adjustable; inclinometer feedback, limit switches and alarms keep every posture inside its safe envelope, and the controller logs test hours per turret.

Arc · 03

Acquisition & RBJ

A real-time data-acquisition system logs turret azimuth and gun-elevation speed, acceleration and position, and the stabilisation-mode errors the gun-control system reports — over CAN and Ethernet. Signals are tapped through a rotary base junction so the turret keeps traversing while it is measured; data lands on a rugged acquisition unit and an analysis workstation with redundant logging.

Arc · 04

Power, Cell & Safety

A regulated DC supply powers the system under test, separate from the rig’s own drives for clean maintenance. The whole line sits in a guarded, conditioned safe cell — toughened control cabin, CCTV monitoring, safety rails around the rotating envelope, emergency stops at the operator point and outside the zone, warning alarms and indicating lamps — because a heavy turret at full traverse is handled entirely from behind the guarding.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 How is this different from a driveline or gearbox test rig?

A driveline or gearbox rig loads and turns a component to measure torque, wear and efficiency. This rig does the opposite job: it holds a complete turret still in the workshop and moves the world underneath it, so the vehicle’s gun-control and stabilisation system can be tuned against realistic motion. The output is not a power or wear curve — it is how well the gun stays on target while the platform pitches, rolls and bounces. Different subsystem, different physics, different measurement.

Q · 02 Why a six-axis platform instead of a simple tilt table?

A vehicle on the move does not tilt on one axis at a time. It rolls, pitches and bounces together, and the stabilisation system has to reject all of it at once. A single-axis tilt table can set a static incline; it cannot reproduce combined, time-varying motion. A six-axis (hexapod) platform — a moving frame on six linear actuators — can place and move the turret in roll, pitch and vertical bounce simultaneously, replaying a disturbance profile that stands in for a real run. That combined motion is what actually exercises the control loop.

Q · 03 Do you need the turret’s design data to build the rig?

No. The turret and its gun-control system are customer-furnished, and we engineer the rig around a defined mechanical and electrical interface — mounting pattern, mass and inertia envelope, power and signal connections — that is frozen jointly at design review. We do not need, and do not hold, the internals of the turret or the control algorithm. That separation is deliberate: the customer’s system stays the customer’s, and the rig is a clean, instrumented boundary around it.

Q · 04 How do you measure the turret while it keeps rotating?

Through a rotary base junction — a slip-ring assembly at the base of the turret that carries power and data across a continuously rotating interface. Without it, cabling would wind up the moment the turret traverses; with it, the turret can spin through its full arc while the data-acquisition system keeps logging azimuth and elevation speed, acceleration, position and stabilisation error over CAN and Ethernet. The junction is specified to the channel count and ratings the measurement set needs.

Q · 05 How is a heavy turret handled safely on a moving platform?

The whole rig is designed around the assumption that a large mass is moving under power and must never be approached while it does. The structure is proven by static, modal and dynamic finite-element analysis — including the concrete foundation — before manufacture. Actuators lock at posture and carry manual overrides for power-loss recovery. The operator works from a guarded, conditioned cabin; safety rails ring the rotating envelope; emergency stops sit at the operator point and outside the zone; and warning alarms and indicator lamps signal every live operation. It is a test cell, not a shop-floor fixture.

Q · 06 What is the current status — and can you build to our specification?

The rig is engineered to order. The architecture on this page — six-axis platform, controller, acquisition, power and safe cell — has been engineered for an Indian defence research establishment, and it is sized and configured per contract to the customer’s turret class, tilt range, disturbance profiles and instrumentation.
