Overview

Nozzle flow is a go / no-go test.

Every fuel nozzle and oil jet on an aircraft has to deliver fluid at the right rate, in the right direction, at the pressures and temperatures it will actually see in service. The Aerospace Nozzle Flow Test Bench (ANFT) replicates those conditions on the bench, so mass flow rate and flow direction can be measured and signed off before a nozzle ever reaches an aircraft.

Aerospace Nozzle Flow Test Bench — full test bench with refrigerated bath enclosure, HMI panel and electrical control cabinet

Fig · 02 control cabinet

The bench is built around a constant-temperature refrigerated liquid bath chiller with heater, with an inner test chamber of 500 × 400 × 400 mm in SS 304 and a main fluid reservoir capacity of 80 litres. This thermostatically controlled tank holds the working fluid — Turbonycoil 13 B aviation oil — at 35°C with an accuracy of ±0.1°C, across an overall temperature range of +5°C to +95°C.

Test pressure is held at 200 kPa ±10 kPa by an Equilibar low-pressure, low-flow-rate regulator, with fluid carried through stainless-steel (SS 304) flow lines for corrosion resistance and contamination control.

Mass flow rate and flow direction, measured under real thermal and pressure conditions — not estimated on paper.

A National Instruments (NI) data acquisition system logs every test parameter in real time, giving traceable, repeatable results for each nozzle or oil jet under test.

Architecture

Six subsystems, one flow test.

Thermal control, pressure regulation, flow control, and data acquisition are handled by discrete subsystems working together from a single control cabinet.

Sub · 01

Refrigerated Bath & Thermal Control

Constant-temperature refrigerated liquid bath chiller with heater. Inner chamber 500×400×400 mm in SS 304, 1.5-ton refrigeration compressor plus compressor-based heating, +5°C to +95°C range.

Sub · 02

Reservoir & Flow Lines

80-litre main reservoir with a low-fluid-level switch. Flow lines in stainless steel SS 304 carry Turbonycoil 13 B working fluid to the nozzle test cell.

Sub · 03

Pressure Regulation

Equilibar regulator for low-pressure, low-flow-rate control, holding test pressure at 200 kPa ±10 kPa for accurate, repeatable nozzle-flow measurement.

Sub · 04

Flow Control Valve

Ball valve with pneumatic actuator, normally open, single-acting with spring-return, giving fail-safe shutoff of the test line on loss of signal or air supply.

Sub · 05

Data Acquisition

National Instruments (NI) instrumentation logs temperature, pressure, and flow data in real time, with optional SCADA integration for centralized process control.

Sub · 06

Safety & Contamination Control

Multiple interlocks guard against high temperature, pressure surges, and fluid overflow. Contamination-preventing filters and limit-switch monitoring on the ball valve keep the fluid path clean and automated.

Fig · 03 Safety interlock panel — filter-clog, tank-level and emergency-stop indicators

Interlocked by design, not by procedure

Filter-clog sensors on both the 10-micron and 5-micron stages, drain-tank and main-tank level switches, and a front-panel emergency stop are wired directly into the control system — not left to an operator watching a gauge. Electrical control automates the spring-return ball valve, so an out-of-range condition shuts the test line down automatically rather than waiting on manual intervention.

The same panel carries the main-power isolator, transfer-pump control, and USB ports for the data-logging PC, keeping every operator control for a test run in one place.

Why nozzle flow testing matters

The Aerospace Nozzle Flow Test Bench is a high-precision, automated testing system designed to measure the performance characteristics of oil jets and nozzles used in aerospace applications. It determines both the mass flow rate and the directional behaviour of fluids under carefully controlled temperature and pressure conditions, ensuring that critical components meet stringent aviation and defence standards, and maintain safety and performance in high-stakes environments.

The primary functions include mass flow rate measurement and flow direction verification for nozzles and oil jets. The system replicates real-world operating conditions by stabilising fluid temperature and pressure with high precision, using Turbonycoil 13 B — a specialised aviation oil — circulated through stainless steel (SS 304) pipelines for durability and contamination resistance.

1. Thermal and fluid control system

The temperature of the fluid is maintained at 35°C with an accuracy of ±0.1°C using a refrigerated chiller and heating system, across an overall range of +5°C to +95°C. The cooling system has a 1.5-ton capacity, and a compressor-based heating system ensures stable thermal management. The main reservoir has a capacity of 80 litres, with a low-level fluid switch, ensuring adequate fluid supply during extended testing.

2. Pressure regulation and flow control

Pressure is controlled at 200 kPa (±10 kPa) with an Equilibar low-pressure regulator, ensuring accurate and repeatable measurements. An Equilibar regulator and spring-return ball valves with pneumatic actuators manage fluid flow and pressure, with limit switches providing enhanced automation of the test sequence.

3. Data acquisition and automation

National Instruments (NI) instrumentation monitors and logs real-time testing parameters. Data acquisition and control systems enable continuous logging of operational data, supporting post-test analysis and compliance with industry standards. The machine can also integrate with SCADA systems for centralised process control.

4. Automation and safety features

The machine includes multiple safety interlocks to prevent accidents from high temperature, pressure surges, or fluid overflow. Electrical control systems automate ball-valve operations, allowing technicians to manage flow and pressure settings remotely, while contamination is prevented through high-quality filters at the 10-micron and 5-micron stages.
