The Integrated Test Rig for Pumps and Fuel Coolers (ITRP) is a high-performance, multi-functional testing system built to validate the performance of key aero engine components — the LP Pump, HP Pump, Oil Pump, and Fuel Cooled Oil Cooler (FCOC) — prior to integration on the HTFE-25 aero engine. Engineered for aerospace applications, the rig supports both individual and combined testing of these units under real-world operating conditions, including high-speed, high-pressure, and high-temperature scenarios.

It features dual insulated power packs (OX-27 oil and ATF), precise fluid control systems, dedicated heating up to 200°C, and an advanced real-time data acquisition system for performance monitoring.

Individual LRU testing or full system-level integration — on one common test bed.

Ideal for both R&D and production environments, the rig ensures reliable, safe, and accurate qualification of aviation components before they are cleared for engine fitment.

Architecture

Two power packs, one common bed.

The rig is laid out around two independent power packs flanking a shared, high-speed test bed — every subsystem controlled and monitored from a single instrumented panel.

Modern fuel systems demand reliability, efficiency, and precise thermal management. To meet these needs, industries employ Combined Pump & Cooler Test Stands and Integrated Testing Systems for Fuel Coolers that validate both pumping performance and heat exchange capability.

A Pump and Cooler Assembly Test Rig or Multi-Component Thermal Fluid Test Bench enables dual-function testing of flow and cooling efficiency. With platforms such as the Fuel Pump and Heat Exchanger Test System and Thermal Flow and Pressure Validation System, engineers can simulate real operating conditions and ensure component durability.

Flexible solutions like the Modular Fuel System Test Unit, Hybrid Pump and Cooler Testing Bench, and Automotive Fuel Cooler Test Platform support both R&D and production quality checks. Advanced setups, including Closed-Loop Thermal Test Rigs and Fuel System Integration Benches, provide precise evaluation of cooling efficiency, durability, and fluid transfer capacity.

These integrated test benches form the backbone of modern validation processes, ensuring fuel systems achieve high performance, safety, and long-term reliability.
