Aerospace Hydraulic Pump / Motor Test Bench

English Aerospace Hydraulic Testing Solutions Ensuring the reliability and performance of hydraulic systems is critical in aviation. The aerospace hydraulic pump test bench and aircraft hydraulic motor test bench provide precise evaluation of pumps and motors under operational conditions. These platforms support aviation hydraulic pump testing and utilize advanced aerospace hydraulic testing equipment to validate component performance. Specialized rigs, such as the axial piston pump test rig and the aerospace hydraulic qualification system, enable thorough assessment of endurance, efficiency, and reliability. Additional setups, including aircraft hydraulic endurance testing and the aerospace hydraulic calibration rig, ensure components meet rigorous aerospace standards. Through hydraulic pump reliability testing and aircraft hydraulic performance validation, these systems guarantee the safe and efficient operation of hydraulic components across a wide range of aerospace applications.

About

The Aerospace Hydraulic Pump / Hydraulic Motor Test Bench is a fully automated, precision-engineered validation system that plays a decisive role in ensuring the safety, reliability, and mission readiness of aircraft. Designed for testing variable delivery axial piston pumps with integrated pressure compensators, it replicates the harshest real-world aerospace conditions with capabilities of up to 270 bar pressure, 130 LPM flow, and 6000 RPM speed. The bench executes an extensive range of tests — including proof pressure validation, endurance cycling, compensator calibration, stability assessment, and open/close actuation — to expose hidden weaknesses and verify component robustness across the entire duty spectrum. Beyond its technical features, its criticality lies in its function as the final quality checkpoint for aerospace hydraulics, where any underperformance can be detected and eliminated before installation in combat or transport aircraft. By preventing in- service hydraulic failures that could compromise flight control systems, landing gear operations, or weapons deployment, this test bench safeguards pilots, protects high-value aircraft assets, and guarantees the operational integrity of modern air forces.

Introduction
In aerospace and defense systems, hydraulic power is the backbone of mission-critical operations. It enables precise actuation of flight control surfaces, deployment of landing gear, braking and steering systems, weapons release mechanisms, and many other essential aircraft subsystems. Any malfunction in a hydraulic pump or motor can jeopardize the entire mission and compromise pilot safety. This makes it imperative that hydraulic components undergo rigorous qualification and endurance testing before being cleared for deployment.

The Aerospace Hydraulic Pump / Hydraulic Motor Test Bench is a state-of-the-art, fully automated validation platform built to replicate the extreme operating conditions encountered by combat and transport aircraft. Specifically engineered to test variable delivery positive displacement axial piston pumps with integrated pressure compensators, this system subjects units to high pressures (up to 270 bar), high flow rates (130 LPM), and high speeds (up to 6000 RPM) — conditions that mirror the harshest aerospace hydraulic environments.

By integrating advanced instrumentation, real-time monitoring, automated data acquisition, and precision control systems, the test bench ensures that pumps not only achieve but sustain their rated performance. It acts as a critical gatekeeper of quality and reliability,
ensuring that only thoroughly validated pumps are installed in mission platforms such as the Light Combat Aircraft (LCA).
