The Challenge
Our client, a Maintenance, Repair, Overhaul (MRO) repair station for aircraft hydraulic pumps, faced a critical challenge. They needed a specialized hydraulic test stand to perform Acceptance Test Procedure (ATP) testing on their repaired pumps. This project presented significant engineering hurdles. First, the multi-port pumps themselves are complex, featuring numerous fluid flow paths. Second, the test stand had to accurately simulate a precise electro-hydraulic aircraft environment. Finally, the design needed to integrate various customer-supplied hardware components, some of which were used, adding another layer of complexity to the development of this custom aircraft hydraulic test stand.
The core challenge was to deliver a solution that could rigorously verify 100% of the functional requirements of the pump, mirroring its actual operational conditions in an aircraft hydraulic test stand environment.
The Solution
ACS responded by engineering and manufacturing a robust, stand-alone hydraulic test stand crafted from stainless steel. This custom solution was meticulously designed to provide the multi-port hydraulic pump with a precisely simulated electro-hydraulic environment, accurately matching its operational use in aircraft applications. A key innovation in this hydraulic test stand was its ability to simulate various sea-level conditions through the controlled application of both vacuum and liquid nitrogen, ensuring comprehensive performance validation. Integrating the customer-supplied hardware required sophisticated design and assembly techniques, all managed by ACS’ expertise.
The resultant aircraft hydraulic test stand system ensures a rigorous verification of 100% of the pump’s functional requirements, guaranteeing its readiness for critical aerospace applications. ACS’ comprehensive services encompassed the entire lifecycle: design, engineering, manufacturing, assembly, and rigorous Factory Acceptance Testing (FAT) for this specialized aerospace component testing apparatus. The hydraulic test stand aircraft solution meets the unique demands of pump validation, which was a critical need for the MRO.
The Outcome
The successful implementation of the new hydraulic test stand has significantly enhanced our client’s operational capabilities. This state-of-the-art system empowers the client to efficiently meet the stringent capacity demands and rapid turnaround time requirements set by their customers. Beyond mere compliance, the test stand has demonstrably improved overall performance through a significant reduction in set-up time and marked ease of use for technicians. The ability of this test stand to verify 100% of the functional requirements of the hydraulic pump in a simulated aircraft environment ensures unparalleled reliability and confidence in their repaired units, solidifying their reputation as a leading MRO. The client now possesses a highly efficient hydraulic test stand aircraft solution.
