Universal Aircraft Hydraulic Component Test Bench HCT-20

The Universal Aircraft Hydraulic Component Test Bench (Model HCT-20) manufactured by Hydraulics International, Inc. (HII) is a state-of-the-art hydraulic testing system designed to provide comprehensive performance evaluations and certifications of various aircraft hydraulic components. The HCT-20 is engineered to support commercial, military, and general aviation sectors, offering robust testing capabilities that ensure compliance with rigorous aviation standards and safety regulations.

This sophisticated test bench is capable of conducting extensive functional tests on a wide array of aircraft hydraulic components, including actuators, pumps, motors, control valves, accumulators, servovalves, and hydraulic cylinders. It delivers precise, controlled hydraulic pressures typically ranging up to 5000 PSI or higher, depending on operational requirements. The system’s flow rate is adjustable, with capabilities often ranging between 0.5 to 30 gallons per minute (GPM), allowing technicians to simulate realistic operating conditions during tests.

At the core of the HCT-20 is a powerful electric motor-driven hydraulic pump, providing consistent and stable fluid delivery. The electric-driven design ensures quiet operation, environmental friendliness, and lower maintenance requirements compared to traditional diesel-driven units. Additionally, the unit is equipped with advanced proportional valves and sophisticated control technology that permits accurate regulation of hydraulic pressures and flow rates during testing scenarios.

The HCT-20 incorporates an advanced filtration system, employing both high-pressure (approximately 2-3 micron) and low-pressure (typically around 25 microns) filters. This system maintains exceptional hydraulic fluid cleanliness, essential for ensuring test accuracy and protecting sensitive aircraft components from particulate contamination and premature wear. Fluid compatibility spans standard aviation hydraulic fluids, such as MIL-H-5606, MIL-H-83282, Skydrol, HyJet, or other customer-specific fluids.

Instrumentation on the HCT-20 includes high-precision digital gauges, flow meters, temperature sensors, and integrated data acquisition systems for real-time monitoring, analysis, and recording of component performance metrics. Its intuitive human-machine interface (HMI) and programmable logic controller (PLC) allow operators to configure, execute, and replicate custom testing routines, significantly streamlining workflow processes.

Built for durability and continuous operation within rigorous maintenance and manufacturing environments, the HCT-20 features a robust, heavy-duty structural framework constructed from high-quality materials. Its ergonomic layout ensures ease of accessibility for component connection, servicing, and calibration. Integrated safety features such as pressure relief valves, emergency stops, and safety interlocks enhance operator safety and protect the tested components from potential overpressure or misuse incidents.

Applications:

• Maintenance, Repair, and Overhaul (MRO): The HCT-20 is ideal for verifying the operational integrity of hydraulic components during scheduled maintenance or after repairs, ensuring components conform to precise OEM standards prior to installation in aircraft.

• Aircraft Manufacturing: It facilitates rigorous quality assurance procedures during the manufacturing process, confirming that newly produced hydraulic components meet stringent performance and reliability standards before installation on new aircraft.

• Research and Development (R&D): The test bench supports the development of new hydraulic components and technologies, allowing engineers to simulate realistic operational conditions and collect critical performance data.

• Training and Certification: Aviation training centers utilize the HCT-20 to provide practical, hands-on experience to maintenance personnel, enhancing skills and competencies in hydraulic component testing and troubleshooting.
