Large Body Aircraft Accessories Test Stand

The Large Body Aircraft Accessories Test Stand, designated as A/F27T-12, is a comprehensive testing platform engineered to evaluate the functionality and performance of hydraulic components utilized in large-body aircraft, including next-generation models such as the Boeing 787, Airbus A380, and A350. This advanced test stand integrates the Main Hydraulic Console (MHC) and the optional Pump and Motor Test Console (P&MTC) to deliver a versatile and efficient testing environment for a wide array of hydraulic accessories.

Technical Details:

• Main Hydraulic Console (MHC):

  • High-Pressure Dynamic Circuits: Equipped with two independent circuits, each capable of delivering 20 gallons per minute (GPM) at 6,000 PSI or 25 GPM at 3,000 PSI, facilitating simultaneous testing of multiple components.​

  • Low-Pressure Dynamic Circuit: Provides up to 10 GPM at 250 PSI, suitable for components operating under lower pressure conditions.

  • Hydrostatic Circuit: Delivers pressures up to 10,000 PSI, accommodating high-pressure testing requirements.​

  • Power Supplies: Includes adjustable AC and DC power supplies to support various testing scenarios.​

• Pump and Motor Test Console (P&MTC):

  • Rotating Component Testing: Designed to assess the performance of hydraulic pumps, motors, and power transfer units. When integrated with the MHC, it utilizes the hydraulic flow and pressure supplied by the MHC for comprehensive testing.​

• Control and Interface:

  • Manual Control Modes: Allows operators to manually control testing parameters, providing flexibility and precision.​

  • Human-Machine Interface (HMI): Features a display that presents flow, pressure, temperature, calibration data, diagnostics, and warning signals for real-time monitoring.​

  • Programmable Logic Controller (PLC): Automates testing procedures, enhancing consistency and efficiency.​

Applications:

• Component Testing: Facilitates functional and operational assessments of hydraulic components such as actuators and control valves from both large and mid-size body aircraft.

• Pump and Motor Evaluation: When integrated with the P&MTC, enables thorough testing of hydraulic pumps and motors to ensure optimal performance.​

• Maintenance and Overhaul: Supports routine maintenance checks and overhauls by providing accurate diagnostics of hydraulic accessories.​

Technical Specifications:

By integrating the A/F27T-12 into maintenance and testing protocols, aviation maintenance facilities can ensure the reliability and safety of hydraulic components in large-body aircraft, thereby enhancing overall operational efficiency.
