Testing for excellence
Parker HSD offers its customers the advantages of more than a decade – and tens of thousands of hours – of in-depth system rig and aircraft ground and flight test experience. This is in addition to over a half century of component performance and environmental testing experience.
System simulation rigs
Our experts begin by defining the types of system tests that are to be performed on customer test rigs. We then perform complete systems testing, correlating our analysis results with ground and flight test results. Our fully automated system simulation rigs include complete hydraulic systems integrated with actual or simulated landing gear, steering, brakes, flight controls, and thrust reverser systems, duplicating actual aircraft conditions as closely as possible for accurate results.
Notable programs that Parker has supported with full system testing include the Bombardier Global Express, CRJ700, Q400, and Challenger 300, as well as the Dassault Falcon 7X, the Airbus A350, and the Embraer regional jets.
7x results for lighter flight
Working closely with Dassault engineers, we simplified the hydraulic system on the 7X, resulting in a 40-percent weight reduction from the original concept. The hydraulic test rig and its control panel at Parker’s facility were critical to the process.
Aircraft ground and flight testing
Parker Aerospace also has significant experience supporting on-site flight testing. We routinely perform both ground tests and flight tests to demonstrate system performance and compliance with airworthiness regulations. Parker Aerospace engineers define the tests to be performed, and assess and report the results. Tests commonly performed include:
- Ground tests
- Pump startup and shutdown
- Reservoir mapping, high and low level
- High-pressure operation
- Pump pressure ripple Flight tests
- Mission profile and pressure transient survey
- Pump failures and backup operation (including RAT operation)
- Vibration survey
- System high and low temperature
