Lightweight hydraulic system extended endurance test
Abstract
A 100 hour endurance test completed in a prior project was extended to 200 hours. The evaluation was conducted at 8000 psi and -200 F on hydraulic components in a laboratory system designed to be representative of aircraft-type circuitry. The hardware cycled were: pump, relief valve, restrictors, solenoid valves, flow control valve, seals (22), hydraulic fluid (MIL-H-83282), tubing, fittings, and hoses. The test was completed satisfactorily.
