-
ENTRAPPED AIR IN A CLOSED HYDRAULIC SYSTEM, PRESSURIZED ABOVE WHAT PSI, BECOMES COMPRESSED INTO SOLUTION?
50PSI
-
MOST HYDRAULIC SYSTEMS IN HIGH PERFORMANCE AIRCRAFT ARE OF WHAT TYPE AND ARE DESIGNED TO ALLOW FREE AIR PROVIDED IT IS NOT TRAPPED BEHIND A PISTON ROD, CHECK VALVE, OR ISOLATION VALVE, TO SELF SCAVANGE BACK TO THE SYSTEM RESERVOIR WHEN A SYSTEM IS DEPRESSURIZED?
CLOSED TYPE
-
WHAT VALVES ARE SOMETIMES PROVIDED AT HIGH POINTS IN THE AIRCRAFT CIRCULATORY SYSTEM, FILTER ASSEMBLIES, AND REMOTE SYSTEM COMPONENTS SUCH AS ACTUATORS, TO FURTHER FACILITATE REMOVAL OF FREE AIR?
AIR BLEED VALVES
-
WHAT IS A DECONTAMINATION PROCESS IN WHICH THE SYSTEM TO BE CLEANED IS POWERED FROM A CLEAN EXTERNAL POWER SOURCE AND CYCLED SO AS TO PRODUCE A MAXIMUM INTERCHANGE OF FLUID BETWEEN THE POWERED SYSTEM AND THE SE USED TO POWER IT?
RECIRCULATION CLEANING
-
WHAT IS THE PROCESS OF REMOVING PARTICULATE, AIR, WATER, AND VOLATILE CONTAMINANTS FROM THE HYDRAULIC FLUID WITHOUT ALTERING THE PHYSICAL OR CHEMICAL PROPERTIES?
PURIFICATION
-
WHAT IS A DECONTAMINATION METHOD IN WHICH CONTAMINATED SYSTEM FLUID IS REMOVED TO THE MAXIMUM EXTENT PRACTICABLE AND THEN DISCARDED? FILTERED FLUID IS USED TO DISPLACE CONTAMINATED FLUID, THUS REPLACING IT.
FLUSHING
-
WHAT IS A DECONTAMINATION PROCESS IN WHICH THE AIRCRAFT HYDRAULICS SYSTEM IS DRAINED TO THE MAXIMUM EXTENT PRACTICABLE AND THE REMOVED FLUID DISCARDED? HYDRAULIC SYSTEM IS CLEANED WITH CLEANING AGENT THEN REPLACED WITH NEW HYDRAULIC FLUID
