A hydraulic system for aircraft wherein at least one circuit includes two hydraulic pumps, at least one of which is driven by an engine that may suffer uncontained failure that can damage hydraulic lines close to the pump, is equipped with pressure sensors for the hydraulic fluid in the lines...
when an aircraft reports a hydraulic system failure, which of the following possibility is incorrect ()A.Large speed approach (up to 220 knots without flapped approach)B.Put down the landing gear by hand, and can not be recoveredC.The runway is occupied
The three independent hydraulic systems respectively supply the users indicated on the diagram. Between these systems, the users are shared in order to ensure the aircraft control, even if only one hydraulic system is inoperative. On the blue hydraulic system, the Constant Speed Motor/Generator (...

Vibrations in aircraft hydraulic pipeline system, due to multi-source excitation of high fluid pressure fluctuation and serious vibration environment of airframe, can cause the pipeline system vibration failures through overload in engineering field. Controlling the vibrations in hydraulic pipeline is a ch...

Failure analysis of delivery valve screw – hydraulic pump of an aircraftA failed delivery valve screw pertaining to hydraulic pump of an aircraft was forwarded to the laboratory for analysis. Fractographic study showed that the valve screw has failed by fatigue. There was multiple fa...
Hydraulic system contaminationis another major factor in hydraulic seal failure. It is usually caused by external elements such as dirt, grit, mud, dust, ice, and internal contamination from circulating metal chips, breakdown products of fluid, hoses, or other degradable system components. As most...
