Gives information on hydraulic systems fitted to commercial aircraft.

This SAE Aerospace Information Report (AIR) has been compiled to provide information on hydraulic systems fitted to commercial aircraft.Data has been provided for following aircraft types:aWide body jet airlinersbNarrow body jet airlinerscTurboprop/commuter aircraftdBusiness jet aircraftThe airliners that have been included in this document are generally in operational service with either airlines or cargo operators. Information on aircraft that have been retired from in-service use has been included for reference purposes. No information is presented for aircraft that are currently being developed.The following information is provided for each aircraftDesign requirements: Governing airworthiness regulationsSystem pressure: Fluid power system operating pressureHydraulic fluid: Type of fluid the hydraulic system usesNumber of hydraulic systems: Number and identification of independent hydraulic systemsSystem temperature: Minimum and maximum design operating temperaturesMain hydraulic pump data: Flow, pressure, displacementAuxiliary pump data: System auxiliary pump or back-up dataHydraulic motor data: System hydraulic motor requirementsAccumulator data: Usage, volume and precharge requirementsReservoir data: Type, volume and pressureRelief valve data: Usage, crack and reseat pressures, rated flowFiltration data: Usage, filtration ratingTubing data: Materials, sizes, wall thicknessesFitting data: Type, size range, materialSchematic diagram: System architecture, services supplied
