Performance Evaluation of Fuel Filter Elements Utilized in Aircraft Gas Turbine Engine/APU Main Fuel Systems

2019-09-11
WIP
AIR6985
This SAE Aerospace Information Report (AIR) reviews performance testing of fuel filter elements utilized in aircraft gas turbine engine/APU fuel systems and discusses a sequence of standard tests used to qualify fuel filter element performance. This allows both manufacturer and customer a common means to specify, control, and evaluate filter elements. The methodology discussed should be incorporated in fuel filter element specifications.

Performance Testing of Lubricant Filter Elements Utilized in Aircraft Power and Propulsion Lubrication Systems

2019-09-04
WIP
AIR1666C

This SAE Aerospace Information Report (AIR) reviews performance testing parameters for non-cleanable, often referred to as disposable, filter elements utilized in aircraft power and propulsion lubrication systems, including gas turbine engines and auxiliary power units (APUs), propulsion and transmission gear boxes, and constant speed drives and integrated drive generators (IDGs).

This document is confined to laboratory testing of filter element performance to qualify the filtration medium and filter element construction as opposed to qualification of the complete filter assembly. The testing discussed here is usually followed by laboratory and on-engine testing of the entire lube filter assembly (including filter element, housing, valving, etc.), which is outside the scope of this AIR.

Lubrication System Oil Tank Sizing

2018-02-26
WIP
ARP7976
This Aerospace Recommended Practice provides the considerations appropriate for Engine Lubrication System Oil Tank sizing, and provides means to confirm the oil volume held within the Oil Tank is adequate for satisfactory Lubrication System performance. Two scenarios should be considered when demonstrating that the Oil Tank capacity and oil volume held within the Oil Tank are adequate, sea level engine testing and in-flight operation, when demonstrating the capability of Lubrication System to operate in support of FAA Part 23 and Part 25, CFR Part 33, and corresponding EASA CS-E regulations, and equivalent Military application requirements.

Fire Testing of Fluid Handling Components for Aircraft Engines and Aircraft Engine Installations

2016-01-27
WIP
AS4273B
This document establishes requirements, test procedures, and acceptance criteria for the fire testing of fluid handling components and materials used in aircraft fluid systems. It is applicable to fluid handling components other than those prescribed by AS1055 (e.g., hoses, tube assemblies, coils, and fittings). It also is applicable to materials, wiring, and components such as reservoirs, valves, gearboxes, pumps, filter assemblies, accumulators, fluid-cooled electrical/electronic components, in-flight fluid system instrumentation, hydromechanical controls, actuators, heat exchangers, and manifolds. These components may be used in fuel, lubrication, hydraulic, or pneumatic systems.
