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

2014-05-29
CURRENT
AIR1666B
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.

AIR1749A
The information in this document is limited to aircraft engine fuel feed, refueling, and transfer components. It is assumed that isothermal, liquid fluid conditions exist, herein referred to as fuel. Where a unit of measure is suffixed, this is intended to show a generally associated unit for illustration only and is not an exclusive endorsement of this particular term. Where applicable and allowable it is understood that a referee fluid may be substituted for fuel.

Aircraft/Engine Fuel Pump Two Phase (Slugging Flow) Inlet Performance Test and Evaluation

1994-09-01
CURRENT
ARP4028
This procedure is intended to apply to all engine or airframe mounted fuel pumps and controls when required by the applicable specification. The procedure recommends a recirculation system similar to ARP492 to control the fuel properties affecting the fluid and its ability to "release" fuel vapors and dissolved air and have these "re-entrained or dissolved" during the fluid recovery process back to the tank and the original starting conditions.

Aircraft/Engine Fuel Pump Net Positive Suction Pressure Performance Test and Evaluation

1994-05-01
CURRENT
ARP4024
This procedure applies to engine or airframe-mounted fuel pumps. The procedure recommends single-pass operation to minimize changes in fuel properties affecting NPSP capability. An optional method using a recirculation system is also included and may be specified at the discretion of the equipment specification. This procedure defines the recommended test setup, test procedure, data acquisition, and data presentation.
