Ball-On-Cylinder (BOC) Aircraft Turbine Fuel Lubricity Tester
2016-07-26
CURRENT
AIR1794B
This metric SAE Aerospace Information Report (AIR) details a ball-on-cylinder (BOC) test device and specifies a method of rating the relative lubricity of aviation turbine fuel samples. The BOC produces a wear scar on a stationary steel ball by forcing it with a fixed load against a fuel wetted steel test ring in a controlled atmosphere. The test ring is rotated at a fixed speed so its surface is wetted by a momentary exposure to the fluid under test. The size of the wear scar is a measure of the test fluid lubricity and provides a basis for predicting friction or wear problems.

Aircraft and Aircraft Engine Fuel Pump Low Lubricity Fluid Endurance Test
2014-12-11
CURRENT
ARP1797A
This procedure is intended to apply to fuel pumps. This procedure will be defined in terms of recommended test fluid, test setup, test conditions, and test method. This procedure may be used for other fuel system components, by testing in conjunction with the pump, which normally supplies the component inlet flow, or a substitute test pump of similar capacity. This procedure may be used, with variations in test conditions and test fluid for performing pump evaluation tests. Tests at progressively increasing pump speeds and pressures will provide design limitation data. Alternate test periods on a test pump and another pump, of a design for which actual service durability is known, will provide useful comparison data.

Performance Evaluation of Fuel Filter Elements Utilized in Aircraft Gas Turbine Engine and APU Main Fuel Systems
2021-06-10
CURRENT
AIR6985
This SAE Aerospace Information Report (AIR) reviews performance testing parameters for fuel filter elements utilized in gas turbine engine and APU main fuel systems. The scope is limited to main fuel filter elements rated at 35 μm(c), or finer, which constitute the majority of contemporary engine main fuel system filtration. This document does not address icing tests specific to fuel filter elements since they are only required for certain engine designs and are custom test procedures. General information on icing tests for aircraft fuel system components can be found in ARP1401. This document also does not address fuel filter elements utilized in fuel hydraulic systems since it is outside the scope of this document, 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 fuel filter assembly.

Aircraft/Engine Fuel Pump Two Phase (Slugging Flow) Inlet Performance Test and Evaluation
2020-04-29
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.

HISTORICAL
ARP492
This procedure is intended to apply to any aircraft fuel pump which supplies liquid hydrocarbon fuel either directly to an aircraft engine or to another pump mounted on an aircraft engine, except that it is not intended to apply to a fuel pump mounted in a fuel tank.

Aircraft Engine Fuel Pump Cavitation Endurance Test

WIP
ARP492D
This SAE Aerospace Recommended Practice (ARP) defines procedures for testing aircraft engine fuel pumps for the purpose of determining their resistance to deterioration, during steady state endurance test, while receiving MIL-T-5624 Grade JP-4 fuel as a homogenous mixture of gas and liquid expressed as a ratio of vapor volume to liquid volume (V/L).

If any of the above conditions do not apply, refer to Section 2.

The procedure recommended herein is based on experience gathered by a number of laboratories conducting component qualification tests to MIL-E-5009, currently MIL-E-5007. It is intended to produce a uniform reproducible steady state test condition for fuel pump cavitation testing as required by various military engine specifications.

This test is not intended to establish altitude or climb rate, starting, or other transient performance of the article tested.

Aircraft Turbine Engine Fuel System Component Endurance Test Procedure (Room Temperature Contaminated Fuel)
2022-05-02
CURRENT
MAP749C
This SAE Aerospace Recommended Practice describes a method for conducting room temperature, contaminated fuel, endurance testing when the applicable specification requires nonrecirculation of the contaminants. The objective of the test is to determine the resistance of engine fuel system components to wear or damage caused by contaminated fuel operation. It is not intended as a test for verification of the component's filter performance and service life. ARP1827 is recommended for filter performance evaluation.
