Aircraft Engine Fuel Pump Cavitation Endurance Test
ARP492
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).<p>If any of the above conditions do not apply, refer to Section 2.<p>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.<p>This test is not intended to establish altitude or climb rate, starting, or other transient performance of the article tested.
Rationale: The SAE AE-5B committee had discussed that the revision of ARP492 should - include contemporary jet fuels, such as ASTM D1655 Grades Jet A, Jet A-1, MIL-DTL-83133 Grade JP-8 and GOST 10227 Grades TS-1, RT and Chinese No3 fuel etc.. -. A team was set up to tackle the update of ARP492 and related AE-5B Committee documents in year 2015 that deal with two phase flow in aircraft/engine fuel systems.
It is understood that the two–phase empirical equation was originally provided by the Coordinating Research Council (CRC). It was agreed, based on discussion with the Boeing representatives on the AE-5B committee, J.P. on the CRC Aviation Fuels committee to support the revision of ARP492 and associated AE-5B two-phase flow standards such that they address and include the principal - jet fuels.
The AE-5B team handling ARP-492 and related AE-5B two-phase flow standards had requested the CRC to collect available data and put it into an appropriate format for inclusion in future editions of the CRC Handbook of Aviation Fuel Properties. This will also be used for revision of ARP-492 and related AE-5B Standards. CRC finished the report of fuel test that was released in March 2022 at CRC website shown as below.
