This procedure is intended to apply to all pumps downstream of engine inlet.

This procedure is intended to apply to all pumps down stream of engine inlet.

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.

The AIR is limited to a presentation of the historical background, the technical rationale which generated the V/L fuel condition interface requirement in specifications between the aircraft fuel delivery system and the aircraft engine fuel system, and limitations in the usage of the V/L concept.

This AIR discusses the history and development of endurance requirements, provides an analysis of test contaminant material and includes a discussion of future requirements.

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.

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.

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.

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.

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.

This metric 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. This ARP is intended as a guide toward a standard practice, but may be subject to frequent change reflecting experience and technical advances. Use of this AIR is not recommended where flexibility of revision is impractical. Anyone interested in current information on BOC developments and technology should contact the Coordinating Research Council (CRC) Aviation Group on Aviation Fuel Lubricity.

This document discusses descriptions of fluid contamination products. These contaminants are used for design evaluation and formal component qualification/certification testing. Such tests are routinely performed on candidate aircraft engine fuel and pneumatic system components. Typical of these components are fuel pumps, fuel filters, fuel controls, pressurizing valves, flow dividers, selector valves, and combustor nozzles. The purpose of this document is to recommend standard descriptions to be used by specification writers.

This specification covers the general design, testing, and safety requirements for aircraft tank mounted fuel booster pumps used for engine fuel feed, transfer, and jettison.
