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 purpose of this Aerospace Recommended Practice is to standardize test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. This document is divided into the following sections: 1 Definitions and Terminology 2 Equipment 3 Test Procedures 4 Information and Data to be Recorded 5 Data Reduction and Analysis 6 Presentation of Results
This Aerospace Recommended Practice (ARP) standardizes test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. Tests have indicated that the practically achieveable precision of the smoke number is within ±3 when the system is properly used as outlined herein. This procedure is not intended for in-flight testing, nor does it apply to afterburning engines. This ARP is divided into the following sections: 2 Definitions and Terminology 3 Equipment 4 Test Procedures 5 Information and Data to be Recorded 6 Data Reduction and Analysis 7 Presentation of Results 8 Comments
This 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 life. ARP1827 is recommended for filter evaluation.
This specification establishes the common requirements for variable delivery, hydraulic pumps, suitable for use in aircraft; and the methods to be used for demonstrating compliance with these requirements.
