Performance Evaluation of Fuel Filter Elements Utilized in Aircraft Gas Turbine Engine/APU Main Fuel Systems
This SAE Aerospace Information Report (AIR) reviews performance testing of fuel filter elements utilized in aircraft gas turbine engine/APU fuel systems and discusses a sequence of standard tests used to qualify fuel filter element performance. This allows both manufacturer and customer a common means to specify, control, and evaluate filter elements. The methodology discussed should be incorporated in fuel filter element specifications.
Rationale: Performance testing is necessary to assure that gas turbine engine/APU fuel filter elements retain their functional characteristics under operating conditions. Variation in filter element testing methods and requirements make comparison of performance test results difficult. In order to minimize these problems, this AIR describes standard filter element performance test procedures, allowing both manufacturer and customer a common means to specify, control, and evaluate filter elements. This document highlights recommended tests and the appropriate test sequence. The methodology discussed should be incorporated in filter element specifications.
