Definition of Pressure Surge Test and Measurement Methods for Receiver Aircraft
The test procedure applies to the refueling manifold system connectingn the receiver aircraft fuel tanks to the refueling source fuel pump(s) for both ground and aerial refueling. The test procedure is intended to verify that the limit value for surge pressure specified for the receiver fuel system is not exceeded when refueling from a refueling source which meets the requirements of AS1284 (reference 2). This recommended practice is not directly applicable to surge pressure developed during operation of an aircraft fuel system, such as initiating or stopping engine fuel feed or fuel transfer within an aircraft, or the pressure surge produced when the fuel pumps are first started to fill an empty fuel manifold.
Rationale: This is a good and useful document in concept. However, it is outdated and in need of an update. As Most of the references are cancelled and/or not available. The analysis references cannot be found. There are more current analysis codes/methods that can be provided. The refuel pressure values need to be harmonized with the recent work done within the SAE AE-5 committee to ensure consistency with other documents.
