Lessons Learned While Measuring Fuel System Differential Pressure

Abstract

A recent aircraft project required the measurement of differential pressures across a fuel filter during engine operation. Early testing showed intermittent noise in the system. Additionally, transducers were failing. Attempts to troubleshoot the problem led to the discovery of unexpected large pressure transients within the fuel system which were causing the "noise" and damaging the transducers. Attempts were made, with some success, to gather the data without extensively modifying the existing system. This presentation provides a brief review of what was done and what was learned from this program.
