Abstract

Abstract

This paper presents a progress in aircraft engine vibration monitoring and diagnosis in flight.Essentiality of the in-flight vibration monitoring and vibration source analysis and the features of the system used are discussed.An airborne vibration data acquisition unit,the ground analysis equipments and the method for analysing vibration signal are given.Its applications prove that it is feasible for vibration signal recording in flight and frequency spectrum analyzing.
