A review of a fatigue failure with aircraft engine nacelle components
A review of a fatigue failure with aircraft engine nacelle components
The paper discusses some of the fatigue problems observed in-service with components on aircraft engine nacelles. Acoustic fatigue (or sonic fatigue) has been an issue with nacelle components given the proximity of the structure to the high intensity noise generated by the fan on modern high bypass ratio gas turbine aircraft engines.
Reference is made to test measurements – both full scale engine testing and sub-element component testing. Theoretical result predictions using finite element models are summarised and compared with the test measurements. The dynamic stiffness method is also used to predict the fundamental frequency and strain response and shows good agreement with test data.

Abstract
The paper discusses some of the fatigue problems observed in-service with components on aircraft engine nacelles. Acoustic fatigue (or sonic fatigue) has been an issue with nacelle components given the proximity of the structure to the high intensity noise generated by the fan on modern high bypass ratio gas turbine aircraft engines.
Reference is made to test measurements – both full scale engine testing and sub-element component testing. Theoretical result predictions using finite element models are summarised and compared with the test measurements. The dynamic stiffness method is also used to predict the fundamental frequency and strain response and shows good agreement with test data.
