The fatigue life of the TF89 tactical fighter aircraft is determined. Five representative mission profiles are evolved and proportioned to describe the life of the airplane. These form the basis of all subsequent calculations. Analysis of maneuver, gust and ground loads is undertaken to determine the normal and lateral load spectra that would be applied to the airplane during its service life. These spectra are used to perform S-N curve and fracture mechanics analyses of selected metal components to test them for compliance with the relevant defense standard.
