Abstract:

The report evaluates the flight spectra data for three vastly different types of helicopters flown under combat conditions in Southeast Asia the AH-1G, a high-speed gunship the CH-54A, a heavy-lift helicopter and the OH-6A, a light, highly maneuverable observation helicopter. The flight spectra data for these three ships were compared to one another, to flight spectra data obtained from other helicopters, and to the spectrum shown in Appendix A of Civil Aeronautics Manual 6. The relationship to empirical fatigue substantiation spectra used to establish component service lives for these three helicopters is also shown. Evaluations and correlations of these spectra are presented where variations occur, their probable cause and possible effects on fatigue life are discussed.
