A comparison is made betwen the fatigue performances of several sheet and forging materials under gust spectrum loading representing the lower wing surfaces of commercial transport aircraft. The materials are 2024-T3 and 7075-T6 aluminium alloy sheet, annealed Ti-6Al-4V sheet, and 7050 and AZ 74.61 aluminium alloy forgings. The significance of the results for the design of panel concepts and forged fittings is discussed, and proposals for further testing are made. (Biller)
