Abstract : The fatigue behaviour of a total of 21 port and starboard Vampire wings has been investigated for a 12 load level programmed loading sequence, representative of an average Australian flight loading spectrum. An additional two wings were subjected to a randomised sequence of these loads. This report describes the investigation and furnishes information on the following aspects: the fatigue life of major components in the wing; the ineffectiveness of replacing Parker-Kalon self tapping screws in the spar boom with pinned Chobert blind rivets; the increase in fatigue life achieved by replacing the lower spar boom; the residual strength of the cracked structure; the distribution of strain between screwed panels and the spar boom; and the fatigue resistance of glued wooden fuselages.
