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.
