Generation of a Representative Load Sequence for the Fatigue Testing of Macchi MB 326H Spar Booms.
Abstract
Testing techniques have been developed to allow more realistic load sequences. To take advantage of this, the design of such test sequences must also be improved and for several years large scale tests at ARL have relied on loads obtained from flight histories transformed as little as possible. In this way the probability structure of flight sequences can be restored. Until now however, the design of test histories has been almost entirely manual. This note describes the generation of histories by use of automatic data processing techniques and linear programming. The example used in this note is the Macchi centre section spar boom which is being tested under the design load history to supplement earlier data obtained under less realistic load sequences.
