FATIGUE TEST RESULTS AND ANALYSIS OF FOUR PISTON PROVOST WINGS TESTED IN AN ASCENDING-DESCENDING ORDER OF LOADING

Results of fatigue tests on four wings programme loaded in Lo-Hi-Lo order are compared with similar tests performed in Hi-Lo and Lo-Hi orders reported previously. The results lie almost mid-way between the results for Hi-Lo and Lo-Hi tests. No significant difference is shown in either the variance o...

Zusammenfassung:Results of fatigue tests on four wings programme loaded in Lo-Hi-Lo order are compared with similar tests performed in Hi-Lo and Lo-Hi orders reported previously. The results lie almost mid-way between the results for Hi-Lo and Lo-Hi tests. No significant difference is shown in either the variance or mean value since the results lie within the scatter of the previous tests. (Author)
