| Abstract: | After a modified version design according to the original aircraft, due to the changes of weight and center of gravity, it can lead to the changes of load on remodeled aircraft landing gear. This paper presents landing gear detail fatigue rating (LGDFR) method to finish the fatigue strength analysis of military aircraft landing gear,used the fatigue test data based on the landing gear detail fatigue rating . The method is simple, reliable and practical. |
