摘要

Recent survey concludes that fatigue failure results in many fatal accidents to the aircrafts. So in order to reduce fatigue failure, static stress and fatigue analysis have been done for vertical stabilizer of a typical trainer aircraft at +4g factor condition. Design modeling of component is done using CATIA V5 software. Static stress analysis has been done using Patran and Nastran software. Aluminium 7075 T6 material which has high fatigue strength has been used in vertical stabilizer. From the static stress analysis, maximum principal stress value has been found out which is less than the yield strength of Al 7075 T6. The maximum principal stress value has been used in fatigue calculation and the obtained analytical result shows the safe number of factored fatigue life hours for the component. The result predicted in this work concludes the efficient number of factored fatigue life hours for the vertical stabilizer which would reduce the service cost of the component and ensures structural safety to the component.
