| Abstract: | Aim at strength problem for ventral fins root material fatigue fracture on one type aircraft,based on the structure and working characteristics of the pelvic fins,quantitative analysis of ventral fins crack was proposed by using the theory of fatigue fracture.Ruled out possibility of damage that caused by the static load and dynamic load and the load was caused by aerodynamic in the flight,and the cause of aircraft ventral fins crack was analyzed and the maintenance suggestions were put forward. |
