Abstract:

By analyzing the dynamic characteristics and the dynamic response of composite structural members of aircraft wings, the article presents the methods and steps for computational analysis, as well as further processing of the analytical results, in addition to suggestions for design improvements. It was found that improved lamina design can eliminate design weakness since local vibration phenomena were discovered in the prototype design when the dynamic characteristics of structural members were analyzed. By comparing three computational missile launch variants for outboard wing, mid-wing, and inner- wing, the values of the dynamic response in the most serious situation are given. Finally, the dynamic strength is determined.
