Abstract

There are many factors that cause the flutter of the wing of the aircraft, and one of the factors is the wing opening trepanning. In order to explore the changes of the flutter speed of the wing after trepanning, the software simulation method is adopted to analyze the flutter speed .MSC.Patran and MSC.Nastran are used to model the structure of the wing structure, and the aerodynamic model is modeled by them. Then, the two part of the structural model is coupled, and modalities of the wing are obtained. Through the analysis of the calculation results, the change of the flutter speed of the plane flat wing is obtained, which provides a reference for the control of most subsonic airliners wings.
