Abstract

Abstract: The variable sweep angle of missile wing is an important variant missile design scheme. In the process of variant design, the aerodynamic and flutter characteristics of missile will be significantly different by using different variable sweep methods. Referring to the shape characteristics of Tomahawk missile, the geometric model of variable sweep wing missile is established. The flutter characteristics of variable sweep wing missile under different variable sweep angle modes are calculated and analyzed by fluid structure coupling method, and the selection scheme of variable sweep wing mode based on flutter characteristics is explored. The results show that the flutter deformation of "rotation variable sweep" and "shear variable sweep" configurations converges with the increase of coupling time at low speed; in subsonic and transonic conditions, because the "shear variable sweep" configuration has the possibility of flutter, which is more obvious at transonic speed, so the characteristic "rotation variable sweep" configuration is better.

Key words: variable swept wing, fluid structure coupling, flutter characteristics, simulation calculation
