Effects of Parameters on Flutter of a Wing with an External Store

Abstract:

The flutter analysis of a wing with an external store is presented. Because of the external store, the concentrated store mass is combined into the governing equations which are obtained using the extended Hamiltons principle. Dirac function is used to precisely consider the location and properties of the external store. The k method is used to calculate the flutter velocity. The effects of store parameters such as store mass and inertia on the flutter velocity are investigated.
