The parameters of aeroelastic characteristics analysis of high-aspect-ratio composite wings using nastran

The changes of different trends respectively of the deflections and the static stability derivatives are calculated at the variety of attitude,dynamic pressure and Mach number.By comparison and analysis,the following results can be found:static stability derivatives are reduced as the increase of Mach number or dynamic pressure;and reduce is rapidly with the change of dynamic pressure,but slower with the change of Mach number.The deflections at the wing tip are changed with different trends at the single variable such as attitude,Mach number,and angel.The decreases of deflections are as the increases of attitude;the deflections are also increase as the increases mach number,but are more slowly;the increase of angel leads to the increase of the deflection.
