Keywords: aeroelasticity, transonic flutter, LCO

In order to make better agreement with transonic wind tunnel experimental data, which was obtained in the Japan Aerospace Exploration Agency (JAXA) in 1990’s, we proposed new mathematical model to improve the previous model. The bifurcation diagram was analyzed by a continuation method.
