To the flight dynamic problems of a coupled rigid-liquid rotating liquid-filled system, based on the government equations obtained from the variational principles in mechanics, the complete flight motion state equations are introduced and its simulating models is established. The liquid moments acting to system can be obtained by the numerical solutions of Navier-Stokes equations and the liquid flow characteristic of inertial wave oscillation. Through the simulating experiments and the analysis of angle motion time series, the detailed analyzed conclusions about flight instability mechanism are presented.
