Abstract: A new integrative data analysis technique is presented and is used in an accurate nonlinear simulation to analysis spin characteristics of an airplane. By integrative factor methodology in aerodynamic coefficient building, it is reasonable to resolve the total rotation vector into a component along the velocity vector and components about three body axes. The component of rotation along the velocity vector is used with the rotary balance test data and other components of the rotation vector are used with the forced oscillation test data. The varied test data is used integrately. The 6 DOF simulation results in the paper show that the results of integrative data analysis technique are consistent with those of the flying tests considerably.
