The flight path of a vehicle with large wing is affected more obviously by the disturbance flow field in separation from the parent aircraft, and the precision of the aerodynamic disturbance database is demanded to be further improved. A simplified dispersion aerodynamic parameter model is put forward and a series of flight data estimation methods are introduced, combining the characteristics of the aerodynamic disturbance in separation. The flight data identification result and the six-degree-freedom flight dynamic simulation result show that the aerodynamic model and flight data estimation methods proposed in this paper are effective. The precision of the aerodynamic database is improved by correcting with the identified dispersion aerodynamic parameter model, and the precision of the flight simulation for separation safety analysis can be also improved.
