Simulation of Integrated Identification of Aerodynamic Parameters and Thrust of Cruise Vehicle

Considering the characteristics of thrust and aerodynamic coupling of the cruise vehicle, this paper proposed a method for integrated online identification and prediction of aerodynamic parameters and thrust of the supersonic cruise vehicle. The research object of this paper is supersonic cruise vehicle powered by solid rocket ramjet. The thrust model of solid rocket ramjet is established based on the thrust characteristic analysis, and the aerodynamic parameter model is established based on the modified wind tunnel test data. Then utilizing the real-time measurement data from the airborne sensor, the parameters of thrust and aerodynamics can be obtained online. The simulation results show that this method has high identification and prediction accuracy, and could provide a feasible solution for online identification and prediction of the performance parameters of the supersonic cruise vehicle.
