APPARATUS FOR ESTIMATING VARIABLE AERODYNAMIC FORCE OF FLIGHT VEHICLE AND METHOD THEREOF

摘要

The present invention relates to an apparatus for predicting the aerodynamic variation of a flight vehicle and a method thereof, which can predict an aerodynamic variation due to a lateral jet over the entire operation range of a side jet thruster of a flight vehicle and reduce time and cost required for the prediction. The apparatus for predicting the aerodynamic variation of a flight vehicle comprises: a discretization module for discretizing variables, which determine the aerodynamic variation of the flight vehicle, to minimize temporal and material resources required for the prediction of the aerodynamic variation of the flight vehicle; a function calculation module for calculating correlation functions between the aerodynamic variation and the discretized variables; and a prediction module for predicting the aerodynamic variation of the entire operation range of the side jet thruster from the correlation functions.
