Abstract: To enhance the efficiency and quality of aerodynamic shape scheme design of missiles, the aerodynamic shape design, aerodynamic characteristics estimation, trajectory simulation and dynamic characteristics analysis are combined based on integrated design. The correlations among aerodynamic shape parameters, aerodynamic coefficients, dynamic coefficients and dynamic characteristics parameters are analyzed, and the rule how the aerodynamic shape parameters affect dynamic characteristics parameters is studied. The conclusion that the dynamic characteristics parameters can be changed by changing relevant aerodynamic shape parameters is verified by calculation and simulation.
