Focused on the characteristic of hypersonic aerodynamic, an approximately model was developed and applied to study nose local aerodynamic shape design based on Newton sine squared method. The generatrix of nose was fit by cubic spline and the relationship between the reference points and the aerodynamic was figured out. An optimum solution was presented to achieve the goal of minimize parameter Cx by solve Karush-Kuhn-Tucker function. A contrast between the optimum solution and commonly solution indicated that the method can approach the goal effectively.
Key words： optimization method; aerodynamic shape; spline
