Description
Summary:To investigate the behavior of normal force and pitching moment characteristics for different angles of attack and spouting jet angles, a parametric study of a lateral-jet-controlled missile has been performed. For this purpose, a three-dimensional Navier-Stokes computer code, AADL3D, has been developed and validated. Based on results of the parametric study, pitching moment and normal force coefficients have been selected as the objective and constraint functions, respectively. The flight Mach number, the angle of attack, and the spouting lateral jet angle are the design variables. With implementation of a genetic algorithm for the global optimum and the response surface method, the design optimization of the lateral-jet-controlled missile has been performed to evaluate the most effective flight conditions for the missile control.
