Optimization Design of Aerodynamic Characteristics of Rudder by Genetic Algorithm

摘要

To get the demand for fast response of Trajectory Correction,the correction implementing mechanism needs great lift-drag ratio.Lift-drag ratio was optimized and simulated for rudder of telescopic steering gear of a model rocket by Genetic Algorithms.Simulation results show that optimized lift-drag ratio was improved compared to the previous ones,which provides a reference for design of rudder of the correction implementing mechanism of trajectory correction projectiles.
