Analysis of the Operation Effect of the Simple Control System of Rockets

The principle of attitude control system adopted by some controlled rockets is summarized.Based on the uncontrolled rockets trajectory model,the trajectory model of simple controlled rockets is formulated.With which we have numerical simulated at four flight conditions including controlled rockets with thrust bias,controlled rockets with no thrust bias,uncontrolled rockets with thrust bias and uncontrolled rocket with no thrust bias.The author inferred from the results of the simulation that the attitude control system have better controlling effect in the range of 40～75 kilometers.
