Comparative analysis of two option of separating engine of precision guided rocket

Range and separating stability is comparing and analyzing in connection with two plan of separating engine of precision guided rocket. The mathematic model of boost phase and free flight phase is built, and the simulation model is design by MATLAB/Simulink. The trajectory is simulated, and the range is obtained when the angle of fire and the separation speed. The result says that the range scope option one is larger than option two, but the two options is all satisfied the range target. But the separation stability of option two is better than option one, so option two is fit to precision guided rocket.
