Abstract

Combined with solid propellant rocket motor design theory and engineering practice, numerical calculation method and programming were used, the impulse weight ratio was set as the objective function, a nozzle optimal divergence ratio optimization algorithm was proposed. The result shows that the algorithm is reasonable and feasible, which improves the solid rocket design method.

Key words： solid propellant rocket engine; divergence ratio; optimization algorithm
