摘要
Abstract
The combustion process of dual burning rate grain with series embedded metal wires was analysed and the basic law of combustion area variation was obtained.Based on the PRO/E,the complex burning area of the grain was calculated precisely.To calculate the internal ballistics for the special structure of the motor,a group of differential equation was established and solved by the Runge-Kutta method.The calculation results agree with test data very well.The calculation method of the complex internal ballis-tics is precise and reliable,which could meet the engineering requirements.关键词
