SOFTWARE MODEL AND THE REALIZATION OF AUTOMATIC PARAMETER DESIGN OF A SOLID PROPELLANT ROCKET MOTOR

Mathematical model and the design process in the automatic parameter design of a solid propellant rocket motor, as well as the data transmission between parameter design and drawing generating modules are analyzed. The automatic design software involves in it some important modules such as mass prediction, choice of propellants, prediction of mass ratio, grain design, external ballistic fitting, internal ballistics, etc. Each module works with each other to complete all tasks in rocket motor design and correction from iteration calculations. Based on the sustainer motors, the parameter design software is programmed. Through the design of the sustainer motor and scheme argument using the software, it is seen that the software frees the designers from complicated work of calculation and enhances the design efficiency.
