Automatic approach for 3-D grain burning area design of solid rocket motor

An improved automatic approach for 3-D grain burning area design of solid rocket motor was developed. According to the input data of the design indexes and the whole variables, the approach could automatically determine a number of probable projects of grain construction, optimize the grain configuration geometry for every project, select the preferred projects, and obtain the final grain burning area design results. The approach was utilized in 3-D grain burning area design of some experimental motors. The results show that this approach is practical and effective.
