Rapid solid rocket motor design.

Internal ballistic design of solid rocket motors (SRMs) is a well-established field. Most grain designs have been well characterized throughout the industry. However, generating and evaluating different grain design options can be quite tedious and time-consuming. Thus, it was endeavored to create a preliminary design tool which can be used in a workshop with a client to promptly establish the most likely and suitable grain and performance design for the particular missile application, starting with a system definition. This tool was developed in the MATLAB environment. This tool also serves as an input for the more detailed design. As part of the larger program it was endeavored to create an internal ballistic tool that allows for more detailed analyses. It was endeavored to use the rapidly expanding open source tools available to develop a fully coupled CFD internal ballistic tool. The grain regression and CFD modules have been developed to date.
