Cover Story: Solid-propellant rockets are used for many applications, including military technology, scientific research, entertainment, and aerospace education. This study explores a novel method for design modularization of rocket airframes, utilizing additive manufacturing. This method replaces part subsystems with complex multi-function parts to improve customization, design flexibility, performance, and reliability. To verify the value of this method in the design of rocket airframes, computational and experimental techniques were used to test a set of generated designs. The methods and the study results were examined in detail for sources of error, which would then be addressed on subsequent iterations of the design. View Paper here
