Swirl Injection Effects on Hybrid Rocket Motors
Journal of Aerospace Technology and Management, 2015 In the last decades, hybrid rocket engines have been increasingly studied and used in space vehicles. However, the low regression rates and specific impulses still represent major drawbacks to this technology. The objective of this study was to quantify
