Regression rate end-burning hybrid rocket motor doped with high entropy metallic additives

Hybrid Rocket Motor (HRM) has a critical weakness that impacts performance because of low regression rate. Due to this, extensive investigation has been done on the end-burning hybrid rocket (EBHR) to enhance the regression rate. Analytical studies were conducted on the EBHR to model the internal ba...
