Investigation of regression rate end-burning typed hybrid rocket motor
Hybrid Rocket Motor (HRM) has a critical weakness that impacts performance: low regression rate. Due to this, extensive investigation has been done on end-burning type HRM to enhance the regression rate. Experimental works were conducted on the end-burning HRM compared to the conventional HRM. The p...
