“…Hybrid rockets are entitled with unique features such as simplicity, thrust modulation, safety and low cost compared to conventional liquid and solid rockets. Despite their distinct advantages, the polymeric solid fuels exhibit a low regression rate, limiting their potential as conventional hybrid fuels (Karabeyoglu et al , 2003, 2004; Karabeyoglu and Zilliac, 2006; Lee and Tsai, 2008; Sakote, 2014; Battista et al , 2019). Several researchers were found that paraffin fuel achieved promising results with various oxidizers, gaseous oxygen, liquid oxygen, hydrogen peroxide and nitrous oxide (Brown and Lydon, 2005; Karabeyoglu et al , 2004; Santos et al , 2005; Wu et al , 2018; McCormick et al , 2005).…”
