Conventional propulsion systems mostly based on the propellants which are highly toxic in nature. In a single rocket, the amount of such propellant is generally hundreds of tons. When this huge amount of propellant burnt, it develops a large amount of unburnt particles as well as gases which damage the ecosystem. This paper is based on the project in which Hybrid Rocket was developed and Paraffin wax was tested as propellant. Paraffin was selected because its regression rate is higher when we compare it with other conventional Hybrid Rocket fuels. It is also safe to handle and better for the environment. As oxidizer Nitrous Oxide was used due to its low toxicity and self-pressurizing property which eliminates the requirement of additional gas pressurizing system. The by-product of Paraffin wax is water vapour and carbon dioxide. If a rocket fuel is eco-friendly, then it can be used frequently and in a large amount.

Apart from my efforts, the success of this project is largely depended on the encouragement and guidance of many others. I express my thanks to my parents because since starting they support me when firstly I share my idea of doing project in this area, and they encouraged me whenever I lost my hope. I also thank to my near and dear ones for their encouragement.
