The hybrid rocket works by injecting liquid oxidizer into a combustion chamber with solid fuel inside. As the combustion chamber ignites, pyrolysis will occur at the solid fuel surface. These small fuel particles will mix and react with the oxidizer. The biggest advantage of the hybrid rocket system is that the fuel is in the solid state at room temperature, which makes it easy and safe to store. Even if the container or the combustor is damaged, the fuel in this system will not explode. In the technical report of AMROC, the TNT equivalent of hybrid rocket engine is 0. This is a safe, reliable and affordable rocket engine. Furthermore, if the propellant chosen only consist of hydrogen, carbon, nitrogen and oxygen atoms, the combustion products will only be nitrogen, water and carbon dioxide. This is relatively environmental friendly.

It’s almost a century since the first modern rockets were launched. Since then, many countries such as the USA, Japan, India, Russia, China, and others have launched numerous rockets, sending payloads into space. Though these rockets vary drastically in external design, they are all fundamentally big metal tanks propelled by rocket engines. So what makes a good rocket engine? We have an answer for you.
