Graduate Research in Engineering and Technology (GRET)


Satellite technology is advancing. Satellite propulsion requires several desired rocket properties. This is necessary for 1 kg of payload. Launch vehicles no longer need rocket engines. Application includes satellite movement, orbit transfer, and probe and lander propulsion. Space travel is inventive and exciting.

Research, production, and use costs must be decreased to make space transportation systems generally available. Security shouldn't be affected. Rocket propellants must be high-performing, non-toxic, and safe. Rocket engines have other parts. Restarting and throttling are crucial. These are inaccessible to solid rocket motors. Developing a liquid rocket engine is hard and expensive, but it can be restarted and throttled.

It's being studied for use in hybrid rocket propulsion and other space applications. Space tourist vehicles, lunar and planetary landers, suborbital launch vehicles, satellite maneuvering systems, etc. are potential applications for microsatellites (including orbit transfer). More of these applications are pending approval. Hybrid propulsion is straightforward, safe, and permits regenerative braking, throttling, and restarting. Hybrid propellants are mostly non-toxic and storable. Separate oxidizer and fuel storage enhance safety. This study examines the history, development, current applications, and future of hybrid rocket propulsion. We'll discuss popular fuels and oxidizers. Explains hybrid rocket motor's low regression rate. The article includes the author research.
