WHY HYBRIDS?
Hybrid rocket engines provide a lot of advantages at the scale of our rockets. They combine the safety and efficiency of liquid propulsion systems, with the simplicity and low cost of solid motors.
Most hybrids work by passing a liquid/gaseous oxidizer over an organic fuel, creating combustion products, which are accelerated by the nozzle, creating thrust.
PROPELLANTS
Our Propellants of choice for these kinds of engines are usually liquid nitrous oxide and paraffin, due to their safety and accessibility. After having originally constructed and tested an 800 newton engine, we have decided to scale back to 350 newton and focus on reliability, efficiency, longer burn times and understanding all aspects involved thoroughly after an extensive test campaign. In hybrid rocket engines, the regression rate of many of the available fuels are often a limiting factor. This is because in order maximize fuel surface area, to reach the desired fuel mass flow, engine compactness is hindered. This is why we chose paraffin wax. This offers a high regression rate, unmatched by any other fuel with similar accessibility, while also being a relatively eco-friendly fuel.
