Small sugar-propellant rocket motors, often called R-Candy motors, provide an accessible platform for studying propulsion and nozzle design. Their relatively simple construction makes them suitable for educational and experimental rocketry, but predicting how combustion pressure, temperature, and exhaust flow interact inside a small motor can still require considerable trial and error. In particular, the nozzle must accelerate the combustion gases while maintaining stable chamber pressure, manageable thermal loads, and consistent thrust.
