Rocket engine design requires balancing combustion chamber conditions with nozzle geometry to maximize specific impulse — the measure of propellant efficiency. This simulator models the thermodynamic expansion of combustion gases through a converging-diverging nozzle, showing how pressure, temperature, and velocity evolve from chamber to exit plane. Changing the area ratio or chamber pressure directly updates thrust and Isp.
