Rocket Nozzles
Rocket nozzles are the final component of a rocket engine's exhaust system. They are designed to expand and accelerate the high-temperature, high-pressure gases produced by the combustion of propellants, converting thermal energy into kinetic energy. The shape of the nozzle is critical to the engine's performance, as it determines the exhaust velocity and thrust. Nozzles can be either convergent, divergent, or a combination of both, depending on the type of engine and the altitude at which it will operate. Convergent nozzles are used for subsonic exhaust velocities, while divergent nozzles are used for supersonic exhaust velocities. The optimal nozzle shape for a given engine is determined through extensive testing and computer simulations.
