Nozzles
In space and astronautical engineering, a nozzle is a device designed to control the direction or characteristics of a fluid flow (especially gases) as it exits an enclosed chamber or pipe. Nozzles are commonly used in rocket engines to accelerate and direct the exhaust gases produced by the combustion of propellants. The shape and size of the nozzle play a critical role in determining the performance of the rocket engine, including its thrust, specific impulse, and efficiency. Nozzles can be convergent (narrowing) or divergent (widening), or a combination of both, depending on the specific application and design requirements. The design of rocket nozzles is a complex and challenging task that involves considerations of fluid dynamics, thermodynamics, materials science, and manufacturing processes.
