A stepped nozzle is a type of nozzle used in fluid dynamics, particularly in rocket propulsion and jet engines. It features a design characterized by distinct sections or "steps" that change the cross-sectional area of the exhaust flow, usually in a staged or incremental manner. This design can enhance performance by optimizing the expansion of the exhaust gases through various pressure and temperature conditions.
