Variable Area Nozzle Design for Varying Atmospheric Conditions of Jet Engines

The principle of variable area nozzles (VANs) and how they can adjust to shifting air conditions to maximize engine performance is investigated in this study. A 3D-printed model nozzle with movable throat and exit regions is powered by electromechanical actuators. A wind tunnel is used to test the nozzle's performance in flight-like conditions. The experiment highlights the numerous ways in which variable nozzle geometry can maximize thrust production, lower drag, and boost fuel economy. To detect vital characteristics like temperature and pressure, sensors are used. By providing insights into their use in military and commercial jet engines, the initiative emphasizes the importance of VANs in advanced propulsion systems. The outcomes show how performance can be improved at various altitudes and flight speeds with flexible nozzle designs.
