This research paper investigates the performance characteristics and material considerations of a bell-shaped nozzle designed for high-speed aerospace applications. The nozzle operates under specific conditions, including a stagnation temperature of 1000 K, stagnation pressure of 505 kPa, and a pressure ratio of 0.0939. The bell nozzle geometry features a throat diameter of 1 cm, exit diameter of 2 cm, convergent length of 2 cm, and divergent length of 6 cm, with an average divergent angle of 15 degrees. The study evaluates the nozzle's performance at an altitude of 48,000 feet and a flight speed of 3900 meters per second. The temperature distributions, Mach number effects, pressure ratios, and material properties for different sections of the nozzle are analyzed to optimize its structural integrity and efficiency.
