convergent-divergent duct — A duct that has a decreasing cross section in the direction of fluid flow is convergent, until a minimum area is reached. Thereafter, the cross section increases, or becomes divergent. Relationship of pressure, temperature, and velocity in a… … Aviation dictionary
convergent-divergent exhaust duct — An exhaust duct used in supersonic aircraft. The cross sectional area of the duct decreases in the direction of the airflow until it is so small that the gas flow becomes supersonic. Thereafter, the duct enlarges so the gases further speed up… … Aviation dictionary
convergent-divergent inlet — A supersonic inlet duct. The forward section is convergent to increase pressure and reduce air velocity to a subsonic speed. The aft section is divergent to further increase air pressure and slow airflow to approximately Mach 0.5 before entering… … Aviation dictionary
