Abstract: The present work is done to protect defence people platform against IR guided missile threats, by essentially cooling the funnel surfaces, such that temperature between background and platform becomes minimum. The multiring eductor/diffuser type IRSS device uses ejector action to draw in large volume of ambient air for both metal gases cooling. With the ejector action, the exhaust gases are accelerated in convergent nozzle and the resulting high velocity jet is used to entrain ambient air within a mixture. Entrainment for ambient air quantity depends on the level of cooling required for hot gas temperature to about 80% to 125% of hot gases. |
Keywords and phrases: diffuser hot temperature cooled, ambient temperature at the exhaust, prevention from the enemies in naval applications, a thermodynamic research.
