WebA kinetic energy penetrator ( KEP ), also known as long-rod penetrator ( LRP ), is a type of ammunition designed to penetrate vehicle armour using a flechette -like, high- sectional density projectile. Like a bullet or kinetic energy weapon, this type of ammunition does not contain explosive payloads and uses purely kinetic energy to penetrate ... WebJan 3, 2024 · During the starting-jet stage, the flow rate is a function of time; three temporal profiles of the exit velocity (pulsation, sinusoidal and real-cough) were investigated in this study, and our results showed that the cough flow’s maximum penetration distance was in the range of a 50.6–85.5 opening diameter (D) under our experimental conditions.
