Abstract :
The 90 mm EMGWS D1 projectile is an unguided projectile that is designed for launch from an electromagnetic gun to achieve significant armor penetration. The 90 mm D1 type II workhorse projectile is used to test material strength, fabrication techniques, and projectile structural integrity. The type II flight projectile is designed to allow maximum stress levels of 100 ksi when launched at 100 kg peak acceleration. The total weight of the projectile is 2.0 kg to attain a muzzle velocity of 3.0 km/s from a 9 MJ EM gun. The type II projectile configuration employs a tungsten nosetip plus 12 segmented tungsten penetrators, a two-piece aluminium discarding sabot, an aluminium pusher plate, and a nylon orbturator. The pusher plate, can incorporate either a solid or plasma armature
