Projectiles used in this test series were primarily aluminum spheres, ranging from 0.2 mm to 1.0 mm in diameter, plus some nylon, sapphire, and steel spheres. Impact angles ranged from normal (which we define as a 0° impact angle) up to 60°. Impact velocities were from less than 4 km/s up to approximately 7 km/s.

Projectile sizes (Al) required to cause target failure (at the velocites defined above) were between 0.5 and 0.6 mm for Basic Suit samples, approximately 0.3 mm for Glove Finger samples, and between 0.8 mm and 1.0 mm (for 0° impacts) on Glove Gauntlet samples.


Each type of EMU target was supplied as a panel 10.4 cm (4") square,
made up of several thin layers of material.
