During the test of Protection Material it is amongst others, important that the projectile hits the material with the lowest possible YAW angle.
Only then it is guaranteed that the full kinetic energy of the projectile performs optimally.
The B581 system will be placed near the test sample.
The projectile trajectory needs to be calibrated once after each system setup by means of a reference rope.
In a dimmed room any projectile passing the active sensor area of the trigger screen activates simultaneously two spark flash lights.
The shadowgraph projections on the reflecting foils are taken by the orthogonally mounted digital cameras and transferred to the PC.
Both individual projectile angles (α and β) are evaluated automatically with reference to the calibrated trajectory.
Based on the individual projectile angle of the left and right camera the projectile YAW angle will automatically be calculated.
