I recently saw a tweet about Hypervelocity Impact Sample and someone ask how is it possible to shoot a projectile at that speed and what happened to the used projectile when hitting the shield.
I found that it was probably shooted by a Two Stage Light Gas Guns but I didn't found anything about the projectile.
I only found this:
They got their name because hypervelocity impact produces local pressures in the target and projectile that greatly exceed the material strength of these materials, the material behaves as if it has no strength, i.e., like a fluid, or hydrodynamic behavior
What happened to the projectile ?
Does the projectile melt with the shield ?
At this speed, does the projectile melt before hiting the shield ?
EDIT: deletion of the last question, test done in vacuum.
