Ferdinand Wilhelm, Markus Haag

The limitation of the test setup are the capsular of the drop-tower.

This means that you limited in space, and in weight - but within this capsular you can design what ever you can imagine.

I think you cant simulate a car - crash! - it could be possible for smaller structural parts - the drop (and catapult) is in more or less complete vacuum and your test setup is fixed inside.

if you have more questions you can contact me

regards

Brian Lee

Drop tower tests generally are onto a flat surface so offset and oblique crashes cannot be simulated.
