In the show, Aura for the most part seems to act as a buffer. Jaune for example had a bruise from when Cardin was beating him up in the forest, but his Aura should have blocked all the damage if it acted as a shield. Bladed weapons on the other hand are much sharper and could probably cut right past Aura if enough force was used. As far as Penny vs the WF, they probably had some armor under their clothes and the blades Penny used may have just knocked them out instead of killing them. As far as the planes go, I'm just imagining some poor guy standing right in the middle of the plane as Penny attacked.
