this is actually a hardened container

this is actually a hardened container that’s been tested and you can see

that’s been tested and you can see

that’s been tested and you can see there’s slight deformation to the

there’s slight deformation to the

there’s slight deformation to the container panel materials but that’s not

container panel materials but that’s not

container panel materials but that’s not going to affect the aircraft structure

going to affect the aircraft structure

going to affect the aircraft structure materials for this specific container

materials for this specific container

materials for this specific container it’s basically Kevlar construction but

it’s basically Kevlar construction but

it’s basically Kevlar construction but depending on the type of design you

depending on the type of design you

depending on the type of design you could use a wide variety of materials a

any any great detail on that basically

any any great detail on that basically we’re going to actually place an

we’re going to actually place an explosive charge on the other side of

explosive charge on the other side of

explosive charge on the other side of this panel detonate that explosive

this panel detonate that explosive

this panel detonate that explosive charge and then look at the structural

charge and then look at the structural

charge and then look at the structural response of this material from that the

response of this material from that the

response of this material from that the blast effect

yeah like it started at every three

yeah like it started at every three safety briefs been given Rose blocked

multiple high-speed cameras record the

multiple high-speed cameras record the blast so what you see here is a failure

blast so what you see here is a failure

blast so what you see here is a failure of the material due to shock hole

of the material due to shock hole

of the material due to shock hole failure but you can see where the

failure but you can see where the

failure but you can see where the materials kind of bent out and peddled

now you can see this material was
