Is it true that air plane black boxes or what ever its called can on be destroyed be 10000 pounds of pressure

Question

i fell like asking

Answer 1

The cockpit voice and flight data recorders are not indestructable by any sense of the word. It would take a lot less than 10000lbs to destroy one. The only thing they are designed to protect is a small module inside that stores the data, and that can take a lot of shock and a fire if it doesn't get too hot and doesn't burn too long, but it can be crushed by less than 10000lbs.

I just went out into the shop and I can bend the outer case of one in one hand. The frame is strong but not unbreakable, and the other components are very fragile. I could snap one of the curcuit cards in my hands.

Answer 2

The boxes are made of steel. The criterion of concern is not pressure, but stress, which uses the same units - i.e. psi, or lbf / in^2. Most stainless steels start to deform permanently (yield) at about 32,000 psi. If they are heat treated, they may not yield until they reach over 100,000 psi. Actual failure occurs at even higher levels. Some steels are capable of withstanding stresses exceeding 200,000 psi without failure, although they may look pretty nasty afterward.

Answer 3

mmmm,i think its 50000 of  pressure,did you know they were bright orange?

Answer 4

10000 PSI? Yes it would, there wouldn't be anything left of the plane either. But it wouldn't experience that sort of pressure anywere a plane would be... I'm pretty sure 10000PSI is higher then Soviet Venus Probes were build to stand...

Answer 5

Anything that man can make can be destroyed. The Flight recorders are designed to withstand the forces generated in any imaginable crash and accept some damage but remain readable. If for example the aircraft fell into an active volcano the recorder would probably survive for a while but be destroyed before anyone could go in to recover it

Answer 6

Generally speaking, no, but if that pressure was exerted by a point on a small area it might be able to penetrate.

Answer 7

They are not so much designed to withstand pressure, but shock due to high G loads.

I have recovered them from aircraft looking totally trashed but the contents are still usable.

Answer 8

i am no expert but i very much doubt it

Answer 9

i dont realy know but they are placed in the tail as it is the safest place for it to be and its orange in colour
