if "black box"flight recorder is never damaged during a plane crash,y isn't the whole airplane made out of it?

Answer 1

The emergency locator beacon is designed to survive 30-50g as any impact greater than that would make survival impossible & no reason to rush. The flight recorders are stored deep inside the plane's structure, which means part of why they survive is because teh plane absorbes the impact - like crumple zones on your car. They are also made of heavy guage material that is impractical to make a plane out of. In the space station there are points on the hull about twice as think as your household aluminum foil. They build what it has to be to make it work, any less & it would fail, any more & it would fail.

Answer 2

In Black Box, the only devices that survive are the crash-survivable memory units (CSMUs) of the flight data recorders and cockpit voice recorders. Typically, the rest of the recorders' chassis and inner components are mangled. The CSMU is a large cylinder that bolts onto the flat portion of the recorder. This device is engineered to withstand extreme heat, violent crashes and tons of pressure. In older magnetic-tape recorders, the CSMU is inside a rectangular box.
Black Box is made of using three layers of materials, the CSMU in a solid-state black box insulates and protects the stack of memory boards that store the digitized information.
The materials that provide a protective shell for the memory boards, starting at the innermost and working our way outward:
Aluminum housing - There is a thin layer of aluminum around the stack of memory cards.
High-temperature insulation - This dry-silica material is 1 inch (2.54 cm) thick and provides high-temperature thermal protection. This is what keeps the memory boards safe during post-accident fires.
Stainless-steel shell- The high-temperature insulation material is contained within a stainless-steel cast shell that is about 0.25 inches (0.64 cm) thick. Titanium can be used to create this outer armor as well.
Apart from that, its location inside the cockpit, provides a unique advantage as the entire aircraft becomes a protective case/Crumple Zone for the black box.even after this , it is crushed leaving only the CSMU.
Thus, its not only the material but a combination of several techniques which makes ablack box survice the crash.With these material used to make a chassis of a aircraft will make it the heaviest paper weight ever made.Even if it takes off, in the unfortunate event of an aircrash, the chasis will take the full impact of teh crash without any provision of a crumple zone. The impact of the suddent stop from a high speed will kill the passengers even if the outer shell is intact.

Answer 3

OK, imagine this, you are flying along at 450 kts, in a solid shell of an airplane, and you hit something solid, like the ground. The G forces that the occupants would experience would be something in the order of 45 to 100Gs. You know what that would do to you? It would turn you inside out, as the Human body is not solid and you would be "Spam in a can" as Chuck Yeager put it so poetically so long ago.

Answer 4

Because its the decelaration that kills you in a crash. The plane could be made out of that same material .. but when its travelling at that kind of speed and suddenly stops (crashes) it would be like falling from a 200 floor building. Youd just get splatted inside the plane walls :)

Answer 5

i asked this question before... The best answer i got was that the material the box is made of is very heavy. Therefore it would make it impossible to make a plane take off if it was produced from the same materials.

Answer 6

The materials that the flight recorders are made out of are very hard and dense, the Aircraft would be far far too heavy. It would never leave the ground!

Answer 7

Sometimes they are damaged. High heat, and brute force can take them out too. The material that they are encased in must be unsuitable for the exterior of a plane in some way.

Answer 8

Because if the entire airplane was covered in 3 inches of solid steel, they'd never get the damn thing off the ground.

Answer 9

the material the black boxes are made of (there are two on all commercial jets) is so heavy the plane would never be able to fly

Answer 10

because they are made from the livers of a panda. This means they are to rare to use on the rest of the plane
