why if the black box in an airoplane is indestructuble with the metal its made of why isnt the plane...?

Question

made out of the same stuff so that is not indestructable?
i hope you understood wot i mean...

Answer 1

1. It would way a lot.
2. It would cost like 555 million U.S. dollars a plane.

Answer 2

A plane built to black box standards would be so heavy you'd have to drive it rather than fly.

Unlike the rest of the aircraft, which is mostly made of light materials such as aluminum and plastic, the cockpit voice recorder and the flight data recorder are encased in stainless steel boxes roughly 10 inches by 10 inches by 5. The steel is maybe a quarter inch thick and the boxes are so heavy in consequence that the designers don't even bother enclosing the accompanying electronics, which in a crash generally meet the same fate as the passengers. As an added precaution, the boxes are lined with a liquid-filled foam bladder encased in plastic that's supposed to protect against the intense heat of a post-crash fire.

Over the years these precautions have proven pretty effective. Investigators got useful data off one recorder that had been immersed in the ocean for seven years. But in another crash in Thailand the recorder landed in a pool of flaming fuel and basically got cooked.

One thing the NTSB learned from experience: be careful where you put these things. Recorders used to be located near the point where the wings joined the fuselage, the theory being that this was the most heavily constructed part of the plane. Problem was, being heavily constructed, the parts of the plane falling on the recorders often crushed them. Now the recorders are put in the tail section so that, assuming your typical crashing plane goes in nose first, the forward part of the airframe absorbs most of the impact.

Sitting back there won't help you, though. When you mix stuff in the Cuisinart, you think it matters which end of the banana went in last?

Answer 3

Well, NO.
Black boxes (often painted in high-visibility bright orange or red) are made out of very strong metal, like steel, and is very thick. If the aircraft was made out of this, It would not make it into the air. Even if an aircraft like this was made, passeners would get killed anyways.
So lets say that this plane DID make it into the air. If it crashed, it would kill all passengers all together. Just like bostonan said, the seatbelts would act like cheese slicers. You would get sliced at your waist, and then your lower and upper body parts would fly forward with everyone else's and get turned into pure mush. Put a live rat in a blender and the result will be similar to that of the mush after the remains of the body were smashed forward. Also, having an aircraft of this weight and mass and strength, that would require VERY powerful engines to fly. POWERFUL engines typically mean more fuel is used.
Today's aircraft are generally made with aluminum, some steel, titanium, composites, and plastic.
Black boxes are not indestructable. NOTHING is indestructable.
Of course, you would probably make your arms fall off if you tried to take a sledge hammer and breaking the box.
Also, please use the search function. This question has been asked quite a bit. It is almost coming to the point like the other person answered: If jet fuel is flammable, why not use water?

Hope this helps.

Answer 4

It's not indestructable. It's protected mainly by the crushable cabin of the aircraft. Only the data recorder mechanism is hardened. If you built an aircraft to those standards, it would never leave the ground. Imagine an M1A Abrams tank with 3 foot wings.

Even if you had some magic material that was totally indestructible and light enough, the passengers would still all be killed. When the aircraft crashed, it would come to an instant stop but the passengers would keep moving at 500 MPH. They'd but cut in half by the seatbelts which would act like cheese slicers. The body parts would then be smashed into the seat or bulkhead in front of them and all of the guts and goo would spray all over the inside of the aircraft. Nice visual, eh?

Answer 5

it's not really the strength of the metal, the metal in a black box isn't that much tougher than the metal in the rest of the plane. it stays intact because it's at the tail so the plane absorbs some of the impact like a giant crumple zone. plus as it's in a small box they can reinforce the interior to stop the box from being destroyed. if they reinforced a plane in the same way it wouldn't take off and you wouldn't get any seats in it.

Answer 6

Simple put; the size of the box is small and so the Cost of making such a box is a lot less as it is a special metal. Imagine if the whole plane is made out of this metal??? The cost a plane ticket would definitely reach for the skies and there would be no such thing as Budget Airlines anymore.

Answer 7

Another reason, the black box is designed to undergo a huge stress (the crash) only once. Aircraft have the repeated stress of taking off, flying, landing, etc. So it wouldn't be any better anyways.

The 737 was tested to double the most extreme forces it would encounter in flight before it was certified, yet one lost its roof after its 89,090th flight.

It is mostly the location of the FDR that makes in survive a crash (in the tail), and then not always

Answer 8

can you imagine the expence of making a plane of the same materials , obvioulsy this would contrst back on how much it would cost to have a flight in such a plane .not to mention the aeronautical factors of weight , size and lift .would it even be able to get off the ground .so unless you design a plane forget the answer to this one it would mean longer run ways also for such a weight to be able to fly not to mention the over all weight of being fully loaded with people and luggage hummmmmmm some what of a white elephant id say or they would have made them long ago dont you think .

Answer 9

The materials used to construct the in-flight recorder (black box) are very heavy and the methods used are extremely expensive. If an entire aircraft was made from this material, you would need countless more engines and fuel to get it airbourne and it would be extremely difficult to control. The landings would need to be on reinforced runways too. It's just not practical.

Answer 10

its not only weight but even thought the structure is like that, it will still be damaged. If you drop a car from a building and a HotWheels at the same time which do you think will be destroyed?? the car right exactly, and hotwheels are made of alumminum and a car is stell and many mixes of metals

Answer 11

Weight. And the strongest metal in the world cannot compensate for the incredible g-forces involved in a high speed collision. That should be the focus of further safety engineering. Remember: "It's not the fall that kills you. It's the sudden stop."
