the black box in an airplane does not get damaged. so y the whole plane is not made with that stuff?

Answer 1

If plane indestructible, it not be any thrill to fly.
Some crazy people like to take risks.
Me think if God want me to fly him give me wings.

BAAHHH, me stay on ground where belong.

Answer 2

The flight data recorder (or black box) is damaged in an airplane crash, but it's designed to be intact enough to retrieve useful information.

Black boxes are encased in titanium and stainless steel, but it's doubtful that these materials would save an airplane in a crash. Remember that an airplane is mostly filled with air (or fuel), so metal strength matters little in extreme forces like those generated by an airplane crash. Aluminum offers some key advantages, such as being lightweight, strong, and easy to work, which is why it is the metal of choice.

How do black boxes survive airplane crashes, then? Their designers pulled a few tricks, like locating them in the rear of the plane.

Answer 3

Low fuel efficiency.
Too heavy.
Very expensive.

Oh come-on.If something is good,then some way has to be found to do it.

What you have thought is actually good.

Let us try to analyse it.
What purpose will building such an aircraft serve?

The Black-box (which is actually painted Yellow or Orange,so that it may be easily spotted in a forest) contains live recordings,of the conversations happening in the coc*-pit.
It protects the recordings,from external explosions.If a bomb were placed inside the Black-box it would still be undamaged,but the recordings will be destroyed.

In the same way if the aircraft were made of the same material,the passengers will be protected from explosions outside the aircraft.If the explosion happens from inside,then the aircraft will still be undamaged,but the passengers will still be affected.
Therefore it is not built that way.

However,we may improve on your idea.

IMAGINE.
An aircraft with detachable cabins,made of Titanium and Steel.
If an explosion happens the cabins,immediately and automatically,detach from the main frame of the aircraft and goes into parachute / glider mode.
All the cabins are steered to one safe place either through auto pilot or remote control from the nearest control tower.

Now that is technological advancement.
We might see such things and much more,even in our times.

Let us all contribute,in our own small ways,to a fantastic future.

Answer 4

How about:

1. It is built of stronger and heavier materials. It would weigh so much it would be too heavy to fly. Or to fly efficiently and economically. Or if lighter but still strong materials were chosen, see item 2.

2. it would be too expensive to build, let alone fly.

3. A black box needs to secure its contents against heavy impact and fire. So there are likely either very very small or no physical openings, but rather electrical contacts only to allow electrical signals (monitoring data) to pass from outside the box to inside the box. will be very small and very restrictive in what can pass.

If you use apply that design criterion to an airplane, you will not be able to load passengers, crew or baggage. Or fuel.

Answer 5

The material the black box is constructed of is a major property however it's size also contributes.
An airplane regardless of the material is much to large to withstand the stress of a potential 500 mph impact with the ground and insueing explosion.

Answer 6

This has already been asked and answered here. It would make the plane too heavy and expensive.

Answer 7

Then they wouldn't be called planes, rather, they'd be called spaceship, cos its a miracle that they can even fly haha..
heavy + expensive

Answer 8

because it's expensive and complected system , so most of aircraft not use it .
but according to FAR (federal aviation regulation) all the civilian airplane must have it.

Answer 9

Oh look, someone else who thinks they have an original idea! Go read a physics book.

Answer 10

if it will be made up of same material then it will be so heavy that it can't fly and if somehow you will be able to fly it with help of rockets then it's ticket charges will be so high that no one will buy them
