u know that BLACK BOX in planes that can neva be destroyed.. y is the whole plane not made up of that material

Answer 1

·First the cost would be too much.
·Second the airplane wouldn't fly, it would be too heavy to get off the ground.
·Third the Black Boxes aren't black, they are orange, and they aren't indestructible, the NTSB has to salvage them often. They aren't even water tight, but since they use a steel tape it will survive immersion.

You reach the point of dimensioning returns, with the stronger you build a plane, the more weight you put on it, which requires larger engines, which will require more fuel, which will require more storage space, which will require a stronger airplane…

A plane has to be built as light as possible for it to fly. Aluminum has come into use in the aircraft industry because for the weight it is a very strong material that is also why it is popular in the automobile industry. My dad worked for Boeing and said that the girder design had to have lightening holes in it. Of course anyone who heard that would think of a lightning strike. The holes are required to make it lighter, and because of a quirk in statics and dynamics of the girder the strength of that girder is NOT reduced by the holes in it.

I watched the movie The Guardian tonight and they stated that a fall from as little as 50' is like hitting concrete when you hit the water. So how do you design something that can fall from 20,000 feet at 200 mph, so it won’t break up on impact? If you built it out of solid iron or even one solid diamond then the passengers would still die because of the shock of impact.

Airplanes are designed to be as safe as possible and they are the safest way to travel. Most airline accidents only happen on takeoff and landing, but still you are flying a multi-ton vehicle with a heavy live load (the people) that is coming in at a high rate of speed. If that craft has an accident then people will die. That is unavoidable.

Airplanes have a glide path of less than 9 degrees when they come in to land. The space shuttle has a glide path of 45 degrees; another words it flies like a brick. Still they have to come in with empty onboard fuel tanks and the solid quartz windows had to be shaved to save weight. If you want it to fly then there is only so much structure it can carry. The same is true with cars, trains, motorcycles etc. They can all be made safer, but past a certain point they won’t work anymore because the weight of the structure is too great.

What you are proposing would be like trying to build cars with a foot of solid granite rock on each side. The car would move, but not more than 5 miles per hour. You certainly couldn't put it on the highway, and a plane designed like that wouldn't ever fly (Okay, the iron plane would be a little lighter, but it still wouldn’t fly.)

Answer 2

A black box is really not black since its painted orange in color for easy visibility. Also there is not 1 black box in an aircraft, there are several (upto 130 in most cases). Technically, in an air incident, the two 'blackboxes' (cockpit voice recorder & cockpit data recorder) are retrieved first since they contain data that gives an overview of the entire flight. Other blackboxes located in others parts of the aircraft contain detailed data about specific parts of the craft.

Blackboxes are made of very high strength steel that can resist severe forces, but are destroyed in many crashes nevertheless.

In aircraft design, you are always fighting weight. So aircraft manufacturers use aluminum and titanium alloys which are stronger than steel yet lighter than steel. If totally re-inforced (like Air Force One), the craft would require way too much power and guzzle fuel so much that the flight would be commercially unfeasible.

Answer 3

To begin with, the cost would be prohibitive!.It is also a problem of the compact nature of the Black Box which is not possible with a large body aircraft. Hope some day your idea finds takers in the design groups.

Answer 4

it couldn't get off the ground. and it can be destroyed in some cases . why do they call it a black box when it's red ? and why don't they have parachute's inbeded in the top of the plane from front to back so if the plane is going to crash it could deploy them and slow the plane down so it hits softer and save some lives

Answer 5

Too heavy and too costly. As it is the planes cost millions of $ for each plane. Think of the cost of flying a plane that is too heavy and built at an astronomical cost. Economics would not permit for such a venture.

Answer 6

The plane would be far too heavy to ever get off the ground. By the way, bad form on originality.

Answer 7

Actually, its NOT a Black Box, its a bright Orange and the reason the WHOLE plane isn't made of it is cuz its too dense; as you are, obviously!

Answer 8

unfortunately the black box is made of 1/4 inch thick stainless steel...the plane would be too heavy to fly if it were made of that...fortunately there are new materials available that are strong and light such as carbon fiber and titanium...these are very useful for this circumstance but very costly...maybe in the future the cost of such materials will drop and we will be able to use them for such usefull purposes =)

Answer 9

i was just thinkin about this famous question last night, but i was thinking what the hell the black box was used for and why dosent it get destroyed.

Answer 10

It would be a nice idea, too bad someone from Y!A hasn't decided to build one yet.
