Stealth Bomber

[Anusha]

Does anyone know the technology behind the Stealth Bomber?
I mean, how it can go undetected?

[djvcom]

yep :yes:

GO READ THIS....I DONT HAVE TO EXPLAIN ALL THEN.....:D:D:D:D:D

Well, I know a little. They are not 100% stealth, right?

They are 100% stealth:yes: :yes: :yes:
they dont give out the whole stealth technology right....?
from what i'v heard, They use a stealth paint and the design plays a big roll in this case....:yes: :yes: :yes: mainly these two things help it to be stealth and other thing that we dont know.....:yes: :yes: :yes: :yes: ;) :D :D

Mainly the design helps. Paint, I don't know.

As I have heard, it lowers the radar's detection range to only 6km away from 600km away. I don't think 100% stealth can be achieved though.

radar is a electromagnetic wave send to air.. if it doesnt come back they take it as no object area, when a normal air craft fly over it reflects the wave back right into the detection area. cz normal aircaft does the inflexion syndicate to the wave which makes easy to find.

but the stealth crafts are build with a triangualar shape from top to the bottom so that it will send away the wave from where it came ffrom.. then it wont be detected. the paint used is for less the inflexion syndicate which maks it totally stealthy..
i wrote this down so if anyy one has qs i'l try to put some illusions too

[Anusha]

What does "inflexion syndicate" mean?

[tckrockz]

ade ela thread eka i ws gonna ask dis 2

[djvcom]

yeah inflexion syndicate?????

Anyways, as I've come to know....

Radar will hit an object and reflect (or disperse) to various directions. Only the rays that hit perpendicularly will reflect to the source, and thus will show up on the radar map as an object (in this case, a plane)

In designing the Stealth Bomber, they have reduced the number of such perpendicular planes as much as possible.

1. The edge of the wings are in an angle towards back. There are perpendicular planes, but they won't reflect in the SAME direction as the radar source.
2. The windscreens are tilted back
3. The frames of the windscreens are saw toothed (this only reduces the reflections, but not eliminate it, because there are small points at each saw tooth)
4. The back wall of the cockpit is tilted back

These things have reduced the detection range to 6km from 600km.

:yes: :yes: :yes: :yes: :yes:
but its fast and can't be seen easily in combat....

In the Iraq bombing incident, they used some other solution to penetrate the radar network. There were several layers of radars (16 iirc).

Ideally, the ranges of the radar scopes would overlap so there is no gaps for a plane to fly without being detected. Now that they have reduced the 600km range to 6km range, there are lots of gaps.

The Americans found a new technology to find the distance to the radar source, when it receives the radar. Now they know where the radar sources are.

They used a 3D map (drawn in realtime in the flight's computer screen) which showed the 6km radar hemispheres and the gaps between them. They could fly in those gaps with the aid of the map and bombard the inner most radar source.

Wonder what the Iraqis felt when this happened. They were told radar was impenetrable. True, but when there's a will, there's a way. :yes:

True. But I saw somewhere that it's so hard to fly because of the lack of aerodynamic importance.

hummmm have to read more about it then....i haven't gone in to much details....:yes: :yes: :yes:

meka full research ekak daanawa B-2 eka gana...mata hitenne SL walata ekak aran enna wage hadanne muu....:lol: :lol: :lol: :lol: :lol:

ade ela thread eka i ws gonna ask dis 2
pacha gahana epaaaa.. heheheh jk jk;):D:lol:

anywyazzz yaa interesting to read:yes:

[lodperera]

What does "inflexion syndicate" mean?
its in physics.. which means that will broaden the spreading of the wave..
ex- if a normal wave spreads over 100m after reflection.. the same wave should spread over 1000m to be named as that kind of reflect an inflection..

[pasanlaksiri]

I think they using very expencive Radar Absorbing Materials

And i think they have to replace it or do something like that after its every fly. ( If im wrong correct me :D )

This is a nice article. >> http://www-tech.mit.edu/V121/N63/Stealth.63f.html

You're the one and only terrorist here, now that the LTTE mf's are not here.

Not so clear, but got an idea :D

Hw cud i be?? :D
