B2s are cost more than their weight in gold is worth."stealth
technology"
mostly consists of advanced avionics that manage control surfaces and
flaps
that allow it to fly.
the reason the original flying wings were scraped was because they were
very
unstable and they didn't have the computers to fix that.




You are SO ignorant you don't know the difference between stealth and
fly-by-wire. Stealth means low observability, including radar and visual.
What you're talking about is the inherent instability of many of today's
best fighter aircraft; without fly-by-wire, they would not be able to do
the
maneuvers you see FA-18s, F-22s, and various Russian MIGs and Sukhois do.

Next time, try getting your act together before you show people how
stupid
you are.

no you are a fool.
the special "stealth technonolgy" that made the B-2 flyable and which is
what makes it flyable is the fly by wire avionics{mass computers}
without that then the plne would have been as useless as old B-49.

when they tallk about the high cost of the "strealth technology" it that
is what they mean.

it's easy to see why we are in such a mess, you wingnuts are as soft as a
sneaker full of ****.



Both of you are a little bit right. The so called "stealth technology"
consists aof special radar absorbing material, special radar absorbing paint
and the arrangement of the surfaces in a way that they reflect as less as
possible electromagnetic waves in the direction where the came from. These
are the main drivers. Now, the arrangemnet of the surfaces is less
aerodynamic than on conventional aircraft. Thus the flight control software
is a lot more complicated. Therefore the whole thing is very expensive.

...and no ....I am not a native englisch speaker.....but I like the

BF109...:-)

I guess you two hotshots need to rewrite the Wikipedia entries for stealth
then:
http://en.wikipedia.org/wiki/Stealth_technology
http://en.wikipedia.org/wiki/Stealth_aircraft

Not to mention:
http://science.howstuffworks.com/question69.htm

Note that NOWHERE do these mention "advanced avionics that manage control
surfaces and flaps that allow it to fly." as Ray so stupidly points out.

STEALTH IS STRICTLY ABOUT OBSERVABILITY, NOT HOW THE FLIGHT CONTROLS ARE
ACTIVATED. A lot of modern jet aircraft will not fly if all the flight
computers crap out; the pilot makes input to the joystick, and the computers
use that input, plus sensor data to determine what the plane's actually
doing, to determine what the pilot wants the plane to do. The computers then
make it happen.

Additionally, many of today's aircraft are inherently unstable. Even if
there were cables linking the flight controls to the control surfaces, a
pilot couldn't keep the plane flying as they are aerodynamically unstable.

This is why fly-by-wire is so important today.

There's one more important ingredient to the B2 'stealth technology'
and that's the radar system. It must be jam proof and virtually
undetectable. Took a lot of effort and money to get there.

Notice everyone talks about the reasons about the B2's low profile,
but no one talks about the B2 radar.

Another ingredient is the active ECM. This helps mask and spoof any
radar which may pick up the B2. It has a considerable affect on
reducing the B2 profile.
Again very costly and not talked about much.

Your an Idiot!!! Stealth is low radar cross section not fly by wire and
avionics It is the shape of the airframe and the paints and materials.
The fly by wire and computers are necessary due to the instability of
the stealth design.

Agreed but when a billion dollar plane turns into a pile of polymer due to
"moisture in a sensor" then you have to question how much redundancy is in
the system and the veracity of the design. Theyre saying a single point
failure lead to a complete and catastrophic failure of the fly by wire
system ???? I was listening to a doco and they were pointing out that the B2
has major components from every state and that this was done intentionally
to "sign" on the members for each state.

Wow, I'm very surprised to see that there was that much of the aircraft
intact after the crash. I would have expected to see pieces the size of
small suitcases, and an engine or wheel here and there.
