Once Again, America Rules The World! |
(CNN) -- The National Aeronautics and Space Administration conducted a
third and final test flight of the unmanned X-43A aircraft, which uses
an experimental scramjet engine designed to push the craft to nearly
10 times the speed of sound.
A scramjet differs from conventional jet technology by not using rotor
blades to compress the air inside the engine. Instead, the scramjet,
sometimes called an "air-breathing" engine, burns hydrogen fuel in a
stream of fast-moving, compressed air created by the forward motion of
the aircraft.
Hot exhaust shooting out of the back of the jet propels it forward at
high speed.
At a post-flight news conference Tuesday, mission managers said they
had only begun to look at the data, but they believed the aircraft
reached a speed of about 6,600 miles (10,621 kilometers) per hour, or
about Mach 10.
The flight took place over the Pacific Ocean off the coast of Southern
California, in restricted U.S. Naval airspace.
The black X-43A, fastened to a larger, white booster rocket, was
carried to 40,000 feet (13,157 meters) strapped to the right wing of a
B-52, which took off from NASA's Dryden Flight Research Center in
Edwards, California.
The B-52 released the booster rocket, which dropped for several
seconds with the X-43A attached to its nose, then ignited and ascended
to 110,000 feet (36,184 meters). At that point, the scramjet engine
fired and the booster rocket dropped away.
As planned, the test flight lasted only a couple of minutes and ended
when the aircraft ran out of fuel. It eventually crashed harmlessly
into the ocean.
The test flight was originally scheduled for Monday, but technical
glitches forced NASA to postpone it for 24 hours.
Tuesday's flight was the last of three test flights in NASA's
eight-year, $230 million Hyper-X program, designed to help develop a
new generation of spacecraft that could fly into low Earth orbit at a
fraction of the current cost.
Some engineers have even speculated that scramjets could one day power
a fleet of hypersonic airplanes, capable of crossing a continent in
less than an hour. The technology also has military applications, with
the potential for new innovations in ballistic missiles.
Scramjet technology could eliminate the need to use heavy liquid
oxygen to launch spacecraft and rockets into orbit. A speed of Mach
25, or 17,000 miles (27,200 kilometers) per hour, is needed to lift a
craft into orbit.
In 2001, the X-43A's maiden flight ended unsuccessfully after an
onboard booster rocket misfired and flight controllers had to destroy
the aircraft. But last March, its second flight was successful,
reaching almost Mach 7.
However, with NASA now dedicating the bulk of its resources to
returning the space shuttle fleet to flight, completing construction
of the international space station and developing technology for
manned missions to the Moon and Mars, no additional scramjet flights
are on the drawing board.

Why can't we use hydrogen for fuel? It's in water for Christ Jesus' sake....!

Hydrogen to replace fossil fuels. And a solid state chip to replace the

Why can't we use hydrogen for fuel?
Because it isn't econonomical. You can't drill a Hydrogen well you
know. Hydrogen has to be manufactured from something else. Oil on the
other hand can just be pulled out of the ground. Hydrogen will always be
more expensive than fossil fuels.
It's in water for Christ Jesus' sake....!
Yeah, and getting it out of water takes a lot of energy, too much in
fact. It takes so much energy to make Hydrogen from water that nobody
does it that way. All hydrogen produced in industry comes from fossil
fuels. That's the problem with Hydrogen. It takes more energy to make it
than you get back by burning it. Using Hydrogen is actually more
inefficient and more polluting than using oil. People get all excited
about the clean exhaust coming out the tailpipe of a Hydrogen powered
car, but ignore the fact that manufacturing the Hydrogen is a dirty,
wasteful, inefficient, polluting and expensive process. The exhaust
coming out of the Hydrogen manufacturing plant more than makes up for
the lack of pollution at the car's tailpipe.
NASAhole used it for their scamjet?
They used it because nobody knows how to make anything other than
Hydrogen burn in a hypersonic engine. They barely know how to make a
simple molecule like Hydrogen work. It will be a while before they
design engines that work with more complex molecules.
So we can use it our scrammobiles.
Then we wouldn't be living totally off of dead things.
Wrong. All the hydrogen produced in industry comes from fossil fuels.
Hydrogen to replace fossil fuels.
It'll never happen. When the fossil fuels are gone, we won't be able
to economically make Hydrogen in any meaningful quantity.
And a solid state chip to replace the
hard drive. No spinning rotors in a scramjet,
Scramjets only work at hypersonic speeds. Below that you still need a
spinning rotor to drive a compressor.
and no spinning disk in a
'transcapicitor'.
WTF is a transcapicitor?

At a post-flight news conference Tuesday, mission managers said they
had only begun to look at the data, but they believed the aircraft
reached a speed of about 6,600 miles (10,621 kilometers) per hour, or
about Mach 10.
The flight took place over the Pacific Ocean off the coast of Southern
California, in restricted U.S. Naval airspace.
The black X-43A, fastened to a larger, white booster rocket, was
carried to 40,000 feet (13,157 meters) strapped to the right wing of a
B-52, which took off from NASA's Dryden Flight Research Center in
Edwards, California.
The B-52 released the booster rocket, which dropped for several
seconds with the X-43A attached to its nose, then ignited and ascended
to 110,000 feet (36,184 meters). At that point, the scramjet engine
fired and the booster rocket dropped away.
As planned, the test flight lasted only a couple of minutes and ended
when the aircraft ran out of fuel. It eventually crashed harmlessly
into the ocean.
The test flight was originally scheduled for Monday, but technical
glitches forced NASA to postpone it for 24 hours.
Tuesday's flight was the last of three test flights in NASA's
eight-year, $230 million Hyper-X program, designed to help develop a
new generation of spacecraft that could fly into low Earth orbit at a
fraction of the current cost.
Some engineers have even speculated that scramjets could one day power
a fleet of hypersonic airplanes, capable of crossing a continent in
less than an hour. The technology also has military applications, with
the potential for new innovations in ballistic missiles.
Scramjet technology could eliminate the need to use heavy liquid
oxygen to launch spacecraft and rockets into orbit. A speed of Mach
25, or 17,000 miles (27,200 kilometers) per hour, is needed to lift a
craft into orbit.
In 2001, the X-43A's maiden flight ended unsuccessfully after an
onboard booster rocket misfired and flight controllers had to destroy
the aircraft. But last March, its second flight was successful,
reaching almost Mach 7.
However, with NASA now dedicating the bulk of its resources to
returning the space shuttle fleet to flight, completing construction
of the international space station and developing technology for
manned missions to the Moon and Mars, no additional scramjet flights
are on the drawing board.
