I found this article by accident on NASA's Science News Website http://science.nasa.gov/science-news/science-at-nasa/2001/ast01mar_1/. Although it's quite old now (March 2001) I noticed a few things mentioned that seemed quite interesting, if not a little suspicious (?). As-in things that could possibly help validate Col. Corso's and Jesse and Jesse Marcel Jr's story. If that's not the case, still, one can only imagine how far they've come with these technologies in the past 9 years!

Buck Rogers, Watch Out!
NASA researchers are studying insects and birds, and using "smart" materials with uncanny properties to develop new and mindboggling aircraft designs.

"Birds are so much more maneuverable than our airplanes are today. Birds can hover, they can fly backwards and sideways. And insects -- oh forget it! -- upside down, loop-de-loop, all sorts of things." Anna McGowan, program manager for the Morphing Project at NASA's Langley Research Center

March 1, 2001 -- The "personal aircraft" that replaces the beloved automobile in people's garages may still lie in the realm of science fiction or Saturday-morning cartoons, but researchers at NASA's Langley Research Center (LaRC) are developing exotic technologies that could bring a personal "air-car" closer to reality.

And air-cars are just the beginning.

Self-healing wings that flex and react like living organisms, versatile bombers that double as agile jet fighters, and swarms of tiny unmanned aircraft are just a few of the science-fiction-like possibilities that these next-generation technologies could make feasible in the decades ahead.

At the core of this impending quantum leap in aerospace technology are "smart" materials -- substances with uncanny properties, such as the ability to bend on command, "feel" pressure, and transform from liquid to solid when placed in a magnetic field.

"This is technology that most people aren't aware even exists," said Anna McGowan, program manager for the Morphing Project at LaRC, which develops these new technologies.

The task of the Morphing Project is to envision what cutting-edge aerospace design will be like 20 years from now and begin developing the technologies to make it happen.

For example, a personal air-car needs to be compact, yet able to fly at both very low and very high speeds.

"We know that to get a 'Jetsons' vehicle, you're probably going to need a wing that can undergo a radical configuration change," McGowan said. "The kind of wing you need at very low speed and the kind of wing you need at high speeds are completely different."

Some airplanes today can already reorient their wings, such as the Navy's F-14 Tomcat and the B-1 supersonic bomber. These planes use rigid wings mounted to large, heavy pivots in the plane's body.

In contrast, Morphing Project scientists envision a wing that will unfurl on command using "shape-memory" metal alloys or other novel "smart" materials. The material of the wing itself would bend to create the new shape.

Shape-memory alloys have the unusual property of snapping back to their original shape with great force when a certain amount of heat is applied. Any shape can be "trained" into the alloy as its original shape.

Among the exotic "smart" materials being developed by the Morphing Project, shape-memory alloys are relatively ordinary.

Imagine seeing a bullet shot through a sheet of material, only to have the material instantly "heal" behind the bullet! Remember, this is not science fiction. Self-healing materials actually exist, and LaRC scientists are working to unravel their secrets.

"What we did at NASA-Langley was basically dissect that material to answer the question, 'how does it do that?'" McGowan said. "By doing so, we can actually get down to computational modeling of these materials at the molecular level."

"Once we understand the material's behavior at that level, then we can create designer 'smart' materials," she added.

LaRC is also developing customized variations of piezoelectric materials. These substances link electric voltage to motion. If you contort a piezoelectric material a voltage is generated. Conversely, if you apply a voltage, the material will contort.

Scientists can use such properties to design piezoelectric materials that function as strain sensors or as "actuators" -- devices that create small motions in machines, like the moving of wing flaps.

Above: This thin, flexible film contains a piezoelectric material that responds to the bend by producing a voltage that's detected by the electrodes seen at the bottom left of the image.

Combined with micro-electronics, these materials could lead to a radical advance in airplane design.

"When we look 20 years into the future, we see airplanes that have distributed self-assessment and repair in real time," McGowan said.

"To make this technology possible, you would need to distribute these actuators and sensors throughout the wings. That's similar to how the human body operates. We have muscles and nerves all over our bodies -- so we are aware of what's happening to our bodies and we can respond to it in a number of ways."

The resemblance to biology doesn't end there. One avenue of Morphing Project research is to examine how nature does the things that it does well. Scientists hope they can learn lessons from this tutelage to improve their own designs.

"Nature does some things that we can't even get close to doing. Birds are so much more maneuverable than our airplanes are today. Birds can hover, they can fly backwards and sideways. And insects -- oh forget it! -- upside down, loop-de-loop, all sorts of things. We can't even get close to that [yet]," McGowan said.

Called "biomimetics," this practice of learning from nature has led to the development of -- among other things -- a facsimile of bone.

Bone is very light because of its porous interior, but it's also very strong. LaRC scientists can make structures similar to bone by injecting polymer microspheres into composite shells of the desired shape, then heating the spheres to make them fuse together like tiny soap bubbles.

Above: LaRC scientists are studying nature to understand how birds and insects achieve their high degree of efficiency and maneuverability.

"If you can have the strength and lightweightness of these bone-like structures that I'm talking about, then add in nerve-like sensors and these flexible actuators, what you're going to end up with is an extremely light-weight, very strong, self-sensing, self-actuating structure."

Compare that vision to the rigid, numb, heavy structures airplanes are made of today, and you'll get a sense of the dramatic difference "smart" materials could make in aerospace design.

As with all basic science, the applications of these "smart" materials will extend to technologies outside of the aerospace industry.

"We are working very closely with two different commercialization groups funded by NASA," McGowan said, "and the outlook for this technology is on the order of millions of applications."

Hmm. Sure this tech gonna be made so only "specialized labs" will make them ... But eventually, I see era where when we will be capable of actually growing things we need. Like.. grow your aircar,or house ... grow a shelter for the night, which then just dissolves :) Extending Nature.

But first technology must be taken out of hands of power structure.

Thanks SaiCO!


But first technology must be taken out of hands of power structure.

Well some of this technology does get transferred to the general public, as long as they can put a price tag on it. But the PTB have, right now, technologies that are far far advanced to anything the general public can dream about, except for in cartoons and movies. And most of these technologies will never be revealed as long as we live under this current Eco-Political system.

But the main reason that I posted this old article is because it looks to me like she was possibly hinting at Reverse Engineering. Possibly Alien Technology? If not, then where did they find or how did they discover these metals? She sure didn't mention that!

(What Corso said about distributing this tech to private companies for Reverse Engineering?)

What do you think?
