2 Navy Airmen and an Object That ‘Accelerated Like Nothing I’ve Ever Seen’
#17
Analyzing the Video
As the video starts, this is what the pilots observe from inside their cockpit:
• The sensor is in “white-hot” mode—white elements in the display are warmer than the dark, or cooler, areas. The UAP appears as a white shape in the middle of the screen.
• The chasing aircraft is in a left-hand turn flying Mach 0.58 at an altitude of 25,010 feet.
• The UAP is flying slightly below 2 degrees and 54 degrees to the left of the Super Hornet, traveling right to left.
• Looking closely, we can see a dark, or opaque field that appears to surround or encapsulate the object.
The pilots aboard the Super Hornet are not only highly capable fighter pilots, but they are trained observers skilled at scrutinizing their observations and targets in order to ascertain “friend or foe.” They are specifically trained to look for discreet changes in shape, size position, flight attitude (angles), and speed in order to determine the nature of the threat. They are able to discern nuanced details that few people would normally recognize. Paramount to their training is their ability to handle stress and maintain radio discipline. In the footage audio, they are clearly struggling to understand what they are witnessing.
At 0:03, in the first radio transmission, we hear one of the pilots state that it is “a [expletive] drone” aircraft.
At 0:06, upon further observation, a different observer calmly states, “There is a whole fleet of them. Look on the ASA (radar display).” The first observer responds with “My gosh!” It is important to note that the ATFLIR has only a single object in its display. The radar is simultaneously providing the pilots a picture of the larger air space, where they are tracking multiple targets.
At 0:11, it is noted that “They are all going against the wind. The wind is 120 knots (138 mph) out of the west.” We can see that the speed and altitude of the object is unusual for any drone-type aircraft. On that information alone, the likelihood of an entire fleet of drones capable of operating under this scenario is highly improbable and would require resources only few nations could afford.
In the midst of this exchange, the sensor is switched from “white-hot” to “black-hot.” The imaging of the object is now much clearer. It has a distinct shape: a distorted oval with small protrusions from the top and bottom. The object’s opaque aura is now also very distinct: a “cool” glow that extends about a body thickness around the entire object. There appears to be no observable flight surfaces or exhaust plume, nor any typical components usually associated with conventional aircraft.
“Look at that thing, dude.” The observer is clearly surprised at what is being seen.
At 0:24, the object makes a small, but very sharp, altitude change, possibly indicating it may be operating in a vacuum environment. Its direction and speed remain unchanged despite the continuous 120-knot headwind it is encountering.
“That’s not [unintelligible] is it?”
At 0:27, the object begins a series of distinct rotations and changes orientation by almost 100 degrees. Its orientation is now perpendicular to the horizontal plane despite the headwinds. This maneuver is executed in a manner that is inconsistent with current principles of aerodynamicsand possibly indicative of a vacuum environment. As the video concludes, the object's orientation and performance seem to defy current principals of physics to include atmospheric resistance and normal aerodynamic forces. During the orientation change, it also slows to a near stop, but does not change altitude.
One observer states, “Look at that thing!”
Another observer says, “It’s rotating.”
Implications
With the chain-of-custody documentation, GIMBAL can officially be designated as credible, authentic “evidence” of a UAP. Evidence of a flying vehicle with a shape normally associated with something out of science fiction. Currently there are no other known technologies that we can compare to what is being observed in both performance and design, which means there’s a craft that demonstrates flight characteristics unlike anything we know, understand, or can duplicate. Because we cannot duplicate these flight characteristics, we can conclude that the object is employing technologies that are more advanced than our own.
GIMBAL is just one of several official videos obtained by TTS Academy that can be interpreted as credible proof that the physics of advanced flight exists. We are also in the process of collecting additional data from both military and civilian personnel and sensors. The question now changes from “Can it be done?” to “How is it done?”  Arrow

Urzhumov also says that his theories and calculations have many potential applications outside of the ocean. Similar designs could be used to create a distributed ion propulsion system for spacecraft or to suppress plasma instabilities in prototypes for thermonuclear fusion reactors.

"I believe these ideas are going to flourish in several of these fields," said Urzhumov. "It is a very exciting time."

Electromagnetic water cloak eliminates drag and wake

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while simultaneously helping it avoid detection.


The idea originated at Duke University in 2011 when researchers outlined the general concept. By matching the acceleration of the surrounding water to an object's movement, it would theoretically be possible to greatly increase its propulsion efficiency while leaving the surrounding sea undisturbed. The theory was an extension of the group's pioneering work in metamaterials, where a material's structure, rather than its chemistry, creates desired properties.
Six years later, Yaroslav Urzhumov, adjunct assistant professor of electrical and computer engineering at Duke, has updated the theory by detailing a potential approach. But rather than using a complex system of very small pumps as originally speculated, Urzhumov is turning to electromagnetic fields and the dense concentration of charged particles found in saltwater.
The study appears online in the journal Physical Review E on December 7, 2017.
"The original idea was so big that it enticed colleagues at the Naval Undersea Warfare Center to help us pursue it, even though they were incredibly skeptical," said Urzhumov, who was among the researchers who worked on the original 2011 paper. "Since then, we have identified a path to materializing this seemingly impossible proposal."
The crux of the issue being addressed is that water is a relatively viscous liquid that, when moved, likes to pull its surroundings along for the ride through shear forces. A fish feels much heavier being pulled through the water than lifted through open air because of all the water dragged along with it.
Besides essentially pulling extra water, drag can also be increased by how water flows around an object. A hydrodynamic object with fluid flowing smoothly along its surface creates much less drag than a blocky object that creates a mess of chaotic, turbulent flows in its wake.
The solution to these issues is to move the water out of the way. By accelerating the water around the object to match its speed, shear forces and turbulent flows can both be avoided.

"There are many ways to reduce wake and drag, like surrounding an object with low-friction bubbles, which is actually done with some naval torpedoes," said Urzhumov. "But there's only so much you can do if you're just applying forces at the surface. This cloaking idea opens a new dimension to create forces around an underwater vessel or object, which is absolutely required to achieve full wake cancellation."

Urzhumov originally envisioned a sort of truss-like frame enveloping an object with thin structures and tiny pumps to accelerate its flow as it passed through. But as time went by, he decided a more practical approach would be to use "magnetohydrodynamic" forces.
When a charged particle travels through an electromagnetic field, the field creates a force on the particle. Because ocean water is chock full of ions like sodium, potassium and magnesium, there are a lot of charged particles to push. The idea isn't as crazy as it may sound—Japan built a prototype passenger ship in 1991 called the Yamato 1 using these forces as a means of propulsion, but found the approach was not more efficient than traditional propellers.
In the new paper, Urzhumov and his graduate student, Dean Culver, use fluid dynamics simulations to show how a water cloak might be achieved using this approach. By controlling the velocity and direction of the water surrounding a moving object, the simulations show such a system can match the water's movement within the cloak to that of the surrounding sea.
This would make it appear that the water inside the cloak is completely stagnant in relation to the water outside of the cloak, eliminating the drag and wake. Of course, practical implementations aren't perfect, so some drag and wake would remain in any realization of the device.
While the simulations used a cloaking shell half the width of the object itself, the calculations show the shell could theoretically be as thin as you wanted it to be. Another important result was that the forces inside the shell would not have to change directions as the object sped up, they would only need more power.
"That is one of the major achievements of this paper," said Urzhumov. "If you don't have to adjust the distribution of forces, you don't need any electronic switches or other means of dynamic control. You can set the structure with a specific configuration and simply crank up the current as the object speeds up."
Urzhumov says that for an actual ship or submarine to ever use such a device, it would need a nuclear reactor to power it, given the enormous energy requirements to cloak an object of that size. That does not mean, however, that a smaller diesel vessel could not power a smaller cloaking device to shield potentially vulnerable protrusions from detection.
Urzhumov also says that his theories and calculations have many potential applications outside of the ocean. Similar designs could be used to create a distributed ion propulsion system for spacecraft or to suppress plasma instabilities in prototypes for thermonuclear fusion reactors.
"I believe these ideas are going to flourish in several of these fields," said Urzhumov. "It is a very exciting time."
