Developments in Plasma Technology

water vapor at less than plasma temperatures looks like contrails… at plasma temperatures it looks like the shuttle coming back through re-entry… that looks like a shooting star. Nasa does not post images because the image of the one that blew up looks much like ones coming home safely. How that is not going to be visible hundreds of miles away, would be a good start to explaining something that practical science shows to be false.

There is way to get rid of contrails and remove the sonic boom of the wing tips, by forcing the air to move through channels then having it drop off a razor sharp edge into air moving off the same way so that it creates a flat contrails that is not visible but the heating of the water vapor into plasma is going to create a huge bright white area in the sky (red at sunrise or sunset) and kinda defeat the purpose of stealth…

When air moves around a lift body you are getting pressure which disturbs the air, you can get rid of that by channeling the air like using a sword instead of baseball bat but once you break mach one, there is what amounts to fuel air denotation that follows you the faster you fly through the air the faster the air is deflected off the surface of the craft. I blew out every window in withca tall falls, TX and blew apart a brick building because I through I knew how much space I had to fly in and how fast the top speed of the air craft was. I had to pay for all the windows and rebuilding the book store. The base commander helped out since he made the call but that town was over seven miles away from where I took off pretty much straight up. If I have gone move level I would likely killed someone. As it was it simply craved a swath of destruction through the town while everyone was a church. If a single person had died I would have lost my wings, as it was I learned a valuable lesson and a whole town got new windows. Know what the air actually does around your craft and never assume the specs are correct on the aircraft. The DOD and NASA require the speed to listed on that aircraft instead of mach one but mach seven. I found out the hard way the cockpit was fused by metal freeze to weather striping due to plasma retry speeds. The rescue crew had to use a circular saw to cut through the lexan canopy and I had welt where the pressure cuffs were on my wrists and ankles. I was standing around after the landing being yelled at when I passed out as the blood rushed to my head. Plasma is nothing to mess around with, learn what it actually does to the surface of an aircraft before you get some pilot killed.

Oh wait, now that I notice that we were on the different topic, I’ve thought your talking about what I’ve posted.
Thus, what I read from what I’ve brought is, that they aim to achieve control over boundary layer and moreover, flow separation by controlling pressure using APP produced by DBD. Though, DBD to be actually applied on a fast moving surface seems unlikely. My post is about application of 3 dimensional discharge on IWB to achieve plasma stealth for an opened bay and a more laminar and stabilized flow created by APP generation.

First you have to start with what plasma is.

a normal airfoil works by sweeping dust under the carpet so to speak. A normal person can picture a lazy person sweeping dust under a carpet and then having to walk over bump in the floor. This is what a prop does to move across the surface of wing faster along the bottom than the top so the pressure increases under the wing, much like inflating a ballon easy to picture.

plasma is to most scientist water vapor that burns into a gas which has a specific heat great than the vapor point. That sounds like mumbo jumbo to most people. So with out changing what it is you explain it as water that is heated until it boils forms separate oxygen and hydrogen molecules that when they crash back together as super heated gas. The easy way to think about it is that usually when there is no salt water vapor most stable state is two hydrogen spinning around one oxygen atom or if you use an xray four oxygen atoms that have eight hydrogen atoms looping through the whole cloud of gas that moves like a liquid but floats when any engery is added, which are called thermals or thermal drafts. Lighting follows the paths created by these as the various water vapor modules swap their hydrogen atoms through other close clusters of water vapor. When it is a weather thing they call it water vapor, mist, fog, contrails, and clouds. In science this same thing is called vapor when it is below the vapor point and plasma when it is hotter than one hundred degrees c’ or two hundred twelve degrees f’.

So you have vapor moving across a surface, the inertia of the metal is not going to move and does not trade ions for the most part except on very small amounts with vapor moving across it. So the vapor ions bounce off the metal and increase in speed. The ones further from the metal move slower as they do not have added energy of bouncing off the metal. This something the write brothers figured out at kitty hawk with the first airplanes. You can note that the name on the first upside down airfoil is byod not write for a reason. Inventors generally forget to file paper work as they are out drinking and partying because they did something new and interesting. I don’t know who fault that was back then but when I see people who say they understand plasma moving across a lifting body and have no idea where the fast moving air is, are usually file clerks or patent trolls not actually scientists. I have no respect or sympathy for them. If they said they were paying for the design that is one thing but people can not figure out the basics of shooting the rapids while white water rafting really should not be claiming to be inventors or scientists. I have a meteorological degree I was supposed to finish up and I have no idea if the course every all got transferred to the air university which include hydrodynamics, fluid dynamics, thermal convection better known as thermodynamics, fluid modeling, with the aviation model, the pvn model which I don’t even remember what it stands for as well as particle physics and several other disciples. It is not the science that is usually the problem but when scientist try to explain something and five other people look up synonyms and simply claim it is different thing. There are a lot of very smart people that can not tell you that a vortex array is a series of fan blades. They use vortex because they want the physics effect you see in a toilet as the water drains. It is actually not the correct term but explaining that most fans move the air / vapor / plasma around the edges of the fan effect not through it, is usually only worth explaining by trying to talk through one. Put a desk fan on a desk and speak through it the air that moves forward that misses a fan blade or more importantly the air moving around the blade you hear. Everything else is scattered. So to explain that a turbine works by sucking the air through the center not the outside edge as they usually actually do, they call it a vortex. It also does not move in a straight line but moves like electrical current around a wire not through it. But when working with people who don’t actually understand science you see patents that are exactly the same concept and design granted because the patent examiners have not been required to do due diligence for years. Likely part of that plank – Eisenstein mess. Plank worked for the US Army as government issued scientist and his job was to make sure the designs that came out of the research belonged to the united states government and no inventor would be able to prevent the military from using a technological advance made possible by our school system and economy. Plank was littelry dumb as board. Some of the notes you could read when I was growing up about the Manhattan project and the puns and inside jokes they were making about him likely did not help the issue. But as far as plasma goes, pressure moves objects, the heat removed from plasma and applied to a lifting surface makes flight possible but I can put a rocket on a plank of wood and have it fly faster than an airfoil. A knife or sword cuts through vapor much faster but the whole point of super heated air is to increase the air pressure. The best example is a goderds rocket engine or the A-10, the wings are not lifting body but weapon racks. You can shoot off both and still fly through the air as long as you have on turboprop because the fan in the turbo prop changes angle to move air from in from of the engine to behind it, create suction or vacuum in front of the engine and more pressure behind it. It is simply lack of understanding what pressure does.

So, are you basically saying that the theory of controlling the airflow using plasma is nothing but a nonsense? Just asking this from a pure curiosity due to the fact that I’ve never studied fluid dynamics which, I don’t actually understand anything but that this is hardly to be done for an object flying subsonic or trans-sonic according to what you mention if I understand it correctly.

Thus

“The boundary layer is characterized by fluid laminae that decrease in fluid velocity relative to the body surface as a function of proximity to the surface. The flow in the boundary layer may be laminar wherein fluid laminae of different velocities create a smoothly-varying velocity profile to follow the contour of the surface. Downstream, however, the fluid flow in the boundary layer becomes turbulent wherein additional time dependent velocity perturbations occur in the fluid, creating additional mixing, however the mean flow continues to follow the contour of the surface. This turbulent boundary layer has higher mean velocities near the surface due to the additional mixing and is less susceptible to separation than a laminar boundary layer. In geometry regions where the surface turns too rapidly, or shock waves occur, the fluid flow may separate from the body surface, resulting in relatively low pressure and reversed flow near the body surface, thereby contributing to increased drag, a reduction in lift, or reduced control effectiveness. “

this part. Have You just read through the whole paper? It’s not there on what I’ve uploaded so. (I’ve only used those thesis in order to show that there are some studies among the flow control using plasma)

Oooshiny – Are you sure you got your links right because some don’t mention what they say in your post? E.g. the first is a plasma etching method.

The person who wrote those was working off someone else’s notes. Most of the information is basic fluid dynamics, it is slipsteam theory, but only in reverse. That might work on paper but not in reality.

Stands out the most glaring piece of blatant lack of understanding. If you want fast moving water in a current you see the fastest moving water is closest to the slow moving heavier silted water with more inertia. When the fast moving water moves past a submerged object the hard vacuum is created around the object as the water has further to go thus has to move faster as the space down river is emptied faster than the space next to it. This is how white water or rapids develop. People don’t shoot the rapids to go slow…

searched turbo prop found fifty invalid patents for afterburns and turbines using languge that the patent examiners should have caught and laughed at not issued patents. Pratt and Whitney a company that made them back the late seventies through now even got in the act and wrote up a patent for using jp-8 as new and uquie idea that is part of every turpo fan they make with an after burner in 2008, decades after they built and sold the first one… some one needs to just fire every patent examiner.

This thing was posted early last month on the “modern military aviation” board and I’ve got suggestions to post this on a dedicated post (Thanks to TomcatViP)
Below this is almost a copy and paste of what I’ve wrote on the other thread.

First, I will introduce u guys about a recent groundbreaking result of ADD’s R&D on plasma, which is, a flexible electrode and its application, a Wearable Plasma Fabric – its always something wearable or elastic these days ヾ(´∀｀○)ﾉ – or a WAPP(Wearable Atmospheric Pressure Plasma) fabric, which is a gas supplier independent system, therefore doesn’t needs a gas supplier to supply Argon or Helium unlike the legacy plasma producing electrodes in order to create plasma.

[ATTACH=CONFIG]252922[/ATTACH]

As you can see here, the electrode necessary to create a plasma from the atmosphere is in a flexible fabric form.
Until now, it was seen impossible to create a 3 dimensional electrode but only a simple shaped flat-surfaced ones.

Anyways, there are are various possible application of this WAPP such like wearable plasma anti NBC protective suit or detoxification blanket against hydro-soluble chemical weapons and so on.

fig.2) dissection of plasma blanket – abstract from “100 new major patents of ADD ver. 2016”

fig.3) weaving of WAPP and fig.4) possible applications – abstract from “100 new major patents of ADD ver. 2016”

Now, plasma, apart from its various useful characteristics, also acts like a very effective RAM, absorbing electromagnetic waves of an incomparable bandwidths/wavelengths with even higher energy. Applied on an aircraft, one may achieve a lower radar signature even compared to those 5th gen design without current aerodynamic-unfriendly stealth profiles but in a rather conventional and “more aerodynamic” 4th gen form.
Apart from plasma stealth, it is also known able to control the flow of a fluid through use of plasma, which means an unstable and unwanted flow of air caused by IWB or any other compartments of the aircraft can also be controlled by the plasma created by WAPP, stabilizing the flow and more over, improving the aerodynamic characteristics of the aircraft without major structural change.

For now, the plasma stealth technology will only be applied on vital parts for decreasing the RCS, such like IWB of the KFX.

abstract from “core technology priority planning for national defense (ver. 2017)”. part in red box reads : IWB RCS reduction technology through use of plasma”

“Study of Aerodynamic Drag Reduction Using Plasm Flow Control” – 2012

“Flow Actuation by Plasma Actuator With Different DC Discharges” – 2015

Well, above studies doesn’t emphasize the usage of WAPP due to the fact that those have been written before WAPP was revealed, though there are already research programs going on such like “flow control system using 3 dimensional surface discharge”

In page 48, it states that WAPP can create plasma state oxygen and nitrogen. fig.1) shows the legacy atmospheric pressure plasma generator and its application, namely : [(dielectric barrier discharge and downstream processing), (Corona discharge and In-Situ processing of wafers), (plasma torch and In-Situ processing of textiles) and (atmospheric pressure plasma jet and medical sterilization & decontamination)]. As one may see, those legacy APP generators are not suitable for aircraft application and like what I said on the top, needs a gas supplier to supply necessary gases like Argon or Helium in order to create plasma.

In page 49 part 3, it states that WAPP’s TRL will reach level 5 by September this year, so there are long way to go for WAPP to reach TRL-9 but KFX still needs around 8 years to get fully developed so time-wise, there ain’t no problem regarding it. In part 4 are the listed further R&D programs and the possible application.

Its been applied for a international patent in the US and Germany so if you have interest on it, you may search for it few months later when it gets registered as a PCT patent.

Overall, unlike shady plasma stealth technology of PAK-FA which is still in the dark in the ocean of rumors, ADD has revealed quite a lot of information regarding the plasma stealth technology using WAPP which is to be applied on KFX. I guess DAPA may use this as a jack on their hands to get more out of the US like sensor fusion technologies as an offset for exchanging technologies. Well, that’s what Japan did in the 20th century developing FS-X or F-2 so why not Korea?

P.S – I’ve posted this also on the other forum and copied it here so if you find this post somewhere else, that’ss probably written by me.
