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.
too bad that is match move over a clean plate of skill images. next time they should at least take the time to film the sky before post working a computer generated model over a low resolution image. I can recommend looking into nuke or shake (if they use mac computers) but really they should actually build it if they think that image can fly. Enough thrust behind anything can fly. Look at an A-10 the wings are not flight surfaces just weapon racks they could not figure out how to justify any other way. The control surfaces on an A-10 are next to the engines like every other truboprop design. A turbine can use a different type of surface but the odds are those are simply designed to look like rounded corners, the after burner choke is from the F-16C/D version, the other parts are likely copied off other designs so no one asks why the contract for space liner is not getting worked on. It would be comedy but I don’t want to have to pay higher taxes for comedy I want actual designs and eventually space yatchs and space fighters. But really the point of the T-38 is to understand super sonic flight and a left and right side propulsion. At less than mach one having four left turning smoke shifters is no big deal but at mach they have to spin into each other or you can only use one. Pilots fly the T-38 so they learn to go left you need less push on the left or more push on the right. To turn right you add more power to the left propulsion system. The F-16CJ model does use a choke like they have in that image but when the choke is closed the slipstream effect is far more extreme and the speed is fast enough high speed camera’s have trouble when on a fixed mount. That image above looks like a chase car is filming the air craft as they fly by at stall speed about fifty to six miles per hour… I can see 140 mph but reason anti aircraft guns lead incoming air craft is the rotation speed is not fast enough to film that scene. I need to see if I can find images of Boeing work on the C-130 Hercules when they added an air-conditioner and claimed it was a new air frame. Well that is one less company the military needs to worry about bidding on the new trainer… they were a supcontracter working on getting enough of the original design up in the air and clearly they don’t even have a designer who can take their cnc data and toss it solidworks or autocad.
Some of the most detailed info that is still sanitized is https://defensesystems.com/articles/2017/04/26/f35.aspx not sure who they are owned by but them and https://fcw.com/home.aspx seem to have the most info on actual direction out side of the navy times or airforce times.
The F-35C is likely not cracking the bulkheads from a particularly wet landing anymore but some of the concepts they are trying to use a stepping stone for training pilots to fly their supersonic research design is like a swiss army knife with too many attachments, I have carried both and my leatherman got more use because the blades were only designed for one thing. I think if they want one size fits all they really need to be able to accept some of their existing tech can not just be wrapped in tin foil and call it good enough. Some of it works great some of it does not work and needs to be updated but congress kept saying they would get money for an upgrade but not a new plane.
I remember when they were trying to decide what to call the block of engine on the modern viper so that it would have bigger or larger number than their competitions design. Loading an F-16A and loading an F-16cj is very different. I think but I could very well be wrong but I think the us military blew up an aircraft rather admit they lost the paperwork that went with it. Sure it had amx rounds loaded in it but those could have been unloaded by booting the hud tapping the button for amx punching in the code and unloading them. But then again their is a company that pulls a working airframe off the flight line and delivers it to another base after painting the outside to look like the aircraft that is down checked. They have gotten in trouble for it several times but they still have jobs for some reason. So likely have the reason is that instead of playing games contracting they should just pay for air craft on delivery and if a air frame needs work turn it over to company when they deliver a replacement and once they fix the one they got after delivering a working one they can sell back to the military.
The F-35 joint strike fighter was a laughing stock when it was designed. The end goal they are working to with the F-35C is likely a fairly decent air frame but things like the helmets, they have viper helmets that don’t have this issue but they cost more because likely they have to pay some company that used to make weather stripping or something. I know when I wore one the black rubber gasket was two inches thick and the gas mask had pins on the side. The whole thing does not move away from your face but every helmet has to be built for one pilot you can not swap them.
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.
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.
“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. “
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.
I remember the first time I got to see one up close and I got to see a Thunderbolt II because all the warthogs had been given missions and we were only allowed to work on craft that did not have an active mission at AETC bases. It is one of the few air frames that can angle the turboprops in different directions. Most fighter jets the after burner points one direction and that is what you get. The F-35C is likely the first new fighter jet to have a directional afterburner assuming lockheed got that in the revised spec for the F-35’s to make them more useful and appealing for export at some point. But tangent aside the warthog name change came because of request for a built in map screen, instead of a paper map. I don’t know who set that in motion but I still think the older name is cooler, even if the new consoles are more useful.
