But other aviation innovations are as simple as a fresh coat of paint. An Israeli nanotech company is claiming that it has created a special paint that makes planes, missiles, drones, and other aircraft invisible to radar.
The company, called Nanoflight, says it has completed an initial test run and found that missiles painted with its proprietary nano-paint are very difficult to detect with radar. The paint doesn't make aircraft disappear completely from radar instruments, but it is disruptive enough that it is very hard for equipment to register their signatures as incoming war craft.
Radar works by sending out electromagnetic waves and seeing what comes back. If those waves strike a solid object -- like an incoming aircraft -- these waves are scattered. But some of them return to the radar receiver, and a regular, repetitive returning of those waves produces a positive ID of an object. The nano-paint simply absorbs these waves and dissipates them as heat that scatters into the atmosphere. The radar might still pick up a few returning waves, but the signal is weak and irregular and generally wouldn't register as an incoming object.
It's not perfect, but it's cheaper than buying a stealth aircraft and could produce a cost-effective means for entire fleets to add a layer or stealth to their tactical portfolios. Nanoflight officials also claims there are civilian uses for the stuff, like protecting buildings from radiation caused by nearby high-energy power lines.
Something like this would have huge advantages, but it also means other unfriendly nations would unlock a future stealth fleet. Let's just leave Russia to its $100-million PAK-FA and see where it takes them.
So all the world's military paints their bases and vehicles with this paint. Looks like all that is left on the radar is the civilian stuff...
Im just saying that it could be bad.
Its not going to be that easy. Sure, this new paint will decrease the RCS of aircraft its applied to, but will they be considered truly "stealth" or just "Low-Observable"? Stealth is not just about the RAM(Radar Absorbing Material) that is covering the aircraft. It's about many different things that when added together, make the aircraft truly stealth. Things like, RAM, the shape of the AC, internal structure, avionics, thermal signature, etc. Sure, we can coat an AC with this material and make it harder to detect, but when competing against a plane that from the beginning was designed to be truly stealth--it's no contest.
I want to paint my car with that!!!!!!!
Besides the obvious threat from countries like North Korea and so on i could see drug runners painting their Cesnus with this... or better yet the Israelis might start painting their Synagogue and wailing wall with this it might throw off the terrorists they cant bomb what they cant see! haha
Setarip is right. Stealth isn't just about slapping a coat of special paint over something, it's the coming together of a whole lot of different technologies. There's a good reason why the US has been pretty much alone in stealth for the last few decades and is still the leader by far. Everything has to be designed to be perfect, like the plane's own radar and other electronics, for example. The cockpit has to be specially shielded, and the compressor blades of the engines have to be hidden from view, right angles have to be avoided and edges have to share as many common angles as possible. I recall that even a loose screw or slightly misaligned panel is enough to seriously compromise stealthiness. The Israeli coating may reduce observability by some degree, but I doubt that it's going to be that simple. An aircraft has to be designed for stealth right from the start and meticulously maintained at all times.
This should read...
Nanoflight officials also claims there are civilian uses for the stuff, like reducing the amount of disposable income available to irrational, ignorant, fat, smokers who blame the power lines for their back pain.
Check out the source article. Towards the end, they make some fantastic claims for this stuff that really make one wonder.
Maybe this stuff does have an impact on the RCS, but no one is saying how much -- OR -- if it will survive in the often hostile aviation environment.
This will all end in tears. I just know it.
MarcusM is right. Stealth from a military perspective, is multi-faceted. Also, one apparent downside is that apparently, it increases the heat signature. This paint does have possible applications as a car paint for the new Lamborghini with its stealth like angles and composites.
The US already had this. This "special" paint was used on the B-2. And during inclement weather, the paint would come off and had to be re-applied. Very costly.
So, is this an entirely new paint or did they just stumble into the thing the US already has? If not, I bet the Pentagon will want to sue for patent infringement.
This paint makes it hard to observe it with a radar, it's not an invisibility cloak for your eyesight. We are the staunchest ally Israel has. We will always be their closest ally. They get more foreign aid from us than any other nation. Along with the British, Harry Truman brought into existence of the state of Israel. As an American I would be very disappointed if I found out that Israel was doing anything against the interest of the United States.
I heard a rumor some years ago that Israel was working with Chinese military elites on projects that could be counter-productive to the U.S. Of course, I took this with a grain of salt.
The worst kept secret in the world is that we gave Israel nuclear weapons back in the 60's and they were about to deploy them in the 1972 Yon Kippur War. Golda Meir getting on the phone with President Nixon in the middle of the night stopped that, Thank the Lord.
If this paint is all it sounds like it is, I am sure Israel will make sure it stays in the hands of who actually made it possible for them to develop and research and invent all the wonderful things they can share with the world to make it better and a safer place to live.
If successful, this could be a huge step in military aviation. Stetarip is right, a fresh coat of paint on a C130 isn't going to make it stealthy, but it sure might help.
Additionally, i-tec has already invented a flying car.
The paint is conductive, consists of nano-carbon tubes and is mixed with acrylic paint suspension and carbon black amongst other material.
It is both obnoxious and ludicrous that this Israel company is claiming invention of this type of paint with the radar detection avoiding specifications because it has been around for at least 5 years.
Here is an article from 2008 - http://vvvvvv.spiegel.de/spiegel/0,1518,550691,00.html
Furthermore I know first hand that refinements of this technology was being developed at the University of East London and University College London much earlier using nano technology.
