Irianian stealth aircraft?

I am a non expert, however I feel that this is plausible.

The original F117 is thirty years old. The paper that dictate the theory of stealth (Russian theorist) is older and I assume freely available as it was published in a journal.

In the last thirty years, the amount of computing power that can be purchased by Iran will still be high compared to US in the 1970s despite sanctions. Iran already builds jet aircraft, small jet engines, so they have that technology.

There was an article her in Australia about a group of scientists that were trying to develop stealth technology. They started by going through publicly available material (on stealth material and theory) and starting from there. Apparently they were able to make very good progress and catch up most of the gap with the USA by having a go and reading publicly available information.

Iran is no doubt behind the west in terms of technology, however they do have a degree of skill. They make their own tanks, small arms, missiles, jet fighters, jet engines, can perform uranium enrichment and have even put their own satellite into orbit on their own rocket. So attempting to build a small drone that was designed from the very beginning to be a stealth aircraft may well indeed be true.

One thing that has struck me with innovation, is that a lot if high technology, but equally a lot is hard work and trying new ideas. Iran has a lot of people, and no doubt many of these have been tasked to develop stealth technology. They have had time, money, people, access to modern computers, modern technology, publicly available journals and the will and intent,,,,, thus I feel it is indeed quite plausible.

Look at the US - they have thrown tens of billions at the F-22 and F-35 and even with the experience from the F-22, they are still years away from fielding the F-35. According to the link, Iran currently have a one-seventh scale model, yet expect to have the full scale operational production model within 8 months. If that is the case, you have to ask, just how sophisticated and effective an 'asset' it will be? :rolleyes:

1. Without all aspect radar pole testing, attempting to build a reduced radar cross section aircraft is futile. This type of testing is conducted on large scale outdoor RCS test ranges. These have to be outdoors because of the variety of ranges needed to be utilised for various radar types, to evaluate the measures used in any LO reduction.

Google Earth shows no less than 7 such facilities in the United States. I am not aware of any such facilities in Iran.

2. So far they've built a scale model. No aircraft has been produced. I would suggest that any production aircraft would require more than one test flight...


Peter,

The United States has spent more than $1 TRILLION dollars on researching and deploying it's last 3 LO combat aircraft.

This alone suggests that it is neither easy, nor particularly affordable and I would strongly suggest that a thorough read on open sourced literature on the subject is going to be of precisely ZERO use whatsoever in producing a practical aircraft... Research and extensive testing based on the general principals is the only way it's going to be achieved. Significant LO effect is in the materials. Think the composition is available off the net?

The theory on how to build a nuclear reactor has been around for more than 50 years, yet nations STILL struggle to build them...
 
ok

take it easy, no need to give me the third degree. I identified myself as a non expert, thus no reason to feel threatened by my points.

What I was trying to get at is that Iran may well have been trying for decades to develop stealth technology. Thus they may well have had scores of people doing basic R and D on stealth material continuously for 20 years.

As to my reference to what is in journals,. I was going by what I read in the Age newspaper. In that publication there was an article about a group of Australian physicists, they may have been at DSTO, I cannot really recall or not, and the article referred to how they were given the task of developing some stealth technology and how they went about it.

Now the Age Newspaper (it could possibly have been the Australian) referred to how they went about it and referred to the physicist reading the available literature. Now it may well be that there was a degree to disinformation there, in that they had access to classified material but chose not to admit it. I do not know.

Now I do not see reference to F35 and F22 as relevant, as I see it they were trying to build a simple drone. Thus a first generation aircraft like the F117 would be a relevant comparison. I am sure if Iran could build an F117 clone they would be happy, how long will it take them? it took the US 31 months, for Iran, it will obviously be much longer, time will tell. No doubt Iranian aerospace engineers have poured over photos of stealth aircraft to learn as much as they can from there. I know there are books on stealth technology, which you may well laugh at. But take that as the start and add a good twenty years of trial and error with materials and I feel that it is plausible

Your point on outside testing areas indicates that they are not near the final step as yet, so any aircraft/drone is still some way off. You obviously have access to more information than I, I do not work in the military of military technology field.

Iran producing stealth planes? Pfff they don't produce normal planes so how they can produce stealth planes? I don't believe it. They produce unguided ballistic missiles, they produce 2nd generation tanks, small arms, some weapons systems on ships and vehicles...

But producing this kind of planes is not going to be easy. Iran is not producing even 4th generation planes, so forget about stealth planes. But they can produce same kind off planes like the rebuilded F-5 jets with MiG-29 engines but with better radar absorbing/deflecting material like the F-16's produced with gold glass canopy. This kind of technique makes the radar harder to spot it like a jet and takes more time to show up on the radar. This kind of smart techniques will maybe used for Iran's new jets.

No comments on Iranian tanks, everyone knows that they produce tanks with common sloped steel armor and a 125mm smoothbore gun. Most parts are canibalised from M48 series and M60A1 tanks. The Zulfiqar's hull, looks similar to the US M1 series hull, the turret has a mix of Chinese and Abrams style. But yet, it is an Iranian designed tank we don't know of it's operational status. I still believe that it is in a prototype status since the early 1990's. Maybe due to lack of funds and technology, or even manufactoring capabilities.

Comming back to the stealth planes, Iran is not capabale of producing a plane like the F-117, F-22, B-2 or F-35 stealth jets.

Nemesis welcome to defencetalk. I see you're a new member. Feel free to introduce yourself in our Intro's and Off-Topic forum, and tell us a little more about yourself.

Also before making a thread I encourage you to search through our forum. It's more then likely that the issue has been discussed before. In this case I suspect that the aircraft will be the equivalent of a combat-trainer, with a coat of basic RAM applied. Given that the aircraft is small, and has RAM, they may have a reduced RCS when compared to say an Su-27, or even an F-16. However I significantly doubt it will have any real LO potential, even when flying low and at a slow speed. If you look into indigenous Iranian aircraft projects; they all look like light combat-trainers. The level of sophistication in terms of avionics and systems-management doesn't seem to be even on par with conventional 4th. generation fighter jets. So we should hardly expect something competetive to be produced. Ultimately it's impressive that they produce anything at all, given their situation.

sorry for my title of my thread.

i had a debate with a guy from a different non military related site about his claim about the existance of this Iranian stealth aircraft. Here is what he wrote to me after I offered my opinion that this stealth aircraft claim is just propaganda:

His link:
http://english.farsnews.net/newstext.php?nn=8711152084

States that experts have already designed and manufactured the aircraft in a one-seventh scale and is ready for test flights. Iran's home-made radar-evading aircraft will join the country's fleet within the next 8 months. I criticized this claim by saying there is no way that they can make a scale model that hasn't even been tested yet into a fully functional stealth aircraft in just 8 months. He brushed my point of view by saying this:

START:
Well . . I am able to mention certain things and unable to mention others, regarding the latest Iranian Fighter-Jet project. So please clearly read what I have written so that you do not get yourselves into a frenzy of irrelevant postings that serve nothing but emotional outbursts.

Iranian Aviators, Engineers, Mechanics, Project Managers, and Designers think, feel, react, and respond differently to circumstances that their counterparts in Europe and US. You must first understand this before you can comprehend how Iran chooses its projects (aircraft or otherwise) and how it manages it, and develops its strategic needs and tactical requirements. These individuals that I am referring to are extremely sharp, very very knowledgeable, and would surprise all of you in terms of their depth and breadth as Aviators and Designers.

Additionally, Iran has multiple characters in its R+D, Project Selection and Funding, Requirements Analysis, and Strategic Needs. Each of these characters decide individually (almost) and head spear their projects based its interpretations and its own transformations during the progress of a particular project.
This is important since, as oppose to the European/US projects, the Iranian ones change shape almost daily and have to re-engineer themselves and their needs and project requirements. Although this is not constructive it is amazing to consider how Iran's characters have evolved through this intense amount of chaos and disorder to become excellent at managing a chaotic organization. Believe it or not, this does have some strategic advantage against US.

One of the characters in Iran is about sending signals to West through the projects that it funds, backs, supports, initiates, promotes, advertises, etc. that IRAN CAN DO IT. Now, "IT" refers to many projects that Iran and US had planned to perform together prior to 1979. The "IT" projects refer to Saeghae, Shabaviz, Shahed 274, etc. The groups that are unified and build this 'character' in Iran's Aviation are quite well known to many experts, no doubt.

There are many other Army, Navy, Air force etc. projects in Iran. Some of the other characters do not necessarily disclose where they are in terms of their capabilities.
They also have nothing to brag about, and nothing to show off about. They are extremely focused and highly competent individuals and organizations, both private and non-private, and they are the highest pillars of Iran's aviation characters (and most of the groups within each characters are quite autonomous in funding). Again, many of xperts no doubt know which organizations I am referring to.

Now it is well known, by many top level Iranian ex-IIAF and current IRIAF that the project managers of top strategic programs in Iran release enough information for strategic reasons. These reasons could include, among many others,
1) to recruitment of top Iranian engineers and aviators outside Iran;
2) to attract funding from Iranian sources outside Iran;
3) to retain many of the great engineers in the robotics and technology sector of the Iranian universities, etc. etc.

One such project that keep many Iranian engineers excited and founders supportive is a project from 1999/2000 called the Morgh Ashura.

This is an aircraft that "RESEMBLES PARTS OF THE AIRCRAFTS YF22-SU27SK-Chineese Stealth Fighter".
Read my statement very carefully I said it 'RESEMBLES", mainly in looks. I could be referring to air intake of one, wing design of the other, or such Partial comparisons to give an overall impressive of the aircraft.
This aircraft has some very advance features (I would call it 5th Generation), and some parts that are 4th generation, and some parts that are very old and engineers are working on all of these parts to bring to the most current level of technology and to integrate all these cohesively and intelligently.

In particular, the 3-linear directional thrust is quite interesting and it was something that German engineers perfected in mid 1980's when they were considering such technology for their version of the Eurofighter 2000.

The other technology that I believe is quite interesting is the computer integration, although this is not 5th generation, it is indeed advance enough (at least in my opinion) to cause concern for adversaries. Also, Iran's knowledge and experience in stealth (and believe it or not Iran does have quite a bit of knowledge and experience in this from the days of fooling Americans into thinking that Mig-25 was a threat) and this has been used quite extensively (surprisingly) in the design aspects of this project.

This aircraft will have many composite materials incorporated in its design, it will be somewhat stealthy, will have BVR capability, and it is aimed that it will also have very excellent maintenance ratios.
All of this is yet to be proven, so don't jump up and down your chair. It is a process of trial and error and a balance between US threats vs. perseverance of Iran's engineers/designers/founders and people.

Before you start getting into emotional reactions ("No Iran can't do it", "Yes Iran has built an aircraft the level of F/A22, F35", etc), please consider that Iran's aircraft (although it is actually 3 different modular designs) has reached the prototype AT DESIGN STAGE

This aircraft is quite an impressive endeavor by one of the Iranian 'character's and although Iran would need at least 2 more years to bring this into production, it is Iran's attempt to jump a few generations into the 4th and 4.5 generation aircraft development. In the next 2 to 3 years Iran will become a SWEDEN level aircraft designer and builder, although with more self-sufficiency than that of Sweden (Sweden purchases many of its parts from GE, Rolls Royce, etc.).

Iran also has many other projects that it is working on. More and more funding is being devoted to R&D and the industry is given more autonomy and more resources and priority. It is assumed that Iran needs a two pronged approach for self defense. This part (conventional airforce, army, and navy) had previously not received much priority - other than for maintenance and support. Now R+D is given a very high priority since some times now

Please read the above statements very carefully before you knock yourselves out with assumptions, exaggeration and/or rebuttals.

Then i showed him this link:
http://www.tehrantimes.com/Index_view.asp?code=188509

States: "Iran’s new stealth fighter will make its maiden test flight by the end of summer 2009." Meaning that they claim that a scale model that has just begun testing will be a fully fledged stealth aircraft ready for taxi trials this summer.

Then I showed him this link:
http://www.weeklystandard.com/weblog...ter_latest.asp

Again he brushed off my links as "unreliable sources."

Ask him about RCS-reducing techniques. While my knowledge on this subject is rather limited, I know there are other members here who understand the subject extremely well. It will either expose his ignorance on it, or provide us with some very interesting information (in the highly unlikely event that he really has serious evidence of Iranian technology aimed at LO signature platforms).

EDIT: Just noticed. The Chinese Su-27SK is not stealth. It's a regular Su-27S with the K denoting Kommercheskiy (i.e. commercial or export version). Nothing stealth about it. Also has absolutely NO similarities to the YF-22, other then that both are twin-engine air superiority planes. He's bullshitting. Call him out on it and provide tons and tons of links. There is a wagon-load of open source information on the Chinese Su-27SK which he calls stealth.

NEMESIS i think Feanor has hit the nail on the head.He talks about "Stealth'', the proper wording is LO=low observable.I have to laugh at the fact its a F-22/SU27("resembles:eek:nfloorl: )It sounds like propaganda in my opinion. They may be able to build a plane,tank ect but as has been mentioned at what capability/technology.

In my opinion,every NEW project has to overcome problems in avionics/computers/materials/engines/enginering/project management and finding a skilled workforce.I can see IRAN building weapons platforms and weapons but not at the "ADVANCED CUTTING EDGE" of Western/Russian/European weapons and systems.

To purchase second best weapons systems/platforms=2nd place in war.

I noticed this error in his beloved essay too, but it was hard to say what he was trying to tell. it says:

"This is an aircraft that "resembles parts of the YF22-SU27SK-Chinese Stealth Fighter".

At first, I thought he meant a Chinese Su-27sk stealth fighter. But it could mean he thought the Iranian aircraft resembles the yf22, su27sk, and a chinese stealth fighter. This part confused me.

The SU-27Sk is a Russian aircraft designed and built by Sukhoi. This is the SU-27SK:

http://www.knaapo.ru/eng/products/military/su-27sk.wbp

It is NOT Chinese...

The YF-22 was a United States aircraft prototype designed and built by Lockheed Martin for the Advanced Tactical Fighter program. This aircraft competed against the YF-23 aircraft.

The YF-22 was subsequently selected (not without controversy of course...) and was developed and became the F-22A Raptor, which is in-service with the US Air Force.

The SU-27SK and YF-22 share absolutely nothing in common and do not look anything alike...

Cheers.

Hi Aussie Digger,

YEs I was aware of that :)
I was jut trying to interpret his essay. A chinese Su-27SK??? I laughed when I heard that

A chinese Su-27SK might have meant the J-11 (or just a Su-27SK in Chinese service). Anyways, did you get a reply from him yet?

I did get a reply from him...... with nothing to back up his claims. all he is saying is if i have nothing good to say, dont say it at all.
