In this picture there is a mistake: PAK FA Range is not 2000 km
Prime Minister Vladimir Putin, who described the first flight of the fighter as "a nice event," promised that "in 2013 should do the first batch (PAK FA) in the Armed Forces, and in 2015 already begin serial purchases.
In turn, the head of the Defense Ministry Anatoly Serdyukov has expressed hope that all the time to supply the first batch of aircraft will be met[/U].
New Recruit
Pigs are worshiped in india and thats quite a shame for the 21st century. ewwwww.
Rats, pigs, cows, dogs, monkeys, elephants. woow. no wonder why you guys act so not differently on this forum.
that only defines you indians..
I M LOVING IT...
Ok guys I wasnt able to post anything for sometime but I did keep a tap this thread, and let me tell you it gave me a lot to laugh about over the time. School boys talking about things that they cannot even imagine lol. I was talking to some of my friends at Sukhoi and I mentioned some of the post here to them and only thing they did was laugh and laugh really loud. They told me that they will register on the forum to post their input soon also. Ok so as I am here I shall try to debunk some of the claim that many Pakistani members are making here
amalakas I wasnt referring to you when i said said "School Boys", I have read your comments and they make sense till now. In regards to the questions you have aske, they are too broad and require way too much information. When one talks about visual stealth we do not refers to Mr.India type invisibility but concealing the aircraft as much as possible. It is quite an obvious answer that true visual stealth has not been achieved by anyone yet. If you want to know more about how visual stealth please search about it on Google. There is enough info about it as it is used on the F-22 as well as the B-2 spirit.1) Not all of us put down the PAK FA.
2) For someone who is supposed to know so much, you are just repeating well known and trivial facts about radar and stealth.
3) Not all of us in here are school boys.. some of us have PhDs.....
4) You have friends in Sukhoi..how come they didn't give you any more solid information than a wiki would..strange ?
5) The fact that they laugh at this thread if true doesn't mean much..most developers try to laugh off competing designs.. its only after that real strengths and weaknesses are revealed.
Millions of volts one the wing leading edges ? Electricaly charged skin ? ......... you do realize that the Voltage is applied in a pair.. you can't have positive without negative .. which way would the polarity be? To expell negatively charged particles from the rear ? how ? is the PAK FA going to have an ION engine ?
You do realize that the color of the sky you see from the ground is not the same you see from above or sides or sides from a distance ?
is the pak Fa going to be calculating the angles of refraction and produce different colors for its top, bottom and sides ?? and do that constantly ? .................................. wow.. .. and if it flies over the sea ? is it going to turn dark blue on the top ?
P.s. having a PHD does not guarantee that your smart and know what your doing
Hahahahahaha ..that is so true actually...
Yes...Quite often it is the Russians and the Chinese who are comparing the PRAT-FALL with the F-22 and F-35. lol.People here dont understand the meaning of Prototype lol. And those who dont should not be on this forum. Really guys common its the first time this jet was unvelved and people here are already comparing it to the F-22 and F-35,...
But did you just criticize others for making comparisons?In its final form the PAKFA will be by all means second only to the F-22.
If a PhD does not mean one knows everything, as you said, then throwing plenty of money at a project does not mean it will succeed. Right, comrade?Enough money and expertise is being poured into the program...
I do. At least some....and no school boy here has any idea the amount of work that goes into getting an aircraft of such magnitude into the air.
Yes...We shall see.Let me explain stealth tech...
The language is crude but acceptable.The idea is for the radar antenna to send out a burst of radio energy, which is then reflected back by any object it happens to encounter. The radar antenna measures the time it takes for the reflection to arrive, and with that information can tell how far away the object is.
All bodies, from organic to metallic, reflects an impinging EM wave. But essentially, a hard body, such as that of a metal or even plastic, reflects more energy.The metal body of an airplane is very good at reflecting radar signals, and this makes it easy to find and track airplanes with radar equipment.
Nothing is 'invisible' to radar detection. We can detect raindrops, albeit in cluster, but detect them nevertheless.The goal of stealth technology is to make an airplane invisible to radar.
No violations of the laws of physics here.There are two different ways to create invisibility:
The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment.
The airplane can be covered in materials that absorb radar signals.
Wrong...A sphere or curve is a natural radar low observability planform due to the 'creeping wave' effect...Most conventional aircraft have a rounded shape. This shape makes them aerodynamic, but it also creates a very efficient radar reflector. The round shape means that no matter where the radar signal hits the plane, some of the signal gets reflected back:
Creeping waves greatly extend the ground wave propagation of long wavelength (low frequency) radio. They also cause both of a person's ears to hear a sound, rather than only the ear on the side of the head facing the origin of the sound. In radar ranging, the creeping wave return appears to come from behind the target.
Wrong...You are seriously out of date, buddy. First...What is casually thrown out as 'stealth' is properly called 'radar avoidance' or being a 'noncooperative' target. An airliner is a 'cooperative' target, it wants everyone to know it is out there. In contrast, hostile aircrafts, be it a fighter or even the giant C-5, because they have hostile intents, they want to be 'noncooperative'. Second...Flying below the radar horizon make ANY aircraft a 'noncooperative' target, hence automatically a 'stealth' aircraft. Throwing out a lot of ECM measures also make an aircraft a 'noncooperative' target.A stealth aircraft, on the other hand, is made up of completely flat surfaces and very sharp edges.
Like what? Did you missed a copy/paste somewhere after the colon? Looks like you are lifting your arguments from someone else's.When a radar signal hits a stealth plane, the signal reflects away at an angle, like this:
In addition to what? You cannot say 'in addition' without giving the readers some previous info. You may want to review whatever sources you have the next time you want to copy/paste your arguments.In addition,...
The F-22 uses far less absorbers than the F-117 and it has a lower overall RCS. On the F-22, absorbers are most prominent on leading edges such as intakes and control surfaces. To achieve such radar low observability, the F-22 and F-35 uses mostly curves to exploit the 'creeping wave' effect. There are some angled faceting and some absorbers....surfaces on a stealth aircraft can be treated so they absorb radar energy as well. The overall result is that a stealth aircraft like an F-117A can have the radar signature of a small bird rather than an airplane.
No problem there.The only exception is when the plane banks -- there will often be a moment when one of the panels of the plane will perfectly reflect a burst of radar energy back to the antenna.
Proper word is 'faceting' or the phrase 'angled faceting'. The F-117 used this technique prominently. The F-22 and F-35 considerably less. See 'creeping wave' effect.One of the technologies that the PAKFA will unitize which is also used by the F-22 and F-35 is called Facing. Which is to incorporate angels into the structure of the aircraft so that it can diffuse all sort of signals such as radar and give it the so called Low observance.
What kind of explanation is that? Fly-by-wire in analog form was in the F-16. Prior to that, we have computer assisted 'stability augmentation' in mechnical flight control systems.The problem is that one cannot have 100% stealth because of the fact that the design must be able to fly. Even Aircraft such as the F-22 cannot fly without the help of sophisticated Fly by wire technology.
Not going to bother with this one.Another technique that may be used on the PAKFA but not yet confirmed is to charge the leading edges of the aircraft with millions of volts of electricity when in flight this pushed positively air particles ahead of the aircraft at the same time negatively charged are expelled from the jet exhaust. This will help push the aircraft through the air by softening the sound barrier an essential to the Super cruise theory and will also reduce sound and the vapor contrail of the engines. The created electric fields also eat into the radar waves further reducing its RCS signature. The PAKFA will also be coated with a electrically charged skin light emitting polymer paint. This will help the PAKFA in 2 ways the charged skin absorbs radar waves but will also glow when charged allowing the aircraft to change it brightness automatically to blend in the sky giving true stealth and invisibility even in daylight.
