The T-50 "prototype" is nothing but a money grabbing tool because it lacks stealth features.
As if a knuckle head like yourself has an idea of 'stealth' features. If we take the F-15 Silent Eagle, for example, most people like yourself would shout out the top of their longs that it is not 'stealthy' yet Boeing has acknowledges that it has a frontal RCS of the F-35, small details such as treated canopy, removal of pylons, 'RAM', radar blockers, masking canon, and other small details has reduced its RCS many times over. It's one thing if an individual with knowledge in 'stealth' principles makes an observation on how low an aircraft's RCS can be, it is entirely another thing when someone that is incompetent and utterly confused about 'stealth' tries to make a definitive claim.
Yes I think the Sukhoi engineers know exactly what they are doing. They a building a plane with the only purpose of making money. I mean, if the T-50 is as good as the Russian propaganda, why is Russia trying to sell it to EVERY COUNTRY including a western ally like Korea? Is America selling any of the F-22s?
Unlike you Sukhoi is not that naive, do you think that the Russian, Air Force, Indian Air Force, or Korean Air force would not test out the pak-fa before they purchased it or at least receive some test data on the aircraft? There is also nothing wrong with trying to sell aircraft to other countries. The F-22 is not being sold because of politics, although Lockheed would love to make money off of it, but that is where the F-35 comes in. Russia and South Korea also have a good relationship, it is no surprise that Russia is offering South Korea the pak-fa, after all South Korea operates other Russian weapons and even come to Russia for training and or using the vast Russian landscape for conducting military exercises.
On the surface of it, the T-50's shaping is just, horrible. Apparently the Sukhoi engineers haven't been able to solve the engine cooling problem so they have to total expose it without a serpentine intake and a flat belly. Sukhoi is also not taking small care such as the canopy and surface material. The plane is of just pure metal frame. Yes you can say "it is just a prototype", but it is the Russians who say that this plane will enter "production" in 2015! Just 3 and half years from now! That's some amazing development span you have there. A fifth gen plane that will be inducted just 5 years after its maiden flight!
Apparently you do not keep up with the times, do a search of the pak-fa and see what the designers claim for IR. And stop with the serpentine intake nonsense, people like yourself have abused and misused that word. Serpentine intakes have been on certain Russian aircraft for decades, if it was wonder method Sukhoi would have used it, but in stead that went with a radar blocker concept, the same concept that was used on the F-117 and now the Silent Eagle albeit both aircraft use different methods with one using mesh and the other a traditional set up.
Now as for the flat belly nonsense. There is no law or design principle that says a flat belly is the only way to achieve low RCS from the bottom side of an aircraft. The flat belly fuselage is the cleanest and simplest way to evade radar. The pak-fa's intakes are sloped, and interestingly enough they are faceted much like the F-117's nose was, meaning that when EM energy hits the intakes the EM energy behaves in a complex manner.
The Su-47 design was a huge fail. The Russians never solved the many problems it had so they have to ditch it for a more primitive design like the T-50, so don't tell me that they solved all the problems and don't tell me that exposed engine vents like the T-50 has any advantage to it.
The only thing that is a huge fail is this embarrassing comment. The SU-47 was only built for testing new technology, even before the pak-fa was a concept on paper it was know that the technology and experienced gained from the SU-47 would translate into Sukhoi's next generation aircraft.
Yeah, Su-47 is so successful that not a single one of them is in service. Go do some research. The plane was a huge fail. It is not even considered safe enough to fly.
It was a technology demonstrator you knuckle head, and please do explain how it was a fail, the aircraft gave way to new technology and it did what it was designed to do. And please do elaborate how it is not safe to fly.
No country builds demonstrators just for exploration.
Wow, am i really reading this correctly? Are you that naive and ill informed?
They wanted to build the Su-47 only to find out that Russia had no capacity to build material of sufficient strength to hold the Su-47's frame.
Yet it was able to perform high G maneuvers at both subsonic and supersonic speeds, mind explaining how it achieved this without the wings snapping off? There are plenty of videos that bust your claim out of the water.
The plane was about to disintegrate in the air at the later stage of testing.
Sources? And did it disintegrate?
Also, the engine problem was never solved because AL37 was no good and they did not have S117 yet.
You do know that the engines were a part of the testing technology correct?
This is why the Ruskies gave up on the project. Just accept it, they screwed up, so now we have a T-50 which has very few of Su-47's technologies.
Jee, lets actually take the time and see what technology the SU-47 had.
-TVC engines.
-digital fly-by-wire
-weapons bays
-composite materials
All of those are on the pak-fa and all are major systems.
People had expectation that X-series and all the secret project America is doing would become reality one day.
The X series was purely for testing, aircraft such as the X-29 explored different concepts in an attempt to gain knowledge an perhaps apply that knowledge to future aircraft, just like the SU-47. So what makes you think that Sukhoi didn't have expectations that the SU-47 would yield advances that would one day be incorporated in other aircraft? The reality is that the SU-47 had many technologies that were implemented in aircraft such as the Flanker series.
