The T-50 (PAK-FA) Thread

[GGTharos]

I wonder if they were able to fit as big a bay as they wanted ... the S-intake stealth feature is obviously missing, but there's other ways to stealth the engine faces.

Gay marriage? Wow, what a level of imagination!?

 

Both the Sue and the Black Widow are female, so... ;)

[4c Hajduk Veljko]

They did a pretty high AOA take off for a first test flight :)

Good observation!! Also, that thing went up in 40+ degrees climb!!

[GGTharos]

The wing is definitely raptor-like, but with more LERX. The vertical tail isn't anywhere near as gigantic as the 23's, and there's no missing horizontal stabs.

[GGTharos]

Not really. The takeoff is a standard 10deg pull up, and the AoA will be less that that. You do a whole lot more than 10deg, you'll smack the tail down.

 

And a 40 deg climb is nothing that hasn't been done before - even a clean F-15E can do it ;) But it's definitely better than most of the 4th gen fighters which need to use AB for it.

Anyone has a PakFa blueprint?

:D:D:D:D:D:D:D

[Bucic]

What a flat feet! :D

I wouldn't expect high roll rates along longitudinal axis...

Horizontal tail arm (leverage) is very short too and combined with what looks like relatively small horizontal surfaces area...

I wonder how they are going to achieve proper agility. Or did they gave up on it in favor of other design goals.

I'm glad sukhoi made it similar to the yf-23, At least its coolness didn't die (no I'm not saying that sukhoi copied the yf-23)

They are small but remember they are full moving parts not just rudders, and I think they work together with the elevators + the vector control

:lol: lol - stereotype nailed!

 

Something else you may be able to help with Hajduk - you being from an agricultural part of the world - can you shed any light on which tractor they stole to get the back wheels on the landing gear?

[Bucic]

Would you be very surprised if it was the first flight that was supposed to be recorded?

No, perhaps I should not be. Still, pretty good security measures to prevent pictures leaking out to the media before yesterday.

[GGTharos]

This is just a matter of following a climb schedule ... the climb angle is just a matter of maintaining speed at throttle setting.

[Krippz]

It looks great! Let the RCS speculation begin :D

[Pilotasso]

The biggest speculation wont be the RCS. It will be how draggy it will be.

 

Looking at this design, the feeling I get is that this PAK FA is to the flanker the same way the super hornet was to the F/A-18C: a new plane but built on extensive experience gained on previous model. And thats not all in common to both. Like the Superhornet , PAK-FA looks bigger, has got larger LERXES and Im willing to bet, a massive drag penalty.

 

Either russia manages to turn that lerx into a a wing or this plane gonna suck some knots in turns.

I think that the raptor also creates lots of drag since it has big delta wings but compensates with the engine power. One thing to note is that the pack fa is a big lifting body and may have low wing loading. They design this jet like a flanker to retain airflow symmetry at high aoa

[gigz-on]

Yesterday Sukhoi said that they've already painted T-50.. :)

I wouldn't consider F-22 wings as classic delta wings.

And what would that "airflow symmetry" be exactly? :)

[Pilotasso]

F-22 has large wings yes (It still is faster and more manueverable than the F-16), but the PAK FA has a larger surface but on LERXE's I have not looked into the specks of its engine yet, but if it isnt more powerfull than the ones on the raptor its going to be an airbrake. But lets see how this prototype phase evolves.

Something that does not produce any lift at all?

[Bucic]

Something that does not produce any lift at all?

May be, but my point was that mikoyan probably misused the term / was not aware of its meaning.

[Flyby]

Russian stealth fighter flies?
