T50's conventional cone shaped exhaust is not stealthy, hope china doesn't follow

The T50 still using the conventional cone shaped exhaust, that's not stealthy at all, whereas the F-22 modified that and have the wedge shaped exhaust. The wedge shape forms an incline to divert the incoming radar to another angle.

Also, the F-22 's exhaust got embedded into the whole structure and reduce the IR signature.

T-50's coned shape exhaust is Not only non- stealthy in terms of radar but also has no IR reduction whatsoever.

If China's J20, or Jxx follows the conventional exhaust then it wouldn't be a good design, just like the T50, having the same weakness.

From what I read its just temporary for the T-50 and after finalizing the design they will probably add more stealthier engines.

T-50 was conceived as a defence equipment, to deny space to other stealth fighters. The more intensive action to reduce signture was taken at the front of the plane. Indian aircraft will be different cause they will be attack planes.

Even its frontal is not very stealthy. Still having old style cockpit. The materials on the T50 look kind of shiny to be RAM material.

Can u see those blades in this picture?

Which way does a fighter's nose point when the aircraft is flying? Toward the enemies. What's the advantage of a stealthy tail when you are heading toward the enemies? None really, because they wouldn't see your tail at all. So why should Russia/China add extra complication to their design?

F-35 also has "old style cockpit".

It is highly unlikely that the J-XX won't have conventional exhausts and an "old style cockpit".

Once the plane inside enemy's territory or pass the enemy ship in the ocean, then those aegis radar can pick up the signature from behind.

Sure, It would be different scenario, if China's J-XX stay inland and only countering intruding stealth fighters.

But if J-XX ever come out from inland and toward the ocean then the back need to be stealthy as well.

#1) There is no evidence that China is following Russian approach. Early wind-tunnel model pictures suggest China is going F-22 route, but latest info suggest a design even more radical design than the T-50.
#2) Russian T-50 is a prototype. We have no evidence that the production aircraft will not have stealthy exhaust.
#3) Russia has gone for less stealth and more maneuverability in their 5th generation design. Even without stealthy exhausts, it may still be a tough customer for the F-22, as some analysts have said.
#4) It's possible that the protoype does not have RAM coating yet. Also, look how shiny this F-22 is:

The advantages are pretty clear really. It's to avoid falling prey to certain possibilities:

-The enemy won't always be coming from the front.
-The enemies could be stealthed themselves, so there's no way to know if one is always going to be engaging them head-on.
-The enemies could have their own rear stealthed, so conceivably they could discretely leave the battlespace without the other party knowing it.

My little understanding of stealth tells me that it doesn't matter which part of the plane it is. As long as it's a portion of the plane and it has the tendency to reflect radar signals back to its source, it's not stealthy. So if the tail is not stealthy in design, it could be picked up by detectors.

Plus, you can keep pushing your plane forward, but you never know where your enemy will come from. I still remember in the movie "Black Hawk Down", before the battle, one guy said to his fellow soldiers that "I'm not going to run away from my enemy!" so he took out the metal plate in the back part of his vest to lighten the load. Guess what happened? They were surrounded by enemy and someone shot that guy on the back. Without the metal plate, we all know what would happen to the poor guy... So you want to be as prepared as possible. Especially with something like designing a stealth plane, you have invested so much. You certainly want to be as good as possible and don't want to leave a big potential weakness for your enemy to exploit.

There's not blades, but a engine cover...
