PAK-FA new Pic analysis

[dbc]

Allow me to rephrase, I said give the Russians some credit, it may be that the wheel assembly serves as a radar blocker when the landing gear is folded in full flight. There are several creative ways to prevent line of sight to the rotating blades.

There is that better TamilKhan? Or should I troll it down some more...?

There was no need to drag in comments from an issue that is done and over with, and on which the respective parties have communicated.

Move on with the topic please.

F/A-18 E/F Radar Blocker

Nice picture. but hun...
You see the slop in the air intake? thats the radar blocker not the engine blades. In PAK-FA pic i dont see anything like it. maybe it will be placed later on.

That is up to you to decide, not for me to tell.

And thanks for your explanation, but as i am not well versed in military aviation affairs, so i did not get your point as how will the wheel assembly work as a blocker. As per the pictures and looking at other Sukhoi models, the wheel goes to a separate compartment on the side, so how will it work as a blocker, as from the picture i don't see any other interference coming inside the intake.

As per my study, all US built stealth planes have the 'S' shaped intake, so that radar waves do not find the fan blades, similar kind treatment is done behind to the turbine blades to hide them.

And as for the F/A-18 blocker, i had read that it may not provide full 100% blocking capability, and these blocking blades are variable, meaning it can be turned and when full power is required, the air engines need more air, thus the face of the blocker is to be opened up to let in more air inflow, thus the blades can be exposed.

Hope, you provide further insight.

interesting comment on WAFF forum.

Why would they build a prototype NOT showcasing how they will include hiding the engine blades? Kind of dumb, don't you think?

If I build a prototype, I'm showing you what you're getting. If it had to take a longer time to build a prototype with hidden blades, then so be it. Better late than never.

It's not smart to show a prototype that doesn't include key parts that are planned for the production version, imo.

You're saying the X-35 didn't hide its fanblades, simply because it was a prototype? Same with the YF-22? YF-23? Come on, man.

If what you say is even true, then they're still not going about it the right way. It seems they're trying to rush the program, and I think it might backfire on them, if so.

omg whats with people and " Analyzing" the PAKFA, its obvious that the word prototype does not ring a bell in many heads here.

@ Growler you have a nasty habit of calling people stupid, pathelogical liars, idiots...ect whenever someone questions the JF-17 but you go around making these threads...it's all too obvious what your intensions are.

What's this? It looks like the YF-23...interesting that its compressor blades are exposed but it had a smaller rcs than the YF-22.

Seems like you don't know what a prototype is, let alone radar blockers.

 

[ptldM3]

If we look at Russian engines pictures below, and compared it to the above picture, it can be said with certain confidence, that it is not the radar blocker, rather it is the engine.

May be more expert insight or some other clear pictures would be better to clarify the situation, but for now they do seem to be the engine fans.

AL-41 Engine

The fins in front of the AL-41 are NOT angled where as the fins on the pak-fa are angled.

Please read what has been written so far, the landing gear causing the air intake to collapse when retracted is mere speculation on my part. Since the alternative is to conclude that the Russians are stupid to call a plane with exposed blades a fifth generation stealth plane - a ridiculous notion to say the very least.

I suspect one of two possibilities :

1. Line of sight to the rotating blades is restricted by some unknown means in flight. Since the landing gear is in close proximity to the air intake I offered it as a possible candidate to act as a radar blocker.

2. The design of the air intake is not finished and a more ‘low observable’ re-design of the air intake can be expected in the future.

I wont worry about Growler and his "Analysis" if i were you. We all know why these thread's are created . Even before someone sneezes Pakfa, another so called "Analysis" pops up lol.

Got this from another forum

Insiders have spoken at Paralay's forum, and that's what they say:

* This is T-50-1, it's leaked and someone's head's gonna roll (there was another photo with bay doors opened, but it didn't spread)
* What we see is indeed the engine front: as I suspected, for the airframe testing it was decided to drop the engine shielding completely
* The configuration is nowhere close to the final, and will be changed, perhaps rather dramatically, including the shape of a duct
* The radar blocker will be installed into the intake, which is NOT the fan-like contraption we often see, but a 3D coaxial labyrinth
* The radar blocker is already designed and produced, but now is installed only on T-50-KNS, and is absent on the T-50-1
* The radar blocker significantly alters the airflow in the inlet duct and current engines on T-50-1 aren't optimized for it => power drop
* That's why it isn't installed on the airworthy prototype, which suggests that it still uses older 117S engines

Their is a reason why I call you indians "pathological liars, and deluded" and at the moment you are doing quite a good job at it.

Whats this? These are prototypes. Does that ring any bell? oh oh wait. YF-23 YF-22 and X-32 got rejected? why? they did not meet USAF,N,M requirements because these fan blades compromised their stealth capability and this is one of many reasons. Thats why F-35 was chosen over "X-32" with "DSI" that hides the entire fan blade completely.

This is F-22 radar blocker in air inlets.
Notice: no fan blades are exposed.

And these are 4.5 generation radar blockers.

Even a 4th generation fighter has its entire fan blade hiden.

You are wrong there mate. YF-23 had better stealth capability than any other aircraft. But it was rejected due to reasons that it was not as agile and fast as F22.

You are spraying an AK-47 in a smoke cloud dude. Your analysis is FLAWED. Even your figures are wrong.

Admit it, you know nothing about any 5th gen plane. Its just hear-say that you keep repeating to please yourself.

 

[amoverlord]

New Paint job. \"5 star\".

Almost the entire compressor blade is exposed on both sides.

can\'t see any pic.......
