Stealth Engine Advances
Revealed in JSF Designs
DAVID A. FULGHUM/ORLANDO, FLA. and WASHINGTON

When Boeing revealed its full-scale JSF mockup at England’s Farnborough air show last summer, most observers were shocked to see what appeared to be the engine face placed a few feet behind the opening of the air intake. One of the basic rules of stealth design is that you find a way to keep radar beams from striking the rotating parts of an engine. Engine faces traditionally produce large, sometimes amplified, and distinct radar reflections that can be analyzed to identify the engine and aircraft.

In a clever use of technology (a technique considered a proprietary secret by the two companies), Boeing and Pratt & Whitney worked together to add stealth to the inlet guide vanes to mask the fan blades behind them. The inlet vanes are variable and open to provide maximum air to the engine in vertical flight, but close to minimize radar reflections during flight at operational altitudes.

…sounds familiar.

The problem comes that in this forum you have to deals with characters like Otaku and lots of other fanboys who RESPOND is rather ridiculous, insulting and childish manner to any sort of reasonable observations here.

Here’s a reasonable observation: that beloved bulge your clutching to, is where the wheel retracts into (ironically where you started this flame war 2 months ago), that large circular hole on the outside, remember? -it does exist- I didn’t photoshop the image- meaning that ‘device’ is much further forward than you’re trying to brainwash people here into believing

…and it gets worse (for a Russophobe like you that is) the curve of that bulge goes all the way round and develops into an oval-type shape which would shield ~90% of the real comp. face further back (it’s simple geometry & perspective). The 117 is not banana shaped.

There is nothing “ridiculous, insulting and childish” in accusing you of being an intellectually compromised and fraudulent troll- until proven otherwise. You’ve said yourself you’re “not an expert”, so why why don’t you leave it to the many hundreds of eminent scientists & engineers that are working on this project to come up with a solution.

They edge aligned the FR probe doors…..but left the c.-face exposed :rolleyes: Get a grip of yourself…..or kindly refrain from flaming.

Your antics would make Curveball wince.

Yup, but the fundamental difference with the T-50’s blocker is that because it is so ‘deep/long’ (also non-metallic and RAM treated) you won’t see the comp.blades from any angle, unlike with the Super-Hornet’s.

Also, I still believe ~90% of the comp.face is hidden anyways, the ducts may not bend as aggressively as the YF-23’s- but the principle is the same. They’re using multiple solutions.

A friend will be presenting our updated & painstakingly re-evaluated rendition shortly (you’re gonna love this)……;)

Also, where the hell is the fan behind the ladder? You can BARELY see it. . .

Behind the ladder, it changes back into the R-blocker airflow simulator;).

You’ve heard the saying ‘so bad it’s actually quite good!!’, I wonder if you can have ‘so wrong- actually quite right’? -Naah, I don’t think so…

Oh, come on Amiga, give the guy a break will ya. He’s running out of straws to clutch…

B. Sweetman’s retort to the Donley/North Show:

And had you started thinking about this kind of design in the late 1990s, and if “eating F-35s for breakfast” was on the requirements list, you’d end up with something like T-50. So I’d suggest that writing it off as a me-too F-22 is a bit premature.

That doesn’t mean that it is though, and from the looks of it I suspect that it’s not(especially considering the Russians are even conceding that).

You don’t think that 16-and-a-half ‘S’ ducts will put the PAK-FA in the F-22 RCS ball-palk?……you’re right it must be that IRST with its B-52 signature.
Speaking of which, did they cannibalise the B-52 for the F-22’s tail-fins? :confused:

overG, dooo sooomething!!!

At the T-50-1 is not installed radar-blocker, it will be installed on the T-50-3.

…so, it’s the airflow simulator for this……

…definitely maybe ;).

Question. What’s the likelihood that that curvature/contour (indicated by arrows) goes all the way round and forms a sort of ‘distorted oval’?

High probability?

If so, only around 1/2 of the radar-blocker face (positioned inside the ‘duct’) will be visible and, more importantly, next to zilch of the compressor face ;).
