My CAD skills are fading away as free time, but I wonder if someone with CAD skills will finally start NATF-22 3-view?
At least we have something to start with.

Would a simple vector graphic be sufficient, or do you need a CAD file for, say, building it via
a 3D-printer ?
 
Jens, just a 3-view...
 
Then let's have a try ...
 
I'm trying my hand at it.

Others can probably improve on what I've done so far, but I plan on doing a front view as well. At least we know the top view should be accurate.

EDIT: I just noticed that I forgot the wing control surfaces...

EDIT 2: Finished.

Well done !
When I was having a day off at the climbing crag with my family and having a barbecue, you
was working hard ! ;)
Just a clue: Judging the model, the inlets are a bit more rounded on the model and the lower line
of the cockpit tranparency seems to be a more straight line.

Have checked out again the pictures we have so far and came to the conclusions, that three different
interpretations of what it would look like are shown.

- The top view is based very closely indeed on the F/A-22. Kryptid has shown perfectly, what this
proposal would look like.

- The artists impression shows a much different bird. Apart from a generally sleeker look and the cockpit,
which seems to be more straked in, the most important difference is the additional kink in the line between
the intake/fuselage junction and wing. For myself, I took this picture as mainly "art".

- The third layout we know is the model. As we have TWO pictures of it, I decided to use this one as my
primary source.
As already pointed out, the cockpit looks different to a "standard" Raptor. After closer inspection, I think,
that this aircraft is longer, than the F/A-22, with a deeper fuselage, that after the cockpit section tapers
into a more angular cross section, indicated by a curvature on the model.
Would like to get some feedback, before adding more detail, as there's not much sense to be barking up
the wrong tree. :-\

Zillion thanks, guys!
 
To my calculation, the NATF would be at least the length of the F-14, probably around 20m.
Is thath realistic. I would like to add some details, are there more pics of that model around?
Maybe in higher res ? And is my assumption about the changes to the fuselage plausible at all ?

Not quite. The details of the top view and the model looks much more like a YF-22 derivative so I don't you should be using production F-22 as your reference since the design for that wasn't finalized at the time NATF was still an active proposal.

Good clue, that brings the intakes more in line with NATF topview, the fins are smaller and moved
further aft. The cockpit position nevertheless is more forward, maybe to improve visibility during
carrier approach ?

Jens, check the mail.
please note that you missed cropped lower edge of vertical rudder (just in case).


P.S. Aircraft at drawing looks much sleeker than model I'd say

Yes, you're right, I think, the shape of the nose should closer to the top view/YF-22,
will change this.

Nope, I think not, but it's covert by the wings, for which I've used no di-/anhedral.

I'd believe model _more_ than artist's impression though
 
Me too, that's why I took it as basis .
Not to get it wrong, with "too slim" you were speaking about the nose section ?

Have finished this "project" for now, as long, as nobody comes up with critics, errors, corrections, etc. ...
- As mentioned in my last post, I somewhat corrected the horizontal shape of the nose and did
some minor work on the shape, e.g. of the fin/tailplane support. A little bit buggering with the photos
of the model, brought some structures to light, that I interpreted as panel/weapons bay and hinge lines.
Ok, I admit, in some cases, they may just have been dust on the photographers lense or maybe I was
temporarily cross-eyed....
Be that as it may, in the "basic" drawing, only details can be found, that to my opinion actually are
shown on the model.
In the "supplemented" drawing, I added some details, that the real thing quite probably would have, but
that aren't recognisable on the model, like landing gear, hook, weapons bay (underside) and wings swept
forward. As pattern, I used the drawing of the YF-22 supported by Flateric and drawings/photos of the
F/A-18 (nose wheel).
Clues and critics welcome and, of course, additional photos of that model !

Tried to add some colour to this "grey ghost" . Paint scheme mainly based on the model photos,
but "enriched" with some more, absolutely fictional details. Not for purist or number crunchers ! ;)

Very nice!! But don't forget that "Gray Ghost" was actually the name of one of the YF-23 competitors!

That's why I used the English spelling ! ;)

As a reminder only the gray-colored YF-23 was nicknamed Gray Ghost, the black-colored YF-23 was nicknamed Black Widow II. -SP
