Has anyone tried to put the Viggen wing on a Phantom? The canards probably wouldn't fit, so a conventional tail would most likely be retained.

Ummm, about that...

I was thinking the large canards from the Viggen would be a little on the large side - at least to look right. I don't think the Viggen wing would be easy to put in the rear of a Phantom, so it would have to go where the usual Phantom wing is.

The Viggen wing might be a little on the small side for the Phantom?

Picture based on SVG files found on Wikimedia. Tried to scale them about right (That Phantom is BIG)

Looks good

All the more reason to have the ~~canards~~ ginormous vortex generators too

Plus you would have to keep the conventional tail too to have enough of pitch authority. Don't think that Viggen canards would look too big since the wing already looks small. (Unless you go scale-o-rama and put 1/48 Viggen wing on a 1/72 'Toom).

Viggen canards on the Phantom intakes almost turn it into a biplane.

I posted images of this before but they vanished in the great photobucket debacle of '17 !

I’d suggest a dorsal intake for the third engine, XB-51 or Grognard style perhaps.
The path from a nose inlet would be a non-starter for structural and airflow reasons.

Like these?

elmayerle · « **Reply #309 on:** November 22, 2017, 11:36:40 AM »

You might need to move the upper intake forward a bit to get a reasonable "S"-duct to the center engine. Too short a distance and, while you can fabricate sheet metal to make the duct, you're going to get flow distortions from the tight bends that will cause engine performance problems. My thought would be to move it forward to just behind the refueling receptacle. Too, you might want to consider a F-107 style intake to better handle maneuvering airflows.

Beautiful camo scheme.

Some time ago elmayerle mentioned a study related with F4-EJ Kai. Here F15 wings will be used insted of originals. I was wandering to use some more F15 bits, such as cockpit and canopy, single or double post, enlarge tailfin, ...

What do you think?

ysi_maniac · « **Reply #313 on:** February 02, 2018, 12:31:00 PM »

More F-4EJ Kai (Eagle wing)

Jeffry Fontaine · « **Reply #314 on:** February 02, 2018, 02:43:08 PM »

Nice work Carlos! I have had plans to do just that to an F-4E on my list of what-if projects for a long time. The only real challenge is where to place the wing pylons as the current location is going to challenge the space taken up by the main landing gear.

ysi_maniac · « **Reply #315 on:** February 02, 2018, 05:43:37 PM »

Good point !

Well, in this case you can take advance of not bend marginal area. Even you can use the design of F-15 prototype and some other studies in order to have an additional AAM rail.

ysi_maniac · « **Reply #316 on:** February 14, 2018, 01:12:03 PM »

My current ideas about this modernization project:
- F-15 wings
- I think it is convinient to use F-15's tail plane for a matter of compatibility. Less canted than F-4's
- Minor tail fin mod, for aesthetic purposes
- A new less framed canopy, a little raised which allows to raise ejection seats
- Use of F-15 ejection seats?

What do you think?
Would you delete any of these mods?
Would you add any other mod?

finsrin · « **Reply #317 on:** February 14, 2018, 01:55:21 PM »

F-15 mods to F-4 fit so well. Ideal for a kit-bash.

elmayerle · « **Reply #318 on:** February 15, 2018, 03:21:47 AM »

Some of the last F-4s produced had frameless "blown" windscreens, so this isn't too far out at all.

^^^^^
Hi Evan, what do you think about using F-15 tail plane or F-15 ejection seats?

ysi_maniac · « **Reply #320 on:** February 15, 2018, 11:02:18 PM »

elmayerle · « **Reply #321 on:** February 16, 2018, 02:25:04 AM »

I don't see a problem with the first, offhand, and the second would likely introduce a better seat to the aircraft.

I have a thought for a single-seat variant going back to the original low canopy profile, fitting a blown windscreen, and using the F-15 wing, likely with the extra wingtip rails for Sidewinders and the like.

Stealth Phantom. Top drawing is 'presumably' scaleoramed from 1/100 to 1/72
