F-84 Thunder Jet and Thunder Flash Ideas

[Chris707]

You could combine some real-world and planned concepts  - the XF-91 radar nose with the proposed two-seat Thunderstreak version (US Secret Projects- Fighters) and the RF-84K tail to provide a missile-capable FICON type. The USAF of the time would favor the Falcon, but Sidewinder would be no problem I'd think - AIM-9 was available early on, and F-84Fs were around until the early 1970s.

Thinking about it, with all the extra weight, you'd probably have to base it on the J73-engined YF-84J...

The second (51-1345) and third (51-1828) YF-84F prototypes were completed with wing-root intakes and a solid nose, number three was then converted into the prototype YRF-84F. The intent was that the solid nose could mount a heavier armament or an air-to-air radar.

Note the F-84E type canopies in the photo.

There was also a XF-91 proposal with the radar nose and NACA intakes. While they don't handle large airflows very well, they certainly look cool!

Does anyone do a YF-84J conversion?

[Ian the Kiwi Herder]

I had an idea about doing an F-84F in RAF markings, under the premise that in the 50's the USA would only fund NATO nations (MDAP?) if they bought US products (shame on them). If that was the case what colour schemes would you suggest, and if it was fitted with British equipment (MB seat etc), what weapons would it carry?

Hmmmmm, dunno where I heard this before.....

got to wondering what it would look like if you took an RF-84F and converted it to a radar nosed version?

So maybe a F-84 equivalent to the F-86 Sabre Dog - I like it!

It would probably look somewhat like the XF-91B.

Nah, I like the idea of the wing root scoops and full nose like the YF jon showed.

Spot on.

I'd never seen these before.  I knew they tested the XF-91 in different configurations, but didn't know the V-tail was one of them.

Does anyone know what the sweep angles of the leading and trailing edges of the XF-981 were, and what were the corresponding figures for the F-84?

[Jschmus]

Per Wikipedia, the F-84F has a leading edge sweep of 38.5 degrees, with an anhedral of 3.5 degrees.  There's no info on the trailing edge.  I found lineart of the XF-91 on the NASA Dryden website, and if I can find a protractor, I'll get back to you with the measurements.  Or, I could just post the link:

[Weaver]

That's okay Jschmus, you beat me to it: I've just found some drawings and I've been comparing them, superimposed.

The XF-91 has less LE sweep than the F-84 but more TE sweep. I was wondering if you could approximate the XF-91 wing by inserting a triangular wedge in the F-84 wing, but since the trailing edge sweep has to change, you end up having to fill and re-scribe all the control panel lines too. Another approach might be to join the back half of a more-swept wing with the front half of a less swept one, but what are the chances of finding two with the same thickness?

... or one simply builds the old, multiply re-released, Lindbergh 1/48th kit. 

Maintrack did a 1/72 vac, so one could hunt for it at shows etc.

[Weaver]

Ah, but I don't do 48th, and anyway, that kit isn't very common over here nowadays. I do remember standing looking at it in Riley's toy shop in Stockport, agonising over whether to buy it or not and eventually deciding not to, but I was about 12 at the time......

I don't neccessarily need an accurate XF-91 kit as such, just a way of approximating it so that I can do a PW aircraft that I profiled. It would be nice if it wasn't overly difficult though, since there exists the possibility of doing several models in different colour schemes.

[famvburg]

    Planet Models makes, or made, a resin 1/72 one as well.
