F-108!

[Stratos]

Discovered this beauty in another forum so I needed to ask permission to post it here. Maybe someone will like this plane as must as I do and can create it for SF series??

 

[Gunrunner]

Except this is not a F-108... That (http://en.wikipedia.org/wiki/XF-108_Rapier) is a F-108 !

 

What you have is more like the bastard child of a F-104 and a F8U, giving something remarkably similar to a Mirage F1, just a little less gracious.

[+aleks]

it seems more like the x 27 lancer....but in some details is different!!!

[Gunrunner]

Nope, nothing like a CL-1200, neither like a XF8U-3, it's a combination of a F8U and a F-104 three view plans.

 

And it seems like a horrible intake design, the flow being perturbed by both the cones AND the wings leading edge ?

 

You can't put loads on chins like in the F8U, but you don't have the whole span of the wings either because of the bulge of intakes and the folding (and variable incidence...) wings ?

You can't put centerline loads either because of the low ground clearance and landing gear inherited from the F8U...

 

Folding wings, naval design ? But no hook and a rather limited forward view due to the long nose ?

 

Transonic area rule ? Never heard of it, with this intake position, the fuselage cross-section is near it's highest exactly where it should be at its lowest...

 

That thing is a heresy ^^

F-108 Rapier

 

 

 

The 2 different proposals

 

 

 

F-109

 

The "Missing link" of the century series-as well as the Phantom II was early defined as F-110A-

 

 

[+76.IAP-Blackbird]

What was the rapier, a interceptor? Looks like a escort for the XB-70

[+X RAY]

Both!Was a big faster heavy interceptor with Ethilborane propelled jets for escorting Valkyries and I think in normal ADC duties

[+76.IAP-Blackbird]

wasn`t a valkyre in the pipe a long time ago?!

[Anthony W.]

I've only had dreams on a Valkyrie for TW... Oh wow... What a bird...

[Stratos]

OOOPS I called F108 cause is a mix of a F104 and a F8, know nothing about a real F108. I posted here cause is a "scifi" plane. Don't need to be able to fly to really fly in SF world

[Gunrunner]

Then call it F-112, except that, IIRC, the YF-112 (and following) were used for soviet aircrafts used for evaluation.

 

Nevertheless, whatever its designation and how cool it looks, it doesn't seem aerodynamically sound, or a practical configuration... but that's just my amateurish 2 cents.

From Globalsecurity.org:

 

YF-110 = Mig-21

YF-113 = Mig-23

[TX3RN0BILL]

That F-109 looks awfully similar to the german Vertikaljäger VJ-101...

[FastCargo]

I honestly wish folks would do a bit of research before posting stuff like this. A 2 minute google would have told you the F-108 had already existed at some point...even if it was no farther along than a mockup.

 

Secondly, the F-108 didn't go through 2 proposals. The design constantly evolved as the requirements changed and a better handle on the technology was gained. Hell, it even went through more changes AFTER it was cancelled...a design North American released in 1960 looked almost like something you'd see in an anime...with huge LERXs, large folding ventral fins, etc.

 

There are several books and articles which detail the requirement, evolution, and cancellation of the F-108...most of them about the XB-70. About the only thing I haven't seen in any of the articles is a decent picture of the rear of the aircraft. The USAF and NA had even proposed having thrust reversers instead of drag chutes...

 

Though there never was an aircraft, the development of the weapon system contributed significantly to what would eventually become the AIM-54 Phoenix. Also, if you want to get an idea of just how large and what the layout of the aircraft would have been (minus the cranked arrow wing), take a close look at the A-5 Vigilante.

Whatabout Canada's indigenous Century-series intercepter, the Avro CF-105 Arrow?

 

 

There's a huge cult following for this sucker, us Canadians really think we had a winner here. Fly-by-wire and Mach 2+ in 1959, you know.

[FastCargo]

The Arrow is a nice plane...but folks were already flying Mach 2+ with just one engine by that point.

 

The FBW on the other hand was significant...though rudimentary.

 

Now, no more thread hijacking.

Hey, I like the Mirage F1, so maybe someday I'll play with this, heeding Gunrunner's advice of course. Plus you could probably just throw an F-104 pit in it.

The Arrow is a work in progress from Blackfly flight productions, they specialize in Canadian aircraft and objects for the wings over series; and all of their stuff looks amazing.

And a peek at what the F-108 was supposed to look like:

Not bad, not much into the Century series aircraft but can say this one looks allright

[+GrinchWSLG]

Its now the F-112. That I'm willing to change. It also needs a name.

 

 

The design for the most part however, is now not going to change. I'm lazy. Deal with it.

 

I did consult my old roommate and good friend who's an aeronautical engineer in the industry. He recommended extending the intakes, just as Gunrunner pointed out. The wing doesn't have variable-incidence, its fixed. The wings don't fold either. I approached it with the mentality that this would be a design meant to be exported to poorer countries, maybe to keep them from buying Soviet equipment. Therefore, its designed to be dirt cheap, no fancy features. You're lucky you get a radar and an ejection seat.

 

Anyway, that's my approach. Open(ish) to suggestions, but its my project now, muhahaha.

 

Release date: .......before the YF-19, that I can assure you.

Performance in the F-5 range, maybe slightly higher....?

[+GrinchWSLG]

Not sure yet. Still a ways from being in sim. I think I decided on the J57 to power the A model, with a possibility of a J75 in a later version, obviously with some modifications to the rear fuselage. But the J57 fits in there perfectly right now. Performance wise...well I think it'd be great if it turned out mediocre all around, heh heh.

 

I'll start crunching numbers and looking at data once I'm done with the model.

[Gunrunner]

Another hunch (hey, I'm no aeronautic engineer), since you removed the dog-tooth from the wing, the variable incidence is gone, the intakes are moved and you apparently diminished the anhedral of the wing, I'd suggest that the stabs now have no good reason left to be dihedral, in fact, in addition with the large and tailfin I'd be willing to bet the present configuration is more subject to yaw-roll coupling than the original design.

 

I'd also add ventral fin(s) to help yaw stability (most planes of such a configuration had fins or quickly adopted them).

 

If you're going for a dirt cheap plane, you could also remove the avionics hump inherited from the bullpup-capable Crusader.

It couldn't be used to store enough fuel to be interesting, and the lack of need for advanced avionics in such a cheap plane would not justify the presence of spare space.

 

Oh dear, next I'll suggest a smaller tailfin, a moving intake cone and an angled landing gear to improve the ability to use centerline plyons, and we'll end up with a Mirage F1, except you could have your plane up in the air in the early 60's, whereas the Mirage entered service in the early 70's.

[Stratos]

Looking great man!! Your idea about poor countries just fit perfectly, a really cheap interceptor!!
