Your Nation's Air Force Mark II:

[Kassaran]

Alright guys, so here's the conversion. I think I'll keep the YKP-29vi Chassis for a Strike Bomber as suggested before, but I'm also making a Mark II for the Interceptor Variant...

Here's the comparison between the two, the top variant of the GRIFFIN being the Strike Bomber Variant and the bottom being the Interceptor Variant:

Pointing back to this though, anything anyone want to say on the two? I figure it'd be best if I made a definite build out of the two separate designs from the, like, fifteen hours of work I spent on them.

[Iltica]

The 29ii looks just about right. You might make the folding wingtips a bit bigger, but the XF-108 doesn't have them.
I don't have the facts to back this up but I suspect it used the ventral fins on the undersides of it's wings to the get the same effect, or maybe just by being smaller it could do it with smaller angles on the wingtips. They are still canted downwards noticeably.

The tricky part is that the compression on the B-70 isn't happening between the folding wingtips but between the wingtips and the fuselage which would seem to require a high-wing rather than a mid-wing.

On the other hand, this could all be BS and the XF-108 just didn't need the compression lift...

[Vancon]

There is a fine line between winglets, which are used to stop vortices, and folded wing tips which are used to save space on carriers.

Generally, only naval aviation variants of aircraft have that.

Kass, it looks good.

So I wanted to design my own stealth plane based on the SU-30, I tried taking elements from the F-22 and F-35, but in the end I feel like it came wrong looking.



Any suggestions?

I don't really see any "Raptor" or F-35 elements to it, it just looks like an Su-27 variant with some extra stuff drawn onto it.

No, that is awesome. Best Russian based concept I've seen in a long time.

change the inlet into DSI one. That'll add some RCS reduction measure, while keep adequate pressure recovery at supersonic speed.

...he just played with the aesthetics a bit, he didn't even add ANY significant signature reduction features. Which is a problem because the Flanker has a huge radar and infrared signature.

waitaminit... Did you do vector art or antialiased art? Wtf is this shit?

Yeah, I wanted to try something different recently. I got tired of my pixel art because it's not very good, and anti-aliasing can make things look great in my opinion.

I don't really see any "Raptor" or F-35 elements to it, it just looks like an Su-27 variant with some extra stuff drawn onto it.

It's mostly with the nose and the "spine", I didn't really make any major changes.

Thanks!

I tried changing it, did it come out alright? (See below, of course)

So here's the finished version, I guess. I don't know how it came out, to be honest. It's not my best work in my opinion, but it was a little fun to make.



And since it's based on the SU-30, I thought for NS I'd try making it in Russian aircraft camo:

The coloring and art look great as always, I just wouldn't call it a stealth fighter because as far as I can tell, it doesn't really have any true stealth features. It has DSIs but what about planform alignment of the wings and stabilizers? Internal weapon storage? Low-RCS engine nozzles? etc.



On a tangential note regarding DSIs and fixed-geometry inlets:

I've not been able to read anything on the matter, but do DSIs affect maximum speeds over Mach 2? I know the F-16 Block 30 with the test DSI reached Mach 2 without any incident, and the F-35 is expected to operate well below this speed, but does it have any effects on maximum speed? And does anyone have any information on the extent of their RCS reduction, ideally vs. the conventional diverter spacing used in the F-22?

I've also read that the use of fixed inlets on the F-22 for stealth purposes affects its maximum speed versus the F-15 with its variable-geometry intake ramps. I'm aware that the focus on stealth over raw speed and the addition of supercruise gives the F-22 a higher "useful" speed than the F-15, but to what extent does this affect maximum speed anyway? Discussions I've seen seem to swing back and forth between "it's slower than the F-15" and "the F119s overcome the issue through sheer brute thrust."

And lastly, not related to the intake question, I was considering replacing the notional F-15 clone I had previously used as my 4th generation fighter with something more like the F-14. Which is to say, swing-wing and introduced a few years earlier. It's supposed to be capable of carrier operations (mostly so that I don't have to write up another fighter) and fleet air defense with a separate variant for land use, but also be capable of general dogfighting with later upgrades to introduce ground attack and strike capability to make it multi-role. It also lets me avoid the whole HURR US CLONE thing since my light fighter is already an F-16 with strakes. Is there anything wrong with using an F-14-like aircraft for these roles, before I go charging off in that direction?

[Vancon]

Apart from saving space, swept wings doesn't really do much anymore. I much prefer straighter wings myself, but I'd recommend large Delta ish wings instead. The Delta configuration would be able to do all you stated and then some. Plus, if you wanted to have your wingspan shortened for planes, you could always have them fold in over themselves.

Well I thin the F-14 will be perfectly fine in those rolls. I'm just confused on how that gets you away from the HURR US CLONE issue.

Swing wings certainly improved performance before computer aided designs became available. Once computer aided design came around they may still allow slight increases in performance, but they have higher maintenance so those improvements probably aren't worth it.

We're talking about the early 1970s here, and the plane needs to be able to generate enough low-speed lift to enable carrier operations while still being capable of supersonic flight. That's why F-14 had them. This is why even the modern NATF concepts retained swing-wings.

Well I thin the F-14 will be perfectly fine in those rolls. I'm just confused on how that gets you away from the HURR US CLONE issue.

It means my air force structure is no longer literally an F-15 and F-16 clone, and unlike the US I don't plan to retire my F-14 clone in the early 2000s, so it will see more upgrades. The structure and background is somewhat different than how the USAF ended up doing things. The end result will probably not be a direct F-14 copy, which is why my question pertains more to the concept.

Swing wings certainly improved performance before computer aided designs became available. Once computer aided design came around they may still allow slight increases in performance, but they have higher maintenance so those improvements probably aren't worth it.

The latter part isn't very important; my fifth gen already has fixed wings.

[Spirit of Hope]

Then an F-14 alike should be fine.

[Vancon]

Then an F-14 alike should be fine.

Im in this boat too.

I feel like people should specify their tech level when they ask a question on here. It'd make life a lot simpler.

Delta would be excessively large to generate comparable lift. Variable geometry wings allow you to have high lift at low speeds without massive wing area.

Could you elaborate more or post a link?

I mentioned that it was supposed to be a replacement for the F-15 and instead introduced a few years earlier (like the F-14 was IRL vs. the F-15). I suppose I might have specified "retcon," but I thought I had indicated that this was supposed to be a swap-out, not a modern replacement.

[Auroya]

The shape of the trailing edge of the tails is interesting to say the least.

Does that kind of thing actually reduce RCS more than edge alignment?

[Gallia-]

That is planform alignment.

2 Fighter designs coming up. Apart from the lines that neeed cleaning up, any fatal flaws?

Personally, the right seems very Textron Scorpion to me. What's the intended role?
