You know, this has been bothering me for a while, and really started bothering me when I was flying one in Ace Combat a lot (shut up :mad: )

What is in the enormous penis long, hard shaft between the engines on every Flanker? Or the super huge one in the Su-34? I've heard anything from RWR to a full-up rear facing radar set and nobody seems to know for sure. Except, presumably, Sukhoi, but seriously. You'd think a huge dick pointing out the back of an aircraft would get more attention on the internet where these things are the foundation of stupid epeen debates on Youtube over which aircraft is better than which. All of one article I can find on the internet discusses it and calls it a tail stinger, for what that's worth, but no details on what's in the thing.



Seriously. Look at the size of that thing.

Found a couple pictures from some terrible forum I'd rather never speak of again.

Amusingly, they linked to Livejournal. I should've gone there first, it's the Russian source for everything. Have some sweet Sukhoi photos:

http://dmitrydreamer.livejournal.com/24772.html

There's something EM-transparent on the tip of the stinger and what look like vents (supposedly for the APU exhaust?) and chaff/flare dispensers on the bottom. The -34's chute pops from further up the fuselage, so what's in the stinger is clearly something else.

also some extreme internet grognards claim that it's even worse: There's the standard Su-34 stinger and then a modified, different version! Too many airplane dicks. (The theory is the modified one is for a jammer/ELINT/SEAD platform, a la EF-111 that can shoot back)

So apparently it does everything, indeed.

The -34 is probably the only ugly jet Sukhoi has produced since the Su-25 (which is ugly by design) and I can't think of one that is ugly (or at least, uglier than its contemporaries) beyond that, so I can cut them some slack on it.

Mr. Despair posted:

So sad that they pulled the canards from the production version of the -35 though.

According to my extremely detailed research on "the internet" which may have consisted of five, maybe six whole clicks, canards are apparently complete poo poo for low RCS, and thus are getting ditched by everyone. Except the Chinese J-20, because I guess they just don't care.

Not strictly true; the Eurofighter's FLCS automatically adjusts trim so the canards can be kept in a position that minimises their signature.

I'm not a Radar Master, but wouldn't this fail miserably if you had two+ sources trying to paint the Eurofighter?

Plus the geometry of canards just doesn't lend itself to super-low RCS. Like anything that's a tradeoff, though - if they provide enough benefit in other areas, then they aren't inherently bad for having a downside. Everything has a downside.

While we're talking Cold War, I suppose I could mention the source of a lot of the plutonium in all the various things that went bang.

http://en.wikipedia.org/wiki/B_Reactor


Hanford B Reactor, Exterior by notpsion, on Flickr

Hanford B Reactor is open to the public for guided tours from DOE and it is their hope to have it attain full museum status - that is, drive out in the middle of loving nowhere, WA (this was a design requirement from the Manhattan Project - gently caress nowheresville, USA, oh ps need a lot of water nearby) and go see it whenever. Right now, trying to get on any part of Hanford sans official approval would be ... unwise.

I've been twice and I apologize in advance for the photography - it's a bitch and a half to shoot in there. Both times I've been all :mad: at the tours not giving me enough time to set up and shoot for poo poo and there is so much in that building worth shooting photos of. I'm not going again until it's museum status so I can bring a tripod and take my time setting up something for the front reactor face; 2004 process tubes (1500 or so filled with the u-238 rods they bombarded into Pu-239) is staggering, especially the cooling system required to keep that stable - like 30,000+ gallons of water a minute shot through, front to back, in less than a second, and going from like 60F to about 200F that fast. And then dumped into a holding tank (ok so far) and then right back into the Columbia river.

:negative:


Front Face 01 by notpsion, on Flickr



So yeah, here's where Trinity and Fat Man's Pu-239 was created. Also, friggin' amazing engineering: They basically designed and built this sorta-kinda on the fly after the tiny test under the Chicago squash courts, in 14 months, and it worked for decades. The first time I went our tour guide was a guy who'd actually worked shifts at several of Hanford's reactors, including B. There's a lot of amateur-hour video that could use some editing up to really make the experience hammer home but when the guy talking to you in the control room where criticality was first achieved was saying "yeah, so I sat in this chair for like five years" it's :stare:

And of course, the most critical part of Hanford:

Pie Making Machine by notpsion, on Flickr

I was deeply disappointed this was not saved and placed in the B Reactor facility. They do have a remote-control robot, though.

Also - apparently there's an annual inspection from a bunch of Russians who take photos of the water intake pipes (which are all staked open, have been since 1968) to ensure nobody's secretly started up B Reactor - or secretly built the shitpot of support buildings which it would need to function, but ssh. Our tour guide indicated the US does this to several Russian decommissioned plants, too. Personally, I would love to see a bunch of stone-faced obviously KGB guys with Nikons or whatever snapping away at B Reactor. LOVE IT. Alas, those 'tours' don't get advertised.

This post owns. I live in Tennessee and I've never been to Oak Ridge. I should turn in my TFR credentials :(

It is seriously incredible how they went from what was practically a scale model to this thing, one try, and it worked. (I know about X-10, but look at the dates - it's not like they finished X-10 before starting B)

Also for anyone concerned about the Chicago pile, CP-1 had no cooling system and a single control rod. Oh and no radiation shielding. At all. Fermi was all "I was totally confident in my calculations, really, it was fine." Find a map of the University of Chicago and go :stare: for a while. Fermi, holy poo poo man.

What's worse - his math was wrong for B Reactor (didn't know about neutron poisoning) so only the insistence they Build It Bigger, God drat It meant B worked at all. The addition of 500 extra tubes, ordered by the officer in charge of the project meant they could overcome the xenon poisoning to reach stable criticality.


while we're at it, B Reactor scaled up like crazy. Originally specified to produce 250mW (it was never a power reactor, only a Pu-production one) they eventually jacked it up to a couple thousand, and just shot 70,000 gallons of water a minute through the cooling tubes instead. Overbuilt like hell, which - really - was probably a very good precedent for nuclear plants of any type! :v:

e: I'm not so fond of them using Hanford as a "let's dump all our lovely nuclear waste here" site, but it is somewhat comforting to know, having been there, that nobody is gonna go anywhere near that place without a reason. You have no idea how sad and desolate and boring surrounding area is until you go.

I actually read some stuff circa 2005? about a proposed change of the 105 in the back of the Spooky to a 120mm mortar. At first it made no sense to me, because I was thinking "mortars? What?" but then I actually read more about it and someone did some mapping of the recoil forces (the 105 is obscene) whereas the 120 would give PGM capability and more bang per shot for less recoil. No idea how practical it is, but it had some pretty neat pictures, therefore, is probably awesome. That's how it works, right? :v:

I might be missing something but as I understand it:
-mortars have more explosive for a given shot than artillery shells of the same size
-a field artillery gun designed to fire a shell seven miles is probably a little bit ridiculous in an AC-130, where the firing profile is basically "down."

I also read far more than I ever wanted to about what amounts to musical chairs with various 20, 25, 30, and 40mm mounts. Pick one already :mad:

Normally yes but mortar vs artillery isn't a 1:1 for shell weight. I actually cannot find a weight in a quick google for the HE version of the 105 shell used in the AC-130 (I assume most fired are HE, no idea for sure) but the M934 mortar rounds are ~30lbs each.

What is more or less true? That they only ever fired down? Armies haven't replaced all their field guns with mortars, why would it be any different for a plane?

I see on wiki that the 105mm has an effective range of 11 km on the ground, it must be substantially higher for the one in the plane, which means the plane could pound targets from beyond the range of most AA and cover a much wider area than if it only had mortars. Doesn't it already have lighter guns to hit closer targets?

I think what you're missing here is that the 105's range on the ground involves a significant ballistic arc. Spookys, so far as I know, fire in direct LOS. Basically straight shots from the plane down to the ground. In order for your range comparison to work, they'd have to bank the plane 45 degrees up to loft the shell out. They don't.

That's what I mean: The AC-130 is a direct fire support aircraft, so it shoots "down" -- from plane to ground, clear line of sight. Hence the whole potential upgrades for stand-off capability (Viper Strike, et al) because right now the AC-130 doesn't have it.

That's no different for a mortar though. The gun is still going to have more range and be able to cover a wider area.

"Range" isn't really relevant when you're starting four miles up. The only range you need is "gravity."

For any "range" beyond direct LOS this is why there have been multiple proposed PGM stand-off munitions for the AC-130, including guided mortar shells. The 105 doesn't provide it.
