bitcoin bastard posted:tbh id be surprised if there isnt already some sort of auto fire mode where as soon as you put the nose in the correct place relative to the target you just marked, your already spun up gatling gun spits out a burst Doesn't the spinning of a Gatling gun also load and fire it?

well okay then, leave the already spun up part out, main question still stands e: also why the christ would you stand anywhere near where a gatling gun was pointed if theres ammo even remotely nearby? goatsestretchgoals fucked around with this message at 01:18 on Jul 25, 2015 |

TheFluff posted:On the JA 37 (fighter version of the Viggen) there was an aim assist mode where the autopilot would take over and aim the gun at the radar-locked target for you, but only in two axes - it'd show you on the HUD what you needed to do in the third axis, and then you only needed to pull the trigger. I don't know if it was actually a good idea or not though because as far as I know the Gripen doesn't have it. The Gripen has the automatic gun system as well.

chitoryu12 posted:Doesn't the spinning of a Gatling gun also load and fire it? For most aircraft rotary cannons, spinning the barrels actuates the feed/load/extract mechanism. The firing step is actually electrical so it instantly stops firing when the pilot lets off the trigger. However, the gun has momentum and will generally keep feeding and extracting live rounds for a short period (something like 6-10 if I recall, depending on the gun). The ammo systems on modern aircraft are a linkless continuous loop, so all the cases and unfired rounds end up back in the ammo box. If you could lay it all out, you could count the number of times the pilot pulled the trigger by looking for those extra rounds. I'm not sure, but it seems like the f-35 gun may back feed to make those normally lost rounds available. If you watch the vid closely you can see it reverse direction after firing.

Could someone do a brief history/system explanation post of the CCIP bomb sight? All I know from Jane's USAF (hell, going back to Microprose Strike Eagle for Commodore 64 I think) is that it's a pipper hanging from a "string" that indicates the fall path of the weapon and the projected impact point based on the platform's speed and altitude. Who came up with it, and when? Is it a western thing, or do WP and descendant aircraft use it too? Are/were there competing alternative systems? Finally, if you're approaching a target on a ridge or hill a few hundred feet higher than the ground that's under you right now, is it smart enough to use some kind of radar to adjust itself accordingly, or does it assume that you're flying over a flat plane and rely on the pilot to adjust for the target's altitude? PGMs make the last question somewhat moot, but I would imagine that development and training don't assume that you'll always have PGMs. Thanks!

Pretty unrealistic because it's a complex solution to a dumb problem, but an interesting thought since if refined it takes out any elements of pilot error due to adrenaline or whatever. Various Russian guns have flexible mounts, but they're only used in gun pods for ground attack purposes. The SPPU-22 allows elevation adjustment and the SPPU-6/SPPU-687 (that's the one that the GSh-30-1 can go in) add a little bit of traverse in the mix. To my knowledge, the Russians never bothered giving fixed-wing aircraft cannons flexible mounts for air-to-air purposes because rounds fired at non-trivial angles of attack weren't accurate and the trouble of actually installing and maintaining such a system wasn't worth any benefit it would have given them. They've been all about HOBS heaters for up-close-and-personal fights since the 80s, although the R-73M is ancient by today's standards.

They did some fairly serious work trying to fit a limited traverse system for the gun in the SU-27, PPU-27 with 5° traverse and 0-15°elevation. http://www.quarryhs.co.uk/Su27gun.htm

I'd imagine it's easier to do on an autocannon versus a Gatling design.

TCD posted:Eh, well, they must have worked out something as the barrel is still spinning and ammo looks to be moving after firing has stopped. Firing is electronic. Rounds are still loaded and ejected, but on some systems (I think someone mentioned the GAU-8 is one) the unfired ammo is collected separately while on others the unfired rounds just collect with the empties. Most or all M61A1 systems are the latter.

The avenger is closed loop, and if you don't pull the trigger for a little while it'll scoot unfired rounds back through the gun to the feed side.

I read somewhere that that sub may either be that one they were looking for not long ago or possibly some sub that sank in the area in 1913. While this sounds like bullshit, what ruskie sub sunk in 1913? A quick Google search yielded nothing for me.

The company behind this finding, Ocean X, is just acting so embarrassingly. They were this time trying to pretend that they had no idea which year this sub was from even though they must've known that from the start. Just compare the pictures they've released with what can be seen at: http://survincity.com/2013/10/submarines-catfish/ ... There are visible goddamn rivets on their new pictures, who'd use that when building a U-boat today? Why is the shape of the U-boat so far away from how a modern boat looks? Ridiculous.

And while we're on the topic of nautical nonsense, what’s behind Beijing’s drive to control the South China Sea?My favorite part posted:“Time immemorial” is a favourite official expression for explaining the duration of its claims to them, but as I looked at these old maps, I noticed that despite being written entirely in Chinese, the names of the islands were all phoneticised versions of the names westerners had given them in the 18th and 19th centuries.

Well, if its on AWACS duty it can just home in on the radar until they cut and run, which is what you wanted anyway. Not sure about how it would work on tankers.
