OptimusMatrix posted:I've never heard about this. Got anymore info on it? Ditto, I remember reading up on the relatively frequent updating markings/stripes/camo on aircraft to reduce the risk from captured aircraft, but not that. Makes sense though, little to no aerial radar, nevertheless IFF, but I wonder what course they'd send the bomber on to slip past escorts and kinda slide into formation. Though...what Allied bomber bases operating B-17/24/25s were overrun with aircraft captured intact? I feel like there's a huge gap in my WWII knowledge, I can't think of one right now.

VikingSkull posted:Plenty of them made forced landings in Germany. I have books that talk about the Germans using this strategy, but no scanner or the drive to browse 1,000 page tomes about WWII. They did do it, though. They got around the escorts by waiting until the escorts left. Fully escorted bombing missions weren't common until late in the war. Ahh, yeah, forced landings would be easy enough to repair and fly again. Not surprised about disguising/using captured land vehicles (would more surprised if that did not occur, heh). And I suppose before the P-51 came around, after the -47s and -38s would leave, I'm picturing this B-17 just dashing out from nowhere and joining the formation, "sup guys".

Can an AeroE explain winglets and friends real quick? From what I understand, it seems like those guys would combat wingtip vortices that form at speed. Would they also affect the aspect ratio of the wing? IIRC, wing AR is length:chord, so you'd get a slight increase in length of the wing without a huge amount of extra mass?

monkeytennis posted:Those 146's are tough little birds though... The first comment is amazing: quote:This comment has received too many negative votes hide Also, I just ordered this book after reading an excerpt from it in the September issue of Men's Journal. Russian cargo pilots own. There's this story about ISAF needing a generator flown into a remote operating area in Afghanistan, but no cargo charter will do it because it's contested, hostile territory and the plane won't be able to get back out. So these Russians call up, and say "hey, we'll do it for $2 million". ISAF has no choice, has to pay them. So these ex-Soviet Air Force pilots fly back through the Afghanistan of their youth and land this POS Il-76 right on the dot on the runway, dropping off the generator they need. The Americans are like "well, gently caress, how are they going to take off?" This bus rolls up, and the Russians hop on-board, ready to leave. They explain they bought the plane for half a mil, patched it up with tape and some rope, and intended to just abandon it on the airfield once the delivery was done. Net profit: $1.5 mil and immeasurable  e: here's the last quote straight from the article: quote:"The Yanks were all going, 'Hey, how will you get the plane back?' And the crew just said, 'We won't. It's an old one - we only bought it for this job, and we're ditching it here.' Half a million dollars it cost them. They held it together with string, just long enough to land, cleared $1.5 million in profit, and left it to rust. It's still there." and another: quote:The navigator's phone rang and an English-speaking voice sad simply: "Don't stop. Just drop the loving money." That was what they'd been waiting for. The strongbox and its attached parachute were already positioned; the loading ramp open. He cut the lines and $20 million was released into the sky." movax fucked around with this message at 05:44 on Oct 20, 2011 |

Is there a thread in BFC relating to bankruptcy (Chapter 11) and such specifically? Don't want to derail too much on finance, but if I understand correctly (great post Saga!) Chapter 11 Bankruptcy - Get out of jail "free" for corporations? - "We owed you money? Welp, too bad, suck it shitlords!" - "Pensions/Benefits? Went down with the ship, suck it shitlords!" - "Credit rating trashed? Good thing that was for our old corporate entity! Suck it shitlords!" - Get collectors off their back long enough while in protection to reorganize and stop bleeding money everywhere Or is there actually some accountability and this isn't just a reset button for a company? Also, it's giant companies like ILFC (ex-AIG I think? Udvar-Hazy's baby) that actually wrote the check to Boeing and "own" the physical aircraft, correct? The whole industry just seems ridiculous to me, infrastructure-as-industry just seems broken in its very nature to me.

Mig flies home with intact sidewinder in tailpipe which is reverse engineered and about a year later all soviet planes are flying with exact copies on their wings. Ahh, that's what it was. Was going to echo the request for the story, but now I remember reading about this. Didn't the Russians also slavishly copy ever rivet when they reversed the B-29? Also, they were a metric country, so they used the nearest gauge to the American materials and the copy ended up a good deal heavier, IIRC.

Aren't those the as gently caress? The camera angle makes it look even more awesome. 3 jets in that photo that I can see.If Russian pilots got the same amount of stick time as Western pilots, and the jets got similar MX, those would be downright scary to face in a dogfight. So goddamned maneuverable. Thinking up awesome ideas and then watching them get implemented by the West is the story of their lives though; if I recall correctly, a researcher at Lockheed stumbled across a Russian mathematician's paper and found it very applicable for a certain stealth project... Instead they mostly crash on their own or get shot down in wars because they're being flown by some poor bastard who's been up in the air for the third time that year.  I think India can afford to throw the money at their Su-30MKIs and pilots to keep them operational though (record of their Mig-21s aside...). I believe only 2 have crashed so far, one with a fatality.

Mr.Peabody posted:The general consensus there sucks. If I owned 3 radio towers I could make a military drone fly off course, and I'm not an electronic warfare agency of a government. All you need is the known coordinates of 3 satellites, their broadcast frequency, and the ability to delay and rebroadcast their signal from multiple ground sources. A simple delay can trick the GPS into thinking it's 500 miles West of its actual location, and cause it to suddenly veer to the East. It would think it is correcting its position or returning to base, when in fact it is flying deeper into Iran. GiP think because the signal is encrypted it is impossible to crack, but they don't need to crack it, just slow it down. They think Iran is too stupid to hack it, but it's not complicated and it's not even innovative. All it took was a few minutes on google to find a research white-paper on the vulnerabilities of military GPS receivers. Now imagine if you are a government with an electronic warfare agency, access to a hundred radio towers, a serious interest in recovering a remote controlled spy plane, and daily opportunities to do so. So you have to acknowledge the vulnerability exists and there is continual access to exploit that vulnerability. Every day the probability that they will exploit it approaches 1. It's definitely possible to do, and I've seen it done...on civilian GPS receivers. Remember that military receivers can decrypt P(Y) (accuracy improvement) starting with PPS-SM in the mid 1990s, and currently on SAASM (the uDAGR I've linked below implements SAASM). It doesn't improve jam-resistance any though (same signal coming from space), though the new code they are rolling out on Block IIR/IIF promises to improve that aspect as well. What the P-code does prevent is an enemy transmitter mimicking a real GPS satellite and the P(Y) code. The GPS ASICs that Uncle Sam uses are rolled in-house; I think you're in for a world of hurt if you're caught with a Rockwell GPS ASIC in your pocket.  "Browns are dumb hurrr"/"GiP is dumb hurrrrr" aside though, it'd be dumb for an UAV like that to depend solely on GPS as a navigation system as iyaayas said, and it likely has a INS/IMU or similar system as well. Coupled with a large amount of sensor fusion fed into a control system, it'd be almost impossible for a UAV to not realize that it's GPS data if supposedly jammed/compromised is no longer valid. Every civilian UAV I've seen, even the most basic of homemade drone has some type of IMU in play feeding into a Kalman filter or similar. Some of us moronic civilians even go further and implement Schuler tuning in our INS. I think that article makes a good (and almost reasonable) story, and hopefully my faith in the competence of our fine engineers at Lockheed and friends is not mis-placed. Here is a public/non-classified description of RC's modern military GPS portable unit. e: SAASM - Selective Availability Anti-Spoofing Module DAGR - Defense Advanced GPS Receiver Selective Availability - a now defunct ability to introduce artificial navigation error in public navigation signals P(Y) - the "precision" code. Each satellite broadcasts several signals, originally just the public/open to all C/A coarse code and precision P code, but now expanded to new secure code (M code) and transmitting civilian signals on a new frequency as well. Currently there are: L1 - C/A, L1C Civilian Code, Military (M) Code, P(Y) L2 - L2C Civilian Code, Military (M) Code L3 - NUCLEAR LAUNCH DETECTED L4 - Nothing L5 - Safety of Life e2: "well what the gently caress do you know about GPS movax?" I researched under one of the engineers on the original NAVSTAR project, read several of the standard GPS texts from cover-to-cover and am currently home-building a GPS receiver, so I think I know a fair amount about it. Still all conjecture though. e3: jamming != spoofing, jamming should not have made the UAV "land safely in Iran", and if they successfully spoofed our military GPS signals, we are kinda boned. Jamming is me screaming "DICKS DICKS DICKS DICKS" so you can't hear what your friend is saying, spoofing is me intercepting your friend's words and replacing them with my own "LAND YOUR DICK IN MY BUTT" movax fucked around with this message at 17:58 on Dec 19, 2011 |

DJ Commie posted:Are you writing your own GPS code, or using a premade chip? What is your output? NMEA 0183 over serial is all I've used so far, and on a somewhat old USB GPS WAAS module. Using a pre-made chip is really easy with an Arduino or any other microcontroller, and is far more practical then what I'm doing, heh. I've used quite a few, from SirF to cheap-rear end Chinese ones integrated with GSM (SIM548 and similar). Mostly interfaced with over serial and NMEA 0183 format, as you said. I'm basing mine off this project and some Altera FPGAs I have laying around. That project in turn was build by an Eastern European guy who built his own receiver almost fifteen loving years ago out of discrete chips. This will be retarded expensive, but incredibly satisfying to build from scratch. I find it really cool to scratch build something that's usually limited to a giant corporation + semiconductor fab; high-speed stuff is really hard for the hobbyist/enthusiast to break into. I wonder if it'll violate ITAR because it lacks any speed/altitude restrictions
