holocaust bloopers posted:I swear McD couldn't recreate that in the sim. It's the same thing with other oddball incidents and accidents which involved structural failure or loss of flight controls such as UAL232, JAL123 and ELY1862. When loading all available data into the box and letting other crew have a go at the same scenario nobody manages to get as far as the flight crew who was actually at the controls at the time, even with the benefit of hindsight. Sims, be it civil, military or engineering/scientific tend to be limited in that way, especially where it concerns asymmetric flight other than a fairly simple loss of thrust from one or two engines with no other effects. There is simply no flight test data available that would be detailed enough for this.

Having worked around aircraft structures, I have a bigger problem with this concept now than I did before. At least on the wings you have something to hang it from that connects to the keel and CG is low. What do they do with that engine? Hang it from STR0 and hope for the best?

slidebite posted:We did this a little over a year ago. We were staying in Arlington/Crystal City and really, for the price of renting a car for 1 day it was nothing compared to farting around with transit or paying $$$ for cab rides. Besides, it's handy to have the vehicle in case there is something else you want to do while you have it. Yeah I live in Fairfax and I think a lot of people who visit the area especially from Europe just aren't used to the kind of distances involved here. Dulles is like 30 miles from DC, seriously you want to rent a god drat car. Also you can visit the civil war battlefields in VA if you have one, which are pretty cool, but likely not of a ton of interest to people not from the US. e: you could possibly save money staying in Tysons actually and taking the newly-opened silver line at the beginning and end of the day if you're going into Washington, then just driving around in a rental car to see the stuff in Virginia. Could also stay in Vienna or Fairfax and take the Orange Line but I think there are more hotels in the Tysons area. I have no idea what hotel prices are like though cause obviously I have no need to stay in them. Mortabis fucked around with this message at 02:54 on Dec 14, 2014 |

30 miles isn't poo poo to me but I'm used to transit Still, if you can't or don't want to rent a car, expect a long trip out. If you can, it's definitely the best way to get to Dulles. We drove from Dupont Circle last time I went and it was fine all the way out and back, so I normally agree that a car is the best. Just this time I'm not renting one so I'll find out how the Silver/983 route works. also if we're reposting all our Udvar-Hazy links, mine is easy - my first post in the thread. http://forums.somethingawful.com/showthread.php?threadid=3276654&pagenumber=391&perpage=40#post421823408

The reason why americans are laughing is that if you're going to a rural airport you can end up in a Beech 1900. Moderate sized cities are often served exclusively by ERJ-135s or CRJ-200s. In the US ERJ-175s are often used on routes approaching 3 hours long, they're actually quite nice compared to the 50 seats or less regionals.

Why does the CG have anything to do with it? And keel? The 747 fuselage is mostly a stressed skin structure, so it's just a question of not overloading any one point on the skin. Even the wings are stressed skin structures.. but they do have spars in them, which is where things like the engine hardpoints attach to. None of that really relates to the height of the CG in relation to the airframe. I'll bet that stub wing has a lot of structure bolted to the inside of the top deck there. Potentially even linking to the decking hardpoints for the upper floor. But... that's just a wild guess. The only wacky thing I can see with it, is the slight asymmetrical thrust.

None of that really relates to the height of the CG in relation to the airframe. Well, maybe it's because I only work on '37s, but the engine is a really, really loving heavy piece of equipment in comparison to the rest of the aircraft structure. As you said, the engine is hung from the nacelle which is hung from the wing spar which in turn crosses through the keel and is balanced by a similar engine on the other side. What I mean is that you can't just go hanging the engine willy-nilly off of anything you please. Again, I only have the model of the '37's floor beams to go off of, but I don't see anything in there NEARLY bulky enough to support the weight of an engine. The only way I can see it working is if they hung a massive spar from the keel beam up to the top of the fuselage, but then the added weight of the spar, to say nothing of the engine, would make that 747 the most nose-heavy aircraft ever conceived by the human mind. Maybe they stuck a bunch of iron weights or 'passengers of size' in the back or something.

Compare it to the 747 SCA. The cabin shell structure was heavily modified to carry the added load of the shuttle from the mounting points which carry most of the shuttle's weight, to the 747's center wing box and main landing gear without any changes visible from the outside.

Okay, that's just a beautiful mod in general. Must get cold as gently caress back there in flight. Presumably they're not giving rides to anything but the shuttle though.

Setting aside the “how”, why would the test engine be mounted like that? Why can’t one of the existing underwing pylons be adapted? Surely a 747 can safely operate with three full‐size engines while lightly loaded.

As far as that side mount engine test bed is concerned, that configuration isn't new at all. On the north side of Sky Harbor airport in Phoenix, Allied Signal/Garret/Air Research/Honeywell (whatever they were called historically and/or are named today) had a Boeing 720 (I always thought it was a 707 to be honest) with a fifth engine mount on the side near the nose for as long as I can remember, well back into the 70's. It was semi-recently replaced with a 757.Boomerjinks posted:Model 777 made entirely out of manilla folders That dude is certifiably insane; people call me nuts because I make wooden model ships that take months to build.

Only barely AI related but I wanted to share somewhere?quote:Reminds me of a story my friend told me a while back. He was a pilot for American Airlines and was flying for their regional affiliate American Eagle. One day while in the cockpit waiting to take off, him and the other pilot could hear an argument happening with the flight attendant and a passenger. Often when a passenger is very upset the flight attendant will ask for the help of a pilot to calm down the upset person. Today I learned that seatbelt extenders are a thing and have the airport's code on them

That's a really unfortunate airport code in this circumstance, yeah. I always thought extenders were carried on the aircraft, since they have to weigh like, 0.02 ounces. They'd just stuff one or two in a compartment somewhere, probably next to the safety information props. I also just learned the FAA banned bringing your own in 2012.
