Mid-Atlantic Air Museum up in Reading just had their WWII airshow this weekend. I skipped it, since I went last year and drinking beer was just a higher priority this time around. But your Stearman comment reminded me of this: They're in the process of restoring a P-61. It's a very long process, they started it back in the early 90s. But here's what the thing looked like when they went to haul it out of the New Guinea crash site: They were fortunate in that it crashed onto a pile of rocks, and wasn't directly in contact with the jungle floor. When they went to assess it, it still had air in the tires and hydraulic fluid in the lines, and corrosion was actually inhibited by the vegetation growth. Now, a while ago, the US government basically signed away any interest to any wrecked aircraft, and said that anything lost during the war was a spoil of war, owned by the country on whose soil it rests. So this aircraft belonged to Indonesia, and Indonesia wanted to get paid. Payment in this case took the form of a fully restored, flying PT-13 Stearman. MAAM's been offered $6 million for the P-61, and that was a couple years ago before they even had the engine nacelles on. They (rightly) said no. Here's a cow orker in his PT-19: And here's this thing:

grover posted:F-35 and V-22 don't require special pads for takeoff and landing, just for tests where they run the engines at full power for extended times, and that's fairly economical to address. There's a bit more to it than that, and it involves more than just running the engines at full power. Here's the RFP: DARPA posted:The deployment of the MV-22 Osprey has resulted in ship flight deck buckling that has been attributed to the excessive heat impact from engine exhaust plumes. Navy studies have indicated that repeated deck buckling will likely cause deck failure before planned ship life. With the upcoming deployment of the F-35B Short Take Off and Vertical Landing (STOVL) Joint Strike Fighter (JSF), it is anticipated that the engine exhaust plumes may have a more severe thermo-mechanical impact on the non-skid surface and flight deck structure of ships. Harriers routinely rip up the antiskid, but this is heating the deck enough for it to buckle. It's not just full-power run, it's even at idle; on Bataan it was happening in as little as 20 minutes. Interim fixes include heat-spreaders that need to be laid on the deck under the nacelle, and parking the aircraft with the engine you're going to run out over the water, but that latter's not always an option. DARPA's looking for more permanent solutions, especially for the F-35 which will be worse for the decks than the V-22 by a long ways.

The most amazing thing to my mind about that airplane's the goddamned air conditioning. We're sitting on an Indian air force base in Chandigarh, and the C-17 comes in delivering the Chinook we're going to demo for the IAF. They open the ramp and the guys go about unloading the whole thing, took a couple of hours. All while they're doing it there's just this solid stream of freezing air blasting out of the open ramp, you could have flown a kite with it. I almost felt bad about flying home BA business class while some of our maintenance guys had to ride the C-17 home and ended up stuck on the ground at Ramstein for something like 3 days because some German got a bug up his rear end about HAZMAT documentation for the extra hydraulic fluid they'd brought along. Almost.

Tsuru posted:Wasn't there at some point the idea to replace the BUFF's 8 engines with 4 bigger turbofans? It was originally an unsolicited proposal from Boeing to pull off the TF-33s and replace them with 4 RB211-535s (the ones on the 757). Range, speed, and fuel burn would all have been improved. Every once in a while it seems there's a new proposal, some of them just replace the 8 old engines with 8 new engines. PW2000, PW6000, CFM56-3 JT8D-200, and BR715 have all been suggested/considered, but they don't really go anywhere because of the point already made above: there are shitloads of spare TF-33s laying around. Godholio posted:That's come up many times. Sadly, the USAF has hundreds of TF-33s just waiting to be refurbed as necessary. Same reason AWACS and JSTARS will never get new engines. Too many spares available from old KC-135s, C-141s, B-52s, etc to justify the massive up front costs, even though the performance gains and maintenance and fuel savings will make up the difference down the road. That's not what GAO said. GAO said "Boeing claims this will save the government 4.7 billion dollars. We calculate that it will actually cost the government 1.6 billion dollars. So don't do it."

Every flight control system removes control from the pilots, by design. If you don't think there are FCS on Boeing commercial aircraft that do things for the pilots you are very, very, very wrong. You think the pilot is controlling every aspect of what the engines do on an aircraft with a FADEC? What do you think the 'FA' stands for in that system's name? It's true that Airbus institutionally designs FCS that don't allow the pilots to do some things that Boeing trusts them to do, but the entire *point* of modern FCS is to have the computers do things for the pilots. If you were flying an MH-47G during aerial refueling operations, you'd consider the DAFCS on the newer ones a good thing, especially in bad weather.

Ridge_Runner_5 posted:That is utterly terrifying. It sounds like Bonin's mind shut down and he didn't think enough to realize he needs to push forward. There's more to it than that. First, you should never ignore a stall warning. Second, they shouldn't have such rock-solid faith that the normal-mode FCS won't let the pilot stall the airplane that it honestly doesn't even occur to them that the warning's a legitimate alarm. Third, the notion of a stall warning if the FCS is in normal-mode and will actually prevent a stall doesn't make a whole lot of sense from the standpoint of user interface design: "Stall! *chirpchirpchirp* Stall! *chirpchirpchirp*" shouldn't mean "Hi there! This is just a friendly reminder that you're doing something really dumb with the stick, and the plane would be falling out of the sky right now if I hadn't overridden your control inputs. Have a nice day!" Fourth, the pilots should be *able* to stall the aircraft in normal law; they might not ever want to actually do so, but they should still have to consider "Will what I'm about to do cause a stall?" Fifth, nobody in that cockpit knew how the damned FCS worked, they didn't understand that, hey, without airspeed, they're not in normal law anymore, and *all kinds of lights* go on when you're in alternate law. Sixth, the lack of cross-feedback between the sidesticks, the fact that the guy in the right seat can be pulling the nose all the way the hell up and the left-seater doesn't even feel it; if there was any sort of link between the two, left-seat is going to notice right away that right-seat's pulling on his stick for all it's worth. Hell, on a plane with yokes, he'd have the yoke jammed into his stomach, which would be a clue (yes, it's really not tractable to mechanically-couple sidesticks in a reliable fashion the way you can with a conventional yoke or a center stick. You could implement an electrically-driven force-feedback system but that likely causes additional places for poo poo to break; this might be an indication that conventional control mechanisms are superior to sidesticks as a UI). I'm curious about how much time these guys had in-type, even the veteran with 11,000 hours who was taking a nap until a couple of minutes before the plane hit the ocean.
