Hahahahaha oh my god! British men in sheds, there is nothing like it. You can tell the spirit by the text in his blog. It basically goes "oh looks like a difficult job but we'll just have to crack on and get the job done" about something utterly insane. Wonderfully insane! Aeronautically insane!

He speaks about the "characteristic clack clack sound" of blade flappers, I suppose those are the ones that sound like a spun bearing when it winds down. Anyone know what they are and do?

When the engine is turning at low speed, the fan blades are fairly loose in the hub, causing them to rattle around in the hub. Adding to that, the mid-span "snubbers", which maintaining blade spacing in many engines, will rattle off their neighboring blades at low speeds.

The clearances aren't an issue at normal engine speeds, as the fan blades will stretch enough that any of the tolerances in the hub will disappear. There are other things that can make noises like that in jet engines, such as sprag clutches on certain equipment, but they'd be more noticeable on smaller engines.

I figure he could sell it to a third world airline for some dollars, maybe build a mobile stand and take it around to fairs and stuff. Swap it into a 240sx. Lots of options really.

I'm curious about the long-term maintenance, stuff that requires major overhauls. What is his game plan there..

RB211 is still in use all over... 747-200, -300, -400 and the 757 all use it. Parts are pretty easy to find right now.

The RB-211 -524 and -535, yes, but not the -22. There isn't a whole lot in common between the -22 and any other engine in the RB-211 family. It would be like saying you could fix an LS3 with parts from Ed Cole's small-block prototype.

That said, you could buy -22s all day long for not much more than scrap price, as there really isn't any application for them today.

I always thought that "Jumbo-jet" was a sort of slangy/informal term for wide body airliners. I had always heard the 747 was the "original jumbo jet." Really though the 747SP is a caricature of a 747 anyway.

Originally, it referred to the the planes proposed for the competition that eventually led to the C-5. Boeing's proposal did not get picked, but they built the 474 alongside/out of that. Essentially, planes the next step larger and more efficient from the planes of the mid-60s.
The name stuck to the 474 very well, but has also been applied to the DC-10, L-1011, and A330/340.
Using a similarly rigorous procedure for standardizing definitions, the A380 has been called a 'super-jumbo' becasue its bigger than the 747

At some point it reaches "Anything bigger than a Comet", so I can't say I worry about it too much. But it's telling that if someone says "Jumbo jet", I think of a 747.

Just remember, it could always be worse...you could be the poor suckers who got sent down here with the two AGRS jets from up north. I'd bet they get at least 11 kajillion questions about WHAT'S THAT THEM OBUMMER DOIN TAKIN OUR AIRCRAFTS OUTTA THIS HERE FINE STATE MY COUSIN WORKS UP THAT WAY IN FAIRBANKS WHYS THEM WASH-ING-TOON LIBRULS TRYIN TO TAKE ER JERBS?????

If those guys are smart they'll just spend the entire day getting hammered somewhere way the gently caress away from their jets. They are going to be like a lightning rod for stupid, even more so than the average airshow static.

And I saw the F-22 demo rehearsing yesterday...I've seen it before but god drat, all other things about that jet aside I'm pretty sure it flies through some form of magic and deal with the devil maybe that explains why it keeps trying to kill its pilots? :laugh:, because it certainly wasn't obeying any laws of aerodynamics during that demonstration.

Yea, it really did. I was sitting in the jet leaning out of the co-pilot window being like, "I am watching a stealth fighter fall backwards and it's totally on purpose.

Hey, they may look funny but show some respect. Back in the day a pilot I know was doing a shake-down flight on an SP (no pax/cargo, super light weight) and he and the pilot looked at each other, said "gently caress it" and put the hammer down just to see what would happen. They hit about M = 0.98 with plenty of throttle left before they decided that it had gone from "gently caress yeah!" fun to "oh gently caress!" fun and that they had better back off.

A 747-SP would probably break the sound barrier if you can find a pilot with a deathwish.

It looks like some unwilling Air China pilot may have already been there.

There isn't too many interviews or indepth tracking about the AC Flight 006, but the SuperSonic Douglass DC-8 interview has a couple fascinating tid-bits.


Guy basically dove a DC-8 into a M1.01 dive where he couldn't use the control surfaces, and the plane was working without slats for takeoff because of some damage on the ramp.
