Since Flap 1 extends the LE devices I'd say that there'd be considerably more than just 'a small amount of extra lift generated'. The leading edge devices don't so much increase lift as increase the AoA margin, though of course as you "use" the higher AoA, you do get more lift. Either way...Jump to post

Don't think it's any of the above - note how the forward cockpit screen on the mystery biplane is more or less level with the leading edge of the upper wing. The front cockpit seems to be much further back on the above suggestions. The Blanik glider stored above the mystery biplane - EC-CGC seems to...Jump to post
In 1993 my girlfriend & I were flying Manchester (UK) to Paphos (Cyprus) on a Caledonian 757.

I think the OP might be referring to the significant anhedral, not the pitch angle of the stabiliser. At a guess, that would be to keep it out of the engine exhaust. Just for clarity - the tailplane is mounted high on top of the fin as a 'T' tail and has no (discernible) anhedral. Is it possible yo...Jump to post
Could possibly be more related to this kind of incident where a deployed reverser doesn't re-stow after a go-around is initiated ?

I wouldn't have thought 4 throttles would be a problem, their curved indentation shape natually fitting to 4 fingers of a hand, but I've often wondered about 6 engined (An225?) or even 8 engined (B52?) aircraft. Are their throttles easy to manipulate togther?Jump to post

Apparently there's some speculation on the Facebook threads that the An-225 destroyed in the hanger fire might have been the half assembled 2nd aircraft that was apparently stored there.
I do hope this is true and that first, airworthy example survives.

I think Brooklands airfield in the UK had an offset starter extension. In the 1960's, Vickers manufactured the VC-10 there, and since the runway was < 4000 feet, each new VC-10 was required to use the starter extension to depart to the nearby Wisley airfield (which had a longer runway) for final fit...Jump to post
extender wrote:The idea behind the Kruger Flap/Slat arrangement,was, in the event of a stall, that the inner part of the wing stall before the outboard part of the wing, thereby keeping roll control.
Very interesting thread, thanks for bringing this up. As a classic-jet enthusiast, I must say that I really miss this type of threads on A.net during the last years. It appears that there is not so much interest for early jetliners anymore. Same, it's why I chose my a.net username way back when (th...Jump to post
Cavitation is caused by a phase change, the rate of phase change depends upon local flow conditions (pressure, velocities, turbulence) as well as fluid properties (saturation pressure, densities, and surface tension). It is not a result of one factor. Cavitation is used all around us, like fuel inj...Jump to post
The slat intermediate position usually has the slot between wing and slat sealed, making the slat effectively a 'leading edge droop' in this position. This is a compromise position that develops extra lift, but at much less drag than with the slot open (e.g. slat fully extended) - which is ideal for...Jump to post
Drag is a of major importance during cruise, but when the flaps are extended (and these 'holes' appear) it's of much less a concern, indeed it's very useful for better speed control down the approach.Jump to post
How do these multiple jacks operate then if one hydraulic system goes down - with a jackscrew being irreversible? Unless they're placed in series (one after another) I guess, rather than in parallel (side by side) as you'd expect I can't see how they'd work. On the MD-11 the two nuts are connected ...Jump to post

You can't tell the angle of attack from just looking at footage or pictures. i would guess with very high resolution cameras these days sometimes you can if you (can) zoom in enough. best regards Thomas I think Starlionblue's point was that angle of attack is also a function of direction of travel ...Jump to post

The DC-8 uses a plain flap design with hinges. Airbus and Boeing usually use Fowler and slotted flap designs. I don't think they're quite plain flaps - but similar to the 707 type fowler flap where the actual rearward extention is fairly low compared to modern types which have a large area-increase...Jump to post

Shame even the big model Concordes can't get the nose & visor correct & reasonably scale.
Awesome model though !

For recent books, The Martian movie did a good job of representing what was in the book and overall hued to it. One that completely missed it for me though was Ready Player One.

Stranger still was the Lockheed Constellation, which as well as having a forward angled nose gear, had considerable 'camber' on the nose wheel axles - meaning that the wheels were angled so that the bottoms of the tires where closer together than the tops. Perhaps this was to counteract to some exte...Jump to post
Agreed - definitely the Vickers Viscount takes the prize here.
Obviously pressurisation loads were less as the ceiling was lower, allowing these wonderfully large windows.
I think he was suggesting that Airbus deployment of composites does not always ensure weight savings in a given structure. I would guarantee you the overall sun assembly will be lighter, ie the HTP. You cannot compare parts within a sub assembly as that assumes the load paths are the same. It is al...Jump to post
'Getting more performance out of the wing' has to be the least valid point I've heard when comparing the different flight control philosophies. Starting with the dubious claim that you'll be closer to max lift when at the limit of stick shaker than you would be with max aft stick. That may or may n...Jump to post
The stall begins at CLmax by definition, but I take your point about it being progressive.
For that reason, presumably in a Boeing if you fly the max energy line and there are no margins, you'd be in stick shaker?
