787 Crosswind testing in Iceland

[anonymous-user]

787 x wind testing in Keflavik.

There are some clips from the A380 testing on there also.

impressive stuff... I do like the 787... nice looking plane.

Wonder how they get the wires/pipes/driveshafts to stretch when the wings bend?

Beautiful crosswind landings - look absolutely textbook to me as a layman

Driveshafts from the fuselage to the wings? interesting idea :P

Duhhhh, how else would it move when its on the ground

I like the flexed up wings. nice plane.

It doesnt move, the runway does. But will it take off?

From the film "The jewel in the Nile" You can see the drive shafts quite clearly

Just a bit quieter than a 727.

Not as daft as you may think. The BAe146 has a hydraulic motor in the fuselage, that drives the flaps, via a set of drive shafts in the trailing edge.

whats hanging off the tail of the plane, is this some sort of indicator for wind speed Vs plane speed

I flew in/out of Keflavik once - thankfully it wasn't like this!

Just the question I was going to ask.

[El Guapo]

Is it normal procedure to use a customer's aircraft for flight testing? I would have expected this plane to be sporting Boeing livery.

Can't see the video at work, but I assume it is a "static cone", used during development and test work to provide a reference static pressure reading from a position remote from the airframe.

If everything's segmented enough it wouldn't be any different from any other large aircraft. Likewise the control surfaces are segmented, hard mounted at one end of the hinge line, and floating at the other. The surfaces themselves will either bend with the wing, or are designed to have their mounts move, without having any interference with the surrounding structure.

ZA002 (the one painted in ANA colours) is not going to be a customer aircraft, nor are the other 5 test aircraft. ANA is the launch customer for the 787 though, so it is free advertising for them, and a sign of trust in Boeing that nothing untoward will happen in testing (not good if a plane in your colour scheme goes down!).

Interesting. Thanks for that.
