OK, since you decide to proceed, you are really, really there. One point for the correct name of the device and the way it is tested by this vehicle.

Sorry, I did not realise Allemano was waiting for Otto.

Please disregard my answer, and I'll stay out of it for now...

This one is free for all.
Otto was really close, Allemano probably got it, you are pratically there.
One point is still there for the correct use of this vehicle.
Feel free to proceed at your discrection.

a headwind generator, placed at the end of the runway  ???

When it will be solved, 2 or 3 of you will say...that's it? was it so easy?
Read the past replies and you'll find that it's almost solved....

Testing the wing brake flaps?

Not that...someone was really close, pratically there....and from now on, only complete answers: how this vehicle is supposed to test the still unnamed braking device.

A kind of drivable "shoe" which slows down the plane while its landing gear is locked in the openings/intakes of this 'device'?

Probably pure nonsense.....  ^-^

Yes...pure. (much easier)

Well if I was close with the arrestor cable testing.

The machine would be fitted with an arrestor hook and placed at one end of a runway with the cable stretched across at the other (or about halfway down).

You would power it up and bring it up to about 120mph (normal landing speed for most aircraft) and send it down the runway.

As it catches the cable it will be bought to a stop (we hope) presumably by varying the engine power it can simulate different weights of aircraft.

Any good?

The device is called arresting gear, and it is correct, but the dynamic you wrote is not...(too expensive in case of cable failure, don't you think?)

well in that case the only other way I can see it working would be to attach it to the cable and try to pull it from its mountings on the runway. You could do this facing the 'wrong way' to give you a mile to bring it to a stop in case of a snap!

That's very clever indeed, but it doesn't work like that...

Ah - I hadn't thought of that. There's also the hook-and-wire thingy on carrier decks. Allemano, please jump in if you have it. Like that Crosley puzzle, I'm running out of ideas.

I don't have any idea either. Already made my guess which was a complete failure ;D

The remaining part is really not so hard...take a look at my 2nd pic and look how it was supposed to work in the drawing...then it's just a simple matter....

For testing braking parachutes?

gilescooperuk was right, it is a testing vehicle for the arresting gear...now the point is to find out how it is supposed to do that...it is not going to hit the cable with a hook, and a clue can be found in the drawing I posted...

Does the hook grab something on the guide rail?

Now will be a matter of time:
the pic above the drawing shows the system...it's there!

There's an arrestor hook on top of the cart.

I guess that the cart is pushed up to speed by the jet engined vehicle. After this vehicle stops pushing and brakes or makes the turn, the cart runs into to an arrestor cable.
