Morê, I see the AN22 was built in 1963 and had 6 wheel bogies, any others? Latest aircraft are the B777 and A350-1000.

AN22 have two 6 wheel bogies? Or is it six 2 wheel bogies?

I always thought that one (An22) was 3x2 not 1x6...

And the A380, which has both 4 and 6 wheeled bogies.

Makes me ask the question, will there be an 8 wheeled bogie?

IIRC Tu-144 had 8 wheel bogies back in the 60s....

Weren't they 4 wheel bogies with a double tire on each?
Think they were designed like that to be thin enough to retract edge on into the nacelles.

Maybe we should talk about axles rather than wheels?

That is 3 pairwise wheeled individually articulated gear legs per side.
compare with the C160, C17, A400M, AN124, AN225 ...

Why did the Tu-144 need twice as many wheels as Concorde, was the idea to fly from fields with much lower pavement loading like with the 154?

The B-58 also had that design, and it was because thin high-speed wings don't give you much room to hide landing gear, so you have to get creative. The SR-71 also has a bunch of small tires, because there's no room put big fat ones.

Great graphic! - but doesn't make clear if the tires are on seperate wheels or not. Anyone know?

What a great find. I had no idea that was a 2-3 cross section either.

I agree, good find and looks like a lot of hard work went into restoring that plane in difficult conditions. :thumbsup:

IMU what was asked is:
Is each tire an independent unit with individual rim and bearing or
is it a "unit piece made out of rim and spacer segments fitted with two tires each.
to check: can you independently rotate the tires on one axle stub?

I would think that they rotate independently. It would affect the aircraft's ability to taxi properly if they couldn't.

The answer is: this is one disk with 2 tyres

It's like the double wheels on a 'horse and trailer or as the Yanks call them semi's' , the rims seem to be bolted together.
