Hi All,

I searched for a similar posting but couldn't find anything..

Has anyone seen this picture yet? http://www.boeing.com/news/releases/2006/q2/060521a_pr.html

Are we going to see undercarriage similar to the B777??

IMO it looks more like the 767.

The B787-8 will have two dual bogies for the main gear -

The B777-200ER has two triple bogies for the main gear-

Yes, the B787 landing gear is much closer to that of the B767

That's a four-wheel truck. What looks like a third tire at first glance is actually on the other side.

One thing though... does the 787 flap its wings to get off the ground? It sure looks like it from this rendering  spin

Yeah a 767 with the gear pointed up.


The only valid opinions are those based in facts

This has been discussed before:

The 787-3 and 787-8 will have double-boggie main gears.

The 787-9 and 787-10 will more than likely have triple-boggie main gears just like the 777. Randy Basseler talked about this in one of his blogs.

I wonder if they will apply the same gear mechanism to ther 787's gear like Boeing did on the 777? I mean, if the gear will be stowed tilted like on the 767 or if the tilt is eliminated by rotating the trucks in such a way, so the two MLGs are perpendicular to the fuselage and themselves while in transit.

I would imagine they would be close to the A330s wheel config

After all it would be better at landing, unlike the 767.

For the time being, the -9 still has the double boggies of the -3/8. I could imagine the -10 recieving a modified landing gear to accomidate heavier weights and more reasonable pavement loading, but the double boggies are more than adaquet for the curret -9 specs.

The 767 is notorious for shocking landings, this is due to its landing gear config facing the wrong way. Where as with the A330 and B777 they are know for great landings.
