Landing Gear ...

Mon Jan 26, 2004 3:23 pm

hey folks,

this might be a stupid question...but i'll ask it anyway. i've always wondered why the A320 aircraft family have "TALLER" landing gear vs the B737 family?
in other words, the airbus fuselage is quite a bit higher off the ground vs the boeing. any good reasons for this ... ? thanks.

Ground clearence, the A318/319/320/321 doesnt have that unique nacell the 737 has, thus they need a taller gear for ground clearence.

Also I believe the A320 series was designed from the start as being stretch-friendly; the 737 was not. You can see the 737NG's have a taller gear than the rest.

Correct, they didn't. But bear in mind that their diameter was much smaller than the one of a CFM56 engine.

I think I remember reading when the 737-300 was introduced that the engine had only 7/8 of an inch less ground clearance than the JT-8D on the 100/200.

I've always thought the short gear on the 737 was a limiter on the design. It is possible on the -400 to strike the aft fuselage on the ground without hitting the tail skid.

I'm also pretty sure that the -900 sits higher. Whether it is redesigned gear or what I do not know, it is just a perception I got at the rollout at Renton.

All the NG's have the re-designed taller main landing gear assembly.

Thanks Alfredo. I sure thought it looked that way. I was able to walk under it which is not something I ever did on a 300/400.

Hi Slamclick. Did you get the chance to fly a delivery flight?

The taller main gear assembly is hard to notice just by watching pictures. Walking under the wing seems to be the best way to notice this. Neat that you had the chance to be at Renton  Smile
