Could A330 Use 6 Wheel Instead Of 4?

Thu Jan 19, 2006 6:21 am

Hello all

We all know B777 have 6 wheel boggy instead of the standard 4 wheel boggy. I was wondering could Airbus adopt the 6 wheel boggy for A330-300?

comments are appreciation please.

I'm Sure They Could But There Is A Size Difference Between The A330 And The B777 So I Don't Think It's Necessary To 6 Instead Of 4.

I figure there would be size differ. Although they both almost the same size.
Would it look cool if A330-300 had 6 wheel boggy? I thought it would be..

According to A.nets database, the max. T/O weight of any A330 version is 513.000 lbs while the heaviest B777-version is rated with 752.000 lbs.

It would also be a tight squeeze for a 6 wheel bogie to fit into the landing gear bay. And having the slightly better load distribution across 6 instead of 4 wheels probably won't have that large an effect (if any at all due to the smaller size of tires?).

And the landing gear engineers have got enough work to do on the A340 Enhanced gear, A350 gear and improving various A330/A340 gears without having to deal with a complete new layout!

unfortunately aircraft are not designed "to look cool"

why use 6 wheel bogies when 4 is adequate?

As mentioned above, the weight of the A330 does not require a third axle. This question did make me wonder something else, however: what will Airbus do with a HGW A350 variant should one be developed? After all, the -900 is being aimed at the 772ER. My guess would be the use of the A340 center bogie--though would that interfere with the new wingbox?

Look & actual weight are two different reasons.Performance matters not the outside look  Smile

why put 6 wheels on a an aircraft that only needs 4, it means extra maintenance cost (tyres, brakes and so on)

If airliners were designed to "look cool" to a.netters, then the 777 would be a T-tail three holer with winglets. Efficiency is more important than looks. Its only secondary that some efficient designs look great.

In reponse to Dw747400 (reply 46):

The Airbus 350 won’t be using a centre bogie, as used on the330/340.Using a centre bogie means that there is less space to stow the main (wing mounted) gear, so it is necessary to design the main gear legs to shorten as they are retracted. Having no centre bogie bay means the shortening mechanism can be eliminated, improving reliability and maintenance requirements, and it also means there is more space available to fit larger wheels and tyres to the main gear if needed.

MLG is Messier Dowty. NLG hasn't been decided yet but is in process of being done.

I know there is no center body gear on the current A350 proposals, but was wondering if in the future Airbus would consider a HGW version of the A350 to extend range and payload (this seems possible as the new engines mature to higher power ratings). These modifications could push it closer to mid-range 777s in terms of takeoff weight.

The 900R is going to have 6 wheel bogie like the 1000.

Sure. But why would you want to? If you wanted to significantly up the MTOW of the A333, it would be far easier to adapt the centre leg from the A340.

Not that much adaptation needed. The A330 has the centre gear housing fitted already, it's left empty.
I am sure it would be easy to fit one if necessary.

In 2000, remember Airbus was looking at a long range version of the A333, and it was to have a center wheel bongie.

Why wouldn't they just be designed from the outset to swing into the wells without shortening, wherever the wells are inboard or outboard ? Shortening legs aren't a requirement to hit wells on the extremity of the fuselage.

Do you spend a lot of time looking for four year old threads to comment on? Obviously a LOT has changed with the 350 since 2006!.

I hadn't heard about this before. Why didn't they build this beast: Lack of a suitable engine, or did they feel they couldn't compete with the 77E?

But why did US put a 6 wheel boggy on their 757? They had the 4 wheel boggy on them before and a 757 wouldn´t really need 6 or am I wrong?

As far as I know - no 757 has ever had a six wheel bogey, only ever four.

It does not have 6, its just an illusion. Its just the angle of the shot showing up the front 2 wheels of the right MLG. But i admit it does look like it has 6.
