A343 Vs. A346 Wings - Technical/design

Fri Feb 10, 2006 7:50 am

I have a question about the wings of the A343 vs. A346. Are they the same exact wing, or is A346 stretched and/or has a root plug? Or is the A346 in fact a complete upward scaling and/or parametric stretch (for example, using the CATIA V5 parametric software) of the A343?

Thanks very much.

Hi,

Wingspans:

A343 = 60.3m
A346 = 63.45m

So I guess they do not have the exact same wing, but I don't know if it's an upward scale from the A343.

Cheers
A306, A313, A319, A320, A321, A332, A343, A345, A346 A388, AC90, B06, B722, B732, B733, B735, B738, B744, B762, B772, B7

As was discussed in the other thread, it's neither a root plug nor a wingtip stretch. It's a tapered wing insert which gives both an increase in span and in chord.

When I worked at RAF Brize Norton I was told that one of the items used to sway the RAF to the A330 tanker program was that the A330 used the same wing as the A340 so the provisions for the outboard engines could be used for the wing mounted hose and reel units. Is this not true?

Yes and no. The A332/333/342/343 wings are identical barring the outer pylons and some flap differences. So the whole idea is sound I guess.

The 345/346 wing is the old wing plus the tapered insert so there are substantial differences. Also the outboards are closer to the fuse and there are some other detail differences.
