Revising the A380 NEO MLG
« on: December 01, 2017, 11:26:03 AM »
In this very informative thread; viewtopic.php?f=5&t=771991&p=11193763&hilit=a380+wing+high+efficiency#p11137069
Ferpe and Klaus pointed out that the A380 MLG design takes up a lot of potential cargo volume, also because the 6-wheel bogie can't be stored upright.

In recent discussions we've looked at a light weight non stretched A380NEO. In this post: viewtopic.php?f=3&t=1377885&start=800#p19976285 Tomcat roughly calculated that a 16 wheel MLG (instead of 20 wheel) would probably be able to handle about 505T. That seems like a huge weight reduction however, assuming a 14% SFC reduction from a GTF engine over the trent 900 and a range reduction to about 7.700NM, there could easily be a 50T weight reduction from the 1st order fuel load decrease alone.

This would mean that there would be no more 6 wheel bogie and perhaps there would be scope to store it upright after all. This might free up some cargo volume making the plane more competitive for other airliners.

What do you guys think, would:

1 Would it be technically possible to rearrange a 16 wheel MLG so it is stored more efficiently, freeing up cargo volume?

2 Apart from being technically possible, how big a change would this be? Is this something so far reaching that you could effectively start from scratch?
