I'm having some difficulty trying to figure out where they're going to locate the landing gear in that exotic-looking design.

looks like a tiger moth

That "extra wide wingspan"  could cause terminal problems.

 

It's back to the drawing boards for the architects of the Sydney West Airport to redesign the ramps.

The landing gear will be in the bump under the struts. This is where most large high wings put them such as the ATR. They will need to be fuel efficient. The thin wings will reduce the capacity up there despite a bit more wingspan.

The strut makes the wing unusually rigid for a modern structure.  Nev

just nice to see the T tails make a comeback

[spenaroo]

also it struts..... or an unconventional Bi-plane, as I assume they would produce lift too

What's so good about T tails. The B 727 when first test flown had 3 times the anticipated load in the  vertical stabiliser and it transfers to the rear pressurised bulk head that had to be replaced in some DC-9 because of cracking. A T tail is also inclined to have tail strikes with early or excessive rate of rotation as there's no ground effect to speak of at that point. It will possibly require some tail (rear fuselage) bump protection . What will be the Mmo M crit of this plane?  Sub sonic cruise speeds haven't gone any where for about 50years  Where's the fuel going to be stored? There's not much volume in those wings and a very high stress concentration where the strut attaches to the Mainplanes.  Nev

rule of cool, like the Mooney
