Gotta admit, when I first read this I thought Brett was trolling a helo thread. Nope, he's just a nerdInteresting. Does a coaxial configuration reduce the effects of retreating blade stall - either aerodynamically or by allowing a comparatively slower Nr?
Not sure if the AH-1Z/UH-1Y has the same.
C-17, but generally yes. H-60s all have hinges that the blades can be folded on. Not sure if the AH-1Z/UH-1Y has the same.

When specifically asked this question at a recent AHS conference, the lead test pilot deferred to the Sikorsky lawyer in the room who said they "couldn't comment on that."Looks pretty cool. Hopefully they're smart enough to consider marinizing it right away for the Navy.
I would probably agree but to play devil's advocate, consider the Army is ticked off that it is losing the Pentagon budget battle to the Navy and Air Force as it is less relevant in the "Pivot Towards Asia". Bell is claiming a 2,100 mile range for the V-280 (I have not seen numbers for the SB-1) which is way more than any helo - it also helps the Army escape the tyranny of the TPFDD. You want to spend money? This would do it.
Seems as if the S-97 might be a good replacement for either the OH-58 Kiowa or the MH-6 Little Bird. And then there is the global audience - I'm sure quite a few nations would like a 240 knot helo.

NSFW perhaps? lol...
