If need be, this concept may lead to bigger piloted craft.

but the Tu-95 props r huge, their tips have supersonic speed, & it's the fastest prop driven plane in the world.e main problem with the American tiltrotor is the size of the blades which limits the speed of the blades and therefore also the top speed of the aircraft.

So, it may be that the US can't produce such powerful engines for their props?
Still, the An-70 has higher cruise speed: 466 mph https://en.wikipedia.org/wiki/Antonov_An-70In terms of thrust the D-27 generates more thrust but is unable to accelerate the An-70 to a speed faster than an Il-76 let alone the Tu-95.

the USAF needed all of them until their time was up, but if they were offered with at least 50% life left & at reduced prices, some civ. operators would've bought them.It is no accident that the C-141 was not widely sold to private companies, yet the rather similar Il-76 was very very popular and widely used.
if they & A-400Ms r offered later as a surplus & at burgain prices, some private companies may buy them. Many used DC-3s, C-130s, An-8/12s & large Vietnam War era transport helos were sold to them before. There's a Y-20 variant for civ. use:These days military forces in the west or western friendly countries operate C-17s but private companies simply cannot afford such aircraft.

Meanwhile, the ongoing struggles of the Russian aerospace industry in the face of international sanctions could even see a civilian Y-20B fill the niche currently filled by the Il-76, especially for commercial chartered airlift.
Having a civilian version available with Chinese-made engines would be a major boost for potential operators.
Tiltrotors made outside the West will be a lot cheaper to make & operate; as their price goes down, private owners will find good uses for them, even if other aircraft r cheaper to buy & operate individually.
true, esp. if there weren't new & converted freight versions of DC-10 & B-747/757/767s widely available!If anyone actually wanted them there has been plenty of time for more to be made and as they were replaced by C-17s there would be used aircraft that could be bought and used if it made commercial sense...
the wait times for Il-476s would be longer & many operators may get sanctioned for getting them, besides constant political constrains on using Russian made planes. The An-70 has better specs & could be produced under licence but the A-400M was chosen instead.They are simply too expensive to operate let alone buy... you could get four or five Il-476s for the price of an A-400M or C-17, and the operational costs would be more expensive for the western aircraft too, so the profit margin would be thin or simply not enough to take the risk.
not yet, but those re-engined Y-20Bs will help to establish it!Does China have a reputation for good reliable and fuel efficient engines?
how about a quad rotor? bigger craft will need more engines.Just my own personal opinion I would think two gas turbine engines mounted centrally on the fuselage with the rotor blades on the wing tips being spun by electric motors running from electrical current from the gas turbines might be safer... maybe with a nose mounted rotor too and a rear mounted main wing... perhaps.
