The British, "Westland". At the same time.
At the same time, the next generation of helicopters in the late USSR was planned to be something like this. V-100, "Kamov".
However, the USSR collapsed, military budgets were reduced. As a result, even the Americans began to consider a program to replace the currently flying helicopters (Future Vertical Lift (FVL)) only in 2004. And only one "normal" helicopter was offered as part of the program. The others:
The Pyasetsky X-49 SpeedHawk is the earliest "prototype prototype".
The company dropped out of the program quite early, but did not change the principles. In 2016, Piasetsky's opinion about the "light" helicopter of the future looked like this.
In addition, the company offered options for upgrading current-generation "Apache" helicopters according to the same scheme
" Chinook "
Well,and the Apache modernization project from Boeing (Advanced AH-64E Block 2 Compound), for the company.
Another early loser, EADS, was going to offer something based on this.
The one of loser in the middle distance AVX Aircraft
Karem Aircraft turned out to be less prone to self-promotion and its helicopter version is somewhere too far away in the depths of the Internet.
And the finalists Boeing-Sikorsky under the reconnaissance and attack helicopter program: S-97 RAIDER
He is also the software in the final stealth version.
The alternative was the "classic" Bell 360 Invictus.
As a result, the program was closed in favor of drones. At the same time, it was opened when it turned out that the abandonment of the "Comanche" in favor of the same drones was premature and reconnaissance from a manned helicopter was about 40% more successful.

Аnd here in the background you can see that Boeing-Sikorsky has planned to replace the "Apache".
– and this is a video clip.
But then "Bell" came with its tiltrotor and ruined everything. In general, the pusher propeller scheme will face tough competition with tiltrotor aircraft. However, those have a reduced payload due to the limited diameter of the rotors. This is not critical for "average" transporters, but heavy niches are questionable.
At the same time, it cannot be said that Boeing did not try to spoil everything for "Bell".
Something in the dimension of an "Osprey" with telescopic folding blades and a central part of the rotor that works like a round wing.

And something much easier.
Russia, the SBV program, has been publicly available since 2017 The "Mil" Design Bureau previously showed a helicopter project with a pusher propeller. Mi-X1, it's pretty boring. "Kamov" Design Bureau in 2018
700 km/h, but the method remains quite mysterious. Previously, "Kamov" promoted the idea of a jet helicopter, and even earlier, it developed a "quasi-jet". In general, this is a rather peculiar branch of development, it takes quite a long time to describe it.
