"... Airbus engineers added two short wings extending from each side of the fuselage. The wings meet at a point and support a rear-facing prop driven by the engines turning the main rotor. In forward flight, the wings provide additional lift, and those small props provide additional propulsion. All of this allows the helo to achieve higher speeds without pushing the main rotor into an aerodynamic red zone"

About time they did something about all the vibration on the first version with the thrust propellers mounted on a single cantilever strut.

problem is nasa went on a patent blitz of anything they could patent regarding not seen or implemented ideas such as a single wing wrap around, those fan mount wings begin to resemble a patented entity. It's not easy being first in anything, ohh the stories in my own life, just when I thought there was a ray of hope BAM along comes VTX. The nasa patent thing took place around 2014, of a single wrap around wing, one I discovered after making up a concept Chinook with one and stumbling across the patent in google searches for other aviation things of interest. Even nasa isn't original in that either.

Regarding the vtx reference, some time was spent reading about vtx's in the hf Mikado forum, a design borrowed in part from Sikorsky "X2" helicopter. The hf guru busts vtx a little right here https://www.helifreak.com/showthrea...t=784751&page=2

and after a little more reading and consideration (reading more vtx in the Mikado forum) I begin to see the marketing front ep of hf gets on about.

Breaking new ground in aviation costs BILLIONS at the fs level like the Airbus H160, the r+d and red tape alone.

btw, years ago, 2013, a hobby store had a mall copter with box art that when viewed from a different perspective, squinting. showed a heli with wings like the Mil24 and something like small turbine fans near the ends to make a compound heli, looked awesome and I have been slowly taking design cues from it and adding to my personalized helis (good for me) lol. Unlike Eurocopter x3 the wings were low, turbines allowing low wing placement on longer wings with less vibes than props. That allowed a smaller main rotor diameter. I think I kept an image of it in my photo files.

Look closer at NASA and their habits and you'll see that they patent anything and everything they think of . . . and then try to market it.

Another pet peeve of mine is the attitude of organizations like ASTM. Have you ever tried to get a copy of some of their specs that all industry uses ? They are very protective of those but willingly take an $arm and a $leg for a copy.

I know, having catalogues of airfoils attributed to them but not invented by them, when referenced always comes to naca this or that number airfoil like naca is the last word on the topic.
