To my opinion not. The model just shows, what a helicopter using a cross flow fan driven rotor
could look like. And for this purpose, the inventor used the model of an OH-6 Cayuse, you can
see the "non needed parts" in the photo above of those you posted.

are you sure about the Model 211 - shouldn't that be the Model 200 and Model 202?

can you quote your source?

Nagler used the basic OH-6 Cayuse airframe for several of their projects, including the Model 205 (not built) and the Model 255 Shehana (test-flown, see photo). However, their rotor arrangement was conventional and nowhere near as odd as this idea.

Post #276 Section "User Artwork" Motocar's Cutaway drawings
Cutaway Voltjet 585, a more modern proposal of the concepts presented by the British in the early fifties of the rotor driven by small burners on the tip of the blades as the design submitted by the firm Farey Ultralight Helicopter firms, this new project belonging to US firm Voltjet International Corp. Voltjet also used a turboshaft light to move a small compressor and fuel burners tips of the blades, the advantages is that the torque of the rotor is removed, but did not use a small rotor control yaw but a flap controlling the exhaust of the engine at Pratt & Whitney PT-6 c-30, this in theory favored use on oil rigs in the North Sea where were diriguidos their marketing efforts and where helicopters convecionales have difficulty landing in stormy or rough water conditions, the project has not advanced beyond the proposal and published an article in Popular Mechanics magazine february 1987 and April 1987 in its edition in spanish, the illustrator was the artist Jeff Mangiat and retouched by Motocar to clean and unite the two images, was taken from the web mimecanicapopular.com

Hi folks.

Just to complete this thread, I am uploading the picture of the NH-120, which I have found in the American Helicopter Society newsletter form the February of 1955. The aircraft registration is N74054. Visible is the flat 4 boxer engine installed between the rotors.

Seems that up tho this time google images does not have this one ;)

Enjoy!
