LOL helicopter was first proven as a concept and made by russian immigrant.
Igor Iwanowitsch Sikorski, the inventor of first helicopters was well aware of Anton Flettner's variation, but didn't bother to investigate as that would require new R & D, and he was not doing all that great with his existing helicopter layout.
I just read an article about this. It was rejected by the military just because "shafts seemed too complex". What the heck? The conventional tail rotor, NOTAR or counter rotating rotors are classified as more much more complex by many books on helicopters.
I bet there were just some serious money behind in-service helicopters.
@briansmobile1 The rotors are connected to each other, sort-of, through a relatively simple transmission so the individual rotor speeds always match each other.
@lst1195
It is just plain stupid.
u.s.a. (bell and sikorski giants in particular) are insisting on inherently unstable and power wasting "one main rotor + tail rotor" design.
The system implemented in Flettner Fl 282 (predecessor of K-MAX)
was much more stable and simple and easy to use than a single rotor already back then in 1922.
us army even ditched teaching pilots on a copy of Fl 282, as it was more easy to fly and didn't prepare pilots for single rotor...

@SEThatered Yeah in the 1960's bell had some congressman by the nads. Howard Hughes was lucky to sell the OH-6A from what I've read.

Sometimes people overlook better solutions just because they mastered the worst one better.

@SEThatered Yeah the K-max looks like a born Gunslinger with a thin Silhouette & everything. Surprised nobody tries that out.

It is stable and simple.
I don't know why it wasn't utilised on military attack helicopters.

unfortunately the time required each week to untangle the rotor blades was prohibitive.

Does any one know what kind of engine they first used during initial testing?
