known as the ariel truck with its unique intermeshing rotors,
no tail rotor which means all engine power goes directly to the main rotors for the highest lifting capacity...
lovely to fly and easy to land with top v/c.
find at swedbird..

What the ... is that? Double rotor, turning trough eachother? Wouldn't wanna be around when that goes wrong ...  ;D

But once again impressive work Lemoncat. You're unbeatable at the moment!

quality

Always something new....

i've seen one of those at work in Switserland... the Ka-32 has better looks

Its a strange looking thing. I saw something about it on Discovery a while back. Unusual, but highly effective

Very Interesting Concept...Nice One lemoncat

Cheers...Happy Landings...Doug

I've always thought that how they keep those rotors from colliding is something akin to magic.

bloomin ugly thing if you ask me, looks dangerous too lol.

what exactly is it used for? aerial fireworks.. ?  ;D

nice shots mate,

I wouldn't like to be underneath it when one of the gearboxes goes pop.

lol, nicely done lemoncat  ;D

Nice one, as usual. Where do you find all this stuff Lemoncat?

I've never heard of it but having little interest in helos that's hardly surprising. Kaman Aircraft started making helicopters like this when I was knee-high to a gnat. I would think the idea must be well tried & tested by now. http://www.pilotfriend.com/century-of-flight/Aviation%20history/HELICOPTERS/Kaman.htm

They always reminded me of the German Focke-Angelis Fa 223 Drache.

Kaman K-MAX originated from a specialized SAR helicopter for the USAF which was used for firefighting. The rotor wash gives the crew a chance to rescue people on the ground whitout the fire getting close.
