For some reason, the Flettner rotor system is aerodynamically stable in hover, unlike all other helicopters; and it takes input from the pilot to do anything else. The contra-rotating and intermeshing rotors balance the rotational forces, so no power is wasted on a tail rotor. The K-Max uses servo-tabs for control of the blade pitch, so no hydraulic system is required.

Wow, it's fascinating to learn about the Flettner rotor system and how it differs from traditional helicopter designs! It's great to see that this system is more aerodynamically stable in hover and doesn't require the energy-consuming tail rotor. And the fact that the K-Max uses servo-tabs for control of blade pitch is a clever solution that eliminates the need for a hydraulic system. Innovation in technology never fails to impress me!

Its because daul rotors tend to cancelled out the drift from the other which is why single rotors have a secondary rotor in the back to cancel it out

@Neckername1

So basically if you lose power, as long as you can keep the rotors moving, you'll have a higher chance of surviving by not getting caught in a downward spiral due to lack of power to the rear rotor.

I only heard of intermeshing rotors a few moments ago and I was blown away on how they made something like that work. Obviously it clearly works but I couldn't believe my eyes at first. Very cool

Basically, from what I understand, only one rotor is powered. The other moves because of the gear or gears connecting it to the powered rotor. I'm pretty positive that's how the gearbox is set up. If I'm wrong, then I accept that and will endeavor to better understand the inner workings of the aircraft.

Truly a Awesome lifting machine

The K Max is so intriguing. It’s so ugly it’s weirdly beautiful, made so by its tremendous utility. It can lift well more than it’s own weight. The sound of the rotors at speed is a general fluffing and whooshing like a thousand big birds, and no tail rotor buzz of course. So different from sound of the two-bladed Bells and multi-bladed Sikorskys and Hughes we’re all so used to and can pick out for miles. I have heard there are issues with training however. The K Max is only single seat and the only two-seat intermeshing rotor helo is the Kaman Huskie, of which the couple of remaining airworthy examples are beyond their useful lifespan.

I used to live just across the Fraser river from a heliport that had one of these. Less noise than a logging truck. Silent compared to a Bell204

Thank you for your observation! Indeed, the K-MAX helicopter has a unique feature with its intermeshing rotors that allows for a different approach procedure compared to traditional helicopters. The design of the K-MAX rotor system reduces the need for a tail rotor, which in turn allows for a safer approach from the front. The warning to approach from the front is a crucial safety measure specific to this helicopter model. Your attention to detail is much appreciated! 🚁

How does it yaw? I’ve been trying to think of how it might do that, but my pea brain betrays me. 😬

How does this vehicle yaw? It cant play the game where the 2 rotors are spinning at different speeds.... so ?

It's like I know the blades are 90° apart and can't connect without something seriously going wrong. But also that thing looks like it's ready to just explode.

Frankly speaking, this company is much more known for producing Ovation guitars.

No tail rotor so what are the feet controlling ?
