Two Crossing Rotors | Syncropter

- This is K-MAX, an anxiety machine, also known as a synchropter, or, intermeshing-rotor helicopter, which is a synchronized twin-rotor, turning in opposite directions.
This technology was developed by German Anton Flettner in the 1930s.
But what's the magic that prevents the blades from colliding?

Note 1: This video is an adaptation of a video from my Brazilian Portuguese channel called "Integrando Conhecimento".
Note 2: "The appearance of U.S. Department of Defense (DoD) visual information does not imply or constitute DoD endorsement."
Synchropter and coaxial copters are my favorite. The manual blade servos was a great idea. No hydraulics required.
Or tail rotor.
i love this helicopters appearance. it's so odd, and so different, but somehow, so beautiful.
This video is better than most K-max videos
😮 PHENOMENAL EMERGENCY LANDING @1:10 ! Straight Bossed it!
The KMAX blades are not wood. Those were on the earlier HH43. They can contact and wipe across each other if there is too high of a pitch command. That results in mast bumping ,damage and usually replacement. When I quit working on them it costs about 275K per set.
Interesting video. No anxiety here, I knew of the Kaman helicopters beforehand, but I didn't know about the inventor's interest in music too. Some people have so much "headspace", it makes me a bit jealous (but still appreciative of their contributions to tech).
Ovation guitars were Kaman owned in the beginning.
I work down the road from Kaman in Connecticut and get to see them do low level test flights over my building and around the area. One of my coworkers worked there too. Cool design maybe I'll work there one day.
I have just discovered your channel and I cannot overstate how much I enjoy your videos. I subscribed after watching only 1. If I was to offer some feedback I would love you to go into more detail on some of the things you mention, for example the control method of the blade pitch around 2:37. You cover so many interesting things so quickly I find myself skipping back and pausing so I can take it all in. Thanks for making these video and keep up the excellent work. I've followed aviaition for nearly 45 years and I learned so much I never knew in these last 8 mins (well 12 actually with all the rewinding 🙂)
I'm really happy that you liked it.
Intresting video! These Kaman helicopters are weird, but so unique!
Great video mate. This was the most interesting video I watched all week. Thanks.
German engineering is greatest in the world!
Really like your Videos, keep on uploading!
Thanks man
I know it’s probably true, but it seems odd that a tail rotor adds even close to the weight and complexity that a second main (and synchronized) rotor does!
I notice a lot of stick shake in those cockpit videos, is this common in synchro-mesh helicopters?
Great video, thanks !
The answer to the question asked in the title, is answered in the titel as well. It's why they are called SYNCHRO-pter.
So, Theoretically, we could have 2 sets of these intermeshing rotors where 1 rotor blade intermeshes with 3 other rotor blades ? Arranged in a rectangular or square pattern ? Would such an arrangement reduce turbulence ? Much like the Chinook ..
The Kellett K 10 had blades collide many times, A light in the cockpit lit each time the blades touched... It flickered one too many times canceling the project... The pilots Nopped their way out of town.
I think the rotor blades are made out of wood… and they are nearly $2,000,000. Great job on your video!
New blades are fiberglass the old wood blades were better, Wood tends to dampen vibrations
they use the same modell next to our home inside of Zürich city to transport the logs from the steep hills.
Love this channel and its content
Underrated
When are they going to invent something that can withstand winds & x-ray through clouds? RIP KOBE, Gianna & Friends 💛💜
Awesome vid ! 🌞
If there was a rear rotor in case one of the engines fail it could still function untill landing
Great content .... Now I want an omlette !!!?
Excellent!
KMAX ❤. It reminds me memories of my Helicopter project lecture back in 2012.
Nice Video
Great video! 0:33 there is a misspelling of Paperclip (Papaerclip)
The question asked in the title is literally answered in the title. Let me ask you this, How does Earth's gravitational force keep the moon from drifting out to space?
Why does this guy say “German scientists”? It’s kinda weird how he’s avoiding saying Nazis..
Your right!
UA-cam demonintizes (doesn’t pay creators) if videos mention the word nazi
I didn't think so... he mentioned operation paperclip right away, which we all know about so obviously we know some of the scientists were nazi's. The video is about the technical aspects of a 2 blade rotor 👍
With Absolutely no disrespect in any way. But to me a helicopter is, 3000 moving pieces, flying formation, all looking for a way out!
Did he makes the Husky, the helicopter the Marines used?
All this time I thought it was luck.

Searched for this and accidentally put another o instead of the p and got an entirely different result.
