Just seen that helicopter in an news article and had to google it. Those rotors just seem unreal. Like a bug in a Video game. My head starts spinning looking at it.
Thank you for your comment! The K-MAX helicopter is truly a unique sight with its intermeshing rotors, which give it exceptional lifting capabilities and stability. This design allows for precise and efficient cargo operations, making it a valuable asset in various industries such as firefighting, logging, and construction! 🚁
The only helicopter design with a built in self destruct mechanism! Basically it has the opposite of a fail to safe! Just one small fault in one blade mechanism and you are history!!
Head Clearance? with most copters, ground personnel are only supposed to approach straight on from the side to avoid the blades.... I'm guessing the rules are different for this one where they angle down on each side? EDit: Yep, I just saw the 'approach from front' warning written on the side of it
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! 🚁
Thank you for sharing, that's so heartwarming to hear! The K-MAX Intermeshing Rotors Helicopter is indeed a unique and fascinating aircraft, known for its distinctive design and capabilities. It's amazing that your son sees it as a dragonfly - what a wonderful perspective! These helicopters are often used for heavy-lift operations, such as firefighting and aerial construction. Wishing you and your son many more special moments enjoying the world of aviation together! 🚁✨
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!
@@MattsAviationChannel yes Kaman is well known for their servo-tab controls of the rotors and it apparently makes their helicopters very pleasant to fly and excellent at autorotation in an emergency
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.
Thank you for your comment! The K-MAX helicopter with its intermeshing rotor design is indeed quite unique and provides excellent stability, especially in challenging conditions. This design allows for increased lift capacity and precision in cargo transportation. The K-MAX is known for its versatility and efficiency in aerial work such as firefighting and logging. It's always fascinating to discover innovative aircraft designs like the K-MAX! 🚁
"Warning. Approach from front." Yeah, no shit. Those rotors are seriously impressive, and they dip impressively far down on the sides. Very interesting machine.
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.
There's a K-MAX which often does tree felling operations on the hillsides near my home in Zürich. I always love to see it. I wonder if this is the same one.
That's so cool to have a K-MAX helicopter doing tree felling operations near your home in Zürich! The K-MAX is indeed a unique helicopter known for its intermeshing rotor system, which provides exceptional lift capability. It's commonly used for external load operations like logging, firefighting, and construction. Keep enjoying those awesome sightings! 🚁✨
T53 sounds so sweet during spool up. He lifted up, sat back down, started slowing the engine, and I immediately thought of Sam and Grandpa in “The Lost Boys” when Grandpa started the car, then turned it off, Sam asks “I thought we were going into town?” Grandpa said “That’s as close to town as I like to get.” 😂
Haha, that's a great comparison! The sound of the T53 engine during spool up is indeed quite unique and memorable. The K-MAX helicopter, with its intermeshing rotor system, is designed for heavy-lift operations and is often used in challenging environments such as firefighting and construction. Thank you for sharing your thoughts and for the amusing reference! 😄
i know that the rotors are physically connected but it still does look like a disaster waiting to happen and the perspective doesn't make it any better.
@@philipadams5386 If a mast (rotor shaft) or transmission housing breaks of course the gears come apart, but if that happens the aircraft is crashing to the ground anyway. They're not getting out of synch in operation.
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.
Danke Jakob! Das ist Schnee, der über die Nacht ein bisschen angefroren war. Es gab ein ziemlicher Knall, als sich dieser Schnee gelöst hatte :) Frohe Weihnachten!
@@MattsAviationChannel Vielen Dank Matt ! I wish you all the best for the new year ! Thank you for the awesome video's this past year. Can't wait to see what you have for us in the new year. Bye for now. Blessings to you and your family. Bye for now from New Jersey. 🎄🎁♥️😊👍
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
Thanks for your questions. I try to answer them as follows: The advantages of the double rotor are: No torque transmission to the airframe, thus no tail rotor is necessary and no drift is generated. And due to the usually larger total rotor area compared to a single rotor system, the same load can be lifted with less power. This makes the K-MAX a powerful helicopter. It was exclusively designed for transporting loads of up to 2'700 kg (6,000 lb). It is a real workhorse for transport missions in the Swiss Alps.
Twinblade Inspection complete!
It even sounds different when flying away. Looks like some sort of dragonfly. Still makes me very anxious lol.
Thanks for watching!
Now that you mention it, it kind of sounds like the ornithopers from the 2021 Dune

These get better lift than standard helicopters of comparable size.

I remember being dizzy and confused the first time I saw it at RJNA/NKM.
The only helicopter design with a built in self destruct mechanism! Basically it has the opposite of a fail to safe! Just one small fault in one blade mechanism and you are history!!
I'm a mechanic for one of these. Anyway, I mistimed the blades by 1 tooth and the pilot crashed and died, as a result... boy, was he pissed!
Pure poetry

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
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.
un sacré appareil
Merci!
Je suis d’accord, c’est génial !
Um…….. making that work, is INSANE
It is so nice
Thank you so much!
Wow! Never thought that design existed til now. It seems to show better stability than a coaxial configuration.

The transmission is timed so the rotors don't interfere with each other.
The setting back down and rolling off the throttles briefly was interesting… “I think I can, I think I can…”

You can clearly hear the difference to a helicopter with tail rotor.The K-MAX has a soothing sound without the typical high-pitched screeching.

@@MattsAviationChannel 🤝
Seems ultrasketchy…. What is the advantage of this configuration?
No wasted power output to a tail rotor
the startup is slower than windows 10 in commodore 64 computer.
If they go out of sync???
can't happen
Красный проблесковый маячок установлен не симметрично.
Is this the future of helicopter? Because obviously it's better in any way you can imagine.
Frankly speaking, this company is much more known for producing Ovation guitars.
what happens when one engine fails? 🤔
nothing because the rotors are connected with gears
It only has one engine
i know that the rotors are physically connected but it still does look like a disaster waiting to happen and the perspective doesn't make it any better.
Those rotors angle towards the ground way too low though, could chop off someones head dumb enough to come near it while they're spinning 😅
👍👍👍
Thank you!!
Looks a bit like a dragonfly, imo! Very cool!
My Anxiety would sky rocket just think what if one rotation is off by a mili second.
The rotors are geared together, so there is physically no way for them to get out of synchronization.
@@brianb-p6586 Yes, but there are more parts than just gears, and it is those that can cause a failure in synchronization.
@@philipadams5386 If a mast (rotor shaft) or transmission housing breaks of course the gears come apart, but if that happens the aircraft is crashing to the ground anyway. They're not getting out of synch in operation.
Oh it is Twinblade
this is something a james bond villain would try and get away in
Fascinante
Если он такой компактный и грузоподъёмный, то почему он не используется во флоте, на десантных и авианесущих кораблях?
I wouldn’t even go near this helicopter 😅
Fantastic
Thank you!

Some brilliant engineer looked at a regular old helicopter and said: “How can I make this even more dangerous?” And by the Omnissiah, they succeeded.
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.
Wow, I want to be Enginer!!!!
Sweet video.

Идея интересная и звук классный. Но вот если проскользнёт хоть одна шестерня - винты убъют друг-друга и вертушка полетит камнем вниз.
Wood pekeer has entered the chat
Makes me think of the Ornithopters in Dune
Can’t see how that could go wrong. 😅
what if the gear slips, what a dissaster it would be

Great take off Matt.''
Thank you Trevor! It is a workhorse in the Swiss Alps.
I swear those rotors are what anxiety looks like for aircraft people. It's really cool and I have no doubt it works super well, but •~•
You couldn't pay me to get on
They're probably interlocked... Couldnt hit each other any more than you could get both pedals on a bike to point down at the same time.
@@GodBlessCanada Yeah, that's it. I did once see a video showing off how intermeshing rotors work
@Caldo De Olla you need Jesus not meds
@@busybody1474 My experience differs. Now let's get back to helicopters. What's your opinion of the K-MAX?
Nice ! How does this thing pirouette though ( at 03:17 ) without a tail rotor ? 🤔
The most shocking to see *No blade collision.*
not really shocking when you realize that the rotors are mechanically connected
Ein Hammer gutes Video Mathias.

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
are we ever going to see an intermeshing 3 blade? time marches on
What could possibly go wrong
What is the science behind it?
Me,
as a teenager twirling 2 broomsticks between my hands, until I hit myself in the mouth with 1 of them
No tail rotor so what are the feet controlling ?
Cool! I wouldn't want to be within a mile of that abomination!
Bonkers. Great document of this extraordinary design. Thanks.
This design is a tragedy waiting to happen!
why? the rotors are mechanically offset
One little glitch and it’s all over.
Is that system less efficient than a Chinook? On this thing, the trust is split into vectors pulling on the airframe in opposing directions.
Tolle Aufnahmen!! Schöne Feiertage und Grüße aus Innsbruck 😁👍🏻
