K-MAX Intermeshing Rotors Helicopter Startup & Takeoff

That’s amazing. Never seen this one before. Very cool

Twinblade Inspection complete!

Me,
as a teenager twirling 2 broomsticks between my hands, until I hit myself in the mouth with 1 of them

Looks like a Gi Joe Combra Mamba helicopter..

You know that thing you used to do as a kid where you would just swing your arms like a combine-harvester...? That wasn't meant to be inspiration!

Удивлен, что оно построено и эксплуатируется! Эта схема совершенно нерациональная, создающая массу проблем. При данной схеме каждая лопасть постоянно из зоны пониженного давления врезается в зону повышенного давления т.к. они меняются местами - нижняя становится верхней. Если лопасть сверху, то вторая разрежает под ней воздух, а если снизу, то вторая сжимает над ней воздух. На каждом обороте происходит удар каждой лопасти и вообще огромное множество нестабильных завихрений. Уверен, что это приводит к значительно более высоким нагрузкам на лопасти - вибрации, скручиванию и нестабильному полету. Даже по звуку слышны эти ненужные удары. Все равно, что штаны через голову надевать при помощью специальных молний и застёжек, то есть, можно конечно, но зачем? Чем их не устраивала соосная схема?

are we ever going to see an intermeshing 3 blade? time marches on

What could possibly go wrong

Those blades make my brain hurt

I understand the engineering but still don’t trust it. I know some of you secretly agree with me.

Groovy ride man..

Takes a while for the brain to settle down after watching that for the first time.

It's a river if it's wrong

You know, I understand the how. What gets me is the why. Real passenger and cargo capacity is out of the question. To me it's one of those just because you can doesn't mean you should situations. Fun to watch, but I'd hate to count on it every day to function perfectly. I know all aircraft are dependent on flawless engineering. This design is like just asking for disaster.

LOBILLOS MUSICAL DE DURANGO.

c'est quoi l’intérêt?

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 😅

I would NOT trust that weird rotor design... 😳

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.

Синхрокоптер.

Если он такой компактный и грузоподъёмный, то почему он не используется во флоте, на десантных и авианесущих кораблях?

Hahaha, imagine the two rotors colliding with each other during mid flight.
What a pathetic design 😂

Is that system less efficient than a Chinook? On this thing, the trust is split into vectors pulling on the airframe in opposing directions.

Pinochet was based

They should have put this helicopter in gta5 over all the bland helicopters they added that nobody buys.

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.

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.

The setting back down and rolling off the throttles briefly was interesting… “I think I can, I think I can…”

I remember being dizzy and confused the first time I saw it at RJNA/NKM.

There’s one of the most loudest jet on the chopper

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

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.” 😂

It even sounds different when flying away. Looks like some sort of dragonfly. Still makes me very anxious lol.

If this was in a video game It would be too easy to take it out. One random bullet at the blades and they would crash into each other crashing the whole thing

Even with the slow startup, I still can't imagine how the blades work with each other. Very cool design.

Ispe bharosa kaise karain

My special needs son really likes that helicopter 🚁 says its very unique in design and we both agree that it looks like a dragonfly!

Wow! Never thought that design existed til now. It seems to show better stability than a coaxial configuration.

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.

I like the russian heli better. Something about the rotors on the US job bothers me.

Har, har, har " Approach from front, " Besser wäre "Bleib weit genug weg"

Looks a bit like a dragonfly, imo! Very cool!

Is this the future of helicopter? Because obviously it's better in any way you can imagine.

Wow, I want to be Enginer!!!!

No tail rotor so what are the feet controlling ?

little chinook sounds :)

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.

Bitchin' Machine!!!!!!!

These get better lift than standard helicopters of comparable size.
