In the days before turboshaft engines, coaxial and intermeshing rotor (Kaman) machines were an effective way to make maximal use of the limited power available from piston engines. When the powerful and light turboshaft engines arrived, the inefficient "penny farthing" designs, with tailrotor, became dominant. The advent of electrically powered helicopters, with their limited power capacity, could see a return to the more efficient designs.
@@manofsan No, not at all. If you are referring to the reduced downward thrust vector due to the slight angle of the blades, this is more than offset by the energy required to constantly flap the entire rotor blade of a non-Kaman design. The Kaman "Flaperons" are very lightweight and require no direct rotation of the rotor blade, opting instead to flex the blade through the aerodynamic force of the flaperon. Each mast has its own "swashplate" located underneath the mast rather than at the top like most do, and since the controls are manipulating only a slight force to move those lightweight flaperons the entire mechanism is significantly lighter weight than conventional controls. Another benefit to not losing all that energy through constantly rotating the rotor blades this way and that is that the entire rotor system on a Kamen lasts about as long as the airframe itself, rather than requiring regular replacement. The Kaman intermeshing rotor system is extremely energy efficient, helicopter-wise. The intermeshing rotor system was invented by a Nazi named Anton Flettner, who also designed the Rotor Ship (sailing ships with huge columnar rotors rather than fabric sails).
@@manofsan Yes, I would vote for the K-MAX, which has all the advantages of the Flettner plus the many innovations Kaman invented. It is an incredibly versatile machine, and can be fitted as a UAV that can switch back and forth to Piloted Mode with the flip of a switch. Which Kaman is your favorite, and why?
true, i was referring to the home-built nature of manned flight at the forefront of technology,a nd developmental integration of it. I see you have one too!
Yea I'm sure they forgot that part and being that you're the smartest person on the planet you caught it for them before they crashed and died so good job Sangyoooon you saved a life !!!
Well, where is the flight? Do you know why they did not show it? Because the first separation from the ground for another six months to work. A fly - so it's generally very far, given what kind of pontoon, but not very competent country is engaged in the project :)
wow this is excellent. One thing i noticed..the prop is kind of low, i think you should just place higher landing gear under the helicopter to lift it higher. and you should make a conventional version of this that is gas/petrol powered then i guess it would sell like crazy. especially if you have a kit version. and if it was a 2 seater , would be even better,
Can I buy a copy of this product or just a kit form from you? What is the power rating of your e-copter and how much will it coast? Thanks. How do I contact you?
You do know that most of the noise you hear from a flying helicopter is the main rotor and tail rotor chopping up the air right ? You only really hear the engine distinctively when taking off and close to ground hovering
I had not expected This from Yuneec.. Good to see they didn't go the multirotor route (as in quad or octa).. I am a bit disappointed they Are going the stick-control way with this though :(
+roidroid, Likely to settle yaw during forward flight for smoother flight rather than rely only on coaxial torque adjustments to counter undesired yaw. You don't want to the stabilization control system do all the work to have constantly bump minor adjustments to keep the thing straight.
You want this one? this is an electric helicopter. This is innovative, but no electric helicopters today can offer any meaningful flight duration and range. At least not yet. Do you have a helicopter license? If you just need a good performing & reliable kit helicopter, that I can help you. If you like, you can send me your email address and contact info to info@aviasia.net
I hear SYMA and EACHINE are collaborating on a new 4 passenger quadcopter. It will be powered by ten thousand 3.7 volt rechargeable batteries. (Batteries not included)
I have an atmosphere powered jet engine and atmosphere powered vehicle engine now. This electronic engine is just one engine I have many more want to learn about them? ; )
well of course it fly, these days an average person can make a multicopter that carry themselves... these Yuneec guys are experts they know what thye are doing, still under testing stage but later on you will see it in action
Ну и где полёт? Знаете, почему не показали? Потому что до отрыва от земли ещё полгода нужно поработать. А летать - так это вообще очень далеко, учитывая, какая понтовая, но не очень грамотная страна занимается проектом:)
As a former sikorsky mechanic I am impressed. I would love to build my own small micro copter ;) Just need cheap land to do it.
Can we work together to built this tiny heli....
Seek out the brothers Nolan, they have valuable knowledge you may find of interest in your quest, godspeed my friend. Now go!

I thought that Kaman machines were less efficient, due to their off-vertical slant. I've heard their rotorheads are simpler, though.

@@adamchurvis1 - which is the best Kaman-type intermeshing machine, in your opinion? Is it Kmax? Which is the most modern/advanced of these machines?

@@adamchurvis1 - I don't know enough to have a favorite - but the Kmax does look impressive in its lifting capability.
Now this is just Too Cool!!!!, I have a Yuneec Q500 plus drone and it is very great quality and a stable platform,,,,I know this will be great as well
Nice to see aviation in China going in a positive direction. In the US, the FAA has made sure that it cannot. At least someone is doing it.
Sikorsky had an electric helicopter flying in 2010.
true, i was referring to the home-built nature of manned flight at the forefront of technology,a nd developmental integration of it.
I see you have one too!
Does it fly?
a bit too small for me but thumbs up for starting new design of helicopter and not just converting helicopter to electricity.
hum.. does it have rotor pitch change mechanism..? Looks like it doesnt...
Yea I'm sure they forgot that part and being that you're the smartest person on the planet you caught it for them before they crashed and died so good job Sangyoooon you saved a life !!!

That model already exists........... x10
OTPHxerx OTPHxerx ... Which prop?

I thought the point of an electric motor is its quietness...first theres music covering the engine noise then the sound is muted.
You do know that most of the noise you hear from a flying helicopter is the main rotor and tail rotor chopping up the air right ? You only really hear the engine distinctively when taking off and close to ground hovering
2016....so tell me what's going on now it's 2018?? Love to have one.
Its a good job but how long it can fly.
Rashmi Ranjan Nayak just remembered, the Wright brothers didn't fly that far. First attempt
what its the energy storage Bank and power of the motor.
Sure, nice design. have some other ideas for you if you are interested.
I had not expected This from Yuneec.. Good to see they didn't go the multirotor route (as in quad or octa)..
I am a bit disappointed they Are going the stick-control way with this though :(
DutchRC Adventures Best to start out with low complexity and high reliability
Sure.. it's not like 'we' are starting out with heli's now though..
DutchRC Adventures They are. 😁
Boring :P I want to see it auto fly after punching in de destinations location :) Yuneec has quite a bit of experience in that field
Why does it have a tail?
roidroid because it's helicopter,lol

good video, good music.
what is the power of electric motor?
A unicorns tear
@@weirdscience8341 you cracked me up so hard ! priceless reply
what is an ELECTRIC motor powered by???? AN ELECTRIC ???? ELECTRIC MOTOR??????/ maybe the ELECTRIC MOTOR is powered by WATER !
@@helinick81 how much watt and volt

I foresee a slight problem for anyone taller than 5'
It's small and beautiful(:
I am interested to this work

if God wanted birds have a rotor,instead flapping wings,He would did it !
Surely this is a troll
I can come over and fly for you guys...
good job
China new stealth helicopter that will do 385 MPH and can carry two Gatling guns on each side .
Maximum range 10 metres, max flight time 30 seconds?
The Nolan Brothers would be spinning in their graves.. (if they were dead)
linda maquina parabens
Weill, it spun, but it didn't fly....
Not finish yet, you need a swash plate and links to control pitch and collective.
I like there products. Q5004K , Typhoon H.
I have a new electronic engine design that could power this helicopter that would give it unlimited range. Interested?
Jim Martin Will it power my 5ft tall dildo?
You interested in buying one for your clone queen? It misses her candlestick maker so much you should buy one for your clone queen. ; )
People are so very nasty these days it must be due to some nasty parasite infection that thinks its a god? ; )
I have an atmosphere powered jet engine and atmosphere powered vehicle engine now. This electronic engine is just one engine I have many more want to learn about them? ; )
Jim Martin ... You need to keep those secret. Don't tell any one.
BUT DOES IT FLY. WTF. DO A VIDEO WHEN IT FLIES .
well of course it fly, these days an average person can make a multicopter that carry themselves... these Yuneec guys are experts they know what thye are doing, still under testing stage but later on you will see it in action
Fixed pitch blades so no autorotation...

After Mr Yu Tian left Yuneec, his ex-wife held the Yuneec now, and I don't think Yuneec can make out any impressive product now.

One BIG drawback...made in China.
Just like all Apple stuff you probably love...
China has good stuff for the right price as well as bad stuff for the right price too...
