15 minutes gives you just enough time to get high enough to do a autorotation.. Which I wouldn't want to try in a electric helicopter. :/ I could see this being usefull if you were putting a camera on it to take pictures because of less vibration.. But then why not just get a electric rc helicopter? Cheeper and you can still get your good pics.

Direct taildrive is much bether. You can have the best tail rpm. Nothing will changes the pitch so you wouldn't notish a thing.
Just google for fun under direct taildrive.
With less rotating parts it would even use less power, although there is an additional motor and motor controller it still will use Less power and longer flight time's ;)
@Dragon69Fly Direct drive has worse response time compared to transmission drive. It takes milliseconds to send a signal, where a mechanical pitch control is instantaneous. Delayed control is bad, so direct tail drive is bad. It also won't save that much power.
Honey! I'm going to the corner store to get some eggs, milk, cereal, chips, and toilet paper, in less than ten minutes. Love you honey, and be back soon!

It won't be very quiet unless they kit it with some more advanced blades, like those whisper blades they're putting on some of the new military craft.
Though just reducing vibration from the engine will go a long way to extending the life of the air frame.

Well someday, when you have batteries that weigh half as much, and provide six times the power, and need a quarter of the recharge time, you'd have youself a nice quiet lil' whirlybird.
100 years ago, the Wright Flier wasn't very impressive, by today's standards, either.
But, like the Wright Bros., you gotta start somewhere, and Sikorsky has. Good job!
They need to take a walk over to Tesla Motors, 5 years ago, they build a car that will beat a Ferrari, flat out in the quarter mile, hands down, it will smoke a Ferrari. That was like 5 years ago, on battery power alone... They've had RC Helicopters 4 years ago, that will lift 5 or 6 times their own weight, and the best that Sikorsky can come up with in 2010 (with 70+ years of building military grade Helicopters) is a knock off, of a 1960's crop duster Helo, that can get 15 mins of blade time..?
Put the electric motor at the hub of the rotor blades and you could simplify the mast machinery for tilting the rotor, especially for double rotor designs.
I think it's outstanding. But hears the problem. 15 mins and I bet some serious money went in to them batteries. Why can't you have a small generator that continuously tops up the bats. I no it might seem contradicting to have a combustion engine but it could be a little air cooled diesel converted to bio fuel. I think that that would work. But I'm no scientist or engineer so my plan would more than likely be flawed. But just an idea is all.
what the hell is the point of this prototype and/ or project? there's absolutely no innovation here. what we would like to see is battery technology. what a waste of goddamned money. rich, stupid, bastards.
@thekaizer666 So R&D is a waste of money, then? No matter what tech you have around you right now there has been a ton of prototypes before the actual product. Prototyping is how new stuff gets developed.. They don't just wake up one day and go "so lets just build and produce a new mp3 player today. We'll get it right on the first go as always." If you knew the amount of effort that goes into R&D you'd understand why certain things are hella pricy.
@ronnysoeberg before the prototyping phase there needs to be a *proof of concept*. in this case, there ISNT; battery technology is the current bottleneck in such applications as these. I didnt diss R&D, and this is NOT R&D. Besides, it looks like this was a favour from some rich dad (shareholder) to his son (the nerd in the video) to produce such a "prototype". He can't even handle a simple interview!
@ronnysoeberg "Leave it to some mega corporate educated fools to design an electric helicopter that looks like every other helicopter ever made AND fly's for 15 minutes. This gets back to what I've been saying for years, that the corporate educational establishment is training you college grads to memorize, NOT to think with any great depth, but to just do pretty much what all the corporate educated goons before you did.

@ronnysoeberg "...gyrocopters are by FAR more efficient than helicopters, so why don't they just tilt the main rotor back ... that a clutch can be used to disengage the main rotor to fly it strictly as a gyrocopter, or engage the main rotor for hovering, vertical take off and solid control in high winds. Come to think of it, this heli design is pure crap. The VERTICOPTER is the future. Gravity plane + verticopter is best.
danielvincentkelley 1 month ago" >>> THIS should have been more in vein
@thekaizer666 Verticopter seems completely useless. The whole body of the plane needs to be super flat for the whole rotating propeller assembly to be of any use.. So it's basically a 1-2 seater leisure craft.. No load carrying ability to speak of. That's pretty much what choppers are for. Vertical take off and landing, hovering, transport of wounded/soldiers/cargo to places with no landing strip etc. Verticopter can do none of that. It's like a flying car.
@ronnysoeberg hi, i cannot and did not claim that i am qualified as of yet to comment on alternative configs such as above, but the point that i was trying to put forward was that this particular project should have at least been at such a tangent e.g. the hybrids or electric cars were very focused on their aerodynamic (yet ugly) shapes, regenerative braking, engine coasting etc.. This project demonstrates nothing but "how a conventional helicopter looks like if we added batteries to it".
@ronnysoeberg to shoot closer to home, the latest super fast helicopters by sikorsky where the tail was facing backwards (x2? x3? im really lazy right now), now theres a prototype, with proof of concept, instead of just slapping rockets to the side of a conventional helicopter, or replacing the power train with a nuclear one, hoping that it would be a revolutionary thing.
hmmm i have time to take off and land at the same spot. and then recharge for 8 hours , lol I think its great someone made one at a huge cost to test the technology its just not there yet. it would have been better in an ultra lite glide or gyro plane.
These are the clowns that are taking all the jobs, because they have an uncle or a dad or a brother or someone that worked at such & such company. They got the job based solely on WHO they know, NOT what they know or their amount of competence. Meanwhile, people with Master's Degrees, and a ton of experience, that aren't fortunate enough to be as well connected, couldn't pay someone for an interview.
It's the living proof of our technological capacity to change TOMORROW (if we want) to green energy in every single aspect in our life :) GO ZEITGEIST
They need to combine this with a Perendev permanent magnet generator, thus the electric helicopter would have infinite flight time. Another solution would be to carry compressed hydrogen gas and a small internal combustion engine to spin a generator to feed the heli electric juice. I wonder also if they connected a transmission to efficiently use the torque the e-motor is spinning.
Plus, EVERYBODY knows gyrocopters are by FAR more efficient than helicopters, so why don't they just tilt the main rotor back a bit and put a second rotor driving forward connected to the same motor, that a clutch can be used to disengage the main rotor to fly it strictly as a gyrocopter, or engage the main rotor for hovering, vertical take off and solid control in high winds. Come to think of it, this heli design is pure crap. The VERTICOPTER is the future. Gravity plane + verticopter is best.

Well by replacing the tail rotor with an electric one, would have some problems if the tail rotor motor were to fail. If you sudently lost all power and had to enter autorotation, you would want to have tail rotor authority, driven by the main rotor. So that idea don't sound so good to me. Good concept. The only thing to keep it straight would be the verticle tail stabilizer and would only be good at speed.
Must weigh a ton with those 2 battery packs... he says "It's at nearly gross weight before the pilot steps in"... does it actually fly then with all that weight... thats the problem with battery powered vehicles they're so heavy that most of the batterys power is sapped lugging all that weight around... and thats why they will never take the place of conventional fossil fueled vehicles until they can reduce the ridiculous weight disadvantage... yet?!
ok putting an electric tail motor on a heli = BAD. coming from an rc background you CANNNOTTT autorotate them!!!!! that means instant crash just about anytime there is a failure!
Also if anyone has ever flown an RC heli thats battery powered. You know that power out is a sudden thing and there is not auto rotation. Of course I don't want to compare the two too much.
Hmm 1100 pounds of batteries. I don't like that at all. Especially for a 15 minute flight. Where am I going to go in 15 minutes? I will take a 400 pound engine and 700 pounds of fuel for a 2 hour flight.
@DobermansRock technology will change all that,that is the point of these conversion,if we can do it and make it work now,think of what they will be able to do in 10 years.Electric is the future,there's no stopping it now.combustion engine have another 40 years years before they start to fade away.thats my good guess.
@inagod I cannot see electric ever replacing turboshaft or jet engines. Fuel fed engines in the long run are lighter and run longer. The problem for electric is the batteries(their weight) and the short time they last. The only way electric works is in the applications we have today in the Navy. Nuclear Subs and Aircraft Carriers. I do like the performance of the electric motor. The Carrier is so fast it is classfied. It is able to do what it can because of it's on board nuclear reactor.
when they take out the gearboxes,main and tail box, get rid off all that weight and mount electric motor directly on each rotor this might actually work :) then it just has to come remote control and you have a full size RC
I have no real comment until I see it fly... but, one for Jonathan, the guy on camera giving the presentation: "Stare at the camera instead of the cue cards".
Calm down people! This is a technology demonstrator. It's just a start, and as technology improves, so will flight times. There are already electric powered airplanes that can stay in the air for 2 hours or even more.
15 min not to long ...why not use a alternator as the rotor spin's to recharge the batteries in flight and that will give 5 -8 hrs flying with no refueling
its not that complicated ...we just cant seem to get away from fuel
All you bone heads talk about 15 minutes of flight time. This was the first one built dummies. Besides even though the technology is new this helicopter would reduce my trip to work from 45 minutes to about 15. And I wouldn't pass a single car.
Also electric motors are far less likely to break down in mid flight. Give this technology three more years and then you might get it.
Try looking for an alternate source of fuel!!! Its hard to believe, With Todays Technology All you can achieve is 15min of fly time.. That is usless and a gross waste of money. I Do not see a demo avaliable either. Come on... Battery Power to Assist in cars an scooters has shown to be more costly than useful. Wishful thinking.. but battery power for flight is a bad choice.
As we can now see with RC Model Heli's real power and resonable flight times are available.
The unit here is an internal combustion craft that has been modified, that is never ideal, especially for a helicopter where weight is so critical, I estimate that this craft could fly 45min+ now if it was weight reduced. Best of all build it from scratch.
again i ask, if your going to show something off, at least demo it. sure your speech is good, but the star of the show is the craft, so start it up, ok?
Electric cars are not green , were does the power come from that charges the batteries most likely a power station burning coal. Same apply's whit Electric Helicopters.
@Pyware50 Hell of a lot easier to control emissions from a smaller number of point sources then it a distributed source like say all the cars in america. Not to mention that the energy could one day be provide by renewable's or nuclear energy which is much less emissions intensive. The main problem is energy storage; batteries are the curse of us all.
@jetplaneflyer, okay smarty pants explain the theory behind the high bypass fan system. Correct me if I'm wrong, but this system uses the speed of the engine to create the mass of its thrust, does it not?
Okay now put that motor into the combustion section of a turbine engine; removing the combustion section, as I been talking about for too many years; ever since 1991 when I was in junior high. Some motors have higher RPM range than some gas turbines.
Why would you do that?. An electric motor already generates mechanical torque so why not use it directly rather than take huge losses in efficiency and much added weight that would be implicit with all the fans, turbines and gearboxes of a turbo system?
@jetplaneflyer, sorry I wasn't very clear on my comment. Think outside of the box for a minute. What is the max RPM or a typical turbine engine? What would be the thrust if converting a jet fighter engine to full electric. Most of the engines have a forward mounted generator so supplying the needed power for the battery pack should enable non-stop flight, power loss and efficiency shouldn't be an issue.
You cant replace a combustion section with an electric drive.. Combustion expands the inlet gas (air) to tens or hundreds of times it's original volume due to chemical reaction processes involved in combustion, it's this expansion that creates thrust. There is nothing you can do with an electric drive that would do that. even if you spun a jet turbine at full speed it would make hardly any thrust without combustion to expand the gas.
Just awesome - being a energy pioneer is always expensive and it seems rarely generates direct profits, but is an environmentally responsible way to do business and shows clear industry leadership - keep it up guys - thanks!
Know if they can figure out , how to use the electro static energy generated from the blades to recharge the capbatts, and trim some of the weight from the drive train this might be a fun project.
You're wright, but the key issue for helicopter is an engine. I think that R&D from Sikorsky Company should focus on overunity electric engines - that's probably the best solution for power retention. Good Luck !
Also interesting is the use of Lithium Ion cells. One of my first early RC helicopter Kit designs back in 1999 made use of the FIRST Tadiran Lithium Ion cells for RC helicopter use, then of course came Lithium Polymer , rechargeables and now high discharge Li-Pols, which in my opinion, is currently the way to go. A new technology in even lighter, safer and even higher discharge cells will some day, in the perhaps near future, obsolete the gas engines used in commercial aircraft.
@MarioIArguello You won't see fuel propulsion jet engines ever being replaced by electrical engines, this includes commercial aircraft such as jetliners. However you may be right about replacing the combustion piston engine found in most ground vehicles, boats and small air vehicles (e.g. helicopters).
Unfortunately though, the propulsion from a jet engine is partially directly due to the combustion and force of burning/expanding gases through the engine. H2O2 will replace jet engines
Most of my original MIA Micro-FLIGHT helicopter designs and upgrades for RC helicopters still promote the motorized tail rotor direct drive, for the simplicitry and efficiency it provides WHEN DONE PROPERLY. This has made perfect sense to me since my first RC helicopter electric design back n the late 80s. It is very interesting to see electric propulsion being adopted in real helicopters. Check out my Channel and web site MIA Micro-FLIGHT Blog and Museum for some more interesting stuff.
@DomenicoScarlatti Understable first impression. It's a concept helicopter. The fact that it even gets off the ground, let alone can stay there for 15min is rather impressive. Helicopters, unlike fixed-wing aircraft, are rather hungry in terms of power-to-weight requirements. If the reverse were true, we'd all buy airline tickets on big helicopters vs. jets and turbo-props ;)
Most Impressive. Even with 15min endurance, that's really pushing the power-to-weight ratio of electric aviation. Yuneec, with their impressive E-430, is going to have to make room in their spotlight for Sikorski, Sonex, and others. (Sorry, my designs only fly in PC simulators ;) )
Pretty cool. I didn't think they've come quite this far yet. Curious to know if anyone has tried doing an electric plane and how much of a duration it would have flying wise. I could kind of see something like this in a smaller scale for sailplanes.
@Jimfoxyboy Google "Yuneec". Sonex is also doing a bit of work. And Eric Lindbergh (grandson of THE Lindbergh) is also invovled in promoting electric aviation. No lead-belching overweight BP-end-product-guzzlers here ;)
@green95gt LOL, sure does. Aviation and other engineering fields are full of very talented, often hella cool people who aren't necessarily on-camera personalities ;)
Lol, its like an oversized rc heli! But really I like how confident Sikorsky is with their new project and I think it is a great step in finding alternative power suppies for our aircraft.
@bagelboi66 Nahhh... he's not THAT big a boy. Smaller people obviously will enjoy better performance in any vehicle - be it motorcycle, car, fixed-or-rotary-wing aircraft, or steamship. (STEAMSHIP??? Yes.... just to a much smaller extent) ;)
Well done Sikorsky Innovations! I look forward to the mature products. Thanks for helping move us along. Lets kick our petroleum addiction one product or testbed at a time!
The weak spot of electric aircraft is not the motors so much as the battery system. Batteries have low energy density in comparison to hydrocarbon powered internal combustion engine; until that weakness is solved, battery powered manned aircraft will remain an experimental technology with a few niche uses. A more feasable approach (for now) may be to use an internal combustion engine to generate electricity for the onboard motors. Just a thought...
@All2Meme Agree, a hydrogen burning engine say, would be a better approach. They did not mention how long it takes to charge up that half ton battery.
@fireengineer Do you think a hydrogen burning turbine engine would work best in this situation, turning a large alternator to power the motors in the rotor drive system? I think it would make sense, as most successful electric drive vehicles have an onboard engine to generate their power (diesel-electric locomotives, for example). It might make for an interesting aircraft.
Very limited, so much technology needs to mature for this to be viable. Full points to Sikorsky for the concept model but in my opinion it will be a decade before we have the super high efficiency motors and chemical batteries to make this happen on a commercial level.
15 minutes gives you just enough time to get high enough to do a autorotation.. Which I wouldn't want to try in a electric helicopter. :/ I could see this being usefull if you were putting a camera on it to take pictures because of less vibration.. But then why not just get a electric rc helicopter? Cheeper and you can still get your good pics.

@thekaizer666 Verticopter seems completely useless. The whole body of the plane needs to be super flat for the whole rotating propeller assembly to be of any use.. So it's basically a 1-2 seater leisure craft.. No load carrying ability to speak of. That's pretty much what choppers are for. Vertical take off and landing, hovering, transport of wounded/soldiers/cargo to places with no landing strip etc. Verticopter can do none of that. It's like a flying car.

@ronnysoeberg hi, i cannot and did not claim that i am qualified as of yet to comment on alternative configs such as above, but the point that i was trying to put forward was that this particular project should have at least been at such a tangent e.g. the hybrids or electric cars were very focused on their aerodynamic (yet ugly) shapes, regenerative braking, engine coasting etc.. This project demonstrates nothing but "how a conventional helicopter looks like if we added batteries to it".
thekaizer666 1 month ago
@ronnysoeberg to shoot closer to home, the latest super fast helicopters by sikorsky where the tail was facing backwards (x2? x3? im really lazy right now), now theres a prototype, with proof of concept, instead of just slapping rockets to the side of a conventional helicopter, or replacing the power train with a nuclear one, hoping that it would be a revolutionary thing.

They need to combine this with a Perendev permanent magnet generator, thus the electric helicopter would have infinite flight time. Another solution would be to carry compressed hydrogen gas and a small internal combustion engine to spin a generator to feed the heli electric juice. I wonder also if they connected a transmission to efficiently use the torque the e-motor is spinning.
danielvincentkelley 2 months ago
Plus, EVERYBODY knows gyrocopters are by FAR more efficient than helicopters, so why don't they just tilt the main rotor back a bit and put a second rotor driving forward connected to the same motor, that a clutch can be used to disengage the main rotor to fly it strictly as a gyrocopter, or engage the main rotor for hovering, vertical take off and solid control in high winds. Come to think of it, this heli design is pure crap. The VERTICOPTER is the future. Gravity plane + verticopter is best.

Well by replacing the tail rotor with an electric one, would have some problems if the tail rotor motor were to fail. If you sudently lost all power and had to enter autorotation, you would want to have tail rotor authority, driven by the main rotor. So that idea don't sound so good to me. Good concept. The only thing to keep it straight would be the verticle tail stabilizer and would only be good at speed.

@inagod I cannot see electric ever replacing turboshaft or jet engines. Fuel fed engines in the long run are lighter and run longer. The problem for electric is the batteries(their weight) and the short time they last. The only way electric works is in the applications we have today in the Navy. Nuclear Subs and Aircraft Carriers. I do like the performance of the electric motor. The Carrier is so fast it is classfied. It is able to do what it can because of it's on board nuclear reactor.

Also electric motors are far less likely to break down in mid flight. Give this technology three more years and then you might get it.

As we can now see with RC Model Heli's real power and resonable flight times are available.

Okay now put that motor into the combustion section of a turbine engine; removing the combustion section, as I been talking about for too many years; ever since 1991 when I was in junior high. Some motors have higher RPM range than some gas turbines.
Scorpion85629 7 months ago
@Scorpion85629,
Why would you do that?. An electric motor already generates mechanical torque so why not use it directly rather than take huge losses in efficiency and much added weight that would be implicit with all the fans, turbines and gearboxes of a turbo system?
jetplaneflyer 7 months ago
@jetplaneflyer, sorry I wasn't very clear on my comment. Think outside of the box for a minute. What is the max RPM or a typical turbine engine? What would be the thrust if converting a jet fighter engine to full electric. Most of the engines have a forward mounted generator so supplying the needed power for the battery pack should enable non-stop flight, power loss and efficiency shouldn't be an issue.
Scorpion85629 6 months ago
@Scorpion85629
You cant replace a combustion section with an electric drive.. Combustion expands the inlet gas (air) to tens or hundreds of times it's original volume due to chemical reaction processes involved in combustion, it's this expansion that creates thrust. There is nothing you can do with an electric drive that would do that. even if you spun a jet turbine at full speed it would make hardly any thrust without combustion to expand the gas.

Also interesting is the use of Lithium Ion cells. One of my first early RC helicopter Kit designs back in 1999 made use of the FIRST Tadiran Lithium Ion cells for RC helicopter use, then of course came Lithium Polymer , rechargeables and now high discharge Li-Pols, which in my opinion, is currently the way to go. A new technology in even lighter, safer and even higher discharge cells will some day, in the perhaps near future, obsolete the gas engines used in commercial aircraft.
MarioIArguello 1 year ago 4
@MarioIArguello You won't see fuel propulsion jet engines ever being replaced by electrical engines, this includes commercial aircraft such as jetliners. However you may be right about replacing the combustion piston engine found in most ground vehicles, boats and small air vehicles (e.g. helicopters).
Unfortunately though, the propulsion from a jet engine is partially directly due to the combustion and force of burning/expanding gases through the engine. H2O2 will replace jet engines

Most of my original MIA Micro-FLIGHT helicopter designs and upgrades for RC helicopters still promote the motorized tail rotor direct drive, for the simplicitry and efficiency it provides WHEN DONE PROPERLY. This has made perfect sense to me since my first RC helicopter electric design back n the late 80s. It is very interesting to see electric propulsion being adopted in real helicopters. Check out my Channel and web site MIA Micro-FLIGHT Blog and Museum for some more interesting stuff.

@DomenicoScarlatti Understable first impression. It's a concept helicopter. The fact that it even gets off the ground, let alone can stay there for 15min is rather impressive. Helicopters, unlike fixed-wing aircraft, are rather hungry in terms of power-to-weight requirements. If the reverse were true, we'd all buy airline tickets on big helicopters vs. jets and turbo-props ;)
negativewashout 1 year ago
Most Impressive. Even with 15min endurance, that's really pushing the power-to-weight ratio of electric aviation. Yuneec, with their impressive E-430, is going to have to make room in their spotlight for Sikorski, Sonex, and others. (Sorry, my designs only fly in PC simulators ;) )

The weak spot of electric aircraft is not the motors so much as the battery system. Batteries have low energy density in comparison to hydrocarbon powered internal combustion engine; until that weakness is solved, battery powered manned aircraft will remain an experimental technology with a few niche uses. A more feasable approach (for now) may be to use an internal combustion engine to generate electricity for the onboard motors. Just a thought...

@fireengineer Do you think a hydrogen burning turbine engine would work best in this situation, turning a large alternator to power the motors in the rotor drive system? I think it would make sense, as most successful electric drive vehicles have an onboard engine to generate their power (diesel-electric locomotives, for example). It might make for an interesting aircraft.
