DARPA/Boeing DiscRotor

[VikingRaider]

That is some complicated, stupid-fuckin'-shit that'll never see production!! F**K

[Mahkaite]

Next: Only the disc, and then we have an alien space ship! >:D

[willian32976]

i hate when they pull shit like this!! they should state that the vid is a cartoon!! it's too hard to tell that it is a cartoon by the thumbnail pic! plus that thing is really lame looking!

[SonOfAgony]

Wow a helicopter with wings.

[dreamerein]

The V-22 isn't cost effective. We need a replacement. If this design is relatively simple it would satisfy a need.

[symmetry08]

inefficient design, too heavy

[Theadamman1]

why do you need a rotorblade IF YOU HAVE WINGS AND JET ENGINES.

[OppirompaMiDotCom]

@Theadamman1 VTOL?

[7777chugun]

actually, a piece of shit.there is nothing useless device

[Sagramorbald]

DARPA, Derp's vehicle of choice!

[kotnnl]

Good copy of russian project

[NameNotAlreadyTaken2]

Truly bizarre. I highly doubt such a craft could survive the forces it subjects itself to and stay reliable enough to be militarily useful. This thing looks like a maintenance nightmare, assuming it stayed intact long enough to make it back for maintenance.

[Tome4kkkk]

For an engineer it's funny how it's easy to tell many of those concept animations have been done by amateurs (not aero engineers). In this example: swept wing used for subsonic aircraft, tunneled propellers used for aircraft, most probably too nose-heavy. All of which done, because it looks cooler :)

[CrosswindApproach]

@Tome4kkkk "tunneled propellers" lol mr. "engineer"

[Tome4kkkk]

@CrosswindApproach ""tunneled propellers" lol mr. "engineer""

I used a direct translation from correct Polish term, so excuse me mr linguist.

[CrosswindApproach]

@Tome4kkkk Excuse me then. But as an aero engineer you should know that carefully designed ducted fans actually raise the efficiency. However, wetted area (skin friciton) and weight is increased.

[CrosswindApproach]

@CrosswindApproach I don't agree with your sweep statement either.

[Tome4kkkk]

@CrosswindApproach "(...)you should know that carefully designed ducted fans actually raise the efficiency."

Thank you Mr. obvious but that would still be a bad idea for the particular project...

.

"However, wetted area (skin friciton) and weight is increased."

...for these reasons, to be precise.

[CrosswindApproach]

@Tome4kkkk Maybe they want it to go as fast as possible without the use of jet engines and averall efficiency is priced lower. Hard to say without knowing more details.

[lupabuatchannel]

Steady I Really Like This Video The aircraft takes off vertically like a helicopter, with telescoping rotor blades extended, then converts to fixed-wing forward flight by retrating the blades into the disc, which is then stopped.

[cenedywong]

Good, I like that you share this video, I wish success always Boeing is studying the feasibility of the DiscRotor high-speed verticla-take-off and landing aircraft for DARPA

[melisantika]

Nice Video That You Share , So Very Nice Thanks You The aircraft takes off vertically like a helicopter, with telescoping rotor blades extended, then converts to fixed-wing forward flight by retrating the blades into the disc, which is then stopped.

[pemburuiklan]

I Really Like The Video From Your Boeing is studying the feasibility of the DiscRotor high-speed verticla-take-off and landing aircraft for DARPA.

[anakmudajaman]

Your Video Is Very Useful Sharing Boeing is studying the feasibility of the DiscRotor high-speed verticla-take-off and landing aircraft for DARPA. The aircraft takes off vertically like a helicopter, with telescoping rotor blades extended,

[1950Viper]

This has absolutely nothing to do with DARPA in any way.

[qHighFlyerp]

gyrocopter...

[alexcala1]

jesus another person good with a computer program but can you actually make on, again not impressed

[edbapemo]

Distribution limited? Damn. I need a hundred!

[Falewick]

Looks too big to be able to land where helicopters are supposed to. But it would certainly be faster than the Osprey.

[KaAten71]

@TheDragonBF2 also the main rotor (the rotor on top of the DARPA) can tilt slightly backwards to cancel the forward momentum of the wing rotors

[KaAten71]

@TheDragonBF2 perhaps the force required to keep the DARPA DiscRotor from rotating is less than the force required to overcome forward inertia so the craft can stay stable in a hover using just only the wing rotors/jets

[KaAten71]

to chakuman2: the wing rotors or jet engines compensate for rotor rotation. if the aircraft wants rotate oposite the disc rotor the engines on the wings compensate

[TheDragonBF2]

@KaAten71 the jets will have no counter-rotational support during hover - think about it ;)

[chakuman2]

no tail rotor? how do they compensate rotor rotation?

[NewVahan2011]

Flies on computer only LOL

[DerSturmerSS]

how and where it hides complex rotary wings?

[whiteskullwhiteskull]

Cooool !!

[keithktam]

oh, fuck youtube for asking you to type those words in every two comments!!!!!

[keithktam]

but does it has to be a disc?? as long as the blades can retracted right??

[UltimatePwnageNL]

>_> that wont work in this setting. the top rotor puts stress on the wings...

[zbjnrn71511]

Doesn't the Osprey serve the same purpose? To take off like a helicopter, but fly as fast as a plane?

[VideoRoom207]

@zbjnrn71511 took a long time to get the kinks out of it too, i could see this being a money waster trying to get it right, although a cool concept, no?

[BMuris]

Is it just me or does this thing really look very very inefficient?

[natchangdesu]

できそうでできないシリーズですね。ホバリング中はどうやって反­転する力を抑えるんでしょうか。ゲームの中だけですね。

[theinsane101]

I played this game 

[killytbe6]

more silly things humanity doesn't need

[ps3specter]

That'll be a hell of a thing for it to be stable without a tail.

[cnoyes72]

@ps3specter , I was thinking the same thing. Without a tail rotor (or a set of counter-rotating blades) the torque generated would make this thing unstable (to say nothing of being safe).

[iwanthalo3]

@cnoyes72

i would think that the ducted fans act as the "tail rotor"

[dumbledizzle]

The tilt rotor system looks more efficient

.

[tegarac]

Fucking americunts think onley for wars!!!!

[freezingsun8]

@tegarac lol hater

[keithktam]

although is as ugly as ever, is also very cool!! should put it in Command & Conquer!!

[CatPilot]

OK, I'll bite. How does this thing...counter rotor torque to keep it from spinning out of control in a hover?

[aymric]

@CatPilot It _could_ use the fans on the wings to accomplish that, but I doubt it.

[m1leswilliams]

@CatPilot Just thinking the same thing...

[WarBambi]

i think this already exist...i believed it called the V-22 Osprey currently in service

[telemetry9]

i've always wondered why they're not using electric turbofans with in built dynamos. Quiet and super efficient flight. solar panels built into the frame to augment the battery. This is possible now - so please build it. (not as a murderous drone though!!!).

America - you need to check your Kharma levels. (shudders).

[soundslave]

@telemetry9 Dynamos in an engine wish is powered by those dynamos? Doesn't that break the law of thermo dynamics?

[HarryVoyager]

@soundslave I think he is thinking electric motors. (At least I hope he is.)

While in theory and electric fanjet is possible, a 1000hp electric motor will weigh 2-3 tons, while a 1000hp turbine weighs around 100-200kg.

Then there is the battery energy density problem. Lithium-Ion batteries have an energy density of 250-340 W/kg. Gasoline? 13,000 W/kg.

[biginchsmallblock]

@telemetry9 because everything in your comment is NOT efficient in an aircraft, or physically possible. Also, there is no such thing as Kharma.

[telemetry9]

there's no such thing as kharma/karma?

strange - i've seen it in action quite a few times. must have been my imagination.

[finka123456]

@telemetry9 Probably since there is no evidence for it and the fact that cannibal kigs have gotten away with their crimes in this century. Also werid that the leaders of sudan are living fat while commiting genocide...moron

[ChrisXn777]

Was that guy on the side the pilot escaping or just dropping off a few refugees back home?

[Spirality0]

how come they never show it dropping chemical weapons?

[titykaka1]

or you could invent the harrier like a baws

[bulgogi1212]

Unfortunately, the Boeing DARPA was replaced by the Pakistani DIRPA DIRPA

[TheNattak]

Duuurp!

[ACTORDAVIDTRAN]

Schwarzenegger had one of these in that movie, "The 6th Day." :)

[Giggidygiggidy12]

@ACTORDAVIDTRAN Yeah and it looked way better than this monstrosity

[ACTORDAVIDTRAN]

@Giggidygiggidy12 Psh. Giggity, YOU GOT THAT RIGHT!!!

[bestamerica]

'

wow that is a new to me,,,

2 jets are too big and heavy weight,,,

try to make 2 small jets and light weight

[Elthenar]

In what way would this design be better than the Osprey that's already in service?

[Bloodmane1987]

Bullshit.

[hxly2]

Why do the blades have to be retractible? How about just disconnecting power to the rotor in level flight and letting it rotate freely like a gyrocopter? This will reduce complexity and weight, and the rotor can continue to provide lift.

[CaptBubble]

@hxly2 Check out the Fairey Rotodyne (on You Tube)

[bilbo117]

@hxly2 It will provide drag not lift in that state

[MrVlada011]

Ideal for picking up NATO murderers after assassinations, and-or drug smuggling CIA operations.

[captainjeff86]

@MrVlada011 what a moron, lol. he must be mad that NATO jets bombed his village or something

[MrVlada011]

@captainjeff86 ahahaha thats so funny! people loosing their homes and lives! I hope you laugh all the way to the shelter some day too..  ;)

[MrSchpankme]

This technology is 20+ years old.

[GeneralArrow]

@MrSchpankme Why do you think we know about it lol

[CognitiveNetwork]

@MrSchpankme Get over it. NASA is still using technology from the 60's for their space programs, calculating coordinations and for the launching system.

[PyR0Star]

i just want the RC version cuz it would be fucn awesome

[littleneddygoestowar]

It has the same problems the Osprey has- there is not suffcient need. Our current helis perform better than this would as a heli, same goes for our jets/planes. Combining the two only would prove useful if you didn't lose a ton of performance.

[SEThatered]

Hmm as far as i know helicopters do not like big flat surfaces under it's main rotor.

And here you have 2 wings...

and before you start shunning the non-believer, watch this:

/watch?v=cWa7g3wtRkg&feature=r­elated

[KiloByte69]

AND I WANT ONE OF THOSE SO FUCKING BAD...

[serpentphoenix]

this is awesome! So wait is present day materials and engineering sufficient to build one of these?

[welshfluteplayer]

This is a good idea

[9gent]

that thing is ugly

[Terryzarzoff]

I thought of asymetrics, but the lag in the thrust uptake vs. instant torque would still produce significant yaw.

[wacher8]

UFO>>>>LOL

[glavonjagrob]

DARMA SHIT

[Tjita1]

Anti-torque, anyone?

[lossif88]

UNE BONNE IDEE BONNE INVENTION

[MrMKH2010]

This is old news. The Faiery Rotodyne did that in the 1950's

[jeshelm11]

I hate when people leave a comment that only says: Dear Santa...

soooo fucking unoriginal....

im looking at you MrBuzzyfuzzy

[Innovoid]

fake... why does it have such a big diameter center for the pals... :/ it doesnt make sense

[KRAJISNIK21]

easy target :)

[god604]

you know they were using this type of aircraft during the raid on Osama bin Laden's compound? now you know.

[Cult1022]

@god604 what the heck are you talking about? that's utter bullshit!

[god604]

@Cult1022 lol no i swear, the aircraft that crashed at the site of Osama bin Laden's compound in Pakistan was a prototype aircraft similar to this. It was supposed to quickly pick up the SEAL 6 team after the assault on the compound and make a quick exit but it crashed. There was footage of this aircraft taken in the morning after the assault. The version of this aircraft that crashed at the site was a lot smaller.

[SirScarecr0w]

@god604 no it wasn't, the one that crashed in the compound due to vortex ring (the helis own rotorwash caused it to decent) was a UH-60 black hawk heavily modified to reduce noise and radar cross section.

[MrBuzzyfuzzy]

Dear Santa...

[Starfish99100]

[Pindo34]

Great.. Star wars is here...

[NifoOtiBoy]

Sikorsky X-2 design is way simpler and weight efficient I would think.

[SharkStrikeAC]

interesting concept. Anyone know if there is already some prototype?

[charums]

@SharkStrikeAC

it is a stolen concept. first russian scientist have developed this idea. i am not sure about that the founders of american company knows why this type of flying vehicle has been envisioned by russians. They even dont imagine the mission of this vehicle. They have just stolen it and artisticaly captured a video on computer :) looser americans...

[martinkoolen]

Interessant.

[dreamburn1]

The engines on each wing counteract the torque from the motor with a differential in thrust, or some clever ducting..

[DEFENDERCRUSADER700]

OH! THANK YOU I DIDNT KNOW I WAS GOING TO FLY IT!

IT LOOKS NOTHING LKE A CRASH HAWK!

[DEFENDERCRUSADER700]

OH! THANK YOU I DIDNT KNOW I WAS GOING TO FLY IT!

[charums]

it is a stolen russian project, like all others :) I can send you the resource, if anyone is interested.

[Puls4rt]

cool



[autahi49]

@atomikus37 ha ha good one

[pjmack79]

@engaurd wow, so when did that happen? you know, i saw the footage of the chopper crashed in Pakistan during the raid, and it looks exactly like this.

[pjmack79]

how is this better than the osprey?

[illidur]

i wonder if it would make sense to add reverse thrust to the left jet engine... it doesn't really reverse it, but blows air sideways at an angle supposedly. so maybe it wouldn't be enough to stop a spin if the right engine died. but if it could then it would be safer than a normal heli with only 1 tail rotor.

[simplejack64]

thats impossible the torque would spin the airframe.....

[liakyh]

@simplejack64 not if the wing mounted ducted fans are providing asymmetrical to provide counter-torque

[simplejack64]

@liakyh you would need one duct fan facing backwards then and that would be completely implausible considering that no air would get into the engine

[dagulchachasophia]

no i think this is the lmfao helicopter

[danich45]

yes genius except the part where the guy on the streacher gets sucked into the jet engine intake . oops!

[st2hallock]

i want one

[osakanone]

Okay, that's cool as hell.

[paraphin]

is it a serious project? I lol'd crap out of my pants

[bwprh]

Lol that wouldn't fly probably it doesn't have a tail unless you want helicopter jet thing to fly in a circle go ahead

[HDaviator]

@bwprh

Have you ever seen a B2 bomber? Just curious.

[comanchio1976]

@bwprh There may be something within the disc spinning in the opposite direction...do you honestly think that the torque factor wouldnt have occurred to the top aeronautics experts at Boeing? But somehow it has, to a bunch of clueless Youtubers? (I include myself in that)

[ccecil3113]

@comanchio1976 It may also be possible to vary the thrust of the ducted fans to account for the torque. Of course unless the fans produce reverse thrust, hovering/VTOL would be impossible.

[GaunletofDestruction]

Rubs hands together........when do we get it?! ;D

[MadPyrotechnicus]

Government and military: "We don't need the Osprey, it isn't worth anything and costs too much!"

Boeing: "Wait a minute... What if we made an airplane, that could VTOL with a helicopter rotor on top?!"

Government and military: "That is about the most... GENIUS THING I've heard all day!"

[HeavensMercy]

This is actually a pretty good design the way this thing is built it could replace modern AWAC jets. tho...it would be a little risky to fly the first flaw i could see is the blade retraction system what if it jams? or if one of the blades breaks during flight? can the system automatically switch over to jet turbine propulsion? if it could to that then it might be a cool aircraft

[747wannabe21]

lol a lawn mower



[xis123]

nope....won't work...they never made osprey work and this looks even more complicated

[Kicker1JP]

Are DARPA ever going to build something that works? Like is a helicopter/plane really needed...it failed before so why do it again in this day and age...and don't get me started on the HV2 thing...good lord...a waste fuel! This seriously reminds me of 'Hammer Weapons Technology' in Iron man 2!

[HeavensMercy]

@Kicker1JP The V-22 osprey is a type of helicopter jet tho its killed more marines than Taliban soldiers, this could replace the V-22 and make soldiers life easier

[sentientagent]

darpa: the patent theft office. they don't come up with new shit, they just drag shit other people invented together. and then they take credit for it.

[AgrivatedKillah]

@sentientagent That's a blessing in disguise if you think of it.

If everybody sort of copied[and made modification to make things better, i.e: Japan]

There'd be more Technology.

More competition, means a faster rate of increasing the advancement of it.

Which is why the USA was behind in air support when it came to WW1, because they had patents, and nobody wanted to copy".

I don't agree exactly with copying, but some people even consider a modification as a copy.

[DarkZerosabre]

at the very beginning when its panning across the front of the plane, the front of it looks like a possum or a raccoon...

[skeederpeter]

Boeing already has a majority interest in the V-22. Why are they even wasting money on this project. It's like a junior high science project.

.... and I thought the Eurocopter X3 was ridiculous.

[Raven1180]

Leave me on the ground. No way I want to be pulled up so close to those turbines.

[dankardas]

Yeah, I thought about the torque problem too. Maybe they play with the reverse thrusters on one of the jet engines lol!

[matustrgina]

so fucking stupid design... who created that ? retarded monkey ?

[DE4THF1RE]

what is this? build something cool like a gundam

[megmag13]

Hm.. reminds me of Arnold Schwarzenegger's film, The 6:th Day. He is a cloned future helicopter pilot. The vehicles in the film have similarities to this one.

[6547bilberry]

The Osprey is terribly accident prone, very unstable during transition, just like the Harrier. Perhaps this design will be safer.

[thundertiger76]

the osprey does the same thing, nothing new here really !

[XCHUSKYXC]

its a multicopter: plane,helicopter,AWACS,V-22 osprey 4 in 1  #LOL

[AnToNhApPy1]

Nice animation, but this type of plane wont be build in real.

[flyKICKyo]

@AnToNhApPy1 actualy SEARCH jet chasing ufo....

in this video you can cleary see this aircraft beeing followed by a jet... :)

it looks very very verrrrrry similar
