Sikorsky video of the Sep. 15, 2010 test flight during which its X2 Technology coaxial-rotor helicopter demonstrator achieved its 250kt speed goal. Conventional helicopters cruise at around 150kt. The X2 reached 260kt in a shallow dive as is expected to exceed 250kt in level flight once a sail fairing is fitted between the upper and lower rotors to reduce drag further. X2 uses a single T800 engine to power both the rotors and the tail-mounted variable-pitch propeller, which provides forward thrust to enable the high speed. Other technologies include fly-by-wire flight controls and active vibration control. As the video opens you see a full-scale mockup of Sikorsky’s proposed X2 Light Tactical Helicopter in the hangar.

@cutiknet it only looks that way because the frame rate of the camera is matching up with the rotational speed of the blades. Merely a cinematic illusion.

Nice toy for millionaires no more.

So when do we get a RC version of this??? lol. I suspect it wouldn’t be too hard to do since most 3 and 4 channel RC helicopters employ the dual main rotor design.

@unatics design average ??????? WTF ?????? sorry i realise you are of course an aeronautical engineer yourself aren you !!

its a cross bread of a plane n helicopter. im making an r/c version of this 4 my science project

wow, awesome technology – helicopter, which levitate with almost not moving blades.
February 7th, 2012 at 3:04 pm
Wow ! Very nice!
February 7th, 2012 at 3:39 pm
Very nice!

Airwolf, eat your heat out!

I know they run choppers on piston engines. but I was wondering. if they put air intakes like on the side of an F1 car on either side of this thing. could they run a V6 in place of the turbine. then you could run it on unleaded. I could literally park that thing in my backyard with room to spare. and roll it into my garage.

Looks like a blimp

The real life Airwolf :p

No autorotation for this one..
February 7th, 2012 at 5:47 pm
Bad ass.

They need a better camera, and someone should fire the company DJ, he’s not so useful…. -__-

Im still impress how fast americans made prototyps..
There must be not realy funny inside cobine,Pilot say “wow that was amazing” and voice is shacing the same as his body) Lmao.

Looks a little weird, but we’ll get used to it when it halves the trip and lands on a dime. Wonder where the tilt-rotor fits into this picture? Obsolete? Wonder what price point they’ll be aiming for?

Awesome!!! Great job Sikorsky. Stay in the lead, like you always do…
February 7th, 2012 at 8:09 pm
@mercanaries3 hel yeah we beat aliens xD

The lettering “X2″ has the subtle Russian style…like Sukhoi. I guess that is the tradition of Sikorsky.

in 70 years we will have our own UFO
February 7th, 2012 at 9:58 pm
badass

@unatics This is a tech demonstrator. Its only purpose is to test the compound coaxial rotor system, which will no doubt be integrated into progressively larger aircraft.
