Sikorsky X2 Technology helicopter achieves 250kt – Sep 2010
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.

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…
@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
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.
@zingerkid Granted this helicopter is tiny, but could the technology be used on a larger craft. I know the Osprey is MORE stable than it was originally, but has it been completely fixed — as in to the point where a similar design could be used for passengers? It could sure solve a lot of “short runway” problems in the third world.
They already downed 36 billion on Comanche, now they will build another tiny chopper which will turn out to have a too tiny hull to accomodate all the gizmos and weapons. As usually. this will be a joke chopter if compared to real choppers like- Ka 92 or Mil x1.
Music track was rather repetitive and monotonous.
@Calidris0 The problems with the Osprey have been fixed. Plus this is a tiny helicopter compared to the Osprey.
@unatics dude it broke the helicopter world speed record. kinda “new” technology that the russians “didn’t have decades ago”
pretty average if compared to russian choppers. This is tiny, with no retractable gears, can take no additional load,. What is the purpose of it, just to demonstrate technology that russians had decades ago? American flying machines are becoming smaller and smaller, and new products are created more enad more rarely. Designwise also average.
Looks like a possible replacement for the Osprey that keeps having problems. Bring the two rotors in and stack them, then use a separate rotor to propel forward.
Retreating blade stall not a problem on a co-axial i guess, very nice.
Great!!!
@newscruzer1 definitely feet per minute… 700 feet per second would be 42,000 feet per minute, which isn’t unachievable… for a fighter jet or spacecraft lol
@newscruzer1 Climb rate not airspeed.
Good video and great accomplihment..but that headache music/noise was abnoxious to say the least.
Good, this will make sure we win the battle of LA.
I heard them report 700 ft. per. min., somehow I thought it would of been per sec.
700 ft. per min.just doesn’t seem right, but then i could very well be totally wrong, if so didn’t mean anything by it, just courous is all.
This is some kind of machine, very impressive.
I’m french and I love USA and USA technology especially in aviation subjects. I finished my career as an instructor on Boeing, Douglas and Airbus aicraft (not Tristar pardon me) and retiered presently. Many thanks for this beautiful video
So, two contra-rotating coaxial rotors, can do away with the tail rotor. Then a prop is used for forward propulsion.
Seems like a cross between a helicopter and autogyro.
It can’t lift anything but DAMN!!!!! THAT’S SWEET!!!!!
Fantastic job Sikorsky. What beautiful lines and grace. Would adding short stubby wings like on the Bell 222 give any added benefit to the aircraft as far as lift or stability? While it looks like you are right on with the design just an observation to enhance speed with stability may be achieved like the wing fairings of a jet.
Again outstanding work Sikorsky
