Crystal ball-gazing the X2′s military future

With theSikorsky X2 prototype achieving first flight yesterday, it’s a good time to discussits military potential.

The X2 isdesigned with a coaxial main rotor and an aft pusher propeller in order to breakthe conventional helicopter’s roughly 170-knot/hour speed barrier.

And itsfly-by-wire controls and modern avionics are supposed to defeat the highvibration and high workload levels that doomed Sikorsky’s last attempt in the1970s with the XH-59A advancing blade concept.

Sikorskybusiness development director Jim Kagdis, a veteran of the RAH-66 Comanche,spoke with me yesterday about the military vision for the X2.

Kagdisidentified three potential missions:

 

  1. Peer escort for the BellBoeing MV-22, replacing the slower AH-1W/Z Cobra. (Interestingly, Lt Gen David Trautman, US Marine Corps chief of aviation, told me last month that the MV-22 no longer required a high-speed escort.)
  2. Carrier-based antisubmarine warfare helicopter, replacing Sikorsky’s SH-60. As Kagdis says, when an enemy sub is on the loose near the battle group, “speed really helps you get their faster”.
  3. Combat support for special forces in urban environments

 

I was alittle surprised Kagdis limited his vision to fairly niche roles for the X2. Wouldn’tSikorsky want to offer the X2 for the emerging ‘Joint Multi-Role’ (JMR)requirement to develop a single aircraft after 2020 worthy of replacing theBoeing AH-64 Apache and the Sikorsky UH-60 Black Hawk? As you can imagine, thisis the Holy Grail for the world’s helicopter industry after the next decade.

Kagdisreplied that it was all about the requirement. “If the customer’s demands areas interested in a requirement that includes significant or greater speeds thanwe have today with the same hover performance as a conventional helicopter,this [the X2] becomes a competitor,” Kagdis said.

    Unfortunately the coolest helicopter technology goes black and we rarely get to see a civilian derivitive. And this thing is waaay up there on the cool-o-meter.

    Congrats to the X2 team and good luck, Mr. Kagdis.

    I’m disappointed with Flight Global once again. For a news magazine in the aviation business, with some technical content, things like the following make me want to scream:

    “The X2 is designed with a coaxial main rotor and an aft pusher propeller in order to break the conventional helicopter’s roughly 170-knot/hour speed barrier.”

    Knot/hour?!?!?!?!? The knot is a unit of speed (nautical miles per hour), so adding another “per hour” makes it a unit of acceleration!

    Come on people, get it right!

    It’s fixed! Please calm down! I’ve never claimed to be a technical expert. I went to journalism school!

    Several completely random thoughts:
    The AH-56 returns. The X-2 is very small. I wonder if problems will occur with rotor blades as the system scales up.
    I know problems can be solved. Witness the F-35B lift fan vs the AFV-12.
    Replacing the AH-64 and the UH-60? An American Hind? Man that would be cool.

    At least somebody in the US has the guts to do something on their own. Pretty spectacular given the lackluster market.
