X2 TECHNOLOGY™ Light Tactical Helicopter Concept

May 4, 2009, Nashville, TN – Sikorsky Aircraft Corp. today unveiled its X2 TECHNOLOGY™ Light Tactical Helicopter (LTH) design at the Army Aviation Association of America annual convention. The new mockup reflects Sikorsky’s concept for potential military application of the high-speed enabling X2 TECHNOLOGY. Sikorsky is a subsidiary of United Technologies Corp. (NYSE:UTX).
 
“These technologies can potentially bring new rotorcraft capabilities that, to date, have been unachievable by the industry,” said Sikorsky President Jeffrey P. Pino. “In addition to doubling the speed of helicopters, this technology can improve hot/high performance, maneuverability and low acoustic signature. Sikorsky’s Light Tactical Helicopter concept demonstrates a way to package these capabilities into an airframe that is tailored to meet a range of military missions.”
 
The X2 TECHNOLOGY Light Tactical Helicopter multi-mission capabilities will meet both regular U.S. Army and Special Operations future requirements in a variety of combat roles. Sikorsky Aircraft has invested in the LTH concept to illustrate its commitment to developing future capabilities that are achievable and affordable. X2 TECHNOLOGY is scalable to a variety of military missions including assault, armed reconnaissance, close-air support and combat search and rescue, and unmanned applications.

Sikorsky Aircraft announced an initiative in June 2005 to develop an integrated suite of technologies called X2 TECHNOLOGY. The technology demonstrator aircraft, which achieved first flight in August 2008, is progressing toward the milestone of achieving 250 knot cruise speed. The project is funded entirely by Sikorsky.
 
The X2 TECHNOLOGY demonstrator combines an integrated suite of technologies intended to advance the state-of-the-art, counter-rotating coaxial rotor helicopter. It is designed to demonstrate a helicopter can cruise at 250 knots, while retaining such desirable helicopter attributes as excellent low speed handling, efficient hovering, autorotation safety, and a seamless and simple transition to high speed.
 
Among the innovative technologies the X2 TECHNOLOGY demonstrator employs are:
• Fly-by-wire flight controls
• Counter-rotating rigid rotor blades
• Hub drag reduction
• Active vibration control
• Integrated auxiliary propulsion system
