Advanced Helo Concept In Development For Three Years
After three years in development and experimental testing, the
first flight of Sikorsky Aircraft Corp.’s X2 Technology
Demonstrator is "within reach," James Kagdis, Program Manager,
Advanced Programs, said this week at the Farnborough International
The X2 Technology Demonstrator has accomplished more than 14
hours of ground run testing and is progressing toward first
"The Demonstrator has completed Phase 2 of ground run testing
with blades on, and is in final build-up for first flight," Kagdis
said. "Customer feedback since tells us that X2 Technology has the
potential to be applied to a broad range of missions. We are
excited at the prospects of transforming vertical flight through
this innovative Technology."
Sikorsky’s Schweizer Aircraft Corp. rapid-prototyping
facility in Horseheads, NY is preparing the X2 Technology
Demonstrator for its first flight.
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 comfortably at 250 knots, while
retaining such desirable helicopter attributes as excellent low
speed handling, efficient hovering and autorotation safety, and a
seamless and simple transition to high speed.
The X2 Technology Demonstrator features a number of advanced
features, including fly-by-wire flight controls, counter-rotating
rigid rotor blades, and an integrated auxiliary propulsion system.
Hub drag reduction and active vibration control are also employed
on the X2.
Sikorsky Aircraft first announced the initiative to develop an
integrated suite of technologies called X2 Technology in June 2005.
After a series of early achievements, the helomaker was forced to
stall development in late 2006 due to a 10-week machinists strike
before starting anew in 2007. The project is
funded solely by Sikorsky.
