Oct. 21, 2009, Fla. – Sikorsky Aircraft Corp.’s X2 Technology
demonstrator achieved a maximum speed of 106 knots in a recent test
flight at the Sikorsky Development Flight Center. Sikorsky is a
subsidiary of United Technologies Corp.
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 that a
helicopter can cruise comfortably at 250 knots while retaining such
desirable attributes as excellent low-speed handling, efficient
hovering, and a seamless and simple transition to high speed.
"As we continue to develop the X2 Technology features, the speed
milestones are of note, since we ultimately are looking to achieve
250-knot cruise speed,” said Jim Kagdis, Program Manager, Sikorsky
Advanced Programs. “The current phase of testing is aiming to take us
from 40 to 120 knots, and this latest flight signifies steady progress.
For potential customers who are interested in this particular
capability, it is another exciting step toward exceeding the average
top speed of a conventional helicopter, which is approximately 160 or
170 knots, and setting a new standard.”
The X2 Technology program began in 2005 when Sikorsky first
committed resources and full funding for the program’s development.
“The X2 Technology program is charting a new course in rotorcraft
aviation and has already attracted the attention of our customers who
appreciate the vision we have shared thus far. As the program
continues, we look forward to sharing the progress and bringing the
innovation to its fullest potential,” said Mark Miller, Sikorsky Vice
President of Research & Engineering.
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
