Sikorsky X2 Envelope Expansion Continues

Demonstrator Tops 100-Knot Speed Milestone

Sikorsky's said Thursday that its X2 Technology demonstrator achieved a significant milestone in a recent flight test, reaching a maximum speed of 106 knots. The test was conducted at the Sikorsky Development Flight Center in West Palm Beach, Florida.

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."

Sikorsky has been developing the X2 Technology since 2005. "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.
