Posted by John McHaleWEST PALM BEACH, Fla., 26 May 2010. Sikorsky Aircraft Corp.'s X2 Technology demonstrator achieved a speed of 181 knots in a test flight at the Sikorsky Development Flight Center. 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 Sikorsky officials say."The X2 Technology demonstrator today exceeded average helicopter speeds of a conventional helicopter, generally 160-170 knots," says Jim Kagdis, program manager, Sikorsky Advanced Programs. "The demonstrator is proving out the technologies very well, from the active vibration control system to the fly-by-wire controls. There are no show stoppers here so far, and now the program turns a corner, as this completes phase three of four. We are flying forward to the 250-knot cruise speed."Among the technologies the X2 Technology demonstrator employs are:- fly-by-wire flight controls;- counter-rotating rigid rotor blades;- hub drag reduction;- active vibration control; and- an integrated auxiliary propulsion system.The X2 Technology program began in 2005 when Sikorsky first committed resources and full funding for the program's development.
