Sikorsky Aircraft’s X2 technology demonstrator achieved a forward speed of 181 knots on a test flight today at the Sikorsky Development Flight Center in West Palm Beach, Fla. The contra-rotating coaxial rotor prototype is designed to demonstrate that a helicopter can cruise at up to 250 knots while retaining excellent low-speed handling and efficient hovering characteristics, as well as a seamless and simple transition to high speed.
Cutting-edge research takes an enormous amount of time and while the BA609 tiltrotor still shows signs of life, it may end up a solely AgustaWestland project. Sikorsky’s X2 compound helicopter hasn’t broken any speed records, yet, but it remains a fascinating program.
The Light Helicopter Turbine Engine Company (LHTec), a joint venture between Honeywell and Rolls-Royce, has entered into a 10-year agreement with Aerospace Products International under which API will be the exclusive distributor of CTS800 spare parts globally.

Sikorsky’s futuristic X2 is up and flying, but it could be a decade before the technology is applied commercially, according to program manager Jim Kagdis.
Sikorsky has nearly finished building its X2 coaxial compound helicopter demonstrator in Elmira, N.Y. According to Jim Kagdis, Sikorsky’s manager of advanced programs, additional ground tests are needed, but first flight is “within arm’s reach.” He declined to provide a specific time period.
Thirty-eight months after Sikorsky’s formal announcement of the X2 “technology demonstrator,” the compound helicopter made its first flight yesterday at the Sikorsky-Schweizer rapid prototyping facility in Horseheads, N.Y. During the 30-minute flight, Sikorsky chief test pilot Kevin Bredenbeck conducted slow forward flight, hover and hover turn maneuvers.
Helicopter manufacturer Sikorsky (Hall 4 Stand F14) has nearly finished building its X2 coaxial compound helicopter demonstrator in Elmira, New York. Although additional ground tests are needed there, first flight is “within arm’s reach,” according to Jim Kagdis, Sikorsky’s manager of advanced programs. He would not commit to a specific time period, however. The X2 program is entirely funded by Sikorsky.
Sikorsky’s X2 technology dem-onstrator could fly by year-end, according to Peter Grant, Sikorsky’s director of advanced programs. The X2 is a coaxial rigid-rotor compound helicopter designed to achieve forward speeds up to 250 knots, and at that clip it would become the world’s fastest helicopter. The current helicopter speed record of 217 knots (set by a Westland Lynx) has stood for more than 20 years.
Honeywell announced that its HTS900 turboshaft engine, yet to be certified, is already getting an upgrade. The engine has been fitted with a new dual-centrifugal compressor that Honeywell said provides increased thermodynamic power capability and reduced fuel consumption, and at the same time allows for future engine growth within the same engine footprint.
