Sikorsky Innovations has completed wind-tunnel testing of an active rotor system equipped with “high-authority” flaps, thus paving the way for improvements in noise, vibration–and, marginally, efficiency–on future rotorcraft.
Sikorsky Aircraft has named 35 suppliers participating in an industry-funded effort to build two prototype S-97 Raider helicopters for evaluation by the U.S. military.The Raider is a follow-on to the company’sX2 technology demonstratorwith coaxial contra-rotating main rotors and a pusher propeller.
Sikorsky said it will invest about 75 percent of the Raider program’s expected cost, with suppliers investing 25 percent. Last June, Sikorsky and General Electric signed an agreement under which GE Aviation will provide its CT7-8 engine for the Raider.
Sikorsky and Turkish Aerospace Industries (TAI) are discussing the possibility of jointly designing and developing a new light twin in the 8,000-pound-class. TAI would take the lead role in design, while Sikorsky would just support the program. The new helicopter would fill a gap in Sikorsky’s lineup, between the S-434 and the S-76.
Buoyed by steady and solid U.S. government and international work, Sikorsky is demonstrating strong hover performance in challenging economic conditions, and president Jeff Pino’s press conference yesterday morning was one of the more information-rich sessions here at Heli-Expo.
Sikorsky Innovations has completed rig testing of a hub-mounted vibration suppression system. The effort is jointly funded by Sikorsky and the U.S. Army’s Aviation Applied Technology Directorate. North Carolina-based Lord was also involved in the project. Sikorsky plans to test the technology on one of its helicopters in the next 12 months.
In a surprise announcement here yesterday, Stratford, Conn.-based Sikorsky Aircraft (Booth No. 1526) said that it had reached an agreement "in principle" to make a substantial minority investment in Eclipse Aerospace (Booth No. 6667).

Sikorsky will start certification testing on the S-434 light turbine single in January, thus postponing the target certification date to December next year.
Sikorsky is to start certification testing on the S-434 light single helicopter in January, thus postponing FAA certification to a targeted December 2011, AIN has learned. With this improved Schweizer 333, engineers already have completed some 50 hours of development flight tests to “mitigate risks and develop new systems,” according to company spokesperson.
Speaking yesterday at Heli-Expo 2010, Sikorsky president Jeffrey Pino found looking in the rear-view mirror a fair indicator of what’s to come, and as he put it, “It’s very good.
“We had a great year in 2009,” he said, pointing out $1.1 billion in sales from the Sikorsky Global Helicopters division, another $2 billion from Aerospace Services and a healthy $3.2 billion from Military Systems.
