Sikorsky selects Hexcel’s composite materials

News International-French

19 Jan 2012

The subsidiary of United Technologies Corp. has selected Hexcel as a member of a newly-formed team that is building a next-generation helicopter, designated the S-97 RAIDER™ helicopter, for evaluation by the U.S. military.

Hexcel’s HexPly® prepregs and HexWeb® honeycomb core composite technologies will provide high strength and light weight properties to the aircraft’s structure and blades.


Sikorsky and its team suppliers are self-funding the design and manufacture of two S-97 RAIDER prototype aircraft for flight evaluation by the U.S. military. The program is currently in the advanced design stage. Sikorsky expects to achieve first flight in 2014.


The Raider aircraft program follows Sikorsky’s successful X2 Technology™ demonstrator aircraft, which in September 2010 achieved more than 250 knots flight speed, or twice the average cruise speed of a conventional helicopter. As an X2 aircraft design, the S-97 RAIDER helicopter will feature coaxial counter-rotating main rotors and a pusher propeller to provide improvements in maneuverability, hover efficiency, high/hot climate performance, and speed.


The X2™ design is scalable, opening up a variety of potential mission uses including combat search and rescue, armed aerial scout, medical evacuation, attack, special operations, VIP and offshore oil transport. Defined as a light tactical helicopter, the single-engine RAIDER aircraft will weigh in at 11,000-lbs maximum gross weight.
