Sikorsky Aircraft Corp. unveiled the first of two S-97 Raider helicopter prototypes earlier this month in collaboration with LORD Corp.
Sikorsky teamed with specialized companies in the rotorcraft industry to develop this follow-up to its successful X2 Technology demonstrator aircraft. Designed for military missions, including special operations, the S-97 Raider features next-generation technologies in an aerial scout aircraft, capable of carrying six troops and external weapons.
These activities in the S-97 RAIDER program’s test flight phase were made possible by LORD Corporation’s elastomeric bearings and Active Vibration Control System, which enable the aircraft to demonstrate significant improvements to a conventional helicopter’s performance. Sikorsky also uses LORD UltraConductive solutions across its platform for direct lightning strike protection, grounding of fasteners, and ease of manufacturability.
“The S-97 new coaxial rotor system presented an opportunity for LORD to feature a solution utilizing our core technologies,” said Karen Doehrel, staff program manager, LORD Corporation. “The design of our elastomeric bearings meets the very specific requirements of the S-97 rotor system and allows the rotor blades to pitch, which gives the pilot control over the aircraft. Our Active Vibration Control System keeps vibration levels down to a minimum.”
“When Sikorsky launched the Raider program four years ago, it issued a challenge to industry experts to join us on a mission to develop and produce an aircraft with revolutionary capabilities that are above and beyond existing technologies,” said Mark Miller, vice president of Sikorsky research and engineering. “LORD Corporation accepted that challenge as one of 53 critical partners on this program, and has delivered on its promise to support the mission. Today, we stand as a solid industry team introducing the next generation of military aircraft.”
The S-97 Raider will feature coaxial counter-rotating main rotors and a pusher propeller that will provide dramatic improvements in maneuverability, hover efficiency, high/hot climate performance, and speed. Sikorsky will offer the Raider aircraft as a replacement for the U.S. Army’s OH-58D Kiowa Warrior helicopter fleet based on the Army’s future operational and financial priorities.
