Sikorsky will debut its latest S-97 Raider scout and attack compound helicopter at the AUSA 2015 Exposition that will take place from Oct 12-14 at Washington.
The first S-97 Raider technology demonstrator prototype which completed its maiden flight in last May, will be on static display. The first prototype intended for flight testing, will be followed by a second prototype later this year, for use as a demonstrator.
The Raider is capable of being developed into a multi mission helicopter, with the ability to carry six troops with external weapons.
The compound helicopter features rigid coaxial counter-rotating main rotors and a pusher propeller that enable it fly faster than conventional helicopters, with a cruise speed of upto 240 knots (276 mph).
The counter-rotating main rotors eliminate the need for a tail rotor, as the counter rotation cancels the opposing torque from each rotors. Also the rigid rotors enable the helicopter to respond to control inputs without lag.
The 5 tonne class helicopter has an all-composite fuselage, and is powered by a single General Electric YT706 turboshaft, rated at 1900 kW.
The program was launched in 2010, in response to U.S. Army's Armed Aerial Scout program intended to replace the Bell OH-58D Kiowa Warrior based on Sikorsky's X2 demonstrator. Army has since then shelved the AAS program, and selected existing fleet of Reserve and Air National Guard Boeing Apache attack helicopters for the scout role.
Army's current plan calls for a new light scout helicopter with introduction planned for 2030, part of the Future Vertical Lift (FVL) program to develop a family military helicopters for U.S. armed forces.
