Sikorsky S-97 Raider
The Sikorsky S-97 Raider is a high-speed scout and attack compound helicopter based on the Advancing Blade Concept (ABC) with a coaxial rotor system under development by Sikorsky Aircraft. Sikorsky planned to offer it for the United States Army's Armed Aerial Scout program, along with other possible uses. The S-97 made its maiden flight on 22 May 2015.
Sikorsky plans to build two prototypes of the S-97 as demonstrators. One prototype (P1) will be used for flight testing, while the second (P2) is planned for use as a demonstrator.[9] The first prototype was planned to fly in late 2013 or early 2014.[7][10] Sikorsky started construction of the two prototypes in October 2012.[11] In September 2013, Sikorsky began final assembly of the first S-97 following delivery of the single-piece, all-composite fuselage by Aurora Flight Sciences.[12] In February 2014, construction of the first S-97 prototype was one-quarter complete. Simulated bird strikes testing had been conducted on the fuselage at speeds of up to 235 kn (435 km/h; 270 mph), the S-97's expected maximum flight speed. Drop tests were also performed to ensure the fuel tanks' safety in the event of a crash. Sikorsky is exploring civil applications for the S-97, such as transporting personnel between offshore oil platforms.
