A great idea for the us military and army this new helicopter will be a great boost to us military power. The Sikorsky S-97 Raider is a proposed high-speed scout and attack helicopter, 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.[3] Development[edit] One prototype will be used for flight testing, while the second is planned for use as a demonstrator. The first prototype was planned to fly in late 2013 or early 2014 near the release of the Armed Aerial Scout Request for Proposals.[5][8] Sikorsky started construction of the two prototypes in October 2012.[9] In September 2013, Sikorsky began final assembly of the first S-97 Raider following delivery of the single-piece, all-composite fuselage by Aurora Flight Sciences.[10] Sikorsky is also using the technology and design process,[11] along with partner Boeing, as a basis from which to develop a high-speed rigid rotor co-axial design called SB-1 Defiant for the army's Joint Multi-Role Technology Demonstrator (JMR TD) programme. The JMR TD is the precursor to the army's estimated USD100 billion Future Vertical Lift (FVL) programme, which is meant to replace the army's UH-60 Black Hawk utility helicopters and AH-64 Apache attack helicopters.[12] The first Raider is scheduled to fly at the end of 2014. One will be used for tests, and the other for demonstrations. Sikorsky wants to offer the S-97 for the AAS program, but also wants the helicopter to fly before the Army makes its downselect. Sikorsky invested $150 million and its 54 suppliers[13] (who provide 90% of the parts)[11] are spending the remainder of a total of $200 million on two prototypes, but production models must meet the $15 million unit cost budgeted for the program. The Army was still deciding whether or not to proceed with the competition or extend the service life of the OH-58 Kiowa.[14] The Army ended the AAS program in late 2013.[15] In February 2014, construction of the first S-97 prototype airframe 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 safety of the fuel tanks in the event of a crash. Sikorsky is exploring civil applications for the S-97, such as transporting personnel between offshore oil platforms.[16] Budget projections for FY 2015 include a measure to retire the U.S. Army's OH-58 Kiowa fleet and remove AH-64 Apache attack helicopters from U.S. Army Reserve and U.S. Army National Guard control and transfer them to the active Army to take the place of the aerial scout role. Sikorsky has suggested the possibility of buying the S-97 Raider as a replacement for the loss of Apaches to fulfill armed helicopter needs.[17] On 5 May 2014, Sikorsky opened the production hangar to the S-97 during the rollout of the CH-53K King Stallion. The company plans to fly the aircraft by 1 December 2014. The mostly composite airframe was almost fully assembled and included wiring and some avionics systems; still missing was the transmission, drive train, engine, coaxial rotor, and pusher propeller. The wiring is to be completed to power-on electrical systems by the end of May. The S-97's first military customer is aimed to be the U.S. Special Operations Command to replace the MH-6M Little Bird.[18] Unspecified foreign militaries have shown interest in the S-97 design. With the U.S. Army's AAS program on hold (but not cancelled outright), it may be difficult to get approval for export for a next-generation helicopter if the American military does not yet have it. The Raider is a prototype, so the first customer would need to fund and support a production development program.[19] Its avionics were powered on in June 2014, and Sikorsky expected first flight the same year,[20] with rollout on 2 October 2014.[21][13][22][11] Design The S-97 design includes variable speed[23] coaxial main rotors and a variable pitch pusher propeller,[4] making the S-97 a compound helicopter. The S-97 will be capable of carrying up to six passengers, in addition to a flight crew of two in a side-by-side cockpit.[4] However, the production S-97 is projected to be capable of flying with either one or two pilots, or autonomously.[3] Space for a targeting sensor has been reserved, however it will not be installed in the prototype aircraft.[3] Based on the technology from the Sikorsky X2 demonstrator, the prototype S-97s will be powered by a General Electric YT706 turboshaft (the same engine used on the UH-60M Black Hawk),[3] however a more powerful engine, developed under the Improved Turbine Engine Program, is expected to become available.[3] Compared to the OH-58D Kiowa, the S-97 has significantly increased performance goals, such as cruising speeds upwards of 200 knots[8] and turning at three times the force of gravity.[24]
