The H-92 Superhawk is the military variant of

190-738: A joint-venture with Tata Advanced Systems for S-92 manufacturing in India for export and domestic markets. A US$ 200 million manufacturing plant will be operational in Hyderabad by 2010. Initially, TASL will supply the complete cabins for the S-92 to Sikorsky. The first cabin was delivered in November 2010. The S-92 is multi-purpose helicopter powered by twin GE CT7-8A turboshaft engines and has an aluminum airframe and some composite components. The four-bladed fully articulated composite main rotor blade

228-514: A key requirement of the Nordic Standard Helicopter Program (NSHP) for shipboard stowage. The lengthening of the fuselage and shortening of the tail pylon shifted the aircraft center of gravity (CG) forward, permitting a more level attitude in flight. The longer fuselage allowed for an additional row of three seats, as well as a larger passenger door option for Search and Rescue (SAR) customers. Sikorsky incorporated

266-505: A need for aircraft such as the S-92 with sufficient capability. Sikorsky Aircraft first displayed a S-92 mockup of the planned helicopter in 1992. The S-92 was to be offered for sale beginning in 1993, but due to a decline in the international market for helicopters, this was delayed. In 1995 Sikorsky formed Team S-92 with international partners and launched the helicopter program at the Paris Airshow that year. Sikorsky developed

304-429: A production decision in 2024. In addition to 3,000-shp output, the targets for AATE were a 25% reduction in fuel consumption (less than 0.347 lb/(hp⋅h), 211 g/kWh), a 65% improvement in power to weight (more than 6.5 hp/lb, 10.7 kW/kg), a 20% improvement in design life (more than 6000 hours and 15000 cycles), a 35% reduction in production (less than $ 650k per engine) and maintenance cost , and

456-446: Is used in the exhaust stream downstream of the gas generator to extract power. Although the dual-spool design allows each compressor stage to run in their optimal ranges, it makes the machine more complex. The Advanced Turbine Engine Company (ATEC) is a 50/50 joint venture created in 2007 between Honeywell Aerospace and Pratt & Whitney Military Engines. ATEC completed a Core Engine (High Pressure system only) test in mid-2011 on

494-558: Is wider and has a longer radius than the Sikorsky S-70. The tapered blade tip sweeps back and angles downward to reduce noise and increase lift. Most of the rotor system components aside from the blades are titanium. The S-92 features an active vibration control system, using vibration sensors and structurally mounted force generators to increase flight comfort and lower acoustic levels to below certification requirements. A 2008 study by Norway's Flymedisinsk Institute found that

532-667: The ATEC joint venture to develop the T900 , while GE Aviation builds the T901 . In February 2019, the US Army selected the GE T901 as the winner of the program. In December 2006, the U.S. Army's Aviation Applied Technology Directorate (AATD) solicited proposals for the 3000 shp Advanced Affordable Turbine Engine (AATE) free-turbine turboshaft to replace the GE T700 that currently power
