Sikorsky S-76 Specs, Interior, and Price – Sikorsky S-76 is a medium-sized multi-role versatile helicopter manufactured by Sikorsky Aircraft Corporation (SAC) di Stratford, US. Initially this helicopter was designed and developed for CHC Helicopter Corporation, Canada. Sikorsky S-76 can carry out various types of operations, including executive passenger (VIP) transportation, emergency medical services (EMS), search and rescue operations (SAR) and passenger and material offshore transportation. The first Sikorsky S-76 flight took place on March 13, 1977.
The S-76A is the first model in the S-76 series. About 284 S-76A helicopters have been produced. The second variant, the S-76A Utility, is an advanced version of the S-76A. The S-76A Utility is equipped with reinforced sliding doors and floors.
The S-76A + variant has two turbo Turbomeca Arriel 1S engines. The all-weather transportation model, the S-76A Mk II variant comes from the S-76A + by completing the last helicopter with a powerful engine.
The S-76B is equipped with two Pratt and Whitney PT6B-36A or PT6B-36B turbo shaft engines. Increased engine power capacity to 539kW led to the development of the S-76C.
Another variant, the S-76C +, was developed by upgrading the S-76B engine with full authority digital engine control (FADEC). The S-76C + is powered by the Arriel 2S1 turboshafts that are enhanced.
Another new variant, the S-76C ++, was developed by overhauling the engine, avionics and a new gearbox from the S-76C. The presence of a powerful engine in the S-76C ++ increases takeoff weight by 450 pounds. The S-76C ++ also includes a new cabin for VIP transportation.
S-76C ++, which features a better and quieter air intake and transmission filter, launched later. It is equipped with improved interior and electronic equipment. Production of S-76C ++ was completed in January 2006. This helicopter is powered by Turboméca Arriel 2S2 turbo shaft engine.
The S-76D is equipped with Pratt and Whitney 210S engines. The dual engine controlled by FADEC can generate power of around 1,050 hp. The Active Vibration Control System (AVCS) and four bladed composite main rotor are installed for smooth operation.
Rotation per minute (rpm) rotor adjusted itself. Higher Rpm is applied during takeoff and lower rpm settings are applied to increase roaming range.
The Turbomeca Arriel 2S2 engine has a simple design consisting of five modules. This provides simpler maintenance and reduces operating costs through optimized acceleration mode. The Arriel 2S2 turbo shaft engine produces 6% more power than the Arriel 2S1 turbo shaft engine. It is also equipped with a dual channel electronic engine control unit (EECU), which measures fuel, ignition time and other parameters. The durability of Arriel 2S2 is 3,000 hours.
Sikorsky S-76 can fly with a maximum speed of 287km / hour. The ferry range and helicopter service ceilings are 639 km and 4,572 m, respectively. The maximum take-off weight of the S-76 is 5,306kg while the empty weight is 3,177kg.
The helicopter also has a spacious cabin interior, AVCS, reduced interior noise, two cabin doors with pop-up windows and two cockpit doors.
The cockpit-mounted avionics suite S-76C ++ includes a Honeywell four-tube electronic flight instrument system (EFIS), fully four-axis autopilot, integrated instrument display system (IIDS) and an improved Honeywell remote proximity warning system (EGPWS) .
The cockpit S-76D is equipped with avionics that include the Thales Top Deck avionics system, full four axis pairing autopilot, EGPWS, traffic collision avoidance system (TCAS1), Honeywell Primus 660 weather radar, system health monitoring (HUMS), Thales digital map and Collins Pro Line 21 radio suites.
The Sikorsky and Rescue and Rescue Bureau of the Chinese Ministry of Transportation signed a contract for four Sikorsky S-76D search and rescue helicopters in March 2013. Options for four helicopters were added in July 2013.
In March 2013, Bristow Group signed an agreement with Sikorsky for up to 26 S-76D helicopters. The first helicopter was sent in December 2013.
Arkansas Children's Hospital (ACH) signed a contract with Sikorsky for two S-76D helicopters in March 2013. Mitsubishi Corporation ordered 11 S-76D helicopters for the Japan Coast Guard (JCG) in June 2013. The first helicopter was delivered in mid-2014.

How come all the specs are in Metric? I guess they are not interested in American Business.
