Helijet International Sikorsky S-76C Air Ambulance, Vancouver Island British Columbia. SCO 8875
The S-76C+ was produced until December 2005. It is equipped with twin Turboméca Arriel 2S1 engines with FADEC and a Honeywell EFIS suite.[5] The aircraft incorporates active noise suppression, vibration dampers and a composite main rotor. On January 3, 2006, the S-76 C++ replaced earlier models in production. It is powered by two Turbomeca Arriel 2S2 engines and incorporates an improved and quieter transmission as well as minor changes in the interior equipment and avionics. There were 92 orders for this model as of January 2006. The S-76 is of conventional configuration, with a four-bladed fully articulated main rotor and a four-bladed anti-torque rotor on the port side of the tailboom. Two turboshaft engines are located above the passenger cabin.[12] In the prototypes and initial production aircraft, these engines were Allison 250-C30s, a new version of the popular Allison 250 engine developed specially for the S-76, with a single-stage centrifugal compressor instead of the multi-stage axial/centrifugal compressor of earlier models of the engine, rated at 650 shp (480 kW) for take-off.[13] These engines are connected to the main rotor by the main gearbox, a three-stage unit with a bull gear as its final stage rather than the planetary gear used by previous generations of Sikorsky helicopters. This arrangement gave 30% fewer parts and lower costs than a more conventional design.[
