The New Sikorsky S-76C++ Corporate Transport
The S-76C++, is currently available for order, after the S-76C+ line recently sold out. Deliveries of the S-76C++ commence in the 4th Qtr of 2005 and incorporates an upgraded engine, new VIP interior, health and usage monitoring system (HUMS) and new gearbox.
NEW S-76C++ Features Include:
Turbomeca Arriel 2S2 Engine Upgrade
The replacement 2S2 will provide a 5 to 6 percent increase in engine ratings, 350 to 450 lb increase in Category A takeoff gross weight at sea level 90F.
Improved Inlet Barrier Filter
In cooperation with Turbomeca, Sikorsky has also developed a new inlet barrier filtration (IBF) system that will reduce engine degradation without the power loss normally associated with barrier filters due to re-engineering of the intake flow.
New VIP interior
A new VIP interior designed by Heritage Aviation that offers an updated five-person seating arrangement encompassing a sleek, modern, leather interior, with a three-person aft-facing bench and two forward-facing captain’s chairs.
Quiet Zone Technology
Sikorsky's proprietary Quiet Zone Gearbox uses a proprietary technology to “superfinish” transmission gears, changing the shape of the gears and providing a mirror-like finish that lowers reduces noise in the cabin by 4 dB while increasing gear life and reliability. Using Keystone Helicopters’ latest Silencer technology, the new cabin will have the lowest interior noise levels of any helicopter in the S-76's class.
Health and Usage Monitoring System (HUMS)
The S-76C++ will also feature a Honeywell VXP HUMS to provide rotor track and balance, drive system monitoring and an option for high-speed shaft monitoring and with 25,000 flight hours proven capability is the best-in-class tool for cost management, efficient maintenance scheduling, and vibration based maintenance delivering improved safety, reliability and life-cycle cost reduction.
