Sikorsky Announces New S-76 Models

The first of the new models, the S-76C++, is currently available for order, after the S-76C+ line recently sold out. Sikorsky anticipates deliveries late this year of the new model, which incorporates an upgraded engine, new VIP interior, health and usage monitoring system (HUMS) and new gearbox. Pricing on the S-76C++ remains the same as the S-76C+, according to Sikorsky.

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.

Scheduled for delivery in mid-2008, the S-76D will build upon the upgrades slated immediately for the C++ by offering additional product improvements. The S-76D is expected to increase high-and-hot lifting capability by 1,400 pounds thanks to the new engine.

NEW S-76D Features Include:

NEW Pratt & Whitney Canada PW210S Engine

The PW210S, tailored for the specific needs of S-76D customers, will encompass the latest turbine technologies to provide the best match of power, range, payload, and fuel consumption. The Category A hot takeoff capability will increase by nearly 1,000 pounds, while maintaining the range advantage of the S-76C+.

NEW Composite Main Rotor Blade

The new blade design will draw on the RAH-66 Comanche's "Generation 3" rotor, and will be a scaled-down derivative of the newer-generation aerofoil used on the upgraded UH-60M. Not only will the blade meet the latest FAA safety standards for damage tolerance, but will increase hover performance and cruise efficiency, with almost 300 additional pounds capability for Cat A hot take-off performance and 50 additional nautical miles range compared with today's main rotor blade.

NEW Rotorcraft Icing Protection System (RIPS)

The S-76D will incorporate the same rotorcraft icing protection system (RIPS) currently being certified on the S-92, and will provide the ability to launch into known icing conditions, maximizing the S-76D's dispatch reliability. A state-of-the-art controller for the electrical deiced main and tail rotor blades will minimize the system's power consumption and maximize its reliability.

NEW Quiet Tail Rotor

New Quiet Tail Rotor - The S-76D will add even more comfort and environmentally friendly efficiencies with the New Quiet Tail Rotor. The New Quiet Tail Rotor will produce 2 dBA exterior noise reduction on takeoff, a 1.5 dBA exterior noise reduction on flyover, and no change in performance, handling or sideward flight capability.

NEW Avionics Suite

Sikorsky is currently holding a competition for the S-76D avionics supplier to provide a modern, highly integrated avionics system designed to the latest FAA/JAA requirements. The S-76D cockpit will feature large, flat-panel LCDs that will reduce pilot workload and improve cockpit visibility; entrants include L3, Thales, Honeywell, Rockwell Collins and others. The avionics package is expected to be announced within the next few months.

NEW Streamlined Exterior.

The S-76 didn’t get its looks by chance. The original design requirement, set by the offshore oil operators, was to move twelve people, long distances, as efficiently as possible. That has remained a goal for the S-76 team at Sikorsky which is why the S-76D is to get a new feature a new streamlined exterior.

These latest announcement’s represents Sikorsky’s commitment to our customers to improve the S-76 to give more power, speed, payload, range, lifting power and lower maintenance costs.
