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 didnt 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.
