Rolls-Royce unveils technology enhancements

Thursday, 1 March 2007

Rolls-Royce, the world-leading provider of power systems and services, has announced three new technology enhancements for Model 250 engines:

  • New Compressor Blisks. These blisks, engineered by Rolls-Royce for Model 250-C20B models, will eliminate the need for erosion coatings and result in lowered direct operating costs.
  • Reversionary Governor. Rolls-Royce expects to receive FAA certification by the end of 2007 on a new Full-Authority Digital Engine Control (FADEC) for the Series IV, Model 250-C47M engine, currently powering the MDHI 600N helicopter. This improvement will provide an increased operational benefit to the pilot, allowing continued flight in an automatic governed mode. This software upgrade is available to registered customers, primarily free-of-charge.
  • REM Gears. These new “super finish” gears allow improved reliability, lower direct operating costs and surface mating.

Scott Crislip, President Helicopters & Small Gas Turbine Engines for Rolls-Royce, said, “These improvements demonstrate that Rolls-Royce is constantly seeking advancements and working hard to maintain our status as a technology leader. We listen to our customers and work together to find solutions.”

In total, nearly 30,000 Model 250 engines have been produced, with approximately 16,000 remaining in service. It remains one of the highest-selling engines made by Rolls-Royce.
