Rolls-Royce, the global power systems company, and the U.S. Air Force are conducting flight tests for an enhancement for the T56 turboprop engine, which powers the C-130H transport aircraft.
The Series 3.5 Engine Enhancement is designed to deliver fuel savings and reliability improvements, resulting in improved life cycle costs.
The first C-130H test aircraft began flying recently at Edwards Air Force Base, Calif.
Rolls-Royce says the Series 3.5 Engine Enhancement has already demonstrated greater than 8-percent fuel burn improvement in ground tests, using proven technologies from other Rolls-Royce commercial and military engines, including new blade and vane materials and advanced turbine airfoil aerodynamic designs. The Series 3.5 will also improve performance in ‘hot and high’ conditions.
“We look forward to carrying out flight tests to confirm what we have already demonstrated in the test cell – significant savings in fuel costs, improved reliability and performance,” said Tom Bell, president of Customer Business-Defense for Rolls-Royce. “Rolls-Royce has invested to help the U.S. Air Force and other operators around the world meet their goal of reducing fuel costs, while also extending the life of the C-130 fleet and potentially saving billions of dollars.”
The Series 3.5 Engine Enhancement program is expected to enable the Air Force to continue to operate its C-130H fleet until 2040, and an Air Force analysis estimated its long-term savings from the Series 3.5 enhancements could reach $2 billion.
The engine improvements can be accomplished as part of a conventional engine overhaul, and do not require any aircraft or engine control system modifications. Each C-130 aircraft has four Rolls-Royce T56 engines, with approximately 220 C-130H models eligible for upgrades.
The Series 3.5 program can help the Air Force to achieve its goal of reducing consumption of aviation fuel by 10 percent by 2015.
