Improved turbine blade alloys enable the T56-3.5 engine to take advantage of technical advances that have improved capability significantly since this engine was first introduced in the 1950s. This improvement will allow operation of the turbine at higher inlet temperatures and reduced amounts ot cooling air. When combined with aerodynamic changes, fuel consumption could potentially be reduced by 7 % to 10 %, depending on the mission. The upgrade will be cost effective because many of the key components are routinely replaced at overhaul for the current T56. Potential savings and payback benefits will be derived from improved engine efficiency that is enabled by advanced materials and process technologies. Although these advances are typically targeted at next-generation propulsion systems, the potential tor benefiting current engines is also being evaluated. For example, near-term implementation as 'off-ramps' of bundled technologies into currently fielded engines could provide immediate benefits.
