Future Affordable Turbine Engine


The Future Affordable Turbine Engine is a US Army program for a 5,000-10,000-shp class turboshaft/turboprop for Future Vertical Lift aircraft and its Joint Multi Role precursor.

Design

To extend range and endurance and to increase hot-and-high payload and performance, it should reduce BSFC by 35%, reduce production/maintenance costs by 45%, improve power-to-weight by 80% and design life by 20% to more than 6,000 hours.

Development

In November 2011, GE was selected for $45 million over five years, to develop technologies including advanced aerodynamics, cooling configurations and improved materials; and rig tests to validate innovative components, leading up to a full system demonstration.
In 2017, following the successful tests of the engine’s compressor with the highest single-spool pressure ratio recorded, combustor with GE's most extensive use of CMCs allowing unprecedented high-temperature capability and weight reduction, and turbine rig tests, the first assembled engine completed testing after running 40 hours, reaching the program goals, before a second prototype began testing in 2018.
