The US Air Force Research Laboratory-funded adaptive versatile engine technology (ADVENT) research programme has received the fan system component from Rolls-Royce.
The air force will now carry out tests on the adaptive fan system, focusing on variable-cycle engine performance.
Variable-cycle engine performance is a critical component for achieving high-thrust capability for take-off and manoeuvring that reduces fuel consumption for long-range and loiter operations.
ADVENT is part of the government's versatile affordable advanced turbine engines initiative to advance turbine engine technology for military and commercial aviation.
AFRL had awarded $296m contract to Rolls-Royce in 2007 to develop technologies for an adaptive engine architecture that creates 25% reduction in average fuel consumption and reduced temperature cooling air for thermal management.
USAF will select a contractor for phase 2 of the programme in late 2009 for final design, component testing and full engine manufacture.
Engine demonstrator testing will take place in 2012.
