THE USAF Research Laboratory (AFRL) has started initial testing of the Responsive Open Source Engine (ROSE) at Wright-Patterson Air Force Base, Ohio. Testing began in early November and follows a new, ultra-responsive approach to turbine engine development. The AFRL is joined by an array of organisations on the programme, including the Aerospace Systems Directorate (ASD), which is currently developing scramjet engines, alternative fuels, unmanned vehicles, hypersonic platforms, collision avoidance and aircraft energy optimisation. The ASD is leading the ROSE programme, which is the first turbine engine to be designed, assembled and tested exclusively in-house, Within 13 months, the ASD has progressed ROSE from a concept to initial testing.
