Engine output peaks at , with of torque at that peak, which occurs at 3,000 rpm. The turbine can provide torque in excess of at significantly lower RPMs. The engine weighs approximately and occupies a volume of , measuring . The engine can use a variety of fuels, including
jet fuel,
gasoline,
diesel and
marine diesel. The engine is a three-shaft machine composed of five sub-modules: • Recuperator – a fixed cylindrical
regenerative heat exchanger that extracts waste heat from the exhaust gases and uses it to preheat the compressed air • Rotating Gas Producer – the five-stage, dual-spool compressor which achieves a 14.5:1 compression ratio at full power, driven by the compressor turbine, which operates with a maximum turbine inlet temperature of • Accessory Gearbox –
bevel gears that extract from the high-pressure spool to operate the fuel control unit, starter, oil pump, and vehicle hydraulic pump • Power Turbines – the first stage of the two-stage power turbine is driven by a variable-geometry nozzle to improve efficiency • Reduction Gearbox – reduces power turboshaft speed ==History==
