MTU Aero Engines has confirmed the completion of the SAGE 4 engine demonstrator as part of the Clean Sky initiative.
The test program, developed and conducted by the German firm, comprised of 107 running hours, 500 test cycles and 30 starts on MTU Aero Engines’ development test stand.
MTU said SAGE 4 is based on the Pratt & Whitney’s PW1500G geared turbofan engine and it equipped the engine with compressor and turbine technology before carrying out a series of stress, vibration, rub-in and endurance tests.
“We’ve tested numerous new technologies, and many of them have been shown to be mature. Some of the hardware has reached the point of being ready to fly,” said Dr. Jörg Henne, senior vice-president engineering and technology at MTU.
SAGE 4, short for Sustainable And Green Engines, is one of five engine demonstrators part of the EU-funded aeronautics research program.
