Open Rotor Engines Advanced Technologies II (OREAT II)
Date du début: 1 déc. 2011, Date de fin: 31 juil. 2013,
"A principal contributor to affordable and sustainable public air transportation will be the introduction of more fuel-efficient propulsion systems, one of which is the Open Rotor Engine concept. Unlike turbofans, open rotors must vary blade pitch to accommodate power and aircraft speed range, so a key element to the viability of the concept is the actuation and control of the blade pitch via the ...
