Today, the turbofan engine has found a home on practically all
jet-propelled aircraft. However, the ambitious emission goals of ACARE 2020
cannot be fully met with the current turbofan concepts and industry majors need
to look elsewhere to find a viable solution.
A high
bypass engine is the key to reducing both fuel consumption and noise and
developments are underfoot aimed to raise the bypass ratio above ten and optimize
individual components for better aerodynamic efficiency.
