The PW1217G for the 90-seat MRJ90 flew on a specially designed stub wing aboard Pratt Whitney’s Boeing 747SP flying test bed from Pratt Whitney’s Mirabel Aerospace Centre in Canada.
Tests to validate the engine's fuel efficiency, durability and other performance metrics, will be conducted over roughly one year so they will... read more »
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.
A new development that... read more »
