Both the IAE V2500 and CFM56 families of engines are widely recognized as successful turbofans in the aviation industry. The IAE V2500, developed by a consortium including Pratt & Whitney, competes with the CFM56, produced by GE Aerospace and Safran.
The V2500 is used in several aircraft, such as the McDonnell Douglas MD-90, Airbus A320 family, and Embraer C-390 Millennium. Pratt & Whitney claims it is the quietest and most fuel-efficient engine for the Airbus A320ceo family. The V2500-E5 variant provides 31,000 lbf of thrust for the Embraer C-390 Millennium.
The CFM56 has been delivered over 34,000 times, making it one of the best-selling jet engines. It powers aircraft like the Airbus A320ceo, Boeing 737 Classic and Next Generation models, Boeing KC-135R Stratotanker, and Douglas DC-8-70. The engine's thrust ranges from 18,500 lbf to 34,000 lbf.
