CFM International’s LEAP family continues to be the engines of choice for next-generation single-aisle aircraft. The order for 50 LEAP-1C-powered C919 aircraft announced by COMAC at the Zhuhai Air Show pushed total LEAP engine orders and commitments to 4,352 engines at a list price value of more than $52 billion U.S.
CFM’s LEAP-1C is the sole Western powerplant for the new 150-passenger C919 scheduled to enter commercial service in 2016. Following COMAC’s announcement, there are now 760 LEAP-1C engines on order to power 380 C919 aircraft.
The LEAP-1B is the sole powerplant for Boeing’s new 737 MAX aircraft schedule to enter service in 2017. To date, CFM has received firm orders for 1,876 LEAP-1B engines to power 938 737 MAX airplanes.
The LEAP-1A is one of the engine options for the Airbus A320neo family. To date, 1,192 LEAP-1A engines have been ordered to power 596 A320neo aircraft. This total represents 51 percent of the total A320neo orders for which an engine selection has been made.
The foundation of the LEAP engine is heavily rooted in advanced aerodynamics, environmental, and materials technology development programs. It will provide up to 15 percent better fuel consumption and an equivalent reduction in CO2 emissions compared to today’s best CFM engine, along with a 50 percent reduction in oxides of nitrogen emissions, and up to a 15 decibel reduction in noise. All this technology brings with it CFM’s legendary reliability and low maintenance costs.
