To date, the company has developed21 different engine models, all deliveredon time and on spec as well as 8 enginesupgrades, certied on time and on spec.

Today, this textbook case of French-American industrial partnershipcan be summarized in three gures:25,000 engines delivered on time, more than630 million ight-hours, and a eet-wide99.98% dispatch reliability rate.

CFM has leveraged all of this unrivaledexperience for the LEAP engine program,and the basic principle hasnt changed: givecustomers the best possible engine,today and for years to come.

CFM has a long history of constantlyinvesting in its product lines to delivergreater value.

This is the approach the company is usingto develop the LEAP engine and will continueto develop new technologies that will beincorporated into the engine throughoutits service life, as well as in a new generationof engines.

techolog rives perormaceThe overall performance of an aircraft

engine is the sum of an optimizedarchitecture and the technologies usedin all major components: the low- andhigh-pressure compressor and turbine,combustor, accessory equipment, digitalengine control unit, and even the nacelle.

Successfully integrating all of these factorsdemands extensive experience and aportfolio of world-class technologies.

Thenew LEAPengineembodies theexpertiseand technologies developed over the lastfour decades by GE and Snecma.

The LEAP engine combines breakthroughtechnologies with proven performance,drawing on CFMs experience as a worldleader in the narrow-body market.

For the new family of advanced LEAP

turbofans, CFM chose technologies thatbring high propulsive efciency, low fuelconsumption, and low maintenance costs,including a larger diameter, low-speed fanfor a higher bypass ratio and an advancedhigh-efciency core.

Advanced LEAP technologies include carbonbercomposites, ceramicmatrix composites,and other leading-edge materials, as well asfourth-generation 3-D aerodynamic designfeatures developed by world-class R&Dteams and proven through extensivetesting and hundreds of millions of hoursof operational experience.

The result is an outstanding powerplantready to deliver a host of benets to CFMcustomers.

COntInuOuS tEStInG FOR PROVEn

MAtuRItyCFM has always invested in technologiesthat enhance its products to make sure that

customers continue to improve their ownperformance. The best-selling CFM56 familysuccessively introduced full authority digitalengine control (FADEC), several generationsof 3-D aero design and, most recently, the suiteof improvements dubbed Tech Insertion in2007 and the CFM56-7BE and CFM56-5P PIP(Performance Improvement Package) in 2011.

All of these enhancements were not onlyincorporated in new engines, but also availableon engines already in service. Over the years,CFM has decreased specic fuel consumptionby more than 5% and increased thrust by 16%,while reducing emissions and signicantlydecreasing maintenance costs.

This long-standing philosophy of continuousimprovement, part of CFMs DNA, is already

an integral part of the LEAP family, and willbe pursued throughout its service life.

CFM has also introduced lighter and strongermaterials. The companys experience withcomposites reaches back some 30 years,unrivaled among aero-engine manufacturers.

Research is ongoing and the product linewill eventually add an increasing number ofthermo-structural composite parts to reap thebenets of both the lighter weight and highertemperature capabilities these materialsprovide.

Since its formal launch in 2008, the LEAPengine has been setting a new standardfor the single-aisle commercial jet market.Its leadership is anchored in innovative,

even revolutionary technologies, includingthe wide use of composite materials anda proven architecture that provides industryleading propulsive efciency.

In 2009, Chinese aircraft manufacturerCOMAC chose the LEAP-1C as the soleWestern powerplant for its new C919,opting for an integrated propulsionsystem (IPS) that includes the engine,nacelle and thrust reverser. At the endof 2010, Airbus chose the LEAP-1A to powerits new A320neo, followed in August 2011by Boeing, which selected the LEAP-1Bas the exclusive engine on its new 737 MAX.

Each version of this engine is being optimizedto meet the aircraft manufacturers specicrequirements, delivering maximum performancein terms of reliability, fuel consumption and

maintenance costs. CFM already has a veryhealthy backlog of orders for all threeLEAP-powered airplane applications.

The LEAP engine family will maintain CFMslong-standing leadership position in thesingle-aisle segment, for which there isa projected demand for more than40,000 engines over the next 20 years.
