CFM is pushing the limits with the new LEAP engine to meet the performance and reliability expectations made to its customers. All in all, CFM will have a total of 60 engines builds to execute the most extensive ground and flight test certification program in the company’s history. These engines will accumulate approximately 40,000 cycles of testing before entry into service, the equivalent of 15 years of airline service.

Like all new engines, the LEAP family will complete challenging tests on its way to certification. Among them: Fan Blade Out: The engine must be able to contain a fan blade breaking off, without suffering critical damage. The test

requires a special fan blade with an small embedded explosive charge, to separate it on command during the test.

Bird ingestion test: To demonstrate that the engine maintains 75% of its thrust for 20 minutes following a bird ingestion.

Block test: Extreme endurance tests to check the operability of the engine, running it at triple redline (maximum fan speed; maximum core speed; and maximum exhaust gas temperature) over 5,000 simulated cycles.

Icing Tests: To demonstrate that the ingestion of a block of ice does not affect engine performance

INNOVATIVETECHNOLOGIES

Additive manufacturing

• 3-D Printing

Additive manufacturing is transforming the way engines are built. This technology "grows" engine parts directly from a CAD* file using layers of fine metal powder and a laser. This results in complex, fully dense and lighter parts, manufactured in a fraction of the time it would take using traditional subtractive methods. Each LEAP engine will contain up to 19 metal 3-D-printed fuel nozzles, which is up to 25% lighter than its counterparts. CFM will produce approximately 100,000 of these parts each year…

• 3-D Woven carbon fiber composites: less weight, more durable

Advanced materialsThe 3-D woven RTM (Resin Transfer Molding) carbon fiber composites used for the fan blades and casing on the LEAP engine are revolutionizing the single-aisle market. This new technology reduces the weight (500 lbs per engine) of the fan module. It also enables blade geometries that are challenging to produce with titanium. The 3-D RTM technology is highly impact resistant and thus reduces maintenance requirements.* Computer Assisted Design.

CFM ‘s LEAP engine is an impressive package of innovative technologies. It is set to establish a new standard in engines for single-aisle commercial jets, based on its 15% reduction in fuel consumption and CO2 emissions versus current engines.

CFM has a tradition of consistently investing in technologies that enhance product performance and customer satisfaction.

The best-selling CFM56 family successively introduced a full array of product upgrades, including the FADEC (Full Authority Digital Engine Control), several generations of 3-D aerodynamic design and, most recently, the suite of improvements dubbed Tech Insertion in 2007 and the CFM56-7BE and CFM56-5B PIP (Performance Improvement Package) introduced in 2011.

All of these enhancements were not only incorporated in new engines, but also available as upgrades on engines already in service. Over the years, CFM has improved specific fuel consumption*, all while reducing emissions and significantly lowering maintenance costs.

This long-standing philosophy of continuous improvement is already an integral part of the LEAP family, and will be pursued throughout its service life. CFM has also introduced lighter and stronger materials. The company’s experience with composites reaches back more than 30 years, unrivaled among aero-engine manufacturers.

Research is ongoing and the product line will eventually add an increasing number of thermo-structural composite parts to reap the benefits of both the lighter weight and higher temperature capabilities these materials provide.

* by more than 5% and increased thrust by 16%.

TECHNOLOGY MATURATION

CFM has always met its commitments by delivering reliability for all customers.

To date, the company has developed different engines models for 21 aircraft entry into service, all of which were delivered on time, as well as eight upgrades, certified on time and on spec.Today, this textbook case of French-American industrial partnership can be summarized in three figures: nearly 28,000 engines delivered on time, more than 750 million flight-hours, and a fleet-wide 99.98% dispatch reliability rate.

CFM has leveraged all of this unrivaled experience for the LEAP engine program, and the basic principle hasn’t changed: give customers the best possible engine, today and for years to come.

CFM has a long history of constantly investing in its product lines to deliver greater value.

This is the approach the company is using to develop the LEAP engine and will continue to develop new technologies that will be incorporated into the engine throughout its service life, as well as in a new generation of engines.

LOWEST EXECUTION RISK

Industrial facilities smooth running, constantly improving.

CFM has designed, tested, certified, produced and supported the largest fleet of commercial jet engines in the single-aisle market over the last 30+ years. This achievement is anchored in the development and continuous improvement of world-class facilities on both sides of the Atlantic, with each partner responsible for half the workload.

GE is in charge of the core, comprising the high-pressure compressor and turbine and the combustor. Snecma designs and builds the low-pressure section, including the fan, the low-pressure compressor and turbine, and the accessory gearbox. Final assembly of CFM engines is performed by GE in Evendale, Ohio, near Cincinnati and by Snecma at its facilities in Villaroche, France near Paris.

CFM maintains the highest production rate in the industry and the company is modernizing and expanding its facilities to ensure the ramp-up in production for the new LEAP engine. Both GE and Snecma have added new manufacturing capability at sites throughout the U.S. and France, making a combined capital investment of nearly $800 million U.S.

The company is ramping up CFM56 production to more than 1,600 engines in 2016 before it begins to transition to LEAP engine production.

The full transition is expected to be completed by about 2020 with an anticipated production rate of more than 1,800 engines per year. CFM will continue to build CFM56 spare engines for several years.
