LISI GROUP - 2016 Activity report

LISI 2016 ANNUAL REPORT

The LEAP engine, for which LISI AEROSPACE has

industrialized, and now manufactures series of

several complex structure components (leading

edges, compressor blades, OGV, air intake lips,

etc.), is developed by CFM International (Safran-

General Electric). In its production and fast ramp-up

phase, it is designed to equip new generation

single-aisle aircraft.

Ramp-up of the LEAP engine

LISI AEROSPACE has been engaged for several years in the

development of new generation engines. The LEAP program,

conducted by CFM International (Safran-GE), should help to

gradually replace the CFM56 (the best-selling engine in the

world). On its part, Pratt & Whitney is working on the GTF (Geared

Turbofan) version of the PW1000G engine. Essential to the success

of Boeing’s B737-Max and Airbus’s A320neo

(New Engine Option)

single-aisle aircraft, these new engines are the subject of specific

attention, both in terms of industrialization and performance. The

difficulties encountered by Pratt & Whitney on the GTF program,

however, have led Airbus and CFM to maintaining the rates for

the CFM56 at a high level and to delivering CEO (Current Engine

Option) instead of NEO versions. In contrast, the ramp-up phase

initiated in 2016 on the LEAP engine should continue this year:

the rates and quantities delivered should double by the second

half of 2017.
