Spanning the marketSnecma develops, produces and markets engines and propulsion subassem-

blies for commercial airplanes. Working alone or in partnership, we apply the

propulsion technologies needed to cover all main market segments: commer-

cial airliners with more than 100 seats, regional and business aircraft. The

engines we produce are known for their performance, reliability, economical

operation and environmental friendliness.

Demanding market, encouraging outlookThe aviation market is a cyclical business. It is currently in a strong growth

phase, with major fleet replacement requirements. There are several reasons

for this trend: the steady growth of low cost carriers; increasingly stringent

operating standards; and a focus on economies of scale in maintenance. Soar-

ing oil prices are another decisive factor, driving greater demand for the lat-

est, most fuel-efficient engines.

Customers, whether aircraft manufacturers, airlines or leasing firms, are very

satisfied with the technological excellence of Snecmasproducts. However, they

are also increasingly demanding due to the unending market pressures, and in

particular they expect engines offering the lowest possible cost of ownership.

Air traffic on the riseAir traffic has been on a growth curve over the last 20 years. The Asian market

is enjoying buoyant economic growth these days, especially in China and India,with significant demand for new short and medium-haul aircraft. The regional

aviation market is also very dynamic, specially for 70 to 100-seat planes.

Snecma is therefore focusing its technological and commercial developments

to meet these two market trends.

InnovationOne of our main priorities is to maintain the technological excellence that

underpins our position as a major player in civil aviation. This depends on sus-

tained investments in research & technology, the development of partnerships,

and proactive technology intelligence.

Strategy and market


6/206 SNECMA COMMERCIAL AIRCRAFT ENGINES

CFM56 family

The worlds best selling engineFor over 30 years now, Snecma has developed, produced and marketed the CFM56

turbofan family through subsidiary CFM International, equally owned with General

Electric. The CFM56 is the most reliable engine of its generation. Different versions have

been developed to meet customer requirements in the thrust range from 18,500 to

34,000 pounds.

CFM56 engines hold nearly 50% of the engine market for all mainline jets (over

100seats).

Taking performance to a new planeFeaturing cutting-edge performance and reliability, CFM56 engines are recognized

worldwide for their exceptional time on wing and low operating costs. Another major fac-

tor in their market success is that they easily satisfy new environmental standards and

other regulatory requirements.

We have launched a number of research & technology programs to continue to improve

engine performance, in particular by reducing maintenance costs, noise and pollution.

CFM International:

complementary areasof expertiseWorking through CFM International,

our joint subsidiary with General

Electric, Snecma is responsible for

the following parts of the engine:

low-pressure section;

power transmission units;

several major subassemblies and

components (fuel control and

lubrication systems, electrical

wiring, etc.).

General Electric is responsible for the

following:

core (high-pressure section);

engine control system.

Striking the bestbalanceSnecma and General Electric split CFM56

assembly, testing and nacelle integration

tasks right down the middle. Responsi-

bility for individual engines depends on

which manufacturer is closer to the air-

craft manufacturer client, mainly

Airbus or Boeing. This approach, afundamental part of the Snecma/

General Electric partnership, mini-

mizes costs while maintaining

parity.

General Electric and Snecma have

built a textbook case of trans-

atlantic teamwork over the years,providing solid foundations to con-

tinue to develop the technologies and

engines that will power aircraft well into

the future.

CFM56-3 as sole-source power plant on

the third-generation Boeing 737, also

known as the 737 NG or Next Generation.

Developed in conjunction with the cus-

tomer, the CFM56-7B offers a number of

key advantages, including:

80% decrease in removal and

replacement time;

15% reduction in maintenance costs

over the CFM56-3.

These engines can be fitted with an

optional dual annular combustor (DAC),

which reduces nitrogen oxides (NOx) emis-

sions by nearly 40%.

CFM56 family

TECH56, bringing R&Tto marketCFM International launched the TECH56

research & technology program back in

1998 to anticipate and satisfy customer

requirements for improvements in per-

formance, operating costs and environ-

mental friendliness. Results have beenespecially satisfying, since they have

driven significant reductions in mainte-

nance costs, NOx emissions and fuel

consumption.

Some of the solutions developed through

the TECH56 program will be incorporated

on improved versions of the CFM56-7 and

CFM56-5B engines, powering the B737

and A320 families, respectively, and set toenter service in 2007 through the Tech

Insertion program. More specifically,

improvements concern the high-pressure

compressor (new blades), combustor

(enhanced dilution) and high and low-

pressure turbines (new blade airfoil,

improved durability).

Continuous

improvementContinuous improvement is a watchword at

CFM International. This is a longstanding

policy, since the dual annular combustor

now offered on CFM56 engines was already

being studied by Snecma and General

Electric 20 years ago. Furthermore, the

CFM56 features a modular design, making it

easy to incorporate new technologies.

LEAP56TM:Very ambitious goalsOur new research & technology program

LEAP56 (Leading Edge Aviation Propul-

sion) took over for TECH56 in 2005, and is

designed to provide the solid technical

foundations for CFM Internationalsprod-

ucts over the next thirty years.


Some of the technologies understudy include:

Light structures for most components

State-of-the-art technologies on fans, transmissions andcontrol systems

Innovative 3D design technologies (compressor andturbine)

Incorporation of more electric technologies

Optimized accessories

Quantum leap

in technologyThe next generation of engines will have to

offer higher performance than those now

in service. Designs will have to strike a deli-

cate balance, by reducing fuel consumption

(given unstable, but generally skyrocketing

oil prices), while still remaining simple

enough to contain maintenance costs.

However, perhaps the biggest challenge

will be to meet increasingly stringent envi-

ronmental regulations, by significantly

reducing noise and emissions.

Meeting these requirements will require a

quantum leap in technology spanning all

products. Snecma is already gearing up to

give aircraft-makers the right engines,

through new research & technology pro-

grams such as LEAP56, coordinated byCFM International.

Industrial turbines:derivative powerplantfor a growth marketThe LM6000 is an industrial turbine derived

from the CF6 aero-engine designed and

produced by GE. They are mainly used byindustry and municipalities to generate

electricity. General Electric has built up a

solid position in the market for 40 to

50 MW turbines, and Snecma naturally

participates through its partnership

on the CF6. Two LM6000 models are

offered, one conventional and the

other a Dry Low Emissions (DLE) version.

Snecma is a partner in several large turbofan engine

programs, taking responsibility for modules andsubassemblies within our scope of technical expertise.

Regional and business aviation

Purpose-designed engines for regional aviationThe regional aviation market is booming, especially in North America, Europe and Asia, and is expected to post the highest growth

rate in the air transport industry over the next 20 years. This market demands aircraft and engines that are purpose-designed to meet

specific thrust, cost of ownership and environmental requirements. Snecma is developing an engine tailored for this purpose, the

SaM146. The SaM146 is rated at 14,000 to 17,500 lb of thrust, and is intended for regional jets with 60 to 100 seats on the SM-X

demonstrator, a core design for a new family of engines targeting the long-range business jet market.


Market-oriented

innovationThe SaM146 features advanced technolo-

gies for economical operation. It capital-

izes on Snecmas extensive experience

with the market-leading CFM56, both

technologically and in terms of services. At

the same time, it takes advantage of our

experience with the core hot section on

the M88 fighter engine.

The first aircraft-maker to chose the

SaM146 is Sukhoi Civil Aircraft Company

of Russia, for their new regional jets.

SaM146and regional aviationDevelopment of the SaM146 kicked off in

2003.

Because of a particularly favorable out-

look in the Russian market, we teamed up

with Russian counterpart NPO Saturn to

develop this engine on an equal basis.

PowerJet, a single customercontact

To facilitate the developmentof the SaM146, Snecma and

NPO Saturn created the jointventure PowerJet in 2004.

PowerJet is in chargeof overall programmanagement, includingdesign, production,marketing and support.It is the single point ofcontract for the aircraftmanufacturer, deliveringa complete propulsion

system comprising theengine and nacelle a first

in the regional aviationmarket. PowerJet is also the single pointof contact for airline support services.In 2005 Snecma and NPO Saturn alsocreated VolgAero, a joint subsidiary thatwill produce components for the SaM146.


17/20


New engine conceptSnecma is also working on the core design

for a new family of engines targeting the

long-range business jet market. It could

eventually be used in 40 to 60-seat

regional jets as well. Rated at 8,500 to

10,500 lb of thrust, it incorporates the

latest advances from our commercial and

military engine research & technology

programs.

While it shares certain key technologies

with latest-generation engines such as the

SaM146 and CFM56, it will feature a

brand-new design. This will translate into

a significant 5 to 15% reduction in fuel

consumption and maintenance costs

compared to current generation engines,

while meeting upcoming environmental

requirements.
