Snecma, world-class
manufacturer of aircraft
and rocket engines
Snecma is the aerospace propulsion specialist in the
international technology group SAFRAN. We design,
develop and produce commercial and military aircraft
engines, as well as propulsion systems for launchers
and satellites. Our products are exported worldwide.

             Military engines
             Powering 20 types of aircraft in 40 countries

              Snecma designs, develops, produces and supports engines for
military transport, training and combat aircraft. Our flagship products are
the M53-P2 powering the Mirage 2000, the M88-2 on the Rafale, and the
TP400-D6 turboprop for the new Airbus Military A400M military transport.

             Commercial engines
             The broadest thrust range on the market

             Working with General Electric of the United States, Snecma
designs, produces, markets and supports the CFM56, the world’s best selling
commercial aircraft engine, and has a stake in the large turbofans CF6-80,
GE90 and GP7200. We are also developing the SaM146 for regional jets, and
preparing a new engine concept for the high-end business aircraft market.

             Space engines
             The best balance of performance, reliability and cost
              Snecma makes propulsion systems for both launch vehicles
and satellites, including the Vulcain®2 and HM7B engines for Ariane 5.
Our PPS®1350 plasma thruster recently set the world endurance record
for electric propulsion.

Strategy and markets

  Military aviation market
The military aviation market includes combat, training, tactical support and
transport aircraft. Snecma operates in three of these segments, primarily
addressing the governments who order the aircraft and the armed forces who
deploy them.

  Operating costs, a decisive advantage
Drawing on our technological expertise, we design products combining top
reliability and performance. The other major focus is reduced operating costs,
achieved by extending component life and streamlining maintenance opera-
tions. Through a sustained effort in research, technology and development,
we offer products that continue to drive down costs.

  Teaming up for the future
Because of the technological challenges, cost and long development cycles
characteristic of military engines, manufacturers are increasingly teaming up
to tackle these programs. Snecma is one of the pioneers in cross-border engine
programs. Today, we are part of Europrop International, a consortium in
charge of the development and production of the TP400-D6 turboprop,
powerplant of Europe’s new A400M airlifter being built by Airbus Military.

Snecma is a pioneer
engine programs.

Combat aircraft

The M88-2
was designed
for the Rafale
fighter, and
is especially
suited to
demanding low-
altitude penetration
and high-altitude
interception missions.

partnerships with research organizations, universities
and other companies in France, Europe and around
the world. The technologies developed through
these programs will offer the best tradeoff between
engine performance and cost.

R&T priorities
• Hot section: combustor and high-pressure turbine

• Control systems, especially electronic control units

• Compressor stability, and handling under extreme conditions

• Exhausts

• Afterburner

• Composite materials

Extending current programs
We are exploring a number of areas of research, but some of our current devel-
opments are already springboards for future technology leaps. For example,
some of the components being studied for the TP400-D6 could be used in
tomorrow’s manned and unmanned military aircraft, or even helicopters.

Top priorities:
customers and the future

Customer service
The top priority at Snecma is to give our customers top-flight service. We listen
to our customers, make sure they are satisfied by combining local support with
global reach, and anticipate their requirements.

Customers increasingly demand training. Snecma’s experts can be sent on-site
to teach operators the best way of using our hardware. In addition, we provide
a broad range of e-learning tutorials to give users the requisite background.

Technical assistance on site
Close customer support is essential. On request, Snecma sends technical assistance
teams to help operators. These teams, on short or long-term assignment, provide
assistance in maintenance, setting up workshops, qualification procedures, etc.

Maintenance or logistics
At Snecma, we can take charge of maintenance packages (procurement, man-
agement of parts and equipment availability), or of our customers’ logistics
needs, from forecasting requirements to delivery.

Hot line and warranties
Snecma has of course set up a hot line to quickly answer our customers’
questions and warranty inquiries.
