  1. SPACE EXPLORATION AND INTERNATIONAL COOPERATION Workshop – Washington D.C. June 21-22, 2004 ESA

  2. SNECMA, THE AEROSPACE PROPULSION AND EQUIPMENT GROUP 6,431 Millions of euros in 2003 Workforce : 39,695 (3237 in North America) 62% Propulsion 38% Equipment 77% Commercial 23% Military 55% Europe 27% USA

  3. VINCI VULCAIN 2 M51 RL10 B2 SNECMA SPACE AND MISSILE ACTIVITIES • Liquid & Solid Propulsion for launchers • Propulsion & Equipment for satellites • Solid Propulsion for ballistic & tactical missiles • Thermostructural composite materials MPS ARIANE PPS 1350

  4. SNECMA POWERS SMART 1 PROBE TO THE MOON The PPS 1350 Hall effect thruster built by Snecma Moteurs started to power SMART 1 to the Moon on September 30, 2003. Currently it has accumulated 2400 hours or firing and will reach the Moon orbit in September 2004 (after3500h of firing) After the first ignition, the thruster has been fired almost continuously to raise the orbit perigee. Then, the apogee is gradually increased until the spacecraft is captured by the Moon’s gravity From Earth to the Moon: 380 000 km with solar energy and 82 kg of Xenon

  5. A long time partnership with General Electric in aircraft engines CFM56 Snecma Moteurs: makes 23.5% of GE90 23.7% of GE90-115B Snecma Moteurs: makes 10% of CF6-80C 20% of CF6-80E GE90 & GE90-115B CFM56 CF6 50-50 JV Snecma Moteurs/GEAE

  6. Snecma Moteurs Meggitt Gimbal, Thermal protection Gas generator, Valve generator Flexible hose Purge valve Avio Support OxygenTP Snecma Moteurs Oxygen turbine HydrogenTP Hydorgen turbine Hot gas valve EADS APP Starter, igniters Chamber Snecma Moteurs Oxygen supply line, Hydrogen supply line Sensors Vulcain 2 Electrovalve unit Nozzle Snecma Moteurs Sensors Sensors Sensors Chamber valve Snecma Moteurs is leading a European cooperation for the Ariane cryogenic Engines

  7. SM146 - A new cooperation with Russia 50-50 JV & SM146 Powering Sukhoi RRJ

  8. C/C Nozzle for RL10-B2 Pratt & Whitney Engine • Lightweight Carbon/Carbon deployable • nozzle • Design by SPS in close cooperation • with P & W - Production by SPS • Snecma Propulsion Solide : • CompositeTechnologies & Facilities in • Bordeaux (France)

  9. THE CASE OF SPW 2000 COOPERATION FAILURE • Attempt in 1999/2000 to join Vinci and RL-60 engines into one program aimed • at developing a single engine for upper stages in the US (Atlas & Delta) and in • Europe (Ariane) • Development cost shared between P&W and ESA • Global Development & Production costs expected to be lower because of sharing • facilities, expertise, technologies,…and having higher production rate (larger • market) • P&W in the US and Snecma in Europe leading the usual partners in ESA countries • License obtained quickly from US government with some provisos related to • export control

  10. THE CASE OF SPW 2000 COOPERATION FAILURE Lessons learned • Geographic return rules of ESA are difficult to conciliate with transatlantic • cooperation • The Vinci program was already started by ESA (with European participating • countries contributions and returns) when the SPW2000 was initiated • European concerns over US Government policies (provisos) that could have led to • future export licence restrictions for Ariane

  11. MAIN FEATURES OF EUROPEAN SPACE COOPERATION • COOPERATION WITHIN EUROPE IS SPECIFIC : • EUROPEAN STRATEGY OF INDEPENDANT ACCESS TO SPACE • BUILT OVER DECADES FOR ARIANE PROGRAMS • HAS INVOLVED MORE AND MORE COUNTRIES / COMPANIES FROM THE • BEGINNING • GEOGRAPHICAL RETURN RULES • HAS CONSTRUCTED OVER THE YEARS SOME “SPECIALTIES” DISTRIBUTION OF • TECHNICAL & INDUSTRIAL BASIS IN EUROPE WITH IMPORTANT INVESTMENTS

  12. CONCLUDING REMARKS (1) • SOME ” SUCCESS “ FACTORS : • POLITICAL SUPPORT • STRONG ORGANIZATION FOR MANAGEMENT : • STRONG AND CLEAR RESPONSABILITY/MANAGEMENT AT SYSTEM LEVEL • CLEAR REQUIREMENTS /SPECIFICATIONS WITH INVOLVEMENT OF INDUSTRY • “REASONABLE” TECHNICAL CHOICES BASED ON PREPARATORY PHASES • STANDARDIZED MANAGEMENT PROCEDURES, INCLUDING QUALITY • COST CONTROL AND DESIGN-TO-COST APPROACH • REALISTIC BUDGET REQUIREMENT • NEED TO INVOLVE INDUSTRY NOT ONLY IN DEMONSTRATION AND DEVELOPMENT • BUT ALSO IN PRODUCTION (RETURN ON INVESTMENT)

  13. CONCLUDING REMARKS (2) • SNECMA HAS A NUMBER OF PRODUCTS AND TECHNOLOGIES THAT COULD SERVE SPACE EXPLORATION: • SOLID AND LIQUID ENGINES • ELECTRIC PROPULSION • ADVANCED HOT STRUCTURES • SPACE EQUIPMENT • IN THE FRAME OF DIFFERENT TYPES OF COOPERATION…

  14. VINCI : A HIGH PERFORMANCE, FLEXIBLE, MULTI-PURPOSE ENGINE • LAUNCHERS UPPER STAGES : ARIANE, DELTA, ATLAS,… • SPACE VEHICLES FOR MOON & MARS MISSIONS, SPACE TUGS,… • DERIVATIVES WITH OTHER PROPELLANTS (LOX/METHANE,…)
