3 OR ARCHITECTURES AND A/C INTEGRATION 3/ Forum AE July 1 st, 2014 Snecma R&T Direction

4 MAIN TECHNICAL OBJECTIVES: ACARE / Forum AE July 1st, 2014 Snecma R&T Direction

5 CURRENT TECHNOLOGY DEVELOPMENTS : SAGE2 (SNECMA LEAD) Aircraft Aircraft Green Rotorcraft Sustainable and Green Engines IN THE FRAME OF «CLEAN SKY» EUROPEAN PROGRAM SAGE ITD : SAGE1 TO 6 Technology Evaluator SAGE2 : OPEN ROTOR DEMONSTRATOR Concept Aircraft LEADER : SNECMA GROUND TEST : DEC 2015 Eco- Design Smart Fixed Wing Green Regional G Systems for Green Operations Eco- Design TECHNOLOGIES & DEMONSTRATORS 5/

6 SAGE2 : AN INTEGRATED POWERPLANT SYSTEM 6/ Forum AE July 1st, Snecma --R&T Direction

7 SAGE2 : DEMO CONFIGURATION GKN 7/

8 NEW TECHNOLOGIES FOR OPEN ROTOR (1/4) OPEN ROTOR ARCHITECTURES NEED A HIGHER DEGREE OF INTEGRATION OF THE PROPULSION SYSTEM AND THE AIRCRAFT THAN CONVENTIONNAL TURBOFANS >AERODYNAMICS >ACOUSTICS >MECHANICS DEVELOPMENT & USE OF MORE AND MORE PREDICTIVE SIMULATION TOOLS ASSOCIATED WITH MORE AND MORE POWERFUL COMPUTERS 8/ Onera URANS calculation acoustic directive emissions

9 NEW TECHNOLOGIES FOR OPEN ROTOR (2/4) TEST CAMPAIGNS IN WIND TUNNELS ON PROPULSION SYSTEMS : FIRST ALONE, THEN IN INSTALLED CONFIGURATIONS (WINGS, AIRCRAFT), SEE HEREUNDER AEROACOUSTIC TEST PERFORMED IN ONERA MODANE-FRANCE 9/

10 NEW TECHNOLOGIES FOR OPEN ROTOR (3/4) DEVELOPMENT OF NEW COMPONENTS LINKED TO THE OPEN ROTOR ARCHITECTURE : HIGH POWER COUNTER-ROTATING GEARBOX ROTATING FRAMES GREEN BARRELS ENGINE INLET PREVENTING FROM F.O.D. ROTATING NACELLES AND PLUG VARIOUS TYPES OF BEARINGS : LARGE DIAMETER HIGH LOAD FOR ENGINE BLADE ROTORS RESTRICTED VOLUME ALTERNATE LOAD FOR BLADES HUBS DEVELOPMENT OF NEW INTERFACE BETWEEN AIRCRAFT PYLON AND PROPULSION SYSTEM MOUNTING SYSTEM DESIGNED FOR OPEN ROTOR PUSHER CONFIGURATION 10 /

11 NEW TECHNOLOGIES FOR OPEN ROTOR (4/4) DEVELOPMENT OF A SPECIFIC CONTROL SYSTEM FOR GEARED OPEN ROTOR : TWO MORE PARAMETERS TO CONTROL, SPEEDS OF FWD AND AFT PROPELLER ROTORS IMPLEMENTATION OF FUNCTIONS AT THE PROPULSION SYSTEM LEVEL THAT LEAD TO DEDICATED TECHNOLOGIES OR DESIGNS, FOR EXAMPLE: THERMAL MANAGEMENT OF THE NACELLES DE-ICING OF THE PROPELLER BLADES DEVELOPMENT & USE OF NEW LOW-WEIGHT MATERIALS : COUNTER-ROTATING COMPOSITE BLADES, ORGANIC MATRIX RTM INJECTED TIAL BLADES FOR HIGH SPEED POWER TURBINE DEVELOPMENT & USE OF ADVANCED HEALTH MONITORING AT ENGINE AND AIRCRAFT LEVEL 11 /
