    • Future Green Rotorcraft Light Helicopter Powered with a Diesel Engine© 2011 – all rights reserved Yves Favennec (Eurocopter) 1 1 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Rationale for Diesel engines on helicopters (1) What is stakes? Aviation impacted by global CO2 => ACARE target: -50% emission problem Operators’ business threatened by => fuel consumption per FH soaring fuel cost© 2011 – all rights reserved Helicopter configuration less energy-efficient Inherent to hovering capability than fixed-wing A/C 2 2 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Rationale for Diesel engines on helicopters (2) What about engine fuel efficiency?  Incremental fuel-efficiency improvements for small turbo-shaft engines  Major improvement opportunity offered by Diesel technology: Specific Fuel Consuption (g/kW/hr) POTENTIAL: typical turboshaft SFC More than 30% 1000 fuel/CO2 economy typical modern Diesel engine on a typical H/C Huge gain in mission profile© 2011 – all rights reserved cruise, descent Sizable gain at Take-Off 0 0% Output Shaft Power (fraction of MTOP) 100% Even higher benefits in hot/high conditions 3 3 Engine size effect Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Demonstration Project Members Clean Sky Member / Topic Manager HIPE AE440 Consortium (Clean Sky Partners) Participant Project Coordinator© 2011 – all rights reserved Third Party Third Party Sub-Contractor Third Party 4 4 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Demonstration Objectives Specify, test & validate a Diesel engine prototype responding to helicopter requirements Existing General Aviation engines: too small and/or too heavy  Identify & resolve major integration difficulties Requires exploration of full flight envelope (maturity TRL 6) Substantiate achievement of fuel &© 2011 – all rights reserved emission reduction targets The demonstrator H/C will be a prototype of the small single-engine EC120 which can most conveniently be modified for that purpose. 5 5 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Technical Challenges – Power Pack (1)  Weight of Power Pack incl. cooling system & ancillary equipments  Engine core strength & reliability  Fuel consumption & gas emission using standard Jet A1 fuel© 2011 – all rights reserved 6  Engine control compatible with helicopter control 6 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Technical Challenges - H/C integration (2)  Start, clutch operation in typical H/C flight domain  Engine noise exterior noise & cabin  Torque oscillation alleviation  Engine vibration© 2011 – all rights reserved 7 7 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Technical Challenges - H/C integration (3)  Pilot interface, pilotability, handling  Cooling system qualities efficiency esp. in hover  Aerodynamic drag© 2011 – all rights reserved 8 8 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Demonstration Plan 2008 2009 2010 2011 2012 2013 2014 2015 Preliminary studies, specifs Partnership Completed Engine Design Design of H/C proto mods CDR PDR Engine manufacturing Engine integration & bench tests© 2011 – all rights reserved FAI H/C mods manufacturing H/C integration & testing Ground Flight 9 9 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Demonstration Plan - Expected results (1) Engine Power Pack CO2 & fuel SFC <230 g/kW/h Weight Reliability (potential) < 0.8 kg/kW TBO>2000 hr© 2011 – all rights reserved Design to Cost 10 RC < turboshaft 10 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Demonstration - Expected results (2) Helicopter demonstrator integration (CS & beyond) Environmental impact -30% CO2 per operation© 2011 – all rights reserved Full flight Payload-Range envelope assessed explored 11 11 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
    • Perspectives Strong market expectation for fuel efficient helicopters (EU & global)  Advanced Diesel technology mature in automotive sector  Adaptation to General Aviation in progress  Still significant technical challenges ahead for adaptation to vertical flight  Broader market for very high performance Diesel engine: General Aviation, UAVs, APUs.© 2011 – all rights reserved Helicopter industry & engine manufacturers agree to :  Conduct a complete demonstration by 2014 ;  Further develop & integrate Diesel techno on future light H/C 12 products. 12 Clean Sky –Round table “Future Green Rotorcraft », IPAS 23 Jun 2011
