Environmental Objectives Clean Sky / GRC– IPAS 2013

Innovative Blades Drag Reduction Eco-friendly Design More Electrical RotorcraftOptimised Flight Paths High Compression Engine on Light Helicopter Clean Sky / GRC– IPAS 2013 An objective-driven approach implemented through demonstrators

Innovative Rotor Blades -3D-Optimized Blade Blade design for improved performances (stall alleviation, increased lift and reduced drag) PDR passed, Detailed design of full scale rotor in progress TRL 5/6 to completion (ground test demonstration) -Active Gurney Flap rotor Active device (Gurney Flap) actuated once per revolution and blended into blades: lift increased and reduced power CDR passed Both model scale & full scale tests under preparation Ground tests/ Flight test in 2014 (TRL6) Clean Sky / GRC– IPAS 2013

Drag reduction Clean Sky / GRC– IPAS Rotor hub & pylon Optimisation of specific helicopter features (rotor hub, aft body, landing skids,) to reduce drag effects Wind Tunnel tests in progress (light& medium twin engine configs) Best solutions to be flight-tested in (TRL6) -Flow separation control devices for drag reduction Study of different active and passive devices Synthetic jets and steady blowing: successful Wind Tunnel Tests (TRL 4) -Engine installation Optimised engine installation (air-inlet, exhaust pipe)for both conventional and Tilt-rotor platforms ERICA tilt-rotor nacelle: Wind Tunnel verification of inlet & bypass efficiency (scheduled in 2014)

Towards a more electrical Aircraft Sample Future System Clean Sky / GRC– IPAS 2013 Good results to date -Energy Recovery 1 st demo by end Electrical Main Rotor Actuators CDR scheduled in July 13 -Starter/ generator PDR passed -Power Converter & Storage Detailed Requirements

High Compression Engine on Light Helicopter Clean Sky / GRC– IPAS Benefits of this Technology Lower fuel consumption (- 30% Specific Fuel Consumption) Reduction of emissions (-40% CO2, -50% NOx) Increased distances with the same amount of fuel (roughly double is possible in (roughly doubled in certain missions) Reduced Direct Operating Costs by up to 30% (DOC) Improved helicopter performance in hot & high conditions -Technical Data Common rail high pressure injection (1800bar) Turbocharger with air/air intercooler Functions with kerosene Core Engine Mass (dry): 197 kg/ Installed Powerpack: 249 kg Power output inlet): 330kW up to 2500m and ISA+20°C -Achievement on track (39 months in total from design to integration) March first engine test Early first ground tests

Environment-Friendly Flight Paths Clean Sky / GRC– IPAS Flight Procedures Designed with ATM specialists; data base acquired IFR and VFR procedures optimised for take-off and landing phase:  GPS-based approach  Simultaneous Non Interfering approach (SNI) -Flight Guidance systems Pilot guidance & autopilot designed -Verification of acoustic efficiency Successful flight testing completed in June 13 for IFR-LPV automatic approach SNI approach airport/OPTIMAL project)
