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 • 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 2015-16 (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 Tunnelverification of inlet & bypass efficiency (scheduled in 2014) Clean Sky / GRC– IPAS 2013
Towards a more electrical AircraftSample Future System • Good results to date • Energy Recovery • 1st demo by end 2012 • Electrical Main Rotor Actuators • CDR scheduled in July 13 • Starter/ generator • PDR passed • Power Converter & Storage • Detailed Requirements Clean Sky / GRC– IPAS 2013
High Compression Engine on Light Helicopter • 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 (@MGB inlet): 330kW up to 2500m and ISA+20°C • Achievement on track (39 months in total from design to integration) March 2013- first engine test Early 2014 - first ground tests Clean Sky / GRC– IPAS 2013
Environment-Friendly Flight Paths SNIapproach (@TLS airport/OPTIMAL project) • 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 Clean Sky / GRC– IPAS 2013
Towards promising results • Innovative Rotor blades: • Active Twist Blade: blade segment tested • Active Gurney Flap: rotor tested (whirl tower, flight) • 3D-Optimized Blade: rotor tested (whirl tower) Q2/2015 • High Compression Engine Demo • Power pack: all bench tests passed • Iron Bird & helo ground tests passed; ready for flight testing Q2/2014 • Environment-Friendly Flight Paths • IFR & VFR procedures & systems: validated in operational environment • Underpinning & complementing SESAR (rotorcraft) Q2/2015 Q4/2015 • Drag reduction and shape optimisation • Individual devices/mods: WT test (TRL4) or flight (TRL6) • Integration with interactions: WT test with complete model • (common platform GOAHEAD) Q3/2015 • Technos for More Electrical Rotorcraft • Subsystems & Equipment: Individual bench tests • Integrated system: Copper Bird testing (TRL5) • Electrical Tail Rotor (TRL 5) • Electric taxiing (TRL5) Q3/2015 Clean Sky / GRC– IPAS 2013
