High Compression Engine on Light Helicopter

Clean Sky / GRC IPAS 2013

An objective-driven approach implemented through demonstratorsInnovative Rotor Blades3D-Optimized BladeBlade design for improved performances (stall alleviation, increased lift and reduced drag)PDR passed, Detailed design of full scale rotor in progressTRL 5/6 to completion (ground test demonstration)

Active Gurney Flap rotorActive device (Gurney Flap) actuated once per revolution and blended into blades: lift increased and reduced powerCDR passedBoth model scale & full scale tests under preparation Ground tests/ Flight test in 2014 (TRL6)

Clean Sky / GRC IPAS 2013Drag reduction

Clean Sky / GRC IPAS 2013

Rotor hub & pylonOptimisation of specific helicopter features (rotor hub, aft body, landing skids,) to reduce drag effectsWind 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 reductionStudy of different active and passive devicesSynthetic jets and steady blowing: successful Wind Tunnel Tests (TRL 4)

Engine installationOptimised 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)

Good results to dateEnergy Recovery 1st demo by end 2012Electrical Main Rotor Actuators CDR scheduled in July 13Starter/ generator PDR passedPower Converter & StorageDetailed Requirements

High Compression Engine on Light Helicopter Clean Sky / GRC IPAS 2013Benefits of this TechnologyLower 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 DataCommon rail high pressure injection (1800bar)Turbocharger with air/air intercoolerFunctions with keroseneCore Engine Mass (dry): 197 kg/ Installed Powerpack: 249 kgPower output (@MGB inlet): 330kW up to 2500m and ISA+20C

Achievement on track (39 months in total from design to integration)March 2013- first engine test Early 2014 - first ground tests

Environment-Friendly Flight Paths

Clean Sky / GRC IPAS 2013Flight ProceduresDesigned with ATM specialists; data base acquiredIFR and VFR procedures optimised for take-off and landing phase: GPS-based approachSimultaneous Non Interfering approach (SNI)

Flight Guidance systemsPilot guidance & autopilot designed

Verification of acoustic efficiency Successful flight testing completed in June 13for IFR-LPV automatic approach

SNI approach(@TLS airport/OPTIMAL project)

High Compression Engine DemoPower pack: all bench tests passedIron Bird & helo ground tests passed; ready for flight testing

Innovative Rotor blades:Active Twist Blade: blade segment testedActive Gurney Flap: rotor tested (whirl tower, flight) 3D-Optimized Blade: rotor tested (whirl tower)
