High Compression Engine on Light Helicopter

Clean Sky / GRC– IPAS 2013

An objective-driven approach implemented through demonstrators

Innovative Rotor Blades

-3D-Optimized BladeBlade 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 rotorActive 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 2013

-Rotor hub & pylonOptimisation 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 reductionStudy of different active and passive devices Synthetic 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)

High Compression Engine on Light Helicopter

Clean Sky / GRC– IPAS 2013

-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

Environment-Friendly Flight Paths

Clean Sky / GRC– IPAS 2013

-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(@TLS airport/OPTIMAL project)

High Compression Engine Demo- Power pack: all bench tests passed- Iron Bird & helo ground tests passed; ready for flight testing

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