Major Technical Challenges
Leader
Weight, weight, and weight…
Even more crucial than for helicopters, why?
Addital components: wing, props , gear boxes, shafts
Stronger airframe for high speed: dynamic pressure, bird impact
Fully stowable landing gear
High power engines and transmission chain
Aerodynamic efficiency:
Eurocopter ETFM/ FT/ 10/12/212
Take-Off Weight capability
Lift-to-Drag ratio in cruise
Anti-torque function and yaw control in hover
Control & optimisation of: Attitude, RPM, Lift/Thrust split
across flight envelope

Subsystem: Fuselage & Cabin
Leader
Scope
Partly based on existing H/C structural elements (as possible)
Eurocopter ETFM/ FT/ 10/12/212
Many parts fully re-designed or deeply modified:
Rear part to fit junction with specific tail
Canopy, doors & windows
Main frames, mechanical deck, upper cowlings
Landing gear
Specific Requirements & Challenges
Non pressurized cabin, large access doors as needed for typical rescue tasks
Strong structure for high dynamic pressure and impact resistance: bird strike
Fully stowable landing gear: specific architecture, electrical actuation (possible option)
Aerodynamic cleanliness: shape, excrescence elimination, smooth joints, etc
Weight optimised (!)

Organisation
40% of overall work to be performed by Leader; 60% allocated thru open competition (Core Partners,
Partners)
Tight schedule to fly demonstrator in 2018
Core partners expected to commit & deliver timely for overall programme completion
components/systems compliant with aero prototyping standards, with docs needed for Permit-to-Fly
Extensive use of state-of-art simulation tools in a concurrent engineering approach e.g. “numerical wind
tunnel”
Successful Demo will pave the way to sustainable leadership & growth in13EU
