TURBO-ELECTRIC DISTRIBUTED PROPULSION BENEFITS ON TH E N3-X
VEHICLE
James Felder, Aerospace Engineer, NASA Glenn Research Center
• A summary of recent study results on a turbo-electric distributed propulsion (TeDP) vehicle concept
named N3-X
• The TeDP system used in N3-X employs multiple electric motor-driven propulsors that are
distributed on an aircraft. The power to drive these electric propulsors is generated by wing-tip
mounted gas-turbine-driven electric generators on the HWB airframe
• N3-X would be able to reduce energy consumption by 70–72% compared to a reference vehicle, a
Boeing 777-200LR, flying the same mission. Predictions for landing and takeoff NOx are estimated
to be 85% less than the Tier 6-CAEP/6 standard. Two variants of the N3-X vehicle were examined
for certification noise and found to have ICAO Chapter 4 cumulative margins of 32EPNdB and
64EPNdB
• It is expected that the TeDP system may provide unprecedented reductions in fuel/energy
consumption, community noise, and landing and takeoff NOx emissions required in future transport
aircraft

KEYNOTE SPEAKER
James Free, Director, NASA Glenn Research Center
• The legacy of the National Advisory Committee for Aeronautics (NACA) lives on at NASA.
Commemorating 100 years since the founding of the NACA, NASA is shaping the next 100 years of
US aviation
• Air transportation is critical to US and global economic vitality. However, energy and climate issues
challenge aviation’s ability to be sustainable in the long term. Aviation must dramatically reduce
fuel use and related emissions. Energy costs to US airlines nearly tripled between 1995 and 2011,
and continue to be the highest percentage of operating costs
• NASA’s aeronautics research strategic vision is driven by this challenge and significant global
trends such as unprecedented economic growth of the Asia-Pacific region, rapid growth of urban
areas, and revolutionary technology development
• NASA has identified environmental responsibility as one the “mega drivers” that will be changing
the face of aviation over the next 20 to 40 years. NASA research centers and specifically NASA
Glenn have efforts for advancing technologies for big leaps in efficiency, environmental performance
and technologies for pioneering low-carbon propulsion

Michael Armstrong, Aerospace Systems Engineering Specialist, Rolls-Royce North
American Technologies
• Aircraft safety and reliability requirements govern the implementation of a superconducting turboelectric
distributed propulsion (TeDP) system’s redundancy and protection strategies
• These requirements drive impact concept feasibility through the overall effect on system mass and
efficiency
• Methods for determining optimal voltage, nominal operating voltage, power regulation, defining
system protection, and recovery requirements were established considering NASA’s N3-X aircraft
concept

to determine the optimal nominal operating voltage and to perform isolation and protection trade
studies

POTENTIAL PROPULSION SOLUTIONS FOR HYBRID-ELECTRIC AIRCRAFT
Paul Miller, Electrical Systems Specialist – Strategic Research, Rolls-Royce
• Hybrid propulsion has the potential to deliver reduced fuel burn through increased propulsive
efficiency resulting from higher bypass ratios and lower drag aircraft designs
• To realise the benefits of hybrid propulsion, high efficiency energy transmission from the remote
power generators to the propulsion fans is required. Superconducting electrical systems may have
this potential
• High temperature superconducting conductors and control devices show the potential to greatly
increase the transmission efficiency to the required levels when including the cryo-cooling subsystem
• Fully superconducting (both rotor and stator) electrical machines are being researched to maximise
the mechanical/electrical/mechanical conversion efficiency
16:35
ADVANCED TECHNOLOGY CONSIDERATIONS FOR FUTURE AVIATION
Giorgio Abrate, Engineering General Manager, Avio Aero
• Aviation technology advancements in material technologies, cooling methods, aero-mechanical
design capabilities, advanced manufacturing and more are enabling unprecedented performance
• However, continued pressure through higher fuel costs, increased energy demands, noise and
emissions may drive a new approach
• Alternative and integrated architectures such as distributed propulsion, hybrid-electric and
compound cycles may be among the many approaches needed to address the increasing demands
on aviation
• GE Aviation is shaping the future of flight and taking on these challenges by driving today’s
gas turbines to new performance levels and by developing revolutionary propulsion and system
architectures to meet the demands for the future of aviation
