Transcript of IATA 32 Technology

Technology
Roadmap to emissions reduction
CLIMATE CHANGE
Aviation’s contribution to climate change
STRONG TRACK RECORD
IMPACT ON 2050 EMISSIONS
AIRCRAFT NOISE REDUCTION
ENVIRONMENT TECHNOLOGY AREAS
Fuel savings and carbon emissions
Aviation represents
about 2% of global CO emissions
about 3% of global climate change impact including non-CO effects
CO
Water vapour
contrails & cirrus
NOx, particles
Over the last 50 years
Our target:
TECHNOLOGY – FUEL SAVING POTENTIAL
Retrofits:
Wingtips
More efficient APU
Engine retrofits
Composite secondary structures
Design updates:
New engines (geared turbofan / counter-rotating fan)
Composite primary structures
Active load alleviation
New aircraft designs
(after 2020):
New engine architecture, incl. open rotor
Natural/hybrid laminar flow
New aircraft designs
(after 2030):
Variable cycle
Hybrid wing body
Strut-braced wing
Fuel cell
Battery-powered aircraft

AIRCRAFT TECHNOLOGY AREAS
Engines
RADICALLY NEW AIRCRAFT CONFIGURATIONS
Other than tube-and-wing, e.g.:
Blended wing body
+radical
configurations
Radically new configurations:
Slow market penetration due to fleet renewal cycles
Could play a larger role beyond 2050
LOCAL AIR QUALITY (LAQ)
Emissions regulated by ICAO standard:
Nitrogen oxides (NOx)
Hydrocarbons (HC)
Carbon monoxide (CO)
Particulate Matter (PM)
New – will replace current smoke standard
34000 new aircraft over next 20 years (20000 growth, 14000 replacement)
Local air quality
Environmental noise
Climate impact of aviation
“Evolutionary” technologies: aerodynamics, structure, propulsion
Climate action technology roadmap
“Radical” technologies: new aircraft configurations, new propulsion energies
Fuel burn: –70%
Noise: –75%
Soot: eliminated
Hydrocarbons: –90%
Recent aircraft types consuming less than 3 l/100 pax km
Well on track (x.x% in average between 2009 and 2015)
1.5% p.a. average improvement in fuel efficiency by 2020
New aircraft help
Investment $4.5 trillion
Aerodynamics
Aircraft systems
Materials and weight reduction
New energy sources,e.g.:
Battery power
New structural elements, e.g.:
Strut-braced wing
New propulsion, e.g.:
Open rotor
Ground vehicles also contribute to emissions
Issue for airport vicinity
Evolutionary only
up to
-20%
SAF
ICAO standards
airside and landside
Sustainable aviation fuels (SAF)
Will contribute largest part to 2050 CO reduction goal
Fast uptake of drop-in fuels once available
