Aim of the project

• Investigations on environmentally friendly and cost effective freighter aircraft configurations

• “Environmentally friendly” due to:– Low fuel consumption

– Low emissions (CO2, NOx)

– Future fuels (Liquid hydrogen – LH2, Synfuel, Biofuel)

– Low noise level

ALOHAAircraft Design for Low Cost Ground Handling

• Total: 510 k€

• HAW: 140 k€

• 2 years and 4 month

• Partner:

Airbus, Airport Research Center GmbH, Hamburg Airport

• Sponsor:

Federal Ministry of Education and Research

22

Background

• Low Cost Airlines (LCA) fly today with mostly Boeing B737 und Airbus A320.

• Ryanair was the first European LCA founded in 1985.

• The B737 was developed in the 60th, the A320 in the 80th - also still at a time, where LCA requirements were not included intothe aircraft design.

• Aircraft manufacturers started to work on replacements for themodels B737 and A320.

• ALOHA helps to include LCA requirements already from the start into the development of the successors of current single aisleaircraft.

23

Turn Around Time and Cost Reduction

• New aircraft designs (lower sill height, ...)• Faster boarding and deplaning (new door arrangement)• Simpler baggage loading (moving belt, sliding carpet, ...)• Autonomous boarding (integrated stairs, ...)• Autonomous push-back• Autonomous taxiing• New handling operations• Less airport charges
