Comparison of Sustainable Regional Aircraft Concepts [PDF]

open access: yes, 2022
The presentation shows a comparison between three 70-seater aircraft concepts calculated within the DLR's internal EXACT project. All three concepts assume an entry into service of 2040 and are designed for operation with sustainable energy. The first concept is propelled with advanced turboprop engines fuelled by synthetic kerosene. The second concept

Improved quantification of Chinese carbon fluxes using CO2/CO correlations in Asian outflow [PDF]

open access: yes, 2004
[1] We use observed CO2:CO correlations in Asian outflow from the TRACE-P aircraft campaign (February–April 2001), together with a three-dimensional global chemical transport model (GEOS-CHEM), to constrain specific components of the east Asian CO2 ...

Conceptual design and investigation of hydrogen-fueled regional freighter aircraft [PDF]

open access: yes, 2010
This thesis presents the conceptual design and comparison of five versions of regional freighter aircraft based on the ATR 72. The versions comprise four baseline designs differing in their propulsion systems (jet/turboprop) and the fuel they use ...

Overcapacity in regional aircraft production

open access: yes, 2005
Capacity decisions are among the most important operations decisions for companies. One of the potential outcomes of bad decisions is a resulting overcapacity. Although some textbooks treat overcapacity as an issue for individual companies, there are indications that it may be an industry wide issue.
