Mitigating the Climate Impact from Aviation: Achievements and Results of the DLR WeCare Project
Volker Grewe,Katrin Dahlmann,Jan Flink,Christine Frömming,Robin Ghosh,Klaus Gierens,Romy Heller,Johannes Hendricks,Patrick Jöckel,Stefan H. E. Kaufmann,Katrin Kölker,Florian Linke,Tanja Luchkova,Benjamin Lührs,Jesper van Manen,Sigrun Matthes,Andreas Minikin,Malte Niklaß,Martin Plohr,Mattia Righi,Simon Rosanka,Angela R. Schmitt,Ulrich Schumann,Ivan Terekhov,Simon Unterstrasser,Margarita Vazquez-Navarro,Christiane Voigt,Kai Wicke,Hiroshi Yamashita,Andreas Zahn,Helmut Ziereis +30 more
TL;DR: The WeCare project (Utilizing Weather information for Climate efficient and eco-efficient future aviation) as mentioned in this paper aimed at finding solutions for reducing the climate impact of aviation based on an improved understanding of the atmospheric impact from aviation by making use of measurements and modeling approaches.
Journal ArticleDOI
A Concept for Multi-Criteria Environmental Assessment of Aircraft Trajectories
Sigrun Matthes,Volker Grewe,Katrin Dahlmann,Christine Frömming,Emma A. Irvine,Ling L. Lim,Florian Linke,Benjamin Lührs,Bethan Owen,Keith P. Shine,Stavros Stromatas,Hiroshi Yamashita,Feijia Yin +12 more
TL;DR: In this paper, the authors present a mathematical framework for environmental assessment and optimisation of aircraft trajectories based on environmental change functions (ECFs), which represent environmental impact due to changes in air quality, noise and climate impact.
Journal ArticleDOI
Impact on flight trajectory characteristics when avoiding the formation of persistent contrails for transatlantic flights
TL;DR: In this paper, the impacts on flight trajectories, such as lateral and vertical changes, when avoiding the formation of persistent contrails for transatlantic flights were studied, and the trade-off between the flight time and contrail distance showed a large daily variability, meaning for the same increase in flight time, the reduction in contrail distances varies from 20 to 80 depending on the daily meteorological situation.
Journal ArticleDOI
Newly developed aircraft routing options for air traffic simulation in the chemistry–climate model EMAC 2.53: AirTraf 2.0
Hiroshi Yamashita,Feijia Yin,Volker Grewe,Volker Grewe,Patrick Jöckel,Sigrun Matthes,Bastian Kern,Katrin Dahlmann,Christine Frömming +8 more
TL;DR: The results clearly show that AirTraf 2.0 can find the different families of optimum flight trajectories (three-dimensional) for specific routing options; those trajectories minimize the corresponding objective functions successfully.
Journal ArticleDOI
Wind Tunnel Testing on Start/Unstart Characteristics of Finite Supersonic Biplane Wing
Hiroshi Yamashita,Naoshi Kuratani,Masahito Yonezawa,Toshihiro Ogawa,Hiroki Nagai,Keisuke Asai,Shigeru Obayashi +6 more
TL;DR: In this article, the authors describe the start/unstart characteristics of a finite and rectangular supersonic biplane wing with an aspect ratio of 0.75 and 2.5.
