(author), Deck, K.T. (author)Given the comparably high impact of aircraft emissions, especially their non-CO2 effects, on climate in the order of 5%, aviation stakeholders are required to act to reduce the warming effects of air traffic. Besides new operational procedures, like e.g. climate-optimized routing, this demands the development of completely new global-warming...abstract 2020

Daumas, L. (author), Dinh, Q.V. (author), Kleinveld, S. (author), Rogé, G. (author)Preliminary results on shape optimization of a wing-body configuration aiming at reducing sonic boom overpressure will be discussed. The optimization process uses a CAD modeler and an Euler CFD code with adjoint. Thickness, scale, twist and camber at section level were used to obtain gains in ground pressure signature.conference paper 2006

Proesmans, P. (author), Vos, Roelof (author)Sustainable aviation fuel (SAF) and liquid hydrogen are currently being studied to replace kerosene in commercial aviation to reduce global warming. In this study, the question is how do the airplane design variables change when minimizing the global warming impact of aircraft powered by SAF or LH2? Secondly, how do these aircraft compare in...conference paper 2022

Hoogreef, M.F.M. (author), Bonnin, V.O. (author)Various research initiatives in hybrid-electric/sustainable aviation typically address only a single vehicle or single vehicle class. However, novel propulsion and energy solutions can be expected to be differently applied in different vehicle classes. The objective of the EU funded research project CHYLA (Credible HYbrid eLectric Aircraft) is...conference paper 2022

(author), Vos, Roelof (author), Lührs, Benjamin (author), Niklaβ, Malte (author), Dedoussi, I.C. (author)The aircraft’s environmental performance on fleet level is so far completely decoupled from the design process. The climate impact from aviation arising from non-CO2 effects are largely independent from CO2 emissions, but rather depend on the atmospheric state. Previously complex climate-chemistry models were used to evaluate the non-CO2...conference paper 2022

Thijssen, R. (author), Proesmans, P. (author), Vos, Roelof (author)This paper studies the climate impact of propeller aircraft which are optimized for either minimum direct operating costs, minimum fuel mass, or minimum average temperature response (ATR100). The latter parameter provides a measure of the global warming impact of the aircraft design, considering both CO2 and non-CO2 effects. We study turboprop...conference paper 2022

Boogaart, T.E. (author), Hoogreef, M.F.M. (author), Gangoli Rao, A. (author)Decades of improvements of engine efficiency on internal engine components through better materials, design methods and novel fabrication techniques have resulted in fuel consumption reductions. Another major factor for improving engine fuel consumption has been the increase of bypass ratio. However, this has a significant impact on engine...conference paper 2022

(author)An innovative aircraft design of the Collaborative Research Centre (SFB) 880 features a new active high-lift system. This high-lift system is comprised of a droop-nose leading edge device and a Coanda flap as the trailing edge device. It offers very high lift coefficients and thus the ability to operate at airports that have reduced runway...conference paper 2016

Proesmans, P. (author), Morlupo, F. (author), Santos, Bruno F. (author), Vos, Roelof (author)To reduce the climate impact of aviation, researchers are studying the replacement of fossil kerosene with liquid hydrogen and/or drop-in sustainable aviation fuel (SAF). These fuels can bring significant reductions in CO2 emissions and can offer savings in terms of non-CO2 climate effects. In addition, tube-and-wing aircraft can be optimized to...conference paper 2023
