Full-text available
Green liquid hydrogen (LH2) could play an essential role as a zero-carbon aircraft fuel to reach long-term sustainable aviation. Excluding challenges such as electrolysis, transportation and use of renewable energy in setting up hydrogen (H2) fuel infrastructure, this paper investigates the interface between refueling systems and aircraft, and the...
Article
Aircraft powered by green hydrogen (H2) are a lever for the aviation sector to reduce the climate impact. Previous research already focused on evaluations of H2 aircraft technology, but analyses on infrastructure related cost factors are rarely undertaken. Therefore, this paper aims to provide a holistic overview of previous efforts and introduces...
Conference Paper
The ambitious goals of Flightpath 2050 [1] for a sustainable air transport are being pursued by several pro-jects. In the European Clean Sky 2 project NACOR (New innovative Aircraft Configurations and Related issues), ONERA and DLR collaboratively investigate the potential of innovative unconventional aircraft archi-tectures to reduce fuel consumpt...
Conference Paper
In this paper, the preliminary aircraft design tool openAD is presented. Over the past years the DLR has developed a multidisciplinary and multifidelity design environment for aircraft design to evaluate and assess various concepts and technologies at aircraft level. Thereby, a valid and consistent design can be derived by a minimum set of top-leve...
Conference Paper
The potential of unconventional configurations to reduce the fuel consumption of future aircraft is investigated in the European Clean Sky 2 (ITD Airframe) ONERA-DLR project NACOR (New Aircraft Concepts Research - Call for Core Partners Wave 1). Two design missions are considered: a short/medium range mission (SMR) based on the requirements of an A...
Conference Paper
In the Clean Sky 2 Large Passenger Aircraft (LPA) program the potential of innovative hybrid electric propulsion (HEP) air vehicle concepts has been investigated by the projects ADEC (Advanced Engine and Aircraft Configuration) and NOVAIR (Novel Aircraft Configurations and Scaled Flight Testing Instrumentation). In a combined effort the members of...

Design eines 19-Sitzer Hybrid-Flugzeuges mit 200km vollelektrischen Flug Reichweite und mit Gasturbinen-Range-Extender für Flugreserven. Dir Range-Extender ermöglichen auch eine normale Payload-Range Capability mit einem Ferry-Missionsreichweite von ca. 3000 km. Das design ist basiert auf Stand der Technik elektrische Komponenten.
Conference Paper
Konzeptionelle Design-Studie eines Hybridflugzeuges das auf die A320neo basiert. Das ziel des Antriebstranges ist den Off-Design-Verbrauch zu minimieren (z.B. Taxi oder Sinkflug). Das Konzept ist bewertet hinsichtlich Treibstoffverbrauch auf globale Flottenebene und auf US-Markt Flottenebene, beide basierend auf reale Daten von 2018.

Conference Paper
The work introduces the Aeroelastic Engine, a module under development at DLR to support physics-based modeling and analysis of the complete flexible aircraft for preliminary multidisciplinary design optimization (MDO) applications in a collaborative environment. The paper presents the implemented structural modeling, the analysis capabilities, and...
Conference Paper
Recent international goals for the future development of aviation emphasize the improvement of performance metrics of air transportation systems. Since traditional design processes typically target only individual system elements, like aircraft or air transportation networks, it appears desirable to integrate these different efforts into a single o...
Conference Paper
Full-text available
Advanced aircraft pre-design methodologies tend to involve an increasing amount of disciplines in a concurrent way. Previous research has advanced the capabilities of interlinking design tools and creating automated, multidisciplinary analysis and design workflows. A central challenge herein is found in the practical management of disciplinary know...
Conference Paper
A Multidisciplinary Design and Optimization (MDO) methodology is presented, which uses a physics-based modeling approach for the preliminary structural design of unconventional aircraft configurations. Therein, static as well as dynamic aeroelastic stability constraints are accounted for at the early stage of the design process. A functional parame...
Conference Paper
The paper introduces a functional shape parametrization approach for the design and the optimization of unconventional aircraft configurations. The proposed design methodology is tailored for the preliminary design stages, and it is based on the use of mixed fidelity simulations. The approach is integrated in the DLR collaborative design framework,...
Conference Paper

In the eort to achieve carbon neutral growth on the path to a zero emission future in aviation IATA outlined its \technology roadmap for environmentally sustainable aviation" (TERESA) initiative bringing together manufacturers, scientists, government agencies, in- frastructure providers and airlines. Under this initiative DLR and ASDL conducted the...
Article
*† ‡ A novel flexible preliminary aircraft design system is presented which builds on DLR’s collaborative design environment. The system utilizes analysis modules, which are developed and provided by DLR disciplinary experts, and the unified data format CPACS for interdisciplinary coupling. The preliminary aircraft design system allows for physics...
Conference Paper

This paper introduces an approach to enhance the predesign stage for unconventional aircraft configurations. When prior knowledge is not available, a novel design space has to be explored thoroughly and higher fidelity analysis codes may be employed. A promising recently introduced shape parametrization technique is implemented for the development...
Article
Before the detailed design of a new aircraft can be initiated, basic design parameters have to be defined and evaluated in the preliminary aircraft design. For this task fast and accurate methods are required to achieve results in an adequate computing time. This study analyzes the differences in using finite shell elements instead of beam elements...
