Analytical Aircraft Design

Development and improvement of the statistical preliminary draft tools, concept studies

The teaching in the field of general and conceptual aircraft design deals with the description of the basic procedures of classic aircraft design (handbook methods) and its critical reflection as well as the necessity of the used methods. In the context of the ‘Aircraft Design Seminar’, the students are regularly given the opportunity to perform an entire aircraft design process by doing group work. The relating scenarios and boundary values are defined in collaboration with the ‘Future Project Office’ of Airbus Industries.

The field of research mainly focuses on the improvement of the statistical preliminary draft tools introduced above and for the development of new design approaches. The emphasis is on analytic methods.

UP Wing

 Ultra Performance Wing

Description of the project

The Ultra Performance Wing project will validate, down select, mature and demonstrate key technologies and provide the architectural integration of “ultra-performance wing” concepts for targeted ultra-efficient Short/Medium Range aircraft (SMR), i.e. 150-250 PAX and 1000-2000 NM range.

The project directly addresses the Clean Aviation objectives: fuel burn reduction of minimum 30% aircraft level, compared to the state-of-the-art reference Aircraft. UP Wing will consider 2 aircraft configurations, covering both exploitation horizons outlined in Clean Aviation impact objectives: a high aspect ratio SAF wing with turbofan engine targeting 10-13% and a dry high aspect ratio wing with open rotor up to 17% energy efficiency efficiency increase on wing level. The dry-wing concept will utilize an alternative energy source which will be located in a rear fuselage tank.

UP Wing will develop the integrated high aspect ratio SAF wing up to TRL4 until the end of this project and will provide concepts studies for several dry wing configurations. The interdisciplinary European consortium, consisting of airframe integrators, industry, research establishments and academia will develop the related enabling technologies covering all relevant engineering disciplines. Ground, wind tunnel and virtual testing are foreseen. Thanks to multidisciplinary optimisation the overall wing design for Configuration 1 will ensure the proper integration of all technologies up to TRL4. These results will be picked up in a second Clean Aviation phase achieving TRL6 until the end of the Clean Aviation programme.

These Clean Aviation objectives are well aligned to the development plans of future aircrafts entering into service in 2035 (SAF SMR & H2 Regional), with 75% market penetration until 2050. Academia involved will ensure proper scientific exploitations via lectures, conference contributions, journal proceedings whereas the industrial partners will mature specific technology bricks to TRL4 and higher.

Contribution of the IFB

The Institute of Aircraft Design will focus on the structural design and evaluation of the strut of the dry wing concept. By fully parametrized finite-element models Design of Experiments are performed. This allows to identify the main design parameters and a detailed model with given boundary conditions can be generated.

UNICADO-II

University Conceptual Aircraft Design and Optimization Environment

Development of a university-based preliminary aircraft design environment

Project description

UNICADO-II is the continuation of UNICADO and aims to maintain and expand the overall system evaluation capability of German aircraft design universities. This includes firstly the creation of the consortium's ability to provide information on current configuration related questions and problems from the aviation industry, and secondly, the development of a comprehensive database for aircraft reference configurations. In UNICADO-II, hydrogen-powered aircraft concepts are being designed in order to evaluate this technology for commercial aviation and, together with industry, to provide a basis for further research. To this end, the two approaches of energy generation using fuel cells and direct combustion of hydrogen are being investigated both on a conventional short-haul configuration certifiable to CS-25 standards and on a blended wing-body (BWB) configuration. In addition to the "products", i.e. the elaborated designs, UNICADO-II aims to develop operational processes in order to provide an easy-to-use, robust, quickly expandable aircraft pre-design software with a meaningful level of data detail in the long term.

Contribution of the IFB
  • Development of a teaching and research concept for and with the aircraft design environment UNICADO

  • Extension of functionalities and increase of accuracy in the modules InitialSizing and SystemsDesign.

  • Technology enhancement in the InitialSizing and SystemsDesign modules for hydrogen-powered aircraft and blended wing-body aircraft.

  • Setup and application of UNICADO in the Aircraft Design Lab for parameter variations of the CeRAS reference.

  • Validation of the overall integrity and functionality of UNICADO through CeRAS redesigns.

H2Avia

Hydrogen in Aviation

Content of the project

First, the contribution of hydrogen as the main energy source in aviation to achieve climate targets is quantified. In addition, the costs and climate impact of the production and transportation of hydrogen and its use in ground operations at the airport are determined. Furthermore, the critical technologies necessary for the introduction of hydrogen are identified, investigated and modeled in detail. These advanced technologies will then be integrated into all relevant aircraft classes. Finally, all technology bricks are combined into a holistic scenario using fleet modeling and life cycle analysis.

Contribution of the IFB

In this project, the University of Stuttgart focuses primarily on hydrogen tank integration and the related new fuselage design methods to be developed for the various aircraft classes. Furthermore, the University of Stuttgart is developing suitable concepts for the thermal management system that needs to be developed due to the new requirements of the different powertrains. The main focus here is to analyze the synergies to be exploited. Finally, the University of Stuttgart supports the main work of the other partners by identifying and examining in detail the safety requirements and certification requirements for the hydrogen supply system of the designed aircraft.

FUTPRINT50

Future propulsion and integration: towards a hybrid-electric 50-seat regional aircraft

Content of the project

The Horizon 2020 research project FUTPRINT50 addresses the need to accelerate the development of hybrid-electric technologies in aviation to ensure CO2-neutral growth of air transport in the future. In more detail, the project will address the key technologies of energy storage, energy harvesting and thermal management system. In addition to advancing the state of the art of these technologies, it will develop design methods. This will include models and tools for evaluating new configurations and for the integration on system and aircraft level. To achieve the ambitious vision of an entry into service by 2035/40, FUTPRINT50 will develop roadmaps to focus future research not only on technology development but also on regulatory aspects.

Contribution of the IFB

The Institute of Aircraft Design (IFB) at the University of Stuttgart holds the overall lead of the FUTPRINT50 research project. In addition, it mainly contributes its expertise in overall aircraft design. In addition to creating suitable evaluation methods, the IFB is investigating various powertrain architectures and selecting the most promising one. A detailed preliminary aircraft design is then prepared. In addition, an open-source branch of an aircraft design tool is being built at IFB to accelerate the development of future hybrid-electric regional aircraft, create reference data sets and share them openly with the community.

GNOSIS

Holistic Evaluation of Electric Flight

Content of the project

Within the scope of GNOSIS a holistic evaluation of electric flight is conducted. For this purpose, the novel possibilities for the propulsion system of a regional aircraft with a (partially) electrified propulsion system are identified. This includes a simplified estimation of the impact on global emissions, local emissions, noise, cost and safety.

Furthermore, a framework for analysing air transportation systems is being developed. It allows a detailed estimation of the potential of different (partially) electrified airplane configurations in the mentioned categories and further takes the aspects of the airplane’s life cycle into account. The generated results are utilized to identify optimised configurations of airplanes with 19 seats and the corresponding scaling effects for airplanes in the class of 9 to 50 seats. 

Contribution of the IFB

The IFB researches the certification of electric and hybrid-electric airplane configurations by analysing existing certification specifications. Since the current certification specifications do not fully cover the novel propulsion systems, different scenarios for future requirements are developed and evaluated. The goal is to identify possible opportunities and risks within the certification requirements.
