Bauhaus Luftfahrt e.V.

Bauhaus Luftfahrt is a public research institution funded by the four aerospace companies Airbus Group, Industrieanlagen-Betriebsgesellschaft (IABG), Liebherr-Aerospace and MTU Aero Engines as well as grants of the Bavarian Ministry for Economic Affairs, Infrastructure, Transport and Technology. The non-profit association is an internationally-oriented think tank. The team of around 50 employees deals with the future of mobility in general and with the future of air travel in particular. The goal of the research work is to consider the complex system of aviation from technical, economic, social and ecological perspectives in a holistic approach. Amongst others, expertise is gained in the field of aircraft design and assessment as well as technology assessment based on profound physical descriptions. Due to the strong cooperation with national as well as international academia, research institutes and industry partners, BHL was able to successfully contribute to different EU projects (SWAFEA, CREATE, NEWAC, DREAM, LEMCOTEC, SOLAR-JET, DisPURSAL, MorphElle or E-BREAK) regarding organisational/administrative as well as scientific tasks.
Through a multitude of previous and ongoing research projects , as well as independent research and methodological development, BHL has been building up both broad and deep expertise in the conceptual design and aircraft-level integration of advanced propulsion systems. This involves comprehensive sets of methods for multi-disciplinary design integration, performance analysis and system-level optimisation of propulsion systems in general, and, of the piston based “composite cycle” technology concept in particular. Moreover, BHL has developed considerable capability in the multi-disciplinary definition, conceptualisation, simulation and analysis of radical and complex aerospace systems, such as highly advanced transport aircraft concepts.

Role in the project

The central technology investigated by the BHL team for ULTIMATE is the piston based “composite cycle” engine concept. Therefore, the basic principles of the piston based “composite cycle” approach are studied in more detail, aiming at a  multi-disciplinary concept formulation. The aspired investigation includes an architectural exploration of possible piston based “composite cycle” core engine arrangements. As part of this, potential synergies with other technologies studied in the project are explored.
In addition, BHL leads task T2.1 ""Develop year 2050 ATW aircraft model""  where advanced airframe technologies suitable for an advanced tube and wing aircraft layout with an EIS year 2050 are investigated and integrated into a reference aircraft platform serving as a most realistic application scenario for the ULTIMATE propulsion technologies.
