Interview with

Dr. Anne Göhler-Stroh

Energy Technologies and Power Systems

THE MORE INNOVATIVE THE ENGINE CONCEPT, THE MORE NECESSARY THE HOLISTIC APPROACH.
Dr. Anne Göhler-Stroh

Dr. Anne Göhler-Stroh has been employed at Bauhaus Luftfahrt since July 2015. The 33-year-old engineer is a member of the research focus area “Energy Technologies and Power Systems” as well as an expert in the field of advanced engine architectures.

What is your current research focus, Dr. Göhler-Stroh?

I am investigating the potentials of the “Bottoming Cycle” in combination with a turbofan. The principle of such a concept consists in recovering the residual heat from the exhaust gas of the jet engine and returning it to the Joule-Brayton cycle in energetic form. Thus, better specific fuel consumption and performance than for turbofan or IRA engines arise. The challenges of my work are to choose both engine architecture and medium for the “Bottoming Cycle” in such a way that, despite the complexity and integration requirements, advantages emerge at the overall system level.

What is the relevance of your work for the future of aviation?

The efficiency potential of the turbofan is almost exhausted. At the same time, the targets for engine emissions reduction are very ambitious. Therefore, the transition to a different architecture appears inevitable. In order to be able to make a decision on these alternative architectures tomorrow, we must develop and evaluate new concepts today. The “Bottoming Cycle” is just one of many possibilities.

Which methods and tools are you using?

Most of the methods are developed in-house in MATLAB. This ranges from engine simulations and thermodynamic methods to specific simulation programmes for subsystems, such as piston engines or gearboxes, for example. This gives us the freedom to find tailored solutions for our needs. A high degree of flexibility is crucial, especially when evaluating innovative engine concepts.

In what way does Bauhaus Luftfahrt provide the best environment for your research?

Bauhaus Luftfahrt is located at the interface between research and industry. It is thus constantly exposed to the conflict between new approaches and technical feasibility. In other words, it perfectly describes my idea of engineering: to give freedom to ideas and creativity, without the economic pressure of industry, but under its requirements for product proximity and feasibility.
In addition, the permanent involvement in a wide range of projects helps you to get to know the demands and challenges of various aviation players. And last, but not least, Bauhaus Luftfahrt holds a very cooperative position on the topic Family and Career with individual work models.

What were your stations before you joined Bauhaus Luftfahrt?

After a classic French engineering degree in mechanical engineering followed by a specialisation in fluid mechanics and power engineering, I came to MTU Aero Engines in Munich. I worked there for more than six years, first in thermal engineering and then in predesign, where I achieved my dissertation in the field of optimised recuperative systems for turboshaft engines in the light-helicopter segment. After completing my doctoral degree, I started work at Bauhaus Luftfahrt, where I am looking forward to shaping the aviation of tomorrow, or even the day after tomorrow.
