I optimise air conditioning for aircraft

In flight, the air conditioning equipment on a medium-range airliner consumes the most energy after propulsion – using approximately two to three percent of the fuel. I model novel cooling systems to suitably address the increasing heat output of avionics equipment and reduce fuel consumption. Currently, avionics and on-board power systems are cooled using air. Liquid glycol-water mixtures would be both efficient and offer high performance. I use exergetic analysis to investigate where in the life support system the losses occur and thus determine where the potential savings are greatest.


I appreciate the great confidence…

… that is shown in me as a young scientist at DLR. Tasks with great responsibility and extensive design freedom are important to me. After all, in cutting-edge research, one has to develop and follow one’s own visions.
