PHD Thesis
Job description:
You will do research on innovative acoustic treatments for aircraft interior structures to reduce cabin noise with a minimum of weight. This will contribute to a more sustainable aviation in the future. The main objective of your thesis is to develop an acoustic cabin simulator that allows the identification of cabin noise sources by numerical simulation of coupled fluid structure systems. The aircraft cabin is surrounded by various vibrating structures (ceiling and sidewall panel, hatrack, floor) which act as noise sources and contribute differently to the cabin noise depending of the load case. By identifying the most important noise sources for different load cases, effective treatments can be investigated and evaluated in the numerical framework on cabin level. Relevant load cases will be obtained from measurement data of full-scale aircraft on ground or in-flight operation.
Your mission is to develop a numerical framework suitable for the identification of the noise contribution of cabin interior parts. Noise maps of the cabin with vibrating surroundings will be calculated in order to understand sound pressure distributions caused by different parts. Based on this numerical framework the efficiency of individual acoustic treatments of cabin interior parts will be assessed.
You will work in the Smart Structures Department of the DLR-Institute of Composite Structures and Adaptive Systems in Braunschweig Germany. At the same time, you will be enrolled as PhD student at the Otto-von-Guericke University Magdeburg at the chair of Adaptronics of Professor Hans Peter Monner who is also head of the Smart Structures Department of DLR. You will be supervised by very experienced post-doc researchers of the Department and you will be fully integrated into the vibro-acoustics team of the Department.
In addition to your scientific project, you will benefit from further continuing education, which includes secondments (internships), a variety of training modules as well as transferable skills courses and active participation in workshops and conferences.
You will spend three secondment periods at our project partners Silesian University of Technology (Poland), Siemens Industry Software NV (Belgium) and Airbus Operations GmbH (Germany) for a duration of three months for each secondment. During your secondment, your will receive supervision and training at the premises of the receiving organization. Secondments are mandatory. If you apply for one of the positions then you agree that you will be seconded to other organizations during your contract.
