Research Associate ­­/­­ PhD Student (m­­/­­f­­/­­x)

Description of the PhD topic: (subproject T7) In Urban air mobility, a high wind sensitivity of UAVs as well as a sensitive interaction of the natural frequency of the UAVs with the surrounding turbulence are expected. These boundary conditions must be considered in the regulatory Certification Specifications. The PhD topic consists of two parts, the weighting of which can be adjusted. First, natural frequencies of different UAV categories for different power settings shall be modelled. Second, based on mesoscale fluid dynamic simulations, microclimatic and turbulence modelling procedures in urban environments shall be performed. Subsequently weather-and turbulence-related limit values shall be formulated and compared with corresponding verifications (e.g., stable flight behavior at wind speeds of up to 14 m/s and high turbulence). Tasks: Independent and cooperative qualification through scientific research within one of the PhD study projects on offer; training in the technical tasks of the individual dissertation topics through study of the literature and in making the objectives more precise; working on the individual PhD study project with experimental, numerical, metrological or empirical focus in collaboration with other RTG members (fellow students and supervising professors); implementation of the planned research program, evaluation and interpretation of the results and transferring them to a RTG internal ex-change platform, elaboration and presentation of the state-of-the-art in the respective research fields; participation in lectures, workshops and summer schools according to the guidelines of the RTG cur-riculum; supporting scientific graduation work (Bachelor/Master/Diploma) in the subject-specific re-search field; regular reporting on research progress to the supervising professors; publishing the re-sults of the research work individually and in concert with others; cooperative maintenance of ex-change platforms (database, information pages, etc.); summarizing the results of the individual PhD study project in a dissertation within the due time of 3,5 years. Successful candidates will work together with approx. 18 PhD candidates at the Chair of Air Transport and Logistics and together with other chairs being part of the RTG.
