Position Overview KU is seeking a highly motivated Post-doctoral Fellow to work on the experimental characterization of the wake of a multi-rotor drone and the interaction of such wakes between multiple drones in formation. The project, within which this position is open, addresses the interaction of Uncrewed Aircraft Systems (UAS) with wakes of other similar craft and wakes of large-scale urban objects such as buildings. Contrary to fixed-wing aircraft, there is very little information and no internationally accepted standards concerning the wake characteristics of Vertical Take-Off and Landing (VTOL) craft for cruise, and ascent/descent, and how such wake will affect the dynamics of neighboring UAS. This is a key challenge to be tackled to ensure safe separation in the foreseen UAS Traffic Management (UTM) system which will have to deal with small VTOL craft operating in a highly constricted urban airspace which is subject to significant environmental flow unsteadiness. In the future, the knowledge gained in this project on the aerodynamics of multi-rotor UAS could be extended to larger, passenger-carrying VTOL platforms (e.g., air taxis) adopting similar design approaches. The post-doctoral fellow will lead the effort in designing the experiment, setting it up in the new KU low-speed wind tunnel facility, and conducting the consequent measurement campaigns and data analyses. The major project work packages are: (i) simulating the drone flight in the wind tunnel and characterizing its wake, and (ii) exploring the sensitivity of such drone to the presence of another drone in close proximity and characterizing their wake interactions. The candidate will have access to state-of-the-art flow measurement equipment, such as High-speed Particle Image Velocimetry (TR-PIV), Stereoscopic (S-)PIV and other, as well as facilities at the new KU Low-Speed Wind tunnel facility. The postdoctoral fellow will have an opportunity to work alongside researchers and graduate students from various backgrounds as part of a wider team. Occasional trips (2 to 3 weeks in duration, with air tickets and per diem) might be necessary to the collaborator facilities at the University of Liverpool (UK), to perform experiments and work collaboratively on results and publications. Therefore, the candidate is expected to have international mobility. The contract is initially for a duration of 1 year, but can be renewed for 1 more year, subject to the employee\xe2\x80\x99s performance appraisal.
