TUD Dresden University of Technology, as a University of Excellence, is one of the leading and most dynamic research institutions in the country. Founded in 1828, today it is a globally oriented, regionally anchored top university as it focuses on the grand challenges of the 21st century. It develops innovative solutions for the world's most pressing issues. TUD has established the Research Training Group "AirMetro - Technological & Operational Integration of Highly Automated Air Transport in Urban Areas" (RTG 2947), funded by the German Research Foundation (DFG). This interdisciplinary group, involving five faculties and the German Aerospace Centre (DLR), will conduct research on 11 research topics. The goal is to address the technical and social challenges of Innovative Air Mobility (IAM), considering ecological, economic, technological, and sociological factors. The RTG's structured PhD program aims to train young researchers in highly automated, networked mobility, featuring international collaboration with mentors from the USA, Asia, and Europe. TUD and the RTG embody a university culture that is characterized by cosmopolitanism, mutual appreciation, thriving innovation and active participation. For TUD diversity is an essential feature and a quality criterion of an excellent university. Accordingly, we welcome all applicants who would like to commit themselves, their achievements and productivity to the success of the whole institution.

Title:Optimization of Innovative Air Mobility Networks Operating

Supervisor:Prof. Dr.-Ing Hartmut Fricke, Chair of Air Transport Technology and Logistics and co-supervised by at least one additional professor plus an international tutor of the RTG

Description of the PhD topic:

Innovative Air Mobility (IAM) networks are currently being designed in cities worldwide. These networks rely on electrically powered vertical takeoff and landing aircraft whose operational performance is strongly influenced by environmental conditions. Variations in vehicle range and endurance directly affect network design, including node density, routing, and overall operational feasibility.

Unlike conventional air transport, IAM networks are characterized by uncertain demand, evolving vehicle technologies, fleet characteristics, and non-static infrastructure requirements. Traditional planning approaches that treat infrastructure and fleet characteristics as fixed inputs are therefore insufficient. This PhD project addresses the need for integrated and adaptive network design methods that jointly consider infrastructure placement, vehicle performance, flight planning, and scheduling under uncertainty.

Building on existing demand-optimized network models, the project explores multi-objective optimization strategies to assess robustness against environmental and demand fluctuations, with the aim of supporting strategically viable and long-lived IAM network infrastructures.

Objectives:

• develop an integrated framework for IAM network operations and design that jointly considers infrastructure placement, fleet characteristics, and scheduling under uncertain and evolving conditions
• extend existing demand-based network optimization models by incorporating vehicle performance sensitivities and environmental influences
• apply multi-criteria optimization methods to assess competing objectives such as coverage, efficiency, robustness, and operational cost
• evaluate the robustness of IAM network concepts against fluctuations in demand and environmental conditions to support long-term operational viability

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 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 curriculum
• supporting scientific graduation work (Bachelor/Master/Diploma) in the subject-specific research field
• regular reporting on research progress to the supervising professors
• publishing the results of the research work individually and in concert with others
• cooperative maintenance of exchange platforms (database, information pages, etc.)
• summarizing the results of the individual PhD study project in a dissertation within the due time of four years
• Successful candidates will work together with an experienced PhD researcher at the Chair of Air Transport Technology and Logistics and together with other chairs being part of the RTG.

Requirements:

• good or very good university degree in aviation, transportation and logistics, computer science or comparable
• knowledge in traffic planning methodologies and in mathematical optimization techniques
• We are looking for first-class graduates with expertise in the RTG-addressed PhD subjects, high interdisciplinary desire to learn and willingness to cooperate, very good verbal and written English communication skills as well as the absolute determination to submit the dissertation after 3 years of research.

We offer:

• Pioneering Research Environment: Shape the future of advanced air mobility through involvement in innovative drone-related projects that bridge technology, urban planning, material sciences, sensors and aviation. With the upcoming Smart Mobility Lab in Lusatia, Saxony, you will have access to state-of-the-art and extensive facilities for experiments. This includes a hall measuring 100x100x30 meters and outdoor space (available from 2027).
• Cross-Disciplinary Collaboration: Immerse yourself in a highly collaborative and interdisciplinary research environment, where you'll work alongside experts from fields such as engineering, data science, urban studies, and aerospace.
• Skill Development: Our extensive qualification concept goes beyond research, offering targeted training in drone technology, data analytics, regulatory aspects, project management, and leadership skills. This ensures you graduate not only as a specialist in your field but also as a well-rounded professional.
• Global Networking: Collaborate with our network of local and international partners, fostering connections that transcend geographical boundaries and enrich your academic and professional network. This includes a paid research stay abroad for three months.
• Career Advancement: Receive dedicated support for fellowship applications and tailored guidance for your career.
• Quality of Life in Dresden: Experience a high quality of life in Dresden, with its dynamic urban scene, relatively affordable living, rich cultural offerings, and vibrant nightlife.
