Gesuchter Beruf:PhD- Researcher Position B1.C: Experimental Study of Wing with LFC Suction Using Advanced Methods
Beschreibung:Background: TU Braunschweig has defined one of its core research areas to create safe, efficient and sustainable mobility for the future. In aviation research, we follow an interdisciplinary research concept, jointly with DLR and Leibniz University Hannover, within the Center of Excellence SE2A ( The project defines scientific and technological foundations for a sustainable future global air transport system to meet the mobility demands by introducing new aircraft technologies, new energy storage and conversion approaches, and fundamental changes to infrastructure and traffic management.

The Junior Research Group (JRG) “Flow Physics of Laminar Wing and Fuselage” is a part of the core research area “System Platforms”. Based on conceptual design studies, flow laminarization of the wing, fuselage and empennage by Boundary Layer (BL) suction offers large gains in overall aircraft efficiency. Leveraging these gains for future aircraft calls for new knowledge on flow-control design of 3D wings and fuselages.

Expected research focus for B1.C position: How much laminar flow can be obtained on the wings and fuselage? A novel wing design for optimal pressure distribution will be developed. First, an optimal airfoil with suction BL will be designed for un-swept wings of a short-range aircraft. The research will be extended to the design of higher-speed airfoils with suction, for medium-range aircraft with transonic swept wings.
This research focuses on wind tunnel testing of 2D airfoils and 3D wings with suction-system under subsonic and transonic flow conditions. The objectives are:
1. To study the features of the suction boundary layer (SBL) experimentally
2. To verify and validate the numerical methods and assets with the flow transition prediction
3. To demonstrate the suction-system prototype on a finite wing

The position will closely collaborate with the other PhD-Researchers within the JRG B1 and other groups of the SE2A Cluster. The doctoral researcher will have access to the most recent flow simulation software and solvers provided by DLR and TU Braunschweig.

Who we are looking for: We are seeking excellent, enthusiastic, and self-motivated researchers with very good communication skills to join our research team as a PhD candidate. Applicants are expected to have:
• Outstanding candidates who have completed or are in the process of completing a Master Degree from a recognized university or institution in Aerospace Engineering, Mechanical Engineering, Applied Physics or comparable field
• Excellent communication skills in English (written and spoken) are required.
• Solid knowledge of fluid mechanics, especially laminar-turbulent transition and experimental methods.
• Experience with one or more of the following techniques: force balances, surface pressure measurements, Particle Image Velocimetry (PIV), and wind tunnel testing
• Good CAD skills
• Familiarity with advanced manufacturing technology is an advantage
