Aerodynamic Analysis of Aftbodies for Future Fighter Configurations

5 Dezember 2019

General:
Many multidisciplinary requirements and constraints are posed on the design of future fighter aftbodies and the corresponding nozzle integration. The engine configuration, nozzle shape, and the consideration of thrust-vectoring are only a few of a variety of major aspects, which need to be considered in the preliminary design process of future fighter configurations. The objectives of this thesis are to obtain a holistic view on the topic and gather relevant sensitivities for the design of future fighter aftbody configurations.


Proposed Activities:
- Literature review of the aerodynamic behavior of aftbodies and nozzle integration
- Generation of one or more (potentially parametric) CATIA models enabling a fast and efficient study of nozzle configurations
- Setup of a computational framework including evaluations of the effect of the computational mesh and the numerical setup (e.g. turbulence model)
- Computational Fluid Dynamics (CFD) investigations to understand the influences of
                 o nozzle shape (circular, rectangular, or other)
                 o nozzle opening angle (“boat tail angle”)
                 o nozzle position and distance
                 o displacement body arrangement
                 o thrust-vectoring provisions
   on the overall aircraft drag and nozzle efficiency /nozzle losses.
- Documentation of the investigated influences and resulting design guidelines


Requirements:
- Course of study Aerospace Engineering, Aeronautical Engineering, or comparable
- Sound basic knowledge of CATIA shape design is mandatory
- Experience in Computational Fluid Dynamics (CFD)
- Knowledge of at least one programming language (e.g. Python)
- Strong interest in aerodynamic design and fighter aircraft
