Job description:

In the development of future military aircraft the propulsions system require a very high degree of integration into the fuselage in order to minimize radar signature, in particular to prevent the rotating blades of turbomachinery to be detectable from the outside. Often this is realized by contoured- S-shaped inlets, inducing a substantial amount of inlet distortion to the fan or low-pressure compressor. This results in a potentially reduced stability margin and in general compromised fan operability and performance.

The focus of the work is to better understand this complex interaction by application of modern CFD methods and derive corresponding design patterns to account for those effects during the design phase already.

In greater detail the following topics shall be addressed during the tenure:

  • application and further development of the institutes design and assessment methods for turbomachinery with focus on the design of highly embedded systems including incoming flow distortions in order to achieve a high degree of distortion tolerance

  • derivation of design patterns and correlations using reduced order modelling reflecting the complexity of the physical problem

  • detailed assessment of different aero engine fans with respective integration by means of high-fidelity URANS and Harmonic Balance (HB) simulations in order to verify the design correlations

  • designing and optimizing the intake/fan system by application of the developed methodology

  • coupling of the results with the engine cycle and respective overall aircraft design

The possibility for the project work to result in a PhD is given in principal and encouraged.

This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany's largest scientific organisation.
