37731: Aerospace Engineer, Mechanical Engineer or similar - Development and implementation of an aeroacoustic simulation method for installed propulsors

German Aerospace Center (DLR)

Braunschweig, Germany

Work group:

Institute of Aerodynamics and Flow Technology



Area of research:

Scientific / postdoctoral posts



Job description:


The position reflects the participation in the Excellence cluster SE2A led by TU Braunschweig. The objective is to develop a non-empiric simulation method allowing to predict sourcewise and radiationwise the noise generated as a result of the installation of propulsors on largely arbitrary aircraft configurations. Subsequentially, the acoustic propulsor  integration is to be investigated for various aircraft configurations proposed by partners in SE2A. 


Development and implementation of an aeroacoustic simulation method for installed propulsors


literature study on respective simulation methods development of a concept for fast, non-empiric prediction of aerodynamic source noise due to the integration of propulsors at an aircraft planning of implementation of simulation concept into CAA Code PIANO or DISCO++ implementation of postprocessing of CFD data, interface/source description in CAA Code, and  coupling to acoustic wave equation solver FMCAS test of the scheme’s stability as a function of interfaces and computation grids test at isolated propellers with constant and non-constant blade loads (homogeneous oblique inflow), and installed propulsors comparison with (if available) analytical solutions and data from previous projects on installed propellers (projects BNF, CESAR, SFB880). determination of  the prediction accuracy due to model assumptions

Investigation of propulsor integration noise at reference aircraft


definition of a suitable near field metric for the assessment of installation noise as part of aircraft design (co-operation with project SE2A B5-1) implementation of suitable interface for DLR-PANAM Code for the simulation of  the noise radiation of complete aircraft (co-operation with AS-HEL Göttingen) prediction of sourcewise installation noise at three SE2A reference aircraft configurations prediction of complete installation noise including the acoustic interaction with the aircraft geometry for one reference aircraft by coupling of source data into fast wave equation solver FMCAS
