Initial auralization of a distributed propulsion system equipped with 26 ducted low-speed fans
<p>Illustration of engine noise auralization by DLR Institute of Propulsion Technology obtained with the framework PropNoise, VIOLIN, CORAL. Data associated with the following publication: S. Schade, R. Merino-Martinez, P. Ratei, S. Bartels, R. Jaron and A. Moreau, "<a href="https://doi.org/10.2514/6.2024-3273"><em>Initial Study on the Impact of Speed Fluctuations on the Psychoacoustic Characteristics of a Distributed Propulsion System with Ducted Fans</em></a>", 30th AIAA/CEAS Aeroacoustics Conference, Rome, Italy, 04-07 June, 2024.</p> <p>Selected binaural audio files to illustrate the impact of rotational speed fluctuations on the noise characteristics of a distributed propulsion system equipped with 26 ducted, low-speed fans. Please note that the sound pressure amplitudes are normalized to 110dB for the reference turbofan case and to 90dB for the cases with distributed fans.</p> <p>The corresponding time signals and spectrograms are available in the associated conference paper in Figures 4-6.</p>
H2020 ENODISE: ONERA Numerical Aeroacoustic Database Configuration A2-Ducted
<p>This database contains the numerical results obtained by ONERA on the configuration A2-ducted of the H2020 ENODISE project. In this configuration, a ducted propeller is placed above an S-plate to ingest an adverse pressure gradient boundary layer in a partially buried configuration. The present results can be compared to the measurements carried out by the University of Bristol.</p> <p>All following parameters are kept constant in the present simulations:</p> <ul> <li>Free-stream velocity <em>u_inf</em> = 32 m/s,</li> <li>Propeller tip clearance <em>d/D</em> = 0.002,</li> <li>Propeller position inside the duct <em>x/D</em> = -0.0627.</li> </ul> <p>Five simulations have been realized by varying the installation (with or without the S-plate) and the propeller rotation speed:</p> <ul> <li>Isolated propeller (without the S-plate), <em>N</em> = 6000 rpm, 8000 rpm, 11000 rpm,</li> <li>Installed propeller (with the S-plate), <em>N</em> = 6000 rpm, 8000 rpm.</li> </ul> <p>The predictions were obtained using the ProLB solver which is based on the Lattice Boltzmann method (<a href="http://www.prolb-cfd.com/">http://www.prolb-cfd.com/</a>). Aerodynamic and acoustic results are provided for each simulation. One-dimensional results are saved into ASCII column files (<em>.dat</em> extension) while geometry and raw flow extractions are saved into HDF5 CGNS files (<em>.cgns</em> extension). <em>README.txt</em> files are included for detailed description of the data.</p> <p> </p>
