6608 Global import shipment records of Propeller with prices, volume & current Buyer's suppliers relationships based on actual Global export trade database.

This database contains the numerical results obtained by ONERA on the configuration A1, using ZDES mode 2 and ZDES mode 3 methods. The ZDES mode 3 approach offers an explicit resolution of the turbulent scales present in the outer region of the flat plate boundary layer and their interaction with the propeller.

This database contains the acoustic prediction results of DLR for a single operating point of the B1 configuration investigated in the framework of the European project ENODISE. In this configuration, three identical propellers with 6 blades are mounted at leading-edge of a wing (puller configuration). The results presented here can be compared to the measurements carried out by the Technical University of Delft, when these are available. The experimental results should be also saved on the ZENODO repository (use the key word ENODISE).

The investigated operating point as calculated in the prediction is:

• Uinf = 30 m/s, advance ratio J=0.8.

The DLR prediction results were obtained using the analytical approach implemented in the DLR in-house program PropNoise coupled to the blade element momentum theory.

The interaction with the wing is accounted for in a simplistic way as explained in the detailed documentation B_documentation.pptx.

Only, the results for tonal noise are available in this database. Three cases can be investigated separately: a single isolated propeller, 3 distributed propellers, three distributed propellers interacting with the wing.

The DLR results are saved in h5 files, which can be read with e.g. Python.

The ONERA numerical database on configuration B1 deals with the scattering effects of 3 side-by-side puller propellers installed upstream a wing profile in a flow, using an in-house 3-steps-chaining-method. The aim of this work has been to evaluate the ability of the method to predict the scattering effects on the sound pressure level and its directivity.

The two operating points that have been studied are: • U∞ = 30 m/s, J = 0.8, AoA = 2°, with a blade phase-angle Φ=0° between the middle and the side propellers • U∞ = 30 m/s, J = 0.8, AoA = 2°, with a blade phase-angle Φ=10° between the middle and the side propellers

The present configuration follows the one described in TUD experimental contribution for configuration B1.

A synthetized description of the numerical method including some important details and results will be included in the file ONERA_B1_configuration.pptx.

The ONERA database contains numerical results about aerodynamic performances (thrust, torque and efficiency). It also includes pressure and sound pressure levels on the arcs microphones positions of TUD experimental configuration. Datas are stored in .dat and .plt format files.

This database contains the acoustic prediction results of DLR for a single operating point of the A1 and A2 configurations investigated in the framework of the European project ENODISE. In these configurations, a single two-bladed propeller is immersed in a boundary layer. The present results can be compared to the measurements carried out by the University of Bristol and the University of Twente for different boundary layer characteristics. The experimental results are saved elsewhere on the ZENODO repository. The investigated operating point as calculated in the prediction is: Uinf = 33 m/s, 6500 rpm, advance ratio J=1. The experimental measurements were conducted at a slightly lower freestream velocity. The DLR prediction results were obtained using the analytical approach implemented in the DLR in-house program PropNoise coupled to the blade element momentum theory. The calculations were informed by the hot-wire measurements carried out in the boundary-layer as the propeller was removed. Refer to the two references cited below to obtain more information about the theory that was applied to obtain the results: S. Guérin, T. Lade, L. Castelucci, I. Zaman, Tonal noise emission by a low-Mach low-Reynolds number propeller ingesting a boundary layer, 29th International Congress on Sound and Vibration, 10-13 July 2023, Prague (CZ). S. Guérin, T.

The results for tonal and broadband noise are saved separately. The DLR results are saved into an h5 file, which can be read with e.g. python.

Purpose - This project incorporates methods for propeller efficiency estimation into a preliminary sizing tool for large aircraft certified for CS-25 respectively FAR Part 25. --- Methodology - Variable pitch propellers are considered. For them, previously collected methods for propeller efficiency estimation are evaluated and used. The resulting preliminary aircraft sizing tool is evaluated with a redesign of the ATR 72-600. --- Findings - Propeller efficiency estimation methods are based on experience or theory and are defined in diagrams or equations. The main parameters with an influence on propeller efficiency are cruise speed, air density and propeller disc diameter. Furthermore, friction and shock waves (occurring at high Mach numbers) have a large influence on the propeller efficiency. When aerodynamic effects at high Mach numbers are not considered, estimation methods yield maximum propeller efficiency at maximum speed. --- Research Limitations - The influence of high Mach number on propeller efficiency needs to be evaluated further. Propeller efficiency methods are referenced and explained, but not derived. --- Practical Implications - Aircraft preliminary sizing works with automatic calculation of propeller efficiencies. User look-up of efficiencies from diagrams is not required anymore. --- Social Implications - The preliminary sizing tool for large propeller driven aircraft is openly available. Therefore, the potential of future propeller driven aircraft can be discussed by the public. --- Originality - A didactically enhanced design, redesign, and optimization tool (on preliminary sizing level) for large propeller driven aircraft is made openly available. It is especially suited for students and fills a perceived gap.

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.

All following parameters are kept constant in the present simulations:

Free-stream velocity u_inf = 32 m/s,

Propeller tip clearance d/D = 0.002,

Propeller position inside the duct x/D = -0.0627.

Five simulations have been realized by varying the installation (with or without the S-plate) and the propeller rotation speed:

Isolated propeller (without the S-plate), N = 6000 rpm, 8000 rpm, 11000 rpm,

Installed propeller (with the S-plate), N = 6000 rpm, 8000 rpm.

The predictions were obtained using the ProLB solver which is based on the Lattice Boltzmann method (http://www.prolb-cfd.com/). Aerodynamic and acoustic results are provided for each simulation. One-dimensional results are saved into ASCII column files (.dat extension) while geometry and raw flow extractions are saved into HDF5 CGNS files (.cgns extension). README.txt files are included for detailed description of the data.

This database contains the aeroacoustic numerical results generated by Siemens Industry Software (SISW) for the B2 configuration investigated in the framework of the European project ENODISE. In this configuration, a six-blade propeller mounted on a support is studied for two operating points with and without flow. The operating points correspond to conditions 65 and 66 of the experimental campaign carried out at Ecole Centrale of Lyon (see H2020 Enodise: Experimental dataset configuration B2 ECL, https://zenodo.org/record/7925336).

The two investigated operating points are:

Uinf = 0 studied numerically using detached-eddy simulation combined with finite-element method for acoustics

Uinf = 22 m/s studied numerically using large-eddy simulation combined with finite-element method for acoustics

The SISW aeroacoustic results have been obtained using CFD software Simcenter STAR-CCM+ coupled with acoustic software Simcenter 3D Acoustics. The hydrodynamic and acoustic interactions between the propeller and its support are taken into account in the numerical simulations.

More information about the numerical setup and results can be found in the documentation included in the database.

The data are saved in dat files.
