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. Data are stored in .dat and .plt format files.
