Noise source separation in low-Reynolds multi-propeller systems: experimental techniques and post-processing approaches Gabriel Pereira Gouveia da Silva, João Paulo Eguea, Fernando Martini Catalano 54th International Congress and Exposition on Noise Control Engineering Internoise 2025, 2025 Small propellers and rotors operating at low Reynolds numbers exhibit predominantly broadband noise, so that the tonal noise at the blade passing frequency and its higher harmonics (more significant in large-scale propellers and rotors) is masked by broadband noise in acoustic spectra obtained from reduced-scale wind tunnel tests. Thus, to evaluate the decay of blade passing frequency harmonics in rotating noise sources obtained from reduced-scale tests, it is necessary to apply techniques capable of synchronously measuring the angular position of each blade along with the acoustic pressure. In this context, techniques such as ensemble averaging can be employed to enable the measurement of noise associated with the blade passing frequency and its higher harmonics even when broadband noise predominates. This work describes the experimental setup and post-processing techniques used at the Experimental Aerodynamics Laboratory of the São Carlos School of Engineering, University of São Paulo, to perform noise source separation in small, low-Reynolds-number propellers and rotors in multi-propeller and multi-rotor systems.
Optimization of Structures and Composite Materials: A Brief Review André Ferreira Costa Vieira, Marcos Rogério Tavares Filho, João Paulo Eguea, Marcelo Leite Ribeiro Eng, 2024 Neural networks (NNs) have revolutionized various fields, including aeronautics where it is applied in computational fluid dynamics, finite element analysis, load prediction, and structural optimization. Particularly in optimization, neural networks and deep neural networks are extensively employed to enhance the efficiency of genetic algorithms because, with this tool, it is possible to speed up the finite element analysis process, which will also speed up the optimization process. The main objective of this paper is to present how neural networks can help speed up the process of optimizing the geometries and composition of composite structures (dimension, topology, volume fractions, reinforcement architecture, matrix/reinforcement composition, etc.) compared to the traditional optimization methods. This article stands out by showcasing not only studies related to aeronautics but also those in the field of mechanics, emphasizing that the underlying principles are shared and applicable to both domains. The use of NNs as a surrogate model has been demonstrated to be a great tool for the optimization process; some studies have shown that the NNs are accurate in their predictions, with an MSE of 1×10−5 and MAE of 0.007%. It has also been observed that its use helps to reduce optimization time, such as up to a speed 47.5 times faster than a full aeroelastic model.
