“…The research activities in general aeroacoustics have a wide variety and 70 years history. Since 2014, these activities have been mostly concentrated on technical applications [101,126,116,185,143]. to these last six reports, the research landscape in aeroacoustics community in Europe is summarized as a preface.…”

This contribution benchmarks the aeroacoustic workflow of the perturbed convective wave equation and the Ffowcs Williams and Hawkings analogy in Farassat’s 1A version for a low-pressure axial fan. Thereby, we focus on the turbulence modeling of the flow simulation and mesh convergence concerning the complete aeroacoustic workflow. During the validation, good agreement has been found with the efficiency, the wall pressure sensor signals, and the mean velocity profiles in the duct. The analysis of the source term structures shows a strong correlation to the sound pressure spectrum. Finally, both acoustic sound propagation models are compared to the measured sound field data.

“…The year 2015 and 2016 were devoted to emerging topics in aircraft design, like "Broadband noise of rotors and airframes" [185,143]. The year 2019 was mostly devoted to the topic "New materials for applications in aeroacoustics", based on urgent needs for sustainable aviation technologies [101].…”

“…On the other hand, there has been an increased interest in the study of high-speed compressible flows recently, due to several recent initiatives to improve aviation efficiency and to control and mitigate aviation noises in the industry [23,45]. Strategies to achieve better propulsion efficiency and noise control demand a comprehensive understanding on the flow dynamics and structures of transonic and supersonic jet flows, which still pose major challenges today despite active research in the area.…”

“…In 2015, ONERA performed the analysis of microphone array data measured during VV05 of VEGA launcher in Kourou, on behalf of ESA [66]. Approximately at the payload fairing level, a 2 m diameter circular array composed of 32 microphones, was implemented on one of the antilightning pylons, oriented toward the exhaust duct, aimed at identifying the location and level of the acoustic sources generated during lift-off.…”

The Council of European Aerospace Societies (CEAS) Aeroacoustics Specialists Committee (ASC) supports and promotes the interests of the scientific and industrial aeroacoustics community on an European scale and European aeronautics activities internationally. In this context, "aeroacoustics" encompasses all aerospace acoustics and related areas. Each year the committee highlights some of the research and development projects in Europe.This paper is a report on highlights of aeroacoustics research in Europe in 2018, compiled from information provided to the ASC of the CEAS. During 2018, a number of research programmes involving aeroacoustics were funded by the European Commission. Some of the highlights from these programmes are summarised in this article, as well as highlights from other programmes funded by national programmes or by industry. Furthermore, a concise summary of the CEAS-ASC workshop "Future Aircraft Design and Noise Impact" held in the Netherlands Aerospace Centre (NLR) Amsterdam in September 2018 is included in this report.Enquiries concerning all contributions should be addressed to the authors who are given at the end of each subsection.
