Descripción del proyecto
Nuevas pruebas en aeronaves con propulsión eléctrica distribuida
Las aeronaves con propulsión eléctrica distribuida podrían reducir sustancialmente el consumo de combustible y las emisiones de carbono nocivas. El proyecto financiado con fondos europeos VENUS proporcionará conocimientos fundamentales sobre el rendimiento aerodinámico y aeroacústico de una amplia variedad de sistemas de propulsión eléctrica distribuida mediante simulaciones numéricas y pruebas experimentales en túneles de viento. Los resultados del proyecto deberían mejorar el diseño futuro de nuevas aeronaves de transporte regional. Todos los modelos, datos y documentos generados estarán disponibles gratuitamente para las instituciones de investigación. Unos aviones más aerodinámicos y silenciosos significan un menor consumo de combustible, lo que se traduce no solo en beneficios en cuanto a costes y competitividad, sino también en un menor impacto en el medio ambiente.
Objetivo
Distributed Electric Propulsion (DEP), is one of the propulsion configurations that, taking advantage from the Distributed Propulsion concept, is believed to exploit the benefits of electrical engines to drastically reduce fuel consumption and emissions. In the framework of the topic JTI-CS2-2018-CFP10-THT-08, the proposal VENUS will have the objective to understand the physics behind the aeroacoustics of DEP through a deep theoretical, experimental and numerical study. Appropriate numerical procedures for DEP noise assessment will be set-up and experimental data-set obtained in dedicated wind tunnel tests, will be used both as experimental DEP noise validation reference and for providing support to the identification of the main parameters affecting DEP noise. Technologies for DEP noise reduction will be studied as well and tested experimentally. From the technical standpoint, the VENUS consortium will support the model design, manufacturing and integration by realizing a representative test article for WT parametric aeroacoustic tests, able to allow for configuration changes, in terms of engine-wing and engine-engine installation configurations, and to test the selected noise mitigation technologies. The consortium will develop methods and tools enabling a concurrent aerodynamic and aeroacoustic design of DEP configuration aircraft. The final step will consist in the experimental-numerical assessment of the numerical models. As a practical achievement, the study will support the design of a new regional aircraft configuration, in terms of wing and engines’ installation, to target a DEP which is optimized in terms of aerodynamic and aeroacoustic performance. It is pointed out that all the produced models, data and documents will be open access for other institutions, with the objective to establish an “open test-case” for the whole European scientific community, unique in the aircraft design landscape.
