Descrizione del progetto
Meno rumore e meno emissioni grazie a sistemi di propulsione aeronautica innovativi e meglio integrati
Il rumore e le emissioni di gas serra generate dagli aerei hanno un impatto negativo sulla salute umana e sull’ambiente. Per ridurre il rumore e le emissioni gassose, il progetto ENODISE, finanziato dall’UE, si propone di migliorare l’integrazione dei nuovi sistemi di propulsione degli aeromobili con la cellula. Per far questo, studierà le problematiche chiave dell’integrazione propulsione-cellula e costruirà una solida base di conoscenze e metodi. Il progetto indagherà le condizioni ottimali dell’integrazione avvalendosi di un’innovativa metodologia sperimentale abbinata a simulazioni ad alta fedeltà e ad approcci di modellizzazione di basso livello. Implementerà inoltre modifiche di forma e tecnologie innovative di controllo del flusso/acustico per massimizzare l’efficienza aerodinamica e ridurre al contempo gli effetti negativi dell’installazione. Il piano di ricerca proposto dovrebbe portare a una migliore progettazione dell’integrazione con effetti negativi minimi sull’installazione.
Obiettivo
ENODISE is an enabler project aimed at reducing aircraft gaseous and noise emissions by improving the integration of the propulsion system with the airframe. Complex aerodynamic and acoustic engine-airframe interactions are involved, which must be better understood to yield the expected gains. ENODISE will investigate the main propulsion-airframe integration issues at low TRL and build a solid basis of knowledge and methods based on simplified but representative configurations, permitting to assess a variety of integration concepts.
ENODISE will investigate the existence of local/global integration optima via an innovative experimental methodology combined with reduced order modelling and machine learning strategies. Selected configurations will be simulated using methods ranging from low-CPU to high-fidelity. The low-CPU techniques will be employed to verify if the experimentally observed optima can be obtained numerically, and the high-fidelity methods will contribute to the detailed investigation of the aeroacoustic mechanisms in addition to permitting a fine-tuning of the low-cost methods. The work being carried out on relatively low-cost generic configurations, this project will permit spanning a broad parameter space and testing optimization-based robust design methods.
Finally, if the interactions between the flow and acoustic field of the propulsion system with the airframe can be detrimental to aerodynamic performance or noise, they also offer opportunities to explore novel flow and acoustic control strategies, not yet explored in combination with installation effects. ENODISE will implement advanced materials and shape modifications to mitigate the adverse installation effects observed during the first phase of the project. The last objective of this project is thus the inclusion of innovative flow and acoustic control technologies in the optimization loop in order to derive better integration designs with minimal detrimental installation effects.
