Comparison between simplified approach and CFD & propagation tool for sonic boom estimation

The following paper compares results obtained through a simplifying methodology that can be used at the conceptual design phase with results obtained through CFD and then propagation code for ground signature. The application of state-of-the-art models for future supersonic aircraft is discussed within the paper and solutions to overcome these limitations will be presented. Validation using CFD techniques and propagation tools is necessary to accurately define which design and flight condition characteristics most affect noise generation and propagation, as well as to integrate and improve existing methods in the literature with new formulations to estimate sonic boom at an early stage of design. The following workflow was validated for an aircraft with a Concorde-like configuration within the EU-funded MORE&LESS project.
