Presentation
Abstract
A summary is provided for the First AIAA Sonic Boom Workshop held 11 January 2014 in conjunction with AIAA SciTech 2014. Near-field pressure signatures extracted from computational fluid dynamics solutions are gathered from nineteen participants representing three countries. These submissions are propagated to the ground and noise measures are computed. This allows the grid convergence of a noise measure and a validation metric (difference norm between computed and wind tunnel measured near-field signatures) to be studied for the first time. A statistical analysis is also presented for these measures. The configurations studied are two required configurations and an optional configuration with a more complex geometry and signature. The complex wing-body-tail-nacelle configuration showed a larger variation in the Perceived Level noise measure than the two required cases. Understanding the sources of the variation observed at the workshop is critical to ongoing efforts to further the state-of-the-art in low boom configuration analysis and design through simulation.
