sBOOM An advanced sonic boom propagation tool

About this technology

Overview

This innovation presents an approach to predict the sonic boom ground signatures accurately by numerically solving the Augmented Burgers' equation. The method is capable of predicting sonic boom signatures with consideration of atmospheric losses to account for the realistic attenuation of the sonic boom waveforms. This software is an enhanced version of the software sBOOM, currently in the software catalog. The updated numerical discretization of the governing equations is fully conservative and duality preserving. As a result of these improvements, there is a significant reduction in the number of points required to convergence of ground loudness metrics. Computation of loudness metrics is performed using digital filters. This improves the loudness calculation particularly at high sampling frequencies. The method is capable of predicting under-track and off-track ground signatures, with or without wind effects, along with consideration for aircraft maneuvers. This method is efficient and accurate, making it a very useful analysis tool in the development of supersonic cruise aircraft.
