Lecture Title: Progress and Applications of ARI_Boom Software for Sonic Boom Prediction

Lecture Summary/Abstract:

In order to fully consider the impact of real atmospheric environment and improve prediction accuracy of the sonic boom during the design of civil supersonic aircraft，the prediction tool ARI_Boom was developed in ARI based on the hybrid near/far field numerical simulation technology. ARI_Boom includes near-field CFD numerical simulation, real atmospheric model, ray tracing, far-field propagation, superboom prediction, ground sensitivity assessment and other modules. The basic principles, numerical methods and verification of each module are briefly introduced. Specially the effects of atmosphere on the sonic boom propagation characteristics are simulated based on the waveform parameter method, Augmented Burgers equation, multi-dimensional KZK model respectively. Finally, the near future development direction of ARI_Boom has been discussed.
