Focus boom simulation benchmark cases for the 182nd ASA Meeting May 2022

The low-boom prediction committee comprised of several research agencies and companies across the world plans to organize a special session dedicated to prediction and comparison of focused sonic booms. This presentation will document and discuss the benchmark cases that will be studied and compared during this special session. The case description would include the underlying near-field CFD data along with relevant flight conditions and mission trajectory information for the participants to simulate and discuss their individual focus boom predictions. Details of the CFD simulation conditions and solution procedure to obtain off body pressure waveforms on a cylindrical surface around the aircraft at a few selected points along the flight trajectory will be provided. The rationale for the choice(s) of the mission trajectories to result in focus booms near the ground for comparison using multiple independent implementations will be provided as well.
