The Third Sonic Boom Prediction Workshop was held on January 4–5, 2020, in conjunction with the AIAA SciTech conference. The workshop had 23 participants who represented 6 different countries and 18 unique organizations that included government, industry, and academia. The workshop was attended by over 50 individuals. The motivation for the workshop stems from the goal of obtaining supersonic commercial overland flight. To replace the current prohibition with a certification standard, an international effort is required to quantify the accuracy and reliability of prediction methods. The workshops also identify deficiencies in existing methods where further research should be focused. The workshop consisted of two days: the first day focused on near-field computational fluid dynamics and the second day on propagation techniques. For the atmospheric propagation portion of the workshop, two required cases and one optional case were prescribed for the participants to exercise their propagation implementations. This paper presents and discusses the results that were obtained using the sonic boom propagation code sBOOM. Results show that sonic boom carpets could be much different under arbitrary atmospheric conditions as opposed to standard atmospheric conditions. Additionally, several unique features when using sBOOM are presented.

第三届音爆预测研讨会于 2020 年 1 月 4 日至 5 日与 AIAA SciTech 会议一起举行。研讨会有 23 名参与者，他们代表 6 个不同的国家和 18 个独特的组织，包括政府、行业和学术界。50多人参加了研讨会。研讨会的动机源于获得超音速商业陆上飞行的目标。为了用认证标准取代当前的禁令，需要国际努力来量化预测方法的准确性和可靠性。研讨会还确定了现有方法中应重点关注的不足之处。研讨会为期两天：第一天侧重于近场计算流体动力学，第二天侧重于传播技术。对于研讨会的大气传播部分，规定了两个必需的案例和一个可选的案例，供参与者练习他们的传播实施。本文介绍并讨论了使用音爆传播代码 sBOOM 获得的结果。结果表明，与标准大气条件相比，音爆地毯在任意大气条件下可能会有很大不同。此外，还介绍了使用 sBOOM 时的几个独特功能。结果表明，与标准大气条件相比，音爆地毯在任意大气条件下可能会有很大不同。此外，还介绍了使用 sBOOM 时的几个独特功能。结果表明，与标准大气条件相比，音爆地毯在任意大气条件下可能会有很大不同。此外，还介绍了使用 sBOOM 时的几个独特功能。
