*†进行了音爆分析，以评估先进超音速商务喷气式飞机预计运营的影响。这些操作是使用雷神公司进行NASA NextGen NRA研究的团队开发的商业案例模型定义的。ACES提供了飞行器的4D预测轨迹，PCBoom 6被用来计算考虑每次超音速操作的地形影响的单次事件音爆暴露。模拟的车辆源特性反映了采用悬臂抑制技术的低悬臂优化车辆。考察了地形对单粒子响度的影响。此外，还提供了美国大陆地区的累积景气影响结果。
*† A Sonic Boom Analysis has been conducted to assess the impact of projected operations by advanced Supersonic Business Jets (SSBJ). The operations were defined using a business case model developed by the Raytheon Team conducting NASA NextGen NRA research. ACES provided the projected 4D trajectories for the vehicle and PCBoom 6 was used to compute single event sonic boom exposure considering terrain effects for each supersonic operation. Vehicle source characteristics modeled are reflective of low-boom optimized vehicles with boom suppression technology. An examination of the effects of terrain on single event loudness is provided. Cumulative boom impact results are also provided for the continental United States.
