NASA and industry have made substantial progress in minimizing sonic booms by carefully shaping aircraft to control the shockwaves. But a sonic boom is a complex phenomenon, and what works in steady flight might not work so well at other times. Accelerating and turning can cause the shockwaves to focus, creating an amplified superboom. NASA is conducting flight research to determine if a shaped boom can survive the focusing, or if operating techniques must be developed to ensure a ...
