Reducing the Sonic Boom Level by Heating the Oncoming Airflow

We present the results of calculations of the level of sonic boom in the presence of local heating of the airflow in front of a slender body during its supersonic flight in thermal wake behind the heated regions. The Mach number of a cold oncoming airflow was M = 2. Calculations were performed using a combined method of “phantom bodies.” It is established that sequential local heating of the oncoming airflow in two regions in front of the flying body can reduce the sonic boom level by more than 30% as compared to that in the cold airflow.
