Calculations are performed for a sonic boom generated by two bodies (a disk and a thin body of revolution) in the case of local heating of the incident air flow. The bodies are in a heat trail behind the heating region. The thin body is in an aerodynamic shadow behind the disk. The Mach number of the cold air flow is 2. The calculations are carried out using the combined method of "phantom bodies". It is concluded on the basis of the calculations that the level of a sonic boom can be effectively suppressed by simultaneously using the heating of the incident flow and the aerodynamic shadow behind the disk.
