Abstract
A numerical study of the dynamics of far-field shock waves from a slender body of revolution with a disk has been carried out. The disk is placed in front of the body at an angle to the freestream airflow. The possibility of reducing the intensity of far-field shock waves is demonstrated. An increase in the freestream velocity reduces the range of disk inclination angles over which a decrease in shock waves intensity can be achieved.
