Abstract

The level of a sonic boom that occurs in a supersonic air flow around two bodies—a disk and a thin revolving body—is calculated. The bodies are placed one after another. The thin body is in the aerodynamic shadow of the disk. The Mach number of the incident flow is 2. The calculations are performed using the combined body phantom method. By varying the position and size of the disk, it is possible to reduce the level of the sonic boom. Based on the calculation results, the gas-dynamic factors affecting the level of the sonic boom are described.

音速臂对超音速流中身体相对位置的依赖性

摘要

计算了围绕两个物体（一个圆盘和一个细的旋转物体）的超音速气流中发生的音爆的水平。尸体一个接一个地放置。薄体位于磁盘的空气动力学阴影中。入射流的马赫数为2。使用组合体模法执行计算。通过更改磁盘的位置和大小，可以降低音爆臂的高度。基于计算结果，描述了影响声波水平的气体动力学因素。
