Abstract
The possibility of reducing the intensity of shock waves from a body going supersonic in the atmosphere was investigated. Parameters of near- and far-field shock waves from a thin body with a disk located ahead of the body across the incoming flow at local heating of the incoming flow were calculated. The Mach number of the incoming cold air flow was 2. The calculations were performed by the combined “phantom body” method. The calculation results show that simultaneous use of an aerodynamic surface ahead of the body and heating of the incoming flow makes it possible to reduce the intensity of far-field shock waves by approximately 30%.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
