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%.

带盘薄体前方超音速入流的局部供热对弱远场冲击波强度的影响

摘要研究了降低大气中超音速飞行物体产生的冲击波强度的可能性。计算了薄体产生的近场和远场冲击波的参数，薄体前方有一个圆盘，圆盘穿过入射气流，入射气流的马赫数为 2。计算采用 "幻影体 "组合方法进行。计算结果表明，同时使用机体前方的空气动力表面和入射气流加热，可以将远场冲击波的强度降低约 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.
