Effect of Local Heat Supply into Supersonic Incoming Flow Ahead of Thin Body with Disk on Intensity of Weak Far-Field Shock Waves

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%.
