Gas vortex motion caused by the interaction of microwave discharge and shock layer on the body is the principal mechanism, leading to the body's aerodynamical character istics change. A simplified analysis of gas motion at the beginning of the decay of discontinuity, taking place when the plasmoid contacts the shock layer on the blunted body, is offered. The list of main dimensionless parameters of this motion is discusse d. Energy deposition into the gas during the microwave discharge is evaluated in the experiments. The results of numerical modeling on a basis of Euler equations of a thin limited length low -density channel effect upon supersonic flow past cylindrical AD b ody with complicated cavity are presented. Examination of a possibility to intensify the vortex motion of gas in front of the body with the purpose to manage the latter’s aerodynamic characteristics is presented. Special models, the front surface of which is formed to support gas vortex motion, have been investigated. |
