Abstract

This paper discusses the magnetohydrodynamic flow of a supersonic plasma flux around a thin conductive body. The specific features of the inductive interaction of the body with the plasma and the process by which plasma waves are generated when the body rotates are investigated. The structure of the magnetic-field perturbations and the distribution of the plasma currents that result from the inductive interaction are studied. Expressions are obtained for the forces that act on a plate and the torques produced by these forces. A simple model is used to take into account the kinetic effects associated with the finiteness of the absorption and emission currents that transport charge from the plate to the plasma and back. A surface-potential distribution is found that can substantially accelerate particles in the neighborhood of the body.
