Principles of Magnetohydrodynamical Control of Internal and External Supersonic Flows

This paper demonstrates the possibility of active magnetohydrodynamic (MHD) control supersonic flows containing shock waves. The wave configurations that occur at inlet to a diffuser and in front streamlined semicylindrical model are used for purpose investigation. impact is carried out by organizing local gas discharge regions when applying magnetic field transverse currents. It has been shown changing region application, intensity direction currents, it possible change ponderomotive force acting on flow during MHD interaction. allows locally shape position waves, speed flow, increase or reduction pressure near surface body. experiments were dynamic setup based tube path, capable creating wide range Mach numbers M = 4–7. There was electric pulsed fields with an up 1.5 T. given experimental Schlieren patterns analysis obtained data demonstrate effect on: angle inclination attached shocks, both into decrease; bow approaching body removal from it; aerodynamic drag lift bodies.
