Abstract:
The potentialities of MHD effect for flow control in a scramjet inlet are discussed. In the papers it is shown that the MHD interaction allows one to control the oblique shocks position and to make the flow field in the inlet at off-design conditions quite similar to one at design conditions in the case when the flight Mach number is greater than the design Mach number. This effect is achieved at various configurations of the magnetic field and the area of the MHD interaction. In the papers it is shown that the MHD control allows one to increase both the air capture and the flow compression in the inlet at flight Mach number. According to one paper this AWC/SSI effect is observed not for all configurations of the magnetic field, but only for the case when the vector of magnetic flux density has a negative projection on the direction of an incident flow. In the present paper the significance of such characteristics as the magnetic field orientation, the power spent on the flow ionization and geometric proportions of the ionized region in the MHD control by the scramjet inlet will be analyzed.
