This report results from a contract tasking Leninetz Holding Company, NIPGS as follows The contractor will analytically investigate applying magneto hydrodynamic MHD generators to a generic hypersonic inlet. The inlet geometry will be a two-shock inlet with the total turning angle of 15 and designed for Mach 10. The contractor will evaluate the location and configuration of electromagnet coils and electrodes for the MHD system. Flow fields in the MHD controlled inlet will be calculated in 2D Euler approach. Analysis of elementary processes responsible for flow ionization will be assessed. Space distribution for power density deposited in the flow and for conductivity of flow due to e-beam propagation will be calculated, A mathematical model of the MHD-controlled inlet with non-equilibrium MHD generators using e-beams as the ionizer will be developed. Finally, flow fields in the MHD-controlled inlet will be calculated in a wide range of parameters altitude, Mach number contraction ratio, MHD and ionizer parameters. The main characteristics of the inlet will be determined such as the air mass flow-rate flow compression and total pressure recovery. Requirements for the magnetic system and ionizer, which ensure efficient control of inlet at off-design conditions, will be formulated.
