Mhd flow control experiment in air: Test article design

none5noAn advanced flow control experiment, concerning magnetohydrodynamics (MHD) interaction over a blunt body, has been designed by Alta, CIRA and Department of Electrical Engineering (DIE) of University of Bologna and to be realized in CIRA's plasma wind tunnel "Scirocco" under a technology research program (TRP) funded by the European Space Agency (ESA). This work is a further step of the researches performed during the last decade by Alta and DIE in the field of MHD interaction. This experimental campaign foresees the employment of a 50 kW electromagnet, enclosed into an insulated blunt-shaped metallic TPS convectively cooled and electrically insulated by a ceramic coating. The test article has been designed for an air flow with nominal stagnation conditions of p0=2 bar and h0=22 MJ/kg, but several other conditions are planned to be investigated. The aim of the experimental campaign, along with a better understanding of the physical phenomena occurring within an highly ionized shock layer with an applied magnetic field, is the comparison of the collected data with the numerical predictions of CFD codes developed by CIRA. © 2011 by the American Institute of Aeronautics and Astronautics, Inc.
