Abstract

The planetary atmospheric entry vehicles suffer from severe aerodynamic heating and it was proposed that magnetic field can be used to mitigate the heat-flux to the surface of such vehicles. In this work, experiments are carried out in a free-piston driven hypersonic shock tunnel at a total enthalpy flow of ~6 MJ/kg to investigate the effect of applied magnetic field on the heat-flux to the rectangular block test model. The magnetic field is applied using Neodymium-Iron-Boron permanent magnet. Platinum-based thin film gauges, Large carbon clusters-based thin film gauges and K-type co-axial thermocouples are the three different type of sensors, used to measure the heat-flux to the test model. The performance, capabilities and limitations of each type of sensors in the presence and absence of magnetic field are discussed in this paper. © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA.
