This paper introduces the study on hypersonic plasma flows associated with planetary entry flights. The study is aiming at improving the prediction accuracy of planetary entry flight environments by investigating the characteristics of hypersonic plasma flows behind shock waves generated in entry flight conditions. In the first part of this paper, one of the ground testing facility to simulate entry flight conditions is described. Then, a measurement technique for hypersonic plasma flows is described by introducing the measurement system developed at the test section of a shock tube. After that, spectroscopic data of CO2-N2 plasma flows in an entry flight condition are shown to describe the thermochemical state in the plasma flows. Finally, the summary of this paper is presented. |
