Electron Number Density Measurements in a Saturn Entry Condition

What is it about?

Chemically reacting shock layers involved in the proposed entries into Saturn, Uranus, and Neptune are required to be well-modeled numerically for a better understanding of the aerodynamic heating for the heat shields design. This study is the first time that the electron number density profile has been measured in a scaled blunt-body Saturn entry test. This has produced a unique dataset including electron number density and radiation measurements for numerical model validation. Furthermore, an updated and verified chemical reaction model for relevant non-equilibrium shock layer simulations was also produced.
