Abstract
We investigate the influence of the real gas effect on aerodynamic performance and aerodynamic heating for the target lifting body.
Goal
In the chemical reaction model, various temperature models have been proposed. The objective is to investigate the aerodynamic performance of the lifting body and their effect on aerodynamic heating.
Objective
The aim is to analyze the airflow analysis around the target lifter body with different temperature models and to compare the aerodynamic coefficients.

Use of the Supercomputer
It is used for the parametric study of earch high calculation cost case.
Necessity of the Supercomputer
Since the computation cost of the air flow considering the real gas effect around the whole lifting body is high, it is necessary to use the supercomputer.
Achievements of the Year
We analyzed four types of temperature models at altitude of 80 km and Mach number of 21.8 at the different 5 cases of angle attack for the target lifting body.
