1203 Study on the nose shape of suborbital spacecraft with whole shape numerical computation

Abstract

Suborbital spacecraft which can reach an altitude of 100km has been studied in JAXA. Suborbital spacecraft is a vehicle proposed for the research and experience under microgravity condition. Suborbital spacecraft has been studied with a baseline shape. In this study, aerodynamic characteristics of the baseline shape was evaluated using numerical simulation. As a result, the shape of the baseline head part generated a strong shock wave. A modified shape with area rule is applied to the head part. Lift and drag were improved with the modified shape.
