Abstract
System study of a next generation launch vehicle, which is a partially-resusable vehicle to reduce transportation cost drastically, are being conducted. Aerodynamic chracteristics of the vehicle are numerically studied with various vehicle configurations and flight conditions to find the optimal system design and to progress the overall system design.

Achievements of the Year
Aerodyanmic characteristics of a partially resuable launch vehicle were evaluated. The aerodyamic characteristics are crucialy important in terms of progressing the overall vehicle system design and other sub-system design such as flight control systems, structure systems and propulsion systems since the aerodynamics characteristics are fundamental input data for various analysis.
