Abstract
Kyushu Institute of Technology has been studying a fully reusable space transportation system using winged rocket called WIRES (WInged REusable Sounding rocket). One of the objectives of this project is to design optimized airfoil of the winged rocket using evolutionary algorithms associated with computational fluid dynamics.

Reasons for using JSS2
An enormous number of airfoils should be evaluated for optimization. It will be a nontrivial problem for a workstation at our resource. Therefore, calculation cost reduction using JSS2 is desired.
Achievements of the Year
In this fiscal year, we planned to describe the optimization algorithm and carry out the multi-objective optimization for airfoils using JSS2 which can maintain the high angles of attack at re-entry phase and have a good lift-to-drag ratio. However, due to the delay in development, we only made calculations using a small scale workstations.
