The objectives of optimization are maximization of lift coefficient and minimization of drag coefficient at the angle of attack of 3 degrees. Reynolds number is carefully set to 2.3×10(exp 4), which is the cruising condition of the aircraft. The present computation is utilized supercomputers FX-1 in Institute of Space and Aeronautical Science (ISAS) / Japan Aerospace Exploration Agency (JAXA). The results show that two types of airfoil excel in aerodynamic performance. One airfoil with two large cambers which generate separation bubbles at upper surface has large lift coefficient. The other one with a strong camber in the front of under surface has small drag coefficient and fairy large lift coefficient. Most airfoils on Pareto front have thin thickness under 10% of cord. The present optimization indicates the first step of multi-objective design optimization for practical airfoil design for Mars exploration aircraft, 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0062070031, レポート番号: JAXA-SP-13-001E}, pages = {361--365}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Multi-objective Optimization of Airfoil of Mars Exploration Aircraft using Evolutionary Algorithm}, volume = {JAXA-SP-13-001E}, year = {2013} }
