Taking such process, it takes much time because many design parameters must be taken into consideration. On the other hand, improvement in the numerical algorithms and the computer hardware has made it possible to design an optimized configuration automatically. Then, applying the numerical optimization method, the wing twist distribution of SST wing-nacelle configuration was determined under the condition of maximizing the lift to drag ratio with a constant lift coefficient. In order to improve the lift to drag ratio it is important to reduce the drag due to the wing-nacelle interference. The aircraft with a cranked arrow wing and two nacelles that have two-dimensional intakes was analyzed. Initial wing twist was 0 deg. Surface pressure distributions were compared between initial configuration and the optimized one. In the optimized one, the interference between the lower surface and the nacelle was reduced, and the drag coefficient of the optimized one is lower than that of the initial one. The same results were obtained for three optimization methods of sequential quadratic programming method, modified feasible directions algorithm, and genetic algorithm.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
