          <datacite:description descriptionType="Abstract">空力設計法を、3次元非構造オイラーコードと離散アプローチの随伴コードを用いて開発してきた。得られた随伴コードは、翼・機体・ナセル形状の超音速輸送機の翼設計問題に適用される。Hicks-Henne形状関数を表面幾何学形状の摂動に用い、設計過程において楕円方程式法を内部格子の修正に用いた。ナセルの平行移動に伴う設計パラメータを除いて、内部格子の感度は無視した。逐次2次プログラミング法を揚力や翼厚に対する拘束を保持しながら抗力を最小にすることに用いた。良好な設計結果は、この設計方法の正当性と有効性を確認した。</datacite:description>
          <datacite:description descriptionType="Other">An aerodynamic design method has been developed by using a three-dimensional unstructured Euler code and an adjoint code with a discrete approach. The resulting adjoint code is applied to a wing design problem of supersonic transport with a wing-body-nacelle configuration. Hicks-Henne shape functions are adopted for the surface geometry perturbation, and the elliptic equation method is employed for the interior grid modification during the design process. Interior grid sensitivities are neglected except those for design parameters associated with nacelle translation. The sequential quadratic programming method is used to minimize the drag with constraints on the lift and airfoil thickness. Successful design results confirm validity and efficiency of the present design method.</datacite:description>
