• Note (General): 航空宇宙技術研究所 7-9 Jun. 2000 東京 日本; National Aerospace Laboratory 7-9 Jun. 2000 Tokyo Japan; 超音速逆問題の定式化過程で現れるいくつかの非固有積分を取り扱う方策を論じた。積分方程式のなかに表わされた逆問題を使用して、残差補正概念に基づいた設計方法が開発し、日本のSST実験機主翼の空力設計に応用した。この定式化の過程で積分上に特異点が現れ、その数学的取り扱いに困難が生じた。この困難を、HadamardとCauchyの積分定理を拡張することによって克服し、逆問題空力設計上の数学的整合性を保証することが出来た。; Strategies to treat several improper integrals which appear during the formation process of a supersonic inverse problem are discussed. Using the inverse problem formulated into integral equations, a design method based on the residual correction concept has been developed and applied to the aerodynamic design of wings for a Japanese SST experimental model. During the process of the formulation, mathematical difficulties have been encountered in dealing with the improper integrals, that were suffered by singularities. These difficulties have been settled using the extended idea of Hadamard and Cauchy's concepts of integrals. Thus, the mathematical consistency of the inverse design method has been guaranteed.; 資料番号: AA0028635051; レポート番号: NAL SP-46
