タイトル(掲載誌)航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-3
一般注記This is an intermediate summary report on the numerical investigation of subsonic unsteady lifting surface, made by our group in Nagoya University Aeronautical Department. Our interest has been concentrated on simple planar cases because this enables us to investigate the condition economically and thoroughly and thus maximize convergence and accuracy. We, however, believe that most of the results thus obtained would be fundamentally useful even for more complicated problems, such as non-planar wings or wings with finite thickness. The results are divided into the following three main parts: 1) Introduction of error-index parameters E, and development of an adaptive numerical method for lifting surfaces 2) Improvement of numerical calculation of the subsonic kernerl function. 3) Development of new, accurate, fast-converging numerical methods for lifting surfaces. For two-dimensional airfoils a "DLM-C" method has been developed. For finite span wings a finite aerodynamic element method ("DSM-CLS") and two pressure mode methods ("NAM", "NAS") have been developed.
