境界要素法を活用した航空機概念設計法について

—大学における設計教育への適用—

Aircraft conceptual design method currently used for the university design education mainly utilises empirical values based on the statistical database to determine the main design parameters. Therefore, it is often difficult for students to understand the effects of aerodynamic parameters such as a wing aspect ratio and a taper ratio during the design process. In this paper, a conceptual design method that incorporates a boundary element method is discussed so that aerodynamic characteristic estimations are possible and that the students can easily comprehend the effects of aerodynamic parameters while designing the airplane. A single engine light airplane has been designed by the present conceptual design method. The results obtained by the present method and those by the conventional method are compared and discussed.
