PROBLEM TO BE SOLVED: To implement optimal design as reducing costs and labors in comparison with a conventional design for a shape of an aircraft in which co-existence of an aerodynamic characteristic and a stealth property is required.SOLUTION: An aircraft design device is configured to: receive a value of a design parameter for a shape of an intake duct; prepare each analysis model for an aerodynamic characteristic analysis and RCS (radar cross section) analysis using the value of the design parameter to calculate an aerodynamic characteristic of the intake duct and RCS characteristic thereof; determine whether an analysis result satisfies a predetermined design condition; update the value of the design parameter when it is determined that the analysis result does not satisfy the design condition; and repeat the update of the design parameter, the analysis of the aerodynamic characteristic and RCS characteristic, and the determination analysis until it is determined that the analysis result satisfies the design condition.SELECTED DRAWING: Figure 2

    【課題】空力特性とステルス性との両立が要求される航空機の形状について、従来に比べてコストや労力を低減させつつ好適に設計を行う。【解決手段】航空機設計装置は、インテークダクトの形状に関する設計パラメータの値の設定を受け付け、設計パラメータの値を用いて空力特性解析及びRCS(レーダー反射断面積)解析用の各解析モデルを作成してインテークダクトの空力特性及びRCS特性を計算し、この解析結果が予め設定された設計条件を満たすか否かを判定し、解析結果が設計条件を満たしていないと判定した場合に、設計パラメータの値を更新し、解析結果が設計条件を満たしていると判定するまで、設計パラメータの更新、空力特性及びRCS特性の解析及び判定処理を繰り返す。【選択図】図2
