- 出版タイプ： VoR航空由来CO2 排出量の削減を目的に，JAXA では航空機用推進系の電動ハイブリッド化検討を進めている．本報では，その中で発案されたWAT(Wake Adapted Thruster)コンセプト及びその設計方針を示すと共に，WAT・BLI(Boundary Layer Ingestion)を含む空力-推進系干渉効果の強い形態を持つ航空機の燃費性能解析手法を，過去の手法を修正する形で構築した．併せて，燃費性能ベンチマーク対象となる参照機，及びそれを基にした電動ハイブリッド航空機システムのベースライン構成を検討した．その後，改善された燃費性能解析において利用される空力モデル及び推進モデルをベースライン構成に基づいて構築し，試解析を実施すると共に，電動コンポーネントの性能が全機燃費性能に与える影響を評価した．JAXA is currently studying electric hybrid propulsion systems for aircraft with the aim of reducing aviationrelated CO2 emissions. This paper presents the WAT (Wake Adapted Thruster) concept and its design principles that were proposed in the study. It also develops a method for analyzing the fuel efficiency performance of aircraft with configurations that have strong aerodynamic-propulsion interference effects, including WAT and BLI (Boundary Layer Ingestion), by modifying past methods. In addition, a reference aircraft to be used as a benchmark for fuel efficiency performance and a baseline configuration of the electric hybrid aircraft system based on it were considered. After that, aerodynamic and propulsion models to be used in improved fuel efficiency analysis were constructed based on the baseline configuration, and trial analyses were conducted, while the impact of electric component performance on the overall aircraft fuel efficiency was evaluated.形態: カラー図版ありPhysical characteristics: Original contains color illustrationsレポート番号: JAXA-RM-25-003
