 note = {成層圏プラットフォーム飛行船の実現に向けて、推進系に係わる船体-プロペラ系の推進性能とプロペラ特性を本報告で取り上げる。船体-プロペラ系の取り扱いと、多発プロペラの効率をはじめに示した。推進性能解析では、船舶工学の手法と研究開発実績により船体-プロペラ系の相互干渉解析を実施し、船体プロペラ配置形態の推進性能を推算すると共に、プロペラによる船体干渉の様子を示した。プロペラ特性の解析では、成層圏条件で運用するプロペラにおいて、プロペラの製造実績を生かし空力と構造を解析し、プロペラの多発化および軽負荷化を検討した。また、求められる成層圏用の低レイノルズ数プロペラを設計し、その運用について検討した。検討の結果、船尾プロペラによる推進効率の向上が確認された。さらに、設計された低レイノルズ数プロペラにより、成層圏における低回転数の制限が緩和された。また、プロペラの重量軽減が成された。, The propulsion performance and propeller characteristics on hull-propellers system within the propulsion system are taken up in this paper toward the realization of the stratospheric platform airship. First of all, the efficiencies of multi-propellers were studied. Next, the mutual interference analysis of the hull-propellers system was carried out by the method of ship engineering on the propulsion performance. Furthermore, the propulsion performance of the propellers that were arranged to the hull was calculated, and the hull interference by the propellers was shown. In the end, propeller characteristics used at stratosphere were analyzed in the aerodynamics and structure. In addition multi-propellers and light loading propeller were examined. As a result, the low Reynolds number propeller for stratosphere was designed and examined for use. The improvement of the propulsion efficiency by the stern propeller was confirmed as a result of the examination. Furthermore, the relaxation of the low revolutions of propeller in stratosphere was improved by the designed low Reynolds number propeller. Also the weight reduction of this propeller was attained., 資料番号: AA0049490000, レポート番号: JAXA-RR-05-056},
