Claims (6)
- マルチローター航空機であって、前記航空機は、
少なくとも5本のアームを有するフレームと、
前記フレームの各アーム上に構成される二重反転同軸ローター/プロペラーの対と、
前記航空機の安定性を維持するために、前記二重反転同軸ローター/プロペラーの対のスロットルを制御するように構成される自動操縦を組み込む制御システムと、
を備え、
いずれか1本のアームの故障の場合に、依然として機能している隣接する二重反転同軸ローター/プロペラーを結ぶ線により形成される多角形の中に前記航空機の重心が依然としてあるような構成の多角形を、前記隣接する二重反転同軸ローター/プロペラーを結ぶ線が画成するように、前記二重反転同軸ローター/プロペラーの対は構成され、
前記二重反転同軸ローター/プロペラーの対のローター/プロペラーのいずれか一つの故障の場合に、前記自動操縦が、ヨー安定性を維持するために、前記対の対応する二重反転同軸ローター/プロペラーを止め、それによって、前記二重反転同軸ローター/プロペラーの対応する対を機能しないようにするように、前記制御システムは構成される、航空機。 - 前記隣接する二重反転同軸ローター/プロペラーを結ぶ線が、前記多角形の中心の近くに前記航空機の重心がある正多角形を画成するように、前記二重反転同軸ローター/プロペラーの対は構成される、請求項1に記載の航空機。
- 前記隣接する二重反転同軸ローター/プロペラーを結ぶ線が、不規則な凸面多角形を画成するように、前記二重反転同軸ローター/プロペラーの対は構成される、請求項1に記載の航空機。
- 前記ローター/プロペラーのいずれか一つの故障の場合に、前記自動操縦はまた、前記航空機の傾斜およびリフト安定性を維持するために、機能しないアームと関連してそれらの位置に応じて、二重反転同軸ローター/プロペラーの機能する対の速度を上げるかまたは落とす、請求項1に記載の航空機。
- 前記ローター/プロペラーのいずれか一つの故障の場合に、前記自動操縦は、二重反転同軸ローター/プロペラーの個々の対の揚力の合計が前記航空機の重量に等しいように、前記二重反転同軸ローター/プロペラーの機能する対の速度を上げるかまたは落とすことによってリフト安定性を維持する、請求項4に記載の航空機。
- 前記ローター/プロペラーのいずれか一つの故障の場合に、前記自動操縦は、リフトの中心を移動してそれを前記航空機の重心と一致させるように、前記二重反転同軸ローター/プロペラーの機能する対の速度を上げるかまたは落とすことによってリフト安定性を維持する、請求項4に記載の航空機。
