Abstract
Description
‐このシステムのコンパクト性は、最新型ターボファンのハブ比と同一のハブ比でファンが構成されることを可能にする。エンジンの空間要件に増大はなく、したがって抗力および質量に関する不利益はない。
‐従来型ターボファンと同数の羽根を有すること、したがって最新式ファンと同じ出力を有することが可能である。
‐内部気流は円錐状に作り出されることができて、羽根の根元部の空気力学が遠心分離作用から利益を得るようになる。
‐2つのキャップと2つのファンディスクとを用いることで、自然の二重構造によって翼の求心的保持がもたらされる。
‐最後に、万一翼のピッチの制御システム内の圧力が低下した場合にも、遠心力が翼をフェザリングされたポジションに自然にもたらす傾向を有する。
