Description
一方、ガイドベーンに整流機能に加えて構造体機能も持たせる場合には、ガイドベーンにアルミ合金等の金属材料を構成材料として用いる都合上、ストラットを用いる場合と同じく航空機ジェットエンジンの軽量化の妨げになるという問題があり、これを解決することが従来の課題となっている。
さらに、本発明の請求項3に係る翼の連結部構造において、前記翼が前記ジェットエンジンの静翼である構成としている。
図1〜図4は本発明に係る翼の連結部構造の一実施例を示しており、この実施例では、ジェットエンジンを構成する静翼としてのガイドベーンの連結部を例に挙げて説明する。
なお、複数の動翼10の各チップ間には、振動防止及び空力性能改善のためのチップシュラウドが連結されているが、このチップシュラウドは図1において図示していない。
