Description
本発明は、浮体式風力タービン構造体に関するものである。
−羽根とアームとの間の距離を長くできるので、羽根に作用する繰り返し荷重および機械的疲労を低減できる。
−単一マストの大きな直径に比べて支持アームの直径を小さくすること、および風力タービン構造全体を風に向けることにより可能になる支持アームの空力的形状により、あらゆる風向きを考慮して設定する必要のある固定マストを備え、ナセルのみが風に向かう風力タービンの場合と異なり、一般的なナセルの支持マストによって生成される空力的擾乱を減少させることができるので、羽根に作用する繰り返し荷重および機械的疲労を低減できる。
−ナセルの支持アームを複数本備え、ロータの中空軸内における利用可能な空間を大きくし、前記空間を用いて支持アームの上部連結部の力を分散および拡散させるとともに支持アーム同士を強固に連結することにより、浮体式風力タービン構造体に作用する応力集中を緩和できる。
−従来技術にかかる構造体よりも構造体の固有振動数を増加させることができるので、固有振動数をずらすために構造体のサイズを大きくする必要がなく、ロータによって生じる振動によって共振が生じないように保証できる。
−ロータと羽根との組立構造体の全体の外径が一定である場合、羽根の長さを短くできるので、羽根の自由長を短くし、羽根の根元に作用する機械的応力を低減できる。
Claims (5)

上部にナセル(3)が接続され、下部にフロート(6)が接続された、ナセル(3)を支持するための少なくとも2本の支持アーム(4),(4´)とを備え、
