Description
本出願は、2014年5月30日出願の、「Hydroelectric Turbine」という名称の米国特許仮出願第62/005614号、及び、2014年5月30日出願の、「Hydroelectric Turbine, Anchoring Structure, and Related Methods of Assembly」という名称の米国特許仮出願第62/005,681号の優先権を主張するものであり、これらの内容全体は、参照により本明細書に組み入れられる。
図1(A)及び図1(B)をここで参照すると、本開示による水力発電タービン100の例示的な実施形態が示されている。水力発電タービン100は、ステータ106の外側に半径方向に配置されたロータ104を含む。この配置において、1つ又は2つ以上のブレード(ハイドロフォイル)101が、半径方向の内側に及び/又は半径方向の外側に延在することができる。例えば、図1(A)の例示的な実施形態を参照すると、半径方向の内側に延在するブレード部103及び半径方向の外側の延在するブレード部102があり得る。両方のブレード部102、103は、流体の流動(図1(A)では矢印により指定)内に配置され、それによって、ロータ104に、中心軸Y周りにステータ106に対して回転させる。様々な例示的な実施形態(図2を参照されたい)において、複数のブレードをロータ104の周縁部の周りに取り付けることができる。
