Description
図3は、図1に示す3枚翼2段型の風車Wの静止トルクをロータ方位角に対してあらわしたグラフであり、併せて平均静止トルクも示している。図3に示すように、図1に示す風車Wの静止トルクは、図8に示す従来の6枚翼1段型の風車W2の静止トルクと同様に平滑化されている。したがって、実施の形態に係る風車Wは、風向の変動の影響を受けにくい。また、実施の形態に係る風車Wの平均静止トルクは0.090Nmであり、図6に示す従来の3枚翼1段型の風車W1の平均静止トルク(0.084Nm)より大きい。したがって、実施の形態に係る風車Wの起動性は良好であるといえる。
(計算条件)
翼枚数:3枚
ロータ半径:0.4m
高さ:1.25m
受風面積:1m2
翼弦長:0.24m
ソリディティ:1.8(翼枚数×翼弦長/ロータ半径)
Claims (2)
- 回転軸に取り付けられた直線翼を有するロータが、回転軸の伸びる方向に複数段配置され、直線翼の回転軸円周方向の取り付け位置がロータ毎に互いに異なっている直線翼垂直軸風車において、
各ロータの直線翼が1つの共通な回転軸に取り付けられ、
回転軸の伸びる方向に隣り合うロータ同士が、両ロータ間に位置し一方のロータの直線翼と他方のロータの直線翼とを連結するリング状端板によって一体化され、
リング状端板の径方向の幅が、各直線翼のリング状端板径方向の寸法よりやや大きいことを特徴とする直線翼垂直軸風車。 - 回転軸の伸びる方向にみて、両端に位置する各ロータの直線翼の終端側の翼端に、それぞれリング状端板が取り付けられていることを特徴とする、請求項1に記載の直線翼垂直軸風車。
