Description
また、構造が簡単なので、小型や中型の風車を安価に製造することができ、管理メンテナンスも容易である。
なお、これらの図の中で、同一部分については同一符合を付す。
前部ブレード3aの外側の翼面の後縁部は後部ブレード3bの前縁部よりも後方に延長されて後方カバー31aとなり、後部ブレード3bの全幅の30〜100%、好ましくは50〜70%がこの後方カバー31aに覆われた状態になっている。なお、後方カバー31aの幅は、所定の風速以上になったとき、後部ブレードの翼端に発生する遠心力が抗力より大きくなるような幅とする。
後部ブレード3bは、無風時又は微風時には、自重により、図1に示した状態となっており、前部ブレード3aの後方カバー31aと後部ブレード3bがなすサボニウス構造の凹部に後方又は斜め方向からの風を受けて微風の状態でも効率よく抗力を発生しブレード支持杆5、ハブ6を介して回転モーメントを鉛直回転軸2に伝達する。

3…………ブレード
3a…………前部ブレード
31a…………後方カバー
3b…………後部ブレード
4…………回動軸
5…………ブレード支持杆
6…………ハブ
