Abstract
Description
(1)ブレードパネル組立体(108)は、ロータが回転するたびにその角度位置に応じて動的に自軸上で回転し、前方抗力と揚力を最適化するとともに、後方抗力を減少させる。
(2)ブレードパネル組立体(108)のピボット可能なサブブレードパネル(1086)は、風との接触面積を変えるためにピボット(開閉)でき、余分な風がパネル組立体を通過し、高速風時の損傷を防ぐことができる。
- 風は、先行技術の設計では軸方向であったのに対し、メインロータの回転に対して接線方向で吹いている。
- ロータの推力は、先行技術の設計における揚力と比較して、抗力(その大部分)によって生成される。
- 抗力と揚力は、先行技術の設計では抗力が直角であったのに対し、回転方向で付加される。
- 同じ出力を得るためにブレードで掃引される面積は、先行技術の設計と比較してはるかに小さい。
- タワーにかかる総推力と出力との比が、発明されたプロセスにおいてはるかに良好である。
- ブレードパネル組立体は、先行技術設計の単一ブレードと比較して、多くのサブブレードパネルで構成されている。
- 風速が一定であっても、各ブレードの絶対角度は一回転で270度以上変化する。
- 風車パネルの製作、設置、運搬が容易である。
- 本発明の一次制御機構及び二次制御機構のいずれか一方又は両方が、本発明を機能させ、より高い出力を達成することが可能である。
1.掃引面積1平方メートルあたりの超高エネルギー出力。
2.軽量なタービン設計。
3.現場での加工・組立が容易
4.超高出力大型タービンでも扱いやすい寸法の部品を採用。
5.小型部品の採用により、困難な現場への資材運搬が容易。
6.メンテナンスに特別なインフラを必要としない。
7.低風速(5km/h以下でも)でも効率よく発電できる。
8.200km/h以上の風速でも発電が可能であり、システムの損傷や発電の中断がない。
9.サイクロン的な風速に対して、発電を停止することなく保護する機能を内蔵している。
10.安全ブレーキ機構が不要。
11.縦型ロータのため、回転エネルギーが地面に伝わりやすい。
12.エネルギーハーベスティングは、縦型ロータの設計において、多目的に使用できる。
