Description
準円における角位置を記述することができる。
ある。但し、実際のタービンには、さらに多くの第1段静翼が順次間隔を置いて周方向に配列されて環状の列を形成している。同様に、さらに多くの第1段動翼が順次間隔を置いて周方向に配列されて環状の列を形成している。図面を簡略化するため、図3ではこれらの追加静翼及び動翼を省略した。また、この略図は縮尺を度外視した説明図である。タービンシステムはまた多くの場合、さらに多くの燃焼器及び移行ダクトを含むが、説明の便宜上、燃焼器72及び移行ダクト74をそれぞれ1つだけ図示した。
料で形成することができる。移行ダクトは衝撃冷却、滲み出し冷却、蒸気冷却またはその他の冷却技術で冷却することができる。
ン・動翼集合体の長手方向軸218に対してほぼ約40°乃至約85°の角度で排気口210からガスを排出するように移行ダクト200を構成する。ガス流はほぼ長手方向及び接線方向によって画定される平面内を流動するように排出口210から放出されるから、ガス流の方向は半径方向成分を殆ど含まない。
Claims (7)
- 長手方向の軸(218)を有するロータ集合体から半径方向に延びる複数の動翼を有する第1段動翼列(126)と、第1段動翼列の長手方向上流に且つ第1段動翼列の半径方向外方に位置する少なくとも1つの燃焼器(220)とを含む軸流燃焼タービンエンジンにおいて燃焼器からのガス流を第1段動翼列に誘導するための移行ダクト(200)であって、
前記移行ダクト(200)は、
吸気口(204) から下流へ延びるほぼ真直ぐの吸気口セクション(202)と、
吸気口(204)からのガス流を方向変換させる湾曲した排ガス・ダイバータセクション(206)と、
排ガス・ダイバータセクション(206)からのガス流を第1段動翼列(126)に向かって放出する排気口(210)と、長手方向の軸(214)とを有するほぼ真直ぐの排気口セクション(208)とを有し、
排気口(210)は吸気口(204)に関してロータ集合体の長手方向、半径方向及び周方向にオフセットしており、
排ガス・ダイバータセクション(206)は下流の排気口セクション(208)の長手方向軸(214)がロータ集合体の長手方向軸(218)と40°乃至85°の角度を成すように湾曲しているため、排気口(210)からのガス流がロータ集合体の長手方向軸(218)に関して40°乃至85°の角度で第1段動翼列(126)に向かって放出されることを特徴とする移行ダクト。 - 排気口(210)はロータ集合体の周方向にほぼ矩形である請求項1に記載の移行ダクト。
- 排気口(210)はロータ集合体の周方向に弓形である請求項1に記載の移行ダクト。
- 吸気口セクション(202)は吸気口(204)におけるほぼ円形の断面から排ガス・ダイバータセクション(206)との交差部におけるほぼ台形の断面に移行する請求項1に記載の移行ダクト。
- 吸気口セクション(202)の内側流路の周方向の幅は吸気口(204)から排ガス・ダイバータセクション(206) との交差部に向かって狭くなる請求項1に記載の移行ダクト。
- 吸気口セクション(202)の内側流路の半径方向の高さは吸気口(204)から排ガス・ダイバータセクション(206) との交差部に向かって低くなる請求項5に記載の移行ダクト。
- 移行ダクト(200)は少なくとも一部がセラミック母材の複合材から成る請求項1に記載の移行ダクト。
