Abstract
Description
상기 브래킷을 구비하는 압력면 부분은 블레이드 몸체의 압력면 상의 두 지점 사이에 거리를 두고 형성되어 있는데, 제 1 지점은 선두 에지 영역에 배치되며, 제 2 지점은 후단 에지 영역에 배치되고, 가상의 현은 상기 두 지점을 지난다. 상기 제 1 지점과 브래킷의 사이 및 상기 제 2 지점과 상기 브래킷의 사이에, 블레이드 몸체의 대응하는 영역에서의 블레이드 두께 d1 및 d2 와 대략적으로 같은 거리 a1 및 a2 를 형성하는 것이 특히 유리한 것으로 판명되었다.
Claims (6)
- 선단 에지 (5), 후단 에지 (6), 블레이드 팁 (9), 흡입면 (7), 및 압력면 (8) 이 제공된 블레이드 몸체 (4) 를 구비하는 터빈 블레이드로서, 블레이드 팁 (9) 의 영역의 블레이드 몸체 (4) 의 일면 상에 브래킷 (10) 이 위치하며, 상기 브레킷은 선단 에지 (5) 및 후단 에지 (6) 사이에서 거리를 두고 있는 표면의 영역 (11) 에 신장하는 터빈 블레이드에 있어서,상기 브래킷 (10) 은 상기 블레이드 몸체 (4) 의 압력면 (8) 의 표면영역 (13) 에 배치되고, 선단 에지 (5) 와 브래킷 (10) 사이의 거리 (a1) 및 후단 에지 (6) 와 브래킷 (10) 사이의 거리 (a2) 는 가상의 현 (12) 을 이용하여 한정되며, 이 가상의 현 (12) 은 선단 에지 (5) 영역에서 블레이드 몸체 (4) 의 압력면 (8) 의 제 1 지점 (14) 과 후단 에지 (6) 영역에서 블레이드 몸체 (4) 의 압력면 (8) 의 제 2 지점 (15) 을 지나고, 거리 (a1 및 a2) 는 각각 제 1 지점 (14) 과 브래킷 (10) 의 사이 및 제 2 지점 (15) 과 상기 브래킷의 사이에 형성되며, 이들 거리 (a1 및 a2) 는 블레이드 몸체 (4) 의 대응하는 영역에서의 블레이드 두께 (d1 및 d2) 와 같은 것을 특징으로 하는 터빈 블레이드.
- 제 1 항에 있어서, 선단 에지 (5) 로부터 블레이드 몸체 (4) 의 현 길이 (l) 의 30 내지 40 % 인 곳에서 상기 브래킷 (10) 은 압력면 (8) 위로 최대높이 (hmax) 를 가지며, 상기 브래킷 (10) 의 높이는 블레이드 몸체 (4) 의 선단 에지 (5) 및 후단 에지 (6) 의 방향으로 연속적으로 감소하는 것을 특징으로 하는 터빈 블레이드.
- 제 2 항에 있어서, 상기 브래킷 (10) 의 최대높이 (hmax) 는, 블레이드 팁 (9) 으로부터 먼 쪽에서 브래킷 (10) 에 인접한 블레이드 몸체 (4) 의 일영역에서의 블레이드 두께 (d3) 와 같은 것을 특징으로 하는 터빈 블레이드.
- 제 3 항에 있어서, 상기 브래킷 (10) 은 파형인 것을 특징으로 하는 터빈 블레이드.
