Description

터어보 장치의 단독 블레이드를 위한 감쇠부재
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 로우터의 부분적인 발췌부에 대한 유동방향에서의 도면.
제2도는 감쇠부재에 대한 제1구현에 형상의 부분단면도.
제3도 내지 5도는 감쇠부재의 다양한 체결변형예를 나타내는 도면.
*도면의 주요 부분에 대한 부호의 설명
(1):로우터, (2):블레이드, (2'):흡입측, (2"):압력측, (3)(3'):평판, (4a)(4b)(4c):지지면, (5)(6)(7)(8):보유형성부.

Claims (5)

  1. 로우터(1)에 고정된 블레이드(2)가 가급적이면 방사상으로 외부 영역에 서로 함께 접속되며, 2블레이드 간의 접속은 로우터의 중심을 향해 구부러진 탄성변형성 평판(3,3')으로 이루어지며, 이 평판은 1쪽 블레이드의 흡입측(2') 및 제2의 인근 블레이드의 압력측 상의 보유형성부(5,6,7,8)에 계합되는 것을 특징으로 하는 터어보 장치의 단독 블레이드를 위한 감쇠부재.
  2. 제1항에 있어서, 평판(3)이 2중 곡부를 가짐을 특징으로 하는 감쇠부재.
  3. 제1항에 있어서, 평판(3)이 타원체로서 2원형 지지면(4)을 가짐을 특징으로 하는 감쇠부재.
  4. 제1항에 있어서, 평판(3)이 본질적으로 3개의 지지면(4a,4b,4c)을 갖춘 3각형 형상으로써, 이중 1지지면(4a)은 블레이드의 흡입측(2')에, 그리고 나머지 2지지면(4b,4c)은 압력측(2″)에 계합됨을 특징으로 하는 감쇠부재.
  5. 제4항에 있어서, 터어보 장치의 축방향으로 보았을 때 블레이드 흡입측(2')의 지지면(4a)이 압력측(2″)의 2지지면(4b,4c) 사이에 위치함을 특징으로 하는 감쇠부재.
    ※ 참고사항:최초출원 내용에 의하여 공개하는 것임.
