Abstract

가변 싸이클 가스 터빈 엔지용 가변 구역 우회 분사기(VABI)는 소음 방지 장치 내부로 경사져 있는 원추면을 구비한 원주 방향 연속 밸브와, 확산기에 부착된 원주 방향으로 분할된 밀봉체 및, 엔진의 외부 도관 외측에 위치한 밸브 작동기를 포함한다. 각각의 밀봉 부품은 원주 방향으로 인접한 부품들 사이의 차등 축 방향 운동을 허용하도록 장전된 스프링이며 폐쇄 위치에 있을 때 밸브를 밀봉 결합시키도록 밸브 원추면을 보충하는 시트부를 가진다. 또한, 밀봉 부품은 낮은 공기 역학적 형상을 갖는 형태이고 밸브가 개방위치에서 VABI 원추면과 협력하여, 우회 흐름이 중심부의 가스 흐름속으로 분사될 때 VABI 밸브 및 중심부 흐름 통로 벽에 부착된 우회 흐름을 유지하는 환상의 원추 채널을 제공한다. 내부 및 외부 크랭크 아암은 작동기로 부터 외부 도관 벽을 통과하는 선형운동을 전달하여 개방 및 폐쇄 밸브 위치 사이의 밸브와 소음 방지 장치를 축 방향으로 이동시키도록 아이들러 아암과 협력한다.
