摘要:
A system is disclosed including a first blade (102), a second blade (104), and a snubber (100) disposed between a pressure side (106) of the first blade (102) and a suction side (108) of the second blade (104). An inclination angle of a chord line (112) of the snubber (100) may be varied from the pressure side (106) of the first blade (102) to the suction side (108) of the second blade (104) to minimize an incidence angle between a number of streamlines (110) in a not disturbed flow field and the inclination angle of the chord line (112).

터빈의 케이싱과 블레이드 사이의 간극부위에서 연소가스의 주 유동방향과 반대되는 반류 유동의 생성을 위한 블로우 시일의 형성을 통해 연소가스의 누설 손실을 최소화하고 기관의 효율을 향상시킬 수 있는 가스 터빈의 블레이드 팁 실링 장치를 개시한다. 전술한 블레이드 팁 실링 장치는 연소가스의 유동을 안내하는 케이싱(22), 상기 케이싱(22) 내에서 회전축(20)과 결합되는 복수의 블레이드(26), 상기 블레이드(26)의 선단부를 감싸도록 설치되는 슈라우드(28), 상기 슈라우드(28)에 전 둘레를 따라 외주면 상에 복수로 형성되는 블로우 시일(30), 및 상기 블레이드(26)의 회전속도에 따라 상기 블로우 시일(30)의 경사각도를 가변적으로 조절하는 선회설비를 구비한다.
摘要:
A turbine blade tip shroud (22C, 22D) with a seal rail (32C, 32D) oriented in a circumferential direction of rotation (29) relative to a turbine axis, and extending radially outward from the tip relative to the turbine axis. A first tooth (48, 68) and a second tooth (50, 70) form respective downstream and upstream lateral departures or bumps on the seal rail. Each tooth has a sharp top leading edge (48, 50, 68, 70) and a smoothly curved side surface (49, 51, 69, 71). A back portion (56, 76) of the seal rail may span linearly from a lateral peak (66, 78) of the second tooth to a back end (62) of the seal rail that is centered on an extended centerline (60) of a front portion (54, 74) of the seal rail. The teeth may be disposed proximate or over a stacking axis (52) of the blade.
摘要:
The present disclosure provides for a turbine wheel having a blade platform disposed to compliantly secure ceramic turbine blades to a rotatable disk. The platform includes opposing ends to engage a portion of an airfoil of each turbine blade and radial extensions to engage a portion of a root of each turbine blade. A method of making the turbine wheel is provided.
摘要:
A fan platform for a gas turbine engine may include an outer flow path surface extending between a first side and a second side. An inner surface extends between the first side and the second side, and faces radially oppositely the outer flow path surface. A plurality of platform hooks may extend radially inwardly from the inner surface.
