    • A gas turbine engine (10) having a turbine blade tip clearance control system (12) for increasing the efficiency of the engine (10) by reducing the gap (14) between turbine blade tips (16) and radially outward ring segments (18) is disclosed. The turbine blade tip clearance control system (12) may include one or more clearance control bands (20) positioned radially outward of inner surfaces (22) of ring segments (18) and bearing against at least one outer surface (24) of the ring segments (18) to limit radial movement of the ring segments (18). During operation, the clearance control band (20) limits radial movement of the ring segments (18), and the turbine blade tips (16) do not have a pinch point during start-up transient conditions. In addition, the smallest gap (14) during turbine engine operation may be found at steady state operation of the gas turbine engine (10). Thus, the clearance control system (12) can set the gap (14) between turbine blade tips (16) and ring segments (18) to be zero at steady state operation.
    • 一种燃气涡轮发动机(10),具有通过减小涡轮叶片尖端(16)和径向外环段(18)之间的间隙(14)来增加发动机(10)的效率的涡轮叶片尖端间隙控制系统(12) 被披露。 涡轮机叶片顶端间隙控制系统(12)可以包括一个或多个间隙控制带(20),所述一个或多个间隙控制带(20)定位在环形段(18)的内表面(22)的径向外侧并抵靠环的至少一个外表面(24) (18),以限制环形部分(18)的径向运动。 在操作期间,间隙控制带(20)限制环段(18)的径向运动,并且涡轮叶片尖端(16)在启动瞬态条件期间不具有夹点。 另外,在涡轮发动机运行期间的最小间隙(14)可以在燃气涡轮发动机(10)的稳态运行中找到。 因此,间隙控制系统(12)可以在稳态运行时将涡轮机叶片尖端(16)和环形部分(18)之间的间隙(14)设定为零。

    • The present disclosure concerns three different types of control rings with adapted thermal response for gas turbines. A first control ring (101) for use in a gas turbine engine (20) includes a control ring segment (107) defining a centerline axis. The control ring segment includes an inner diameter surface (111) and an outer diameter surface (113). A thermally isolating contact (115) is operatively connected to at least one of the inner diameter surface and the outer diameter surface. The thermally isolating contact has lower thermal conductivity than the control ring. Furthermore, another control ring for use in a gas turbine engine comprises a control ring segment defining a centerline axis, wherein the control ring segment includes an inner diameter surface and an outer diameter surface, and an internal cavity defined between the inner and outer diameter surfaces, wherein the internal cavity is configured to contain a material having a higher heat capacitance than the control ring. An even further control ring for use in a gas turbine engine comprises a plurality of radially stacked rings, wherein each radially stacked ring includes a plurality of arcuate segments.
    • 本公开涉及三种不同类型的对燃气轮机具有适应的热响应的控制环。 用于燃气涡轮发动机(20)的第一控制环(101)包括限定中心线轴线的控制环段(107)。 控制环段包括内径表面(111)和外径表面(113)。 隔热接触件(115)可操作地连接到内径表面和外径表面中的至少一个。 隔热接触件的热导率低于控制环。 此外,用于燃气涡轮发动机的另一控制环包括限定中心线轴线的控制环段,其中控制环段包括内径表面和外径表面以及限定在内径表面和外径表面之间的内腔 其中,所述内腔构造成容纳具有比所述控制环更高的热容量的材料。 用于燃气涡轮发动机的更进一步的控制环包括多个径向堆叠的环,其中每个径向堆叠的环包括多个弧形段。
