    • An expansion joint for connecting first and second fluid-carrying pipes comprising first and second annular couplings which are operably affixable to respective ones of the pipes. In a preferred embodiment the couplings include cylindrical bores of substantially the same diameter disposed relative to one another to form a passage for providing flow communication between the pipes. An annular bellows extends between the couplings for accommodating relative axial movement and angular misalignment between the pipes and is disposed radially outward of the passage to capture any fluid leaking between the interfacing surfaces of the couplings. A second cylindrical bore of a first one of the couplings engages an outer spherical surface of the second coupling to allow the second coupling to pivot in a manner which accommodates angular misalignment between the pipes. Means are provided for limiting the pivoting of the second coupling and for preventing the first coupling from rotating about a centerline of the joint, thereby avoiding unacceptable bending and torsional loading of the bellows. The expansion joint further includes means for limiting the axial compression and axial extension of the bellows.
    • 一种用于连接第一和第二流体输送管的膨胀接头,包括第一和第二环形联接器,其可操作地固定在相应的管道中。 在优选实施例中,联接器包括相对于彼此设置的基本上相同直径的圆柱形孔,以形成用于在管之间提供流动连通的通道。 环形波纹管在耦合器之间延伸,用于容纳管道之间的相对轴向运动和角度偏移,并且设置在通道的径向外侧,以捕获在联接器的接口表面之间泄漏的任何流体。 联接器中的第一联接器的第二圆柱形孔接合第二联接器的外球面,以允许第二联接器以容纳管之间的角度偏移的方式枢转。 提供了用于限制第二联接器的枢转并且用于防止第一联接件围绕接头的中心线旋转的装置,从而避免波纹管的不可接受的弯曲和扭转负载。 膨胀接头还包括用于限制波纹管的轴向压缩和轴向延伸的装置。

    • Blade pitch varying means for use in a gas turbine engine are disclosed. The blade pitch varying means may be used on an engine with a single row or two counterrotating rows of variable pitch blades which are disposed outwardly from an annular gas flowpath and which are connected with a rotating airfoil within the flowpath. The blade pitch varying means comprise actuation means, bearing means, and gearing means. The actuation means are in a nonrotating reference frame disposed inwardly from the flowpath and deliver an axial force. The bearing means transmit the axial force from the nonrotating into a rotating reference frame which contains both the propulsor blade and the airfoil in the gas flowpath. The gearing means are located in the rotating reference frame and convert the axial force into a force for varying the blade pitch.
    • 公开了一种用于燃气涡轮发动机的叶片间距变化装置。 叶片桨距变化装置可以用于具有单排或两排可变桨距叶片的发动机,该排或两个可逆桨叶叶片从环形气体流路向外设置并且与流路内的旋转翼型件连接。 叶片间距变化装置包括致动装置,轴承装置和传动装置。 致动装置位于从流动路径向内设置并提供轴向力的非旋转基准框架中。 轴承装置将来自非旋转的轴向力传递到在气体流动路径中包含推进器叶片和翼型的旋转参考框架。 传动装置位于旋转的参考系中,并将轴向力转换成用于改变叶片间距的力。

    • A combustion chamber for use in gas turbine engines is provided with a liner formed of a high temperature material. The liner includes a plurality of panels of material mounted by means of a slideable, frictional mounting arrangement upon a high strength structural frame. As a result of this mounting arrangement, the liner is substantially isolated from structural forces associated with the combustion chamber, while the frame is substantially isolated from thermal stresses associated with the liner. Means are provided for positioning and securing individual panel members axially relative to the frame. The panels may be continuous annular bodies, or may be circumferentially segmented. In the latter case, means are provided for mounting individual panels in a slideable, frictional cooperation with laterally adjacent panels, as well as for sealing the abutting junctions. The individual liner panels may be easily removed for repair or replacement without disassembling the frame and associated components.
    • 用于燃气涡轮发动机的燃烧室设置有由高温材料形成的衬套。 衬套包括通过可滑动的摩擦安装装置安装在高强度结构框架上的多个材料面板。 作为这种安装结构的结果,衬套基本上与与燃烧室相关联的结构力隔离,而框架基本上与衬套相关联的热应力隔离。 提供了用于相对于框架轴向地定位和固定单个面板构件的装置。 面板可以是连续的环形体,或者可以是圆周分段的。 在后一种情况下,提供了用于将单独的面板安装在与横向相邻的面板可滑动,摩擦协作以及用于密封邻接结的装置。 单独的衬板可以容易地移除用于修理或更换,而不拆卸框架和相关组件。

    • A structurally compact air-to-air heat exchanger, for a gas turbine engine of the fan bypass type, that permits a lower percentage of cooling air, than is presently needed in the art, to cool effectively the hot turbine, and its parts, of the engine. This goal is achieved, in part, by using a portion of the cool flow of fan air as a heat sink, without disturbing the flow of the fan air stream. The heat exchanger is disposed internal of the engine, and, it includes a plurality of flow tubes through which flows the hot cooling air, with the flow tubes positioned in a crossflow relationship with and to a portion of the cool flow of fan air. Three (3) variations of the preferred embodiment of the heat exchanger also are taught.
