摘要： A compressor impeller has a ring-shaped shroud band which is mounted at blade tips, each blade tip being enclosed in an identical radially slidable manner by a guide block, and the guide blocks being fastened to the shroud band. As a result, a narrow sealing gap and thus lower aerodynamic losses can be implemented than in conventional compressors, and the different centrifugally and thermally induced expansions of the blade and of the shroud band can be compensated.

摘要： A rotor of a turbomachine includes blades having an improved blade root configuration for anchoring and centering the blade roots in axial slots of the rotor disk. Each blade root includes two portions or sections, namely a serrated section that has a single bilaterally uniformly shaped serration, and a terminal portion that has rounded surfaces and a narrower cross-section than the serrated root section. The serrated section provides anchoring against centrifugal forces. The terminal portion provides the predominant centering effect, for which it is radially movably received and located in a recess provided in the bottom of the slot. The special root configuration substantially avoids misfit and centering problems associated with manufacturing variances, whereby the blades and blade roots can be made of lightweight engineering materials.
摘要翻译：涡轮机的转子包括具有改进的叶片根部构造的叶片，用于将叶片根部固定和定心在转子盘的轴向槽中。每个叶片根部包括两个部分或部分，即具有单个双边均匀形状的锯齿状的锯齿状部分，以及具有圆形表面和比锯齿状根部部分更窄的横截面的端部部分。锯齿部分提供了抵抗离心力的锚定。端子部分提供主要的定心作用，其可径向移动地容纳并位于设置在槽底部的凹槽中。特殊的根结构基本上避免了与制造方差有关的失配和对中问题，由此叶片和叶片根部可以由轻质工程材料制成。

摘要： A hot gas overheat protection device is provided for gas turbine engines and the like. An outer metal wall having cooling air supplied through cooling holes therethrough from the outside is shielded from hot gas flow by the provision of highly temperature resistant lining wall elements spaced from the metal wall. A thin metal skin is provided between the metal wall and the wall elements defining intermediate spaces communicating with cooling air ports in the metal wall. The thin metal skin has a melting point equal to or lower than that of the metal wall so as to provide for fusion or rupture of the thin metal skin in the event the insulating wall elements are locally ruptured, whereby the cooling air is provided through the cooling air ports in a direction against the flow of hot gases to thereby mitigate the effects of the rupture and protect the metal wall.

At least three elements (20, 21, 22) are located one on top of the other in a sandwich structure, are joined together at least in sections by diffusion welding and are then superplastically formed by expansion in such a way that a first element (20) forms a first external wall of the hollow blade to be produced, a second element (22) forms a second external wall of the hollow blade to be produced and a third element (21) forms a central element running between the two external walls of the hollow blade to be produced. At least one nick-minimizing structure is introduced into the first element (20) and the second element (22), which form the two external walls of the hollow blade to be produced, before said elements are arranged together with the third element (21) in the sandwich structure.
