摘要： An exhaust diffuser for a gas turbine comprises an annular duct (1). A row of struts (6) is arranged in the duct. In a region downstream of the trailing edges (TE) of the struts (6), the cross-sectional area of the duct decreases to a local minimum (M) and then increases again towards the outlet end (3) of the duct. Thereby the gas flow is locally accelerated downstream of the struts. This stabilizes the boundary layer of the flow in this region and leads to a marked increase in pressure recovery for a wide range of operating conditions.
摘要翻译：燃气轮机的排气扩散器包括环形管道（1）。一排支柱（6）布置在管道中。在支柱（6）的后缘（TE）下游的区域中，管道的横截面面积减小到局部最小值（M），然后再次朝管道的出口端（3）增加。因此，气流在支柱的下游局部加速。这使得该区域中的流动的边界层稳定，并且在宽范围的操作条件下导致压力恢复的显着增加。

摘要： An augmenter includes at least one igniter (30) which provides a uniform ignition within the augmenter. The igniter is secured to an igniter housing (82) with a self-locking nut (54) and each igniter includes a biasing mechanism (60) which biases the igniter against the augmenter. Biasing the igniter against the augmenter ensures that each igniter tip (42) is maintained at a proper immersion depth within the augmenter during gas turbine engine operation. Additionally, the igniter includes an alignment support boss (70) to ensure that the igniter tip is properly aligned within the augmenter as the igniter is attached to the augmenter.

摘要： Determining the thrust of an engine such as a jet engine. Locations on an engine trunnion at which the most repeatable strain occurs during use are determined and a strain gauge is located. The determination of the location or locations of most repeatable strain involves applying different strains or different types of strain on the trunnion, constraining movement of the trunnion and determining thermal properties of the trunnion. FEM is used.

摘要： A gas turbine engine exhaust panel mounting system comprising a panel (102), a casing (104) and an attachment assembly (100) for removably connecting the panel (102) to the casing (104) comprises a retaining portion (110), a clamping portion (120), and a 'C'-shaped connecting link (130). The connecting link (130) has a first attachment portion (132) and an opposite second attachment portion (134) with the first (132) and second attachment portions (134) being connected to one another by a centre portion (136). Each of the first (132) and second attachment portions (134) is substantially parallel to one another and extends in the same direction from respective ends of the centre portion (136). The first attachment portion (132) is fixedly connected to the casing (104) by the clamping portion (120), and the second attachment portion (134) is slidingly connected to the panel (102) by the retaining portion (110).
