摘要： A turbine blade for a turbomachine having a turbine blade wall and a fluid channel having inlet channel section on the end region leading to the cold side, outlet channel section on the end region leading to the hot side, and central channel section therebetween having a circular cross-section constant along the length. The turbine blade forms an acute angle with the surface of the turbine blade wall over which hot gas flows, and has an intermediate channel section between the inlet and central channel sections, the intermediate channel section having a larger cross-sectional area than the central channel section. The central channel section connects to the intermediate channel section forming a shoulder surface formed on a wall region of the fluid channel and, on the opposing wall region, the intermediate and central channel sections merge with one another in a linear manner with a reduced shoulder height.

摘要： A turbine includes an inner casing to which at least a stator vane of a turbine section is mountable, and an outer casing arranged around the inner casing in such a way that an outer cooling channel is formed between the inner casing and the outer casing. The outer cooling channel includes a fluid inlet through which a cooling fluid is injectable from an outer volume of the turbine into the outer cooling channel. The cooling channel includes a fluid outlet such that the cooling fluid is exhausted into an inner volume of the turbine. The fluid inlet is located with respect to the fluid outlet such that the cooling fluid inside the outer cooling channel includes a flow direction which has a component that is orientated in opposite direction with respect to a main flow direction of a working fluid of the turbine.

摘要： A component for releasing a flow of material into an environment subject to periodic fluctuations in pressure, which has: a first surface that includes an inlet; a second surface that includes an outlet; a duct formed in the component and extending from the inlet to the outlet so, when the component is in use, a flow of material received at the inlet can flow along the duct to be released at the outlet into an environment subject to periodic fluctuations in pressure. The duct includes a constriction at which it decreases in cross-sectional area as it progresses from the inlet to the outlet. This can help reduce the variation in flow rate of material released at the outlet caused by the periodic fluctuations in pressure, and may help to avoid/reduce ingestion, when the component is in use. Preferably, the component is configured to form part of a gas turbine engine.
摘要翻译：用于将材料流释放到经受压力周期性波动的环境中的部件，其具有：包括入口的第一表面; 包括出口的第二表面; 形成在部件中并且从入口延伸到出口的管道，当部件在使用中时，在入口处接收的材料流可以沿着管道流动，以在出口处被释放到环境中，从而受到周期性波动的影响压力。导管包括收缩部，当收缩部从进口到出口进入时，该收缩部在横截面积上减小。这可以帮助减少由于压力的周期性波动而在出口处释放的材料的流速的变化，并且当组件在使用时可能有助于避免/减少摄取。优选地，部件构造成形成燃气涡轮发动机的一部分。

摘要： A gas turbine engine turbine airfoil having pressure and suction sidewalls extending outwardly along a span and chordwise between opposite leading and trailing edges. A spanwise row of spaced apart bifurcated trailing edge cooling holes encased in the pressure sidewall end at corresponding trailing edge cooling slots extending chordally substantially to the trailing edge. Axially extending inter-hole partitions separate the cooling holes. An inlet between adjacent pairs of the inter-hole partitions includes a divergent inlet section. An axial intra-hole partition bifurcates the cooling hole into diverging upper and lower diverging sections downstream and aft of the divergent inlet section. A forward end of the intra-hole partition divides an aft end of the divergent inlet section into upper and lower inlet flowpaths leading to the upper and lower diverging sections leading into the trailing edge cooling slots.
