    • A cooling system for the fillet of a turbine blade is provided. The blade includes an airfoil transitioning to a platform having a flow path surface. The transition region is defined by a fillet. A cooling passage is formed in the platform and extends about at least a portion of the periphery of the airfoil. The cooling passage is located proximate to the flow path surface and is substantially aligned with at least a portion of the fillet. Coolant is delivered to the passage by a supply hole, which can reduce the temperature in the fillet region. As a result, thermal gradients in the fillet region can be minimized, which can reduce thermal stresses. An exhaust hole extends between the passage and the flow path surface of the platform. Thus, coolant discharged from the exhaust holes enters the flow path of the turbine.
    • 提供了一种用于涡轮叶片的圆角的冷却系统。 叶片包括转变到具有流动路径表面的平台的翼型件。 过渡区域由圆角定义。 冷却通道形成在平台中并围绕翼型的周边的至少一部分延伸。 冷却通道位于流路表面附近,并且基本上与圆角的至少一部分对齐。 冷却液通过供应孔输送到通道,这可以降低圆角区域的温度。 因此,可以最小化圆角区域的热梯度,这可以降低热应力。 排气孔在平台的通道和流动通道表面之间延伸。 因此,从排气孔排出的冷却剂进入涡轮机的流路。

    • A fuel injector in a combustor apparatus of a gas turbine engine. An outer wall of the injector defines an interior volume in which an intermediate wall is disposed. A first gap is formed between the outer wall and the intermediate wall. The intermediate wall defines an internal volume in which an inner wall is disposed. A second gap is formed between the intermediate wall and the inner wall. The second gap receives cooling fluid that cools the injector. The cooling fluid provides convective cooling to the intermediate wall as it flows within the second gap. The cooling fluid also flows through apertures in the intermediate wall into the first gap where it provides impingement cooling to the outer wall and provides convective cooling to the outer wall. The inner wall defines a passageway that delivers fuel into a liner downstream from a main combustion zone.

    • In a gas turbine engine having a laybrinth seal between an annular rotor and stator therein, in which the stator is surmounted by a honeycomb structure and the rotor has a knife edge which is mounted to rotate in close annular proximity with said honeycomb structure, an improvement is provided wherein such labyrinth seal has a layer of abradeable coating atop the honeycomb structure for the rotor knife edge to rotate proximate thereto and to rub in, without substantially damaging the knife edge nor the honeycomb structure. In one embodiment the layer of abradeable coating is mounted on a metalic foil which is mounted in turn, atop the honeycomb structure. The abradeable coating thus provided, is more yieldable and less damaging to a rotor knife edge than is the honeycomb structure of the prior art, to better preserve rotor and stator and thus the labryrinth seal. Because of such protection, the rotor knife edge can be thinner and of lighter weight and the honeycomb structure can be made of larger cell sizes, again resulting in weight savings for each lab seal, which can have one or a plurality of rotor (knife edge)-stator pairs. Further, the abradable coating seals the top of the honeycomb structure and thus blocks air flow into the honeycomb cells beneath and behind the knife edge and thus reduces losses in seal efficiency.
    • 在具有在其中的环形转子和定子之间具有底孔密封的燃气涡轮发动机中,其中定子被蜂窝结构覆盖,并且转子具有安装成与所述蜂窝结构紧密环接地旋转的刀刃,改进 其中这种迷宫式密封件具有在蜂窝状结构顶部的可磨蚀涂层,用于转子刀刃在其附近旋转并摩擦,而基本上不损坏刀刃和蜂窝结构。 在一个实施方案中,可磨蚀涂层是安装在依次安装在蜂窝结构顶上的金属箔上的。 如此提供的可磨损涂层比现有技术的蜂窝结构更可屈服并且对转子刀刃的损伤较小,以更好地保持转子和定子,从而更好地保持了实验室密封。 由于这样的保护,转子刀刃可以更薄和更轻的重量,并且蜂窝结构可以由更大的电池尺寸制成,这再次导致每个实验室密封件的重量节省,其可以具有一个或多个转子(刀刃 )-stator对。 此外,可磨损涂层密封蜂窝结构体的顶部,从而阻挡在刀刃下方和后方的进入蜂窝状电池的空气流,从而减少密封效率的损失。
