    摘要： A method for distributing fuel within a gas turbine engine is provided. An augmentor is provided which includes a plurality of vanes. Each vane includes a pair of side walls, an aft wall, and a plurality of fuel apertures and pressurized gas apertures extending through the side walls. At least one of the pressurized gas apertures is positioned adjacent and forward of all fuel apertures at a particular position. At least one fuel distributor is provided in each vane. Fuel admitted into the fuel distributors flows into the core gas path in a direction substantially perpendicular to the core gas path. Gas admitted into the vanes at a pressure higher than that of the core gas flow, flows a distance into the core gas path in a direction substantially perpendicular to the core gas path. Fuel is selectively admitted into the fuel distributors when the augmentor is enabled. Pressurized gas entering the core gas path forward of the fuel creates a low velocity wake that enables the fuel to distribute circumferentially.

    摘要翻译： 提供了一种用于在燃气涡轮发动机内分配燃料的方法。 提供了一种包括多个叶片的增压器。 每个叶片包括一对侧壁，后壁和多个燃料孔和延伸穿过侧壁的加压气体孔。 加压气体孔中的至少一个定位在特定位置处所有燃料孔附近和向前。 在每个叶片中设置至少一个燃料分配器。 进入燃料分配器的燃料沿着与核心气体路径基本垂直的方向流入核心气体路径。 气体以比核心气体流量高的压力进入叶片，在与核心气体路径基本垂直的方向上流入核心气体通路的距离。 当增强器启用时，燃料被选择性地进入燃料分配器。 进入燃料向前的核心气体路径的加压气体产生低速尾流，使燃料能够周向分布。

    摘要： A bypass air valve is provided comprising a liner, a strap, and apparatus for selectively actuating the valve. The liner includes an inner surface, an outer surface, a plurality of first regions, and a plurality of second regions. Each first region includes a plurality of first apertures. The strap includes a plurality of openings and a plurality of third regions. The third regions include a plurality of second apertures. The valve may be selectively actuated into an open position where the first regions are in communication with the openings, and the third regions are in communication with the second regions. The valve may be selectively actuated into a closed position where the first regions are in communication with the third regions, and the second regions are in communication with the openings. The flow path through the first and second apertures in the closed position impedes flow substantially more than the flow path through the first apertures and the openings in the open position, thereby effectively closing bypass air flow through the valve in the closed position.

    摘要： A flameholder for an augmentor rotates about an axis radially positioned with a turbine engine. The flameholder is in a streamlined position when the augmentor is not operating to minimize pressure loss and radar cross-section and a turbulent position when the augmentor is operating. A linkage connects the flameholder to an actuator to control the rotational position of the flameholder on the axis. Bypass airflow from the fan cools the flameholders and linkages. The length of the linkages can be varied from one flameholder to another to create asymmetric heat release within the augmentor to avoid screech.

    摘要： Systems and methods reducing thermo-acoustic coupling of a gas turbine engine augmentors are provided. In this regard, a representative method includes: determining acoustic resonances and heat release phase relationships associated with the augmentor; and determining relative axial positions of a fuel injector and a flame holder of the augmentor that result in reduced thermo-acoustic coupling of the augmentor during operation.
