摘要： A combustion chamber for a gas-turbine engine is disclosed in which the walls defining the combustion chamber may be easily attached to and removed from the engine structure. A dome member is attached to the engine structure such that it partially encloses the fuel injector nozzle in an upstream direction. The shape of the dome-member is such that it splits the incoming oxidizer flow into inner and outer flows which pass along the inner and outer sides of the combustion chamber. The inner and outer walls of the combustion chamber may be attached to an upstream end wall of the combustion chamber such that this assembly is removable as a unit from the dome member. The inner and outer walls, as well as the end wall, are releasably attached to the dome member such that the assembly can be removed from the gas-turbine engine without the necessity of removing or displacing the fuel injector nozzles or the dome member. Alternatively, the end wall of the combustion chamber is fixedly attached to the dome member while the inner and outer walls of the combustion chamber are releasably attached to the end wall. This enables the inner and outer walls to be separately removed from the gas-turbine engine, again without disturbing the fuel injector nozzles or the dome member.
摘要翻译： 公开了一种用于燃气涡轮发动机的燃烧室，其中限定燃烧室的壁可以容易地附接到发动机结构并从发动机结构中移除。 穹顶构件附接到发动机结构，使得其沿上游方向部分地包围燃料喷射器喷嘴。 圆顶构件的形状使得其将进入的氧化剂流分解成沿燃烧室的内侧和外侧通过的内部和外部流动。 燃烧室的内壁和外壁可以附接到燃烧室的上游端壁，使得该组件作为一个单元可从圆顶构件移除。 内壁和外壁以及端壁可释放地附接到圆顶构件，使得组件可以从燃气涡轮发动机移除，而不需要移除或移动燃料喷射器喷嘴或穹顶构件。 或者，燃烧室的端壁固定地附接到圆顶构件，而燃烧室的内壁和外壁可释放地附接到端壁。 这样可以使内壁和外壁分别从燃气涡轮发动机移除，同时不会干扰燃料喷射器喷嘴或穹顶构件。

摘要： A separator for an annular gas turbine engine combustion chamber is disclosed having a plurality of separator segments arranged in a generally annular configuration to form an annular separator extending from an upstream end wall of a combustion chamber into the combustion chamber so as to separate first and second combustion zones within the combustion chamber. Each of the separator segments has a hollow interior defined by a front wall, an outer wall, an inner wall which has at least a portion tapering or converging towards the outer wall in a direction extending away from the front wall, and first and second sides. The sides define an array of holes communicating with the hollow interior, the positioning of the array of holes on a first sides being different from that of the array of holes on the second sides such that the axes of the holes are out of alignment with each other. The first sides of one separator segment is positioned adjacent to, but spaced apart from a second sides of an adjacent separator segment. Since the array of holes on the first sides is out of alignment with the array of holes on the second sides, pressurized gas within the interior of the hollow segment will pass through the holes in the first and second sides and will impinge upon the adjacent sides so as to cool both the adjacent sides and the sides through which the gas passes.

摘要： A procedure for igniting a combustion chamber of a turbine engine, the chamber being fed with fuel by injectors and including an igniter mechanism igniting the fuel injected into the chamber. The procedure includes an initial stage during which fuel is injected into the chamber at a constant rate while simultaneously exciting the igniter mechanism, and in event of non-ignition of the chamber at an end of the initial stage, a second stage during which a rate at which fuel is injected is increased rapidly by 20% to 30%.
