초록 ▼

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.

대표청구항 ▼

A combustion chamber for a gas-turbine engine having a generally annular outer case, a generally annular inner case spaced therefrom and oxidizer inlet means to allow oxidizer to pass into the space between the inner and outer cases, the combustion chamber comprising: a) a dome cowl member having a generally annular configuration and defining at least one opening to allow oxidizer in the space between the inner and outer case to pass through; b) first attachment means to attach the dome cowl member to the inner and outer cases such that the dome cowl member is located in the space between the inner and outer cases, wherein the first attachment means comprises: i) at least one locating hole defined by the dome cowl member; ii) at least one pin member attached to and extending inwardly from the outer case so as to engage the at least one locating hole; and, iii) a flexible member extending between the dome member and the inner case; c) first wall means forming an outer wall of the combustion chamber; d) second wall means forming an inner wall of the combustion chamber; e) third wall means forming an upstream end wall of the combustion chamber; f) second attachment means to attach the first and second wall means to the third wall means; g) third attachment means to releasably attach the third wall means to the dome cowl member such that the first, second and third wall means may be detached from the dome cowl member while the dome cowl member remains attached to the inner and outer cases; h) at least one fuel injection nozzle located between the dome cowl member and the third wall means; i) a fuel supply line operatively connected to the at least one fuel injector nozzle to supply fuel thereto and passing through the at least one opening in the dome cowl member; j) fourth attachment means to releasably attach the first wall means to the outer case; and, k) fifth attachment means to releasably attach the second wall means to the inner case.
