Abstract
An oxidizer control device for controlling the amount of oxidizer passing into a combustion chamber of a gas turbine engine. The device has first and second diaphragm assemblies located adjacent to each other at a front portion of the chamber. The first diaphragm assembly has a first, generally annular member with a plurality of circumferentially spaced apart vanes, adjacent vanes forming first oxidizer passageways therebetween, the first passageways opening through a periphery of the first member, and a second generally annular member extending around the periphery of the first member, the second member having a plurality of circumferentially spaced apart first orifices equal in number to the number of first passageways and being fixedly attached to the engine structure. The second diaphragm assembly has a third generally annular member with a plurality of circumferentially spaced apart vanes, adjacent vanes forming second oxidizer passageways therebetween, the second passageways opening through a periphery of the third member, which is fixedly attached to the engine structure and a fourth generally annular member extending around the periphery of the third member, the fourth memb…
