Abstract
A nozzle cover for a combustor of a combination fuel gas turbine engine is cast as a one-piece integral part requiring machining only for holes, sealing surfaces and threads. The nozzle cover cross section is generally a portion of an ellipsoid in order to maximize strength for a given amount of material. An interface between the nozzle cover and each of a plurality of combination fuel nozzles employs a single threaded opening accommodating two of a required three nozzles. The third nozzle in each combination fuel nozzle is accommodated in threads formed in a stepped wall in the nozzle cover.
