Initial Experience with Emulsified Fuels at AVCO Lycoming 670366

This paper discusses the major effects observed in feasibility testing of three emulsified fuels in several gas turbine combustors, fuel controls, and fuel system component parts, and in three Avco Lycoming gas turbine engine models. Engine operation was essentially unaffected at power levels normally used for low altitude flight, but combustion was inhibited at starting and at altitude conditions. The fuel controls performed reasonably well, but showed that modifications will be required for reliable long term operation.
