As its title suggests, this article is devoted to developments in gas turbine fuel injection diving the past half-century. It describes in general terms the evolution of pressure atomizers front the simplex nozzle of the 1940s to the dual-orifice injector that remained in widespread use for over 20 years until it was replaced by the various forms of airblast atomizer that dominated the scene for the next three decades. The pressure nozzles described herein include simplex, duplex, dual-orifice, fall-spray, and spill-return. The inherent design flexibility of the airblast concept encouraged a wide variety of injector configurations, ranging from simple air-assist nozzles to the more sophisticated designs of today, in which part of the atomizing air is carried by the nozzle itself while the remainder flows through swirlers mounted on the combustion liner. Attention is focused on the relative merits of the various nozzle types, both pressure and airblast, in regard to their ability to satisfy stringent performance requirements while surviving formally thousands of hours in the increasingly hostile environment created by the continuing trend toward engines of higher pressure ratio, Reference is made to some new developments in atomizer design and manufacture and to the ongoing rob of the fuel injector irt finding solutions to the problems posed by ultralow-emissions combustors, many of which are required to operate near the lean extinction limit on fully premixed fual-air mixtures.
