Abstract

A gas turbine engine hybrid outer guide vane heat exchanger includes a circular row of fan outlet guide vanes, at least some of the fan outlet guide vanes being networked guide vane heat exchangers including heat exchangers within fan outlet guide vanes and guide vane heat exchangers fluidly interconnected both in series and in parallel. Group may include three or more of the guide vane heat exchangers fluidly connected both in series and in parallel. Two or more serial sets of the networked guide vane heat exchangers in the hybrid group may each include two or more of guide vane heat exchangers connected in series and two or more serial sets connected in parallel. First and second groups of the networked guide vane heat exchangers may include first and second groups for cooling engine lubrication system and/or integrated drive generator.
