ENGINE BLEED AIR DUCTING INTO HEAT EXCHANGER DUCT

A gas turbine engine (20) includes a compressor section (106), a combustor (108), and a turbine section (110). A bleed tap (116) taps air from the compressor section (106) through a bleed valve (112). The bleed valve (112) is selectively opened by a control to dump air from the compressor section (106) to a dump outlet (118). A heat exchanger duct (119) includes a duct air inlet (104) to cool a fluid in a heat exchanger (124) and a duct air outlet (122). The dump outlet (118) is within the heat exchanger duct (119).
