A gas turbine engine includes a fan (120), a compressor section (130) having at least two sequential compressors (132,134), a combustor section (140) fluidly connected to the compressor section (130), and a turbine section (150) fluidly connected to the combustor section (140). The turbine section (150) includes at least a first turbine (152), a second turbine (154) and a third turbine (156). One of the first turbine (152), the second turbine (154) and the third turbine (1 56) is a fan-drive turbine. An environmental control system air supply includes at least a first compressor bleed (136) and a second compressor bleed (138). Each of the first compressor bleed (136) and the second compressor bleed (138) are positioned upstream of a highest pressure compressor (134) of the at least two compressors. |
