Abstract
An engine core includes a compressor section and a core flowpath. The compressor section includes first and second compressor rotors. The core flowpath extends across the first compressor rotor and the second compressor rotor between an inlet into the core flowpath and an exhaust from the core flowpath. An air system includes an eductor, a first bleed port, a second bleed port, a first passage and a second passage. The eductor includes a nozzle disposed in the second passage. The first bleed port is disposed along the core flowpath at a downstream end of the first compressor rotor. The first bleed port fluidly couples the core flowpath to the first passage and the second passage in parallel. The second bleed port is disposed along the core flowpath at a downstream end of the second compressor rotor. The second bleed port fluidly couples the core flowpath to the nozzle.
