Abstract
An aircraft environmental control system includes a tank holding liquid fuel, a heat exchanger, a first rotary machine, and a second rotary machine. The heat exchanger includes a cold side flow path downstream from the tank to vaporize the fuel using hot fluids from the aircraft. The heat exchanger includes a first hot side flow path and a second hot side flow path to cool the hot fluids. The first rotary machine includes a first compressor with a first impeller upstream from the second hot side flow path. The first rotary machine includes a first shaft tied to the first impeller and a first motor, which rotates the first impeller. The second rotary machine includes a second compressor with a second impeller downstream from the first compressor section. The second rotary machine includes a second shaft tied to the second impeller and a second motor, which rotates the second impeller.
