Abstract
An air intake system includes a ram air cooling circuit, an air compression system, and an energy recovery system. The cooling circuit includes an inlet, an outlet, and a heat exchanger. The outlet is downstream from the inlet. The heat exchanger is between the inlet and the outlet. The compression system includes an inlet duct, a rotary machine, and an outlet duct. The inlet duct is downstream from the cooling circuit inlet. The rotary machine includes a shaft mechanically connecting a first compressor section, a second compressor section, a motor section, and a turbine section. The first compressor section is downstream from the inlet duct and upstream from the heat exchanger. The second compressor section is downstream from the heat exchanger. The outlet duct is downstream from the second compressor section. The energy recovery system includes a compartment downstream from the outlet duct and upstream from the turbine section.
