Abstract
A fan is disposed at an intake of a nacelle, and a gas turbine is contained within a first portion of the nacelle. The gas turbine includes compressor, combustor, and turbine stages through which a core stream of gas passes past the fan and past the compressor, combustor, and turbine stages. A first heat exchanger is disposed in a second portion of the nacelle, where a fan stream passes through the second portion of the nacelle. A first switching valve receives gas from the fan stream and directs the received gas to a second switching valve or the turbine stage. The second switching valve directs gas to a boost compressor and receives gas from the first switching valve or a high pressure bleed from the compressor stage. A third switching valve receives gas from the boost compressor and directs compressed gas to the first heat exchanger or the turbine stage.
