Information
In a seventh step, compressor1 and turbine are connected via energy flow connectors,
meaning the turbine drives the compressor. The pressurized air used to operate the air cycle can be
supplied either by an electric compressor or directly by the aircraft engine.
The compressor outlet pressure depends on the turbine power, which in turn depends on the compressor outlet pressure, forming an implicit nonlinear equation loop. A suitable start value is required for this equation to be solvable.
Further documentation is available in the AirCycle package.
