Abstract
An air processing system for an aircraft comprising a hydrogen fuel cell. The air processing system includes an input airflow; a first and a second compressor, wherein each compressor is configured to compress the airflow in a compression stage; a first and a second turbine, wherein each turbine is configured to decompress the airflow in a decompression stage; and a first and a second shaft each configured to independently rotate. Each shaft mechanically couples one of the compressors and one of the turbines, such that torque can be transferred between the compressor-turbine pair.

An air processing system for an aircraft comprising a hydrogen fuel cell, the air processing system comprising:
- an input airflow;
- a first and a second compressor, wherein each compressor is configured to compress the airflow in a compression stage;
- a first and a second turbine, wherein each turbine is configured to decompress the airflow in a decompression stage;
- and
- a first and a second shaft each configured to independently rotate;
- wherein each shaft mechanically couples one of the compressors and one of the turbines, such that torque can be transferred between the compressor-turbine pair.
A method of processing air for an aircraft comprising a hydrogen fuel cell, the method comprising:
- providing an input airflow;
- compressing the input airflow
- in a first compression stage using a first compressor, and
- in a second compression stage using a second compressor;
- decompressing the airflow
- in a first decompression stage using a first turbine, and
- in a second decompression stage using a second turbine;
- providing a first and a second shaft, wherein each shaft is configured to independently rotate;
- and
- mechanically coupling one of the compressors and one of the turbines, such that torque can be transferred between the compressor-turbine pair.
