초록

A two spool environmental control system includes a low pressure spool subsystem having a low pressure turbine. A high pressure spool subsystem is in air flow communication with the low pressure spool subsystem, while the high pressure spool subsystem is capable of conditioning compressed air prior to the low pressure spool subsystem conditioning the compressed air. The high pressure spool subsystem includes a high pressure turbine which is mechanically operable independently of the low pressure turbine.

청구항

[ We claim:] [1.] A method for conditioning water vapor bearing compressed air for supply as conditioned air, comprising the steps of:using a high pressure spool subsystem including a high pressure turbine and a compressor;using a low pressure spool subsystem downstream of and in air flow communication with said high pressure spool subsystem, said air flow communication being in the absence of rotating engagement between said subsystems, and said low pressure subsystem including a low pressure turbine; andflowing substantially all of said compressed air ...
