POWER AUGMENTATION FOR AN AIR CYCLE MACHINE OF AN ENVIRONMENTAL CONTROL SYSTEM

摘要

A system (100) that comprises a nozzle arrangement (200;300;400) is provided. The nozzle arrangement (200;300;400) includes at least one nozzle (205;405) configured to supply a medium (203) at a nozzle flow rate to a fan (149) of an air cycle machine (140). The nozzle flow rate provides a pneumatic power assist or a power augmentation to a fan (149) of an air cycle machine (140). The power augmentation, in accordance with the nozzle flow rate, reduces a need for a flow across a turbine (145) of the air cycle machine (140).
