AUXILIARY HYDRAULIC POWER GENERATION SYSTEM

摘要

An auxiliary hydraulic power generation system includes a first spool including a turbine. A fan is coupled to the first spool, the fan operable to drive the first spool in a windmill condition in which the turbine fails to provide rotational drive to the fan. An auxiliary variable displacement hydraulic pump is selectively driven by the first spool in the windmill condition to augment a hydraulic power source.
