초록

A passive cooling system for aircraft auxiliary power units having an intake duct extending between an inlet opening and the compartment in which the auxiliary power unit is positioned. An inlet scoop is positioned in the intake duct for diverting a portion of the airflow in the intake duct through an outlet in a wall of the intake duct. A vacuum duct is positioned near an oil cooler for the auxiliary power unit, and an aspirator is operatively positioned between the vacuum duct and an exhaust passage of the auxiliary power unit. The aspirator creates a ...
