Abstract
An air cycle machine includes a housing, a scavenging turbine, and an ambient air fan. The housing has an exterior wall defining an overboard air inlet, an ambient air inlet, and an ambient air outlet. The scavenging turbine is arranged within the housing, is supported for rotation about a rotation axis, and is in fluid communication with the overboard air inlet. The ambient air fan is arranged within the housing, is supported for rotation about the rotation axis within the housing, and has a radially inner spoked portion and radially outer bladed portion. The bladed portion of the ambient air fan fluidly couples the ambient air inlet to the ambient air outlet and the spoked portion of the ambient air fan fluidly couples the scavenging turbine to the ambient air fan within the housing. Environmental control systems and fluid communication methods are also described.
