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.

Abstract: A seal plate for an air cycle machine includes a substantially disk-shaped body having a first side configured to be coupled to a compressor housing of the air cycle machine and a second side configured to be coupled to a turbine housing of the air cycle machine. The seal plate also includes a timing pin slot configured to align the first side of the seal plate with the compressor housing. The seal plate further includes a plurality of fastener holes distributed radially in an asymmetric pattern. The plurality of fastener holes includes an alignment fastener hole configured to align the second side of the seal plate with the turbine housing. An angular offset between the alignment fastener hole and the timing pin slot is about 38.45 degrees.
