Abstract: A system includes a bleed system configured to direct a bleed flow from a high pressure region to a low pressure region. The bleed system includes a valve configured to control the bleed flow through the bleed system and a staged bleed conduit configured to incrementally depressurize the bleed flow. The staged bleed conduit includes an inlet coupled to the valve, a first stage configured to depressurize the bleed flow that is coupled to the inlet, a second stage configured to depressurize the bleed flow that is coupled to the first stage, and an outlet coupled to the second stage. The outlet is configured to direct the bleed flow to the low pressure region. The inlet, the first stage, the second stage, and the outlet are disposed along parallel axes.

Abstract: A diffuser assembly for a ventilation system is disclosed herein. The diffuser assembly may include a boundary defining an interior of the diffuser assembly. The diffuser assembly also may include at least one inlet to the interior of the diffuser assembly. The at least one inlet to the interior of the diffuser assembly may be in fluid communication with at least one ventilation fan. Moreover, the diffuser assembly may include an outlet from the interior of the diffuser assembly. The outlet from the interior of the diffuser assembly may be in fluid communication with an engine enclosure. In this manner, the outlet from the interior of the diffuser assembly may be configured to provide a flow of ventilation air from the at least one ventilation fan as a substantially uniform flow of ventilation air within the engine enclosure.
