Abstract
An aircraft propulsion system includes a turbocompressor unit, an engine exhaust assembly, and a tube assembly. The turbocompressor unit includes a compressor, a turbine, a turbocompressor rotational assembly, and a static structure. The static structure forms a first cavity and a second cavity. The engine exhaust assembly includes an annular scroll disposed between the first cavity and the second cavity. The annular scroll includes a scroll body and a plurality of hollow stator vanes. The plurality of hollow stator vanes is disposed within the flow channel. The tube assembly includes a tubular body. The tubular body extends through one of the plurality of hollow stator vanes between and to the first cavity and the second cavity. The tubular body forms an internal passage extending from the first axial tube end to the second axial tube end. The internal passage connects the first cavity in fluid communication with the second cavity.
