1. An assembly for a gas turbine engine of an aircraft propulsion system, the assembly comprising:
at least one rotational assembly configured for rotation about an axis, the at least one rotational assembly includes a shaft, a bladed compressor rotor, and a bladed turbine rotor, and the shaft interconnects the bladed compressor rotor and the bladed turbine rotor;
an engine static structure including an engine case assembly, the engine case assembly extends circumferentially about the axis, and the engine case assembly surrounds the at least one rotational assembly;
a compressor including the bladed compressor rotor, and the compressor is configured to form a compressed air flow;
a combustor;
one or more compressed air loads disposed within the engine case assembly, and the one or more compressed air loads are connected in fluid communication with the compressor to receive the compressed air flow; and
a particulate separator assembly including at least one particulate separator, the at least one particulate separator is disposed outside of the engine case assembly, the at least one particulate separator are connected in fluid communication with and between the compressor and the one or more compressed air loads, and the at least one particulate separator is configured to separate particulate from the compressed air flow and direct the compressed air flow to the one or more compressed air loads,
wherein:
the engine case assembly includes an outer diffuser case and an inner diffuser case, the outer diffuser case and the inner diffuser case form an annular air plenum surrounding the combustor, the annular air plenum includes an outer plenum portion and an inner plenum portion, the outer plenum portion is disposed radially outward of the combustor, the inner plenum portion is disposed radially inward of the combustor; and
the at least one particulate separator is connected in fluid communication with the compressor through the outer plenum portion.
