Abstract: A diffuser and deswirl system associated with an engine includes a throat ring defining a plurality of passages spaced apart about a perimeter of the throat ring, a plurality of pockets and a support flange. Each passage of the plurality of passages is to receive a working fluid and each pocket of the plurality of pockets is defined about a portion of a respective passage of the plurality of passages. The diffuser and deswirl system includes a plurality of conduits, with each conduit including a first conduit end and a second conduit end opposite the first conduit end. The first conduit end of each conduit is received within and coupled to the pocket of a respective one of the plurality of passages to receive the working fluid, and each conduit includes a mating feature defined between the first conduit end and the second conduit end coupled to the support flange.

Abstract: A turboprop engine system for an aircraft includes an engine, a propeller, and a gear train coupled to and configured to provide power from the engine to the propeller at a predetermined gear reduction. The engine system also includes a gearbox that houses at least part of the gear train. The gearbox includes a gearbox flow structure and an inlet flow structure that is removably attached to the gearbox. The inlet flow structure and the gearbox flow structure cooperate to define an inlet flow passage to the engine. The inlet flow passage has an upstream end and a downstream end that are cooperatively defined by the inlet flow structure and the gearbox flow structure. The upstream end is configured to receive an airstream that is directed along the inlet flow passage to the downstream end and toward the engine.
