Gas turbine engine assemblies with recirculated hot gas ingestion

A gas turbine engine assembly, comprising:

• a housing including an annular duct wall that at least partially defines a mainstream hot gas flow path configured to receive mainstream hot gas flow;
• a stator assembly including a stator vane that extends into the mainstream hot gas flow path, the stator assembly further including a stationary discourager extending in a downstream direction;
• and
• a turbine rotor assembly downstream of the stator assembly and including a turbine disk and a turbine blade extending from the turbine disk into the mainstream hot gas flow path, the turbine rotor assembly further including a turbine discourager that extends in an upstream direction and is overlapped by the stationary discourager,
• the stator assembly and turbine assembly defining a turbine disk cavity with a gap adjacent the mainstream hot gas flow between the turbine discourager and the stationary discourager, the turbine disk cavity including a recirculation cavity configured to recirculate gas ingested from the mainstream hot gas flow path back into the mainstream hot gas flow path, the recirculation cavity including
• a first recirculation section adjacent the gap and configured to recirculate a first portion of the ingested gas in a first direction, the first recirculation section being at least partially formed by a first deflector extending from the turbine discourager,
• a second recirculation section adjacent the first recirculation section and configured to recirculate a second portion of the ingested gas in a second direction, the second recirculation section being at least partially formed by the first deflector extending from the turbine discourager and a second deflector extending from the stationary discourager, and
• a third recirculation section configured to recirculate a third portion of the ingested gas in the first direction, the third section being at least partially defined by the second deflector extending from the stationary discourager and a third deflector extending from the stationary discourager.
