Turbine vane assembly with integrally cast cooling fluid nozzle |
摘要 |
A gas turbine engine having a turbine vane assembly including an integrally cast cooling fluid nozzle is disclosed. Various construction details are developed which disclose a cooling fluid nozzle including a flow passage having an exit and a wall. In one embodiment, the wall includes an angled leading edge which mates with a circumferentially adjacent trailing edge of an adjacent wall. The leading edge is tapered such that in a most open position of the turbine vane assembly the leading edge and the trailing edge circumferentially align. In a most closed position of the turbine vane assembly, the angled leading edge aligns with the trailing edge such that a step down is created in the circumferentially directed flow of the sealed cavity. The plurality of wall thereby produce a waterfall arrangement within the sealed cavity to reduce the windage losses.
