Abstract
A deswirl system for a gas turbine engine includes a deswirl shroud, and at least one deswirl vane having a leading end and a trailing end. The deswirl system includes a deswirl hub spaced apart from the deswirl shroud by the at least one deswirl vane. The deswirl hub includes a hub body that extends at a first angle and a hub extension that extends beyond the trailing end of the at least one deswirl vane. The hub extension extends from the hub body at a second angle, and the first angle is different than the second angle.
Claims19
A deswirl system for a gas turbine engine, comprising:
- a deswirl shroud;
- at least one deswirl vane having a leading end and a trailing end;
- and
- a deswirl hub spaced apart from the deswirl shroud by the at least one deswirl vane, the at least one deswirl vane coupled to the deswirl shroud and the deswirl hub such that the deswirl shroud is radially outboard of the deswirl hub, the deswirl hub including a hub body that extends at a first angle and a hub extension that extends beyond the trailing end of the at least one deswirl vane and beyond an end of the deswirl shroud, the hub extension extending from the hub body at a second angle, and the first angle is different than the second angle.
A gas turbine engine, comprising:
- a diffuser;
- a combustor downstream from the diffuser in a direction of a working fluid flow through the gas turbine engine;
- and
- a canted deswirl system downstream from the diffuser and upstream from the combustor, the canted deswirl system including a deswirl shroud, at least one deswirl vane and a deswirl hub spaced apart from the deswirl shroud by the at least one deswirl vane, the deswirl hub including a hub body that extends at a first angle relative to the diffuser, the hub body includes a first hub end opposite a second hub end, the second hub end is downstream from the deswirl shroud and includes a hub extension that extends from the second hub end beyond the deswirl shroud, the hub extension extending from the hub body at a second angle, the second angle is greater than the first angle and the second angle is based on a distance defined between the second hub end and a centerline of a quench hole associated with the combustor.
