A gas turbine engine includes: an inlet guide vane; an inlet channel extending from a location downstream of the inlet guide vane to a stem manifold; and an outlet channel extending to an outlet port, the outlet port configured to dump anti-ice air overboard, wherein the inlet guide vane includes an anti-ice cavity in fluid communication with the inlet channel and the outlet channel such that anti-ice air, flowing from a downstream location within a core flow of the gas turbine, flows from the inlet channel, through the inlet guide vane, and to the outlet channel.

Anti-ice system for gas turbine engine and inlet guide vane

A gas turbine engine includes: a manifold arrangement; a plurality of inlet guide vanes located radially inward of the manifold arrangement, wherein each inlet guide vane of the plurality of guide vanes includes an anti-ice cavity for directing a flow of an anti-ice air; and a plurality of crossover ducts located radially inside the manifold arrangement, wherein each crossover duct of the plurality of crossover ducts provides fluid communication between two adjacent inlet guide vanes.

Manifold assembly and anti-ice system for gas turbine engine

A rotor assembly includes a first component, a second component, and a splined balance weight. The first component is arranged circumferentially around a central axis. The second component is arranged circumferentially around the central axis. The splined balance weight is located radially between the first component and the second component.
