Abstract

A component for use in releasing a flow of material into an environment subject to periodic fluctuations in pressure. The component has: a first surface that includes an inlet (32); a second surface that includes an outlet (34); a duct (30) that is formed in the component and extends from the inlet to the outlet so that, when the component is in use, a flow of material received at the inlet is able to flow along the duct to be released at the outlet into an environment subject to periodic fluctuations in pressure. The duct includes a constriction (36) at which the duct decreases in cross-sectional area as it progresses from the inlet to the outlet. This can help to reduce the variation in flow rate of material released at the outlet caused by the periodic fluctuations in pressure, and may further help to avoid/reduce ingestion, when the component is in use. Preferably, the component is configured to form part of a gas turbine engine.
