Abstract: An aerofoil component of a gas turbine engine has an aerofoil portion which spans, in use, a working gas annulus of the engine. The aerofoil portion has a pressure side outer wall and a suction side outer wall, each extending from the leading edge to the trailing edge of the aerofoil portion. The aerofoil portion further has one or more main passages which extend in the annulus-spanning direction of the aerofoil portion and which receive, in use, a flow of coolant. The aerofoil portion further has one or more suction wall passages which extend in the annulus-spanning direction of the aerofoil portion and which receive, in use, a flow of coolant, each suction wall passage being bounded on opposing first sides by the suction side outer wall and an inner wall of the aerofoil portion, the inner wall separating the suction wall passages from the main passages.

Abstract: An internally cooled gas turbine engine component has a line of cooling air discharge holes, an internal cooling channel, an internal feed cavity for feeding cooling air from the channel to the discharge holes, and flow disrupting pedestals arranged in rows. A method of configuring the component includes:determining angles α and β of the directions of cooling air flow into the first and Nth rows, respectively;defining a change in angle φ of the direction of cooling air flow between rows as φ=(β−α)/N; andpositioning the pedestals such that a line extending forward from the centre of each pedestal in the ith row at an angle {α+φ(i−1)} intersects the (i −1)th row at a location which is midway between two neighbouring pedestals of the (i−1)th row, i being an integer from 2 to N.
