Cooled vane

摘要

A cooled vane suitable for a gas turbine engine is provided with an internal chamber which is fed with cooling air from the radially inner and outer ends of the vane. Cooling air supplied to the radially inner end of the vane is at a higher pressure than that supplied to the radially outer end. In order to ensure effective cooling of the vane a chordwise extending baffle is provided within the chamber to divide the chamber into radially inner and outer portions. The baffle is so configured as to permit a limited flow of cooling air from the radially inner chamber to the radially outer chamber. This facilitates effective cooling of the aerofoil of the vane in the region of the baffle.
