Abstract
A vane assembly for use within a gas turbine engine has a main vane portion with an internal cavity A cavity insert is located within the cavity close to the wall to define transpiration cooling paths. Cooling air leaves the insert through apertures directed at the wall to produce impingement cooling. The transpiration cooling paths are extended back to the trailing edge by means of a fairing The use of a fairing in addition to the insert allows more complicated cavity shapes to be filled.
