Abstract
A hollow stator vane for a turbine is provided with separate forward and aft inserts 26 and 32 with the forward insert providing impingement cooling of the vane walls while the aft insert is closely fitted into the vane internal cavity to provide closely defined channel widths between the insert and facing walls of the vane, the aft insert also including means functioning during operation to ensure the maintenance of the closely defined channel widths, the coolant air admitted to the inserts functioning first for impingement cooling, then channel flow cooling along the aft insert, and then channel flow cooling of the trailing edge 18 through an exit slot.
