A mounting system for a stator vane assembly is disclosed for mounting a vane and its cooling system to minimize the thermal and mechanical stresses imparted to the vane structure. Platforms are attached to opposite ends of the vane, which has a hollow interior and a cooling gas distributor located within the interior of the vane. One end of the cooling gas distributor is also fixedly attached to one of the vane platforms, while the opposite end of the cooling gas distributor is attached to a casing, not to the opposite vane platform. Spaces are defined between the cooling gas distributor and the vane platform, as well as the casing and the vane platform. A gas inlet sleeve may be attached to the cooling distributor and serve as its attachment to the external casing. The gas inlet sleeve extends through an opening in the vane platform which may have a greater diameter than that of the sleeve in order to provide a cooling passage interconnecting the spaces between the vane platform and the cooling gas distributor, and the vane platform and the casing.
