Abstract
A hollow thermally-conditioned turbine stator nozzle 12 is set forth to distribute and guide combustion gases from a forward inlet 15 to the turbine rotor blades 18. The nozzle includes a plurality of vanes 20 arranged annularly in the turbine. Each vane 20 has a body 22 to guide the fluid, the body being supported by outer and inner ends 34,64. The outer and inner ends each have a forward lug 44,74 and a rear lug 46,76. A floating support is provided for the vanes and includes forward shoulders 110,136 to engage the forward lugs and prevent rearward movement of the vanes and rear shoulders 114,142 having notches 116,144 to receive and confine the tangential movement of the vanes. Each vane also includes a hollow core 152 to pass a portion of fluid and reduce thermal stresses on the vane. The vane is preferably made of silicon nitride ceramic.
