abstract

A design for an impingement cooled and vented silicon nitride turbine vane for potential application to the Pratt & Whitney/Turbo Power and Marine FT8 aeroderivative stationary turbine is presented. The final design reduced the cooling air requirement for this first stage turbine vane by several percent of total core flow, compared to the current cobalt alloy bill of materials airfoil. Careful attention to achieving uniform internal and external temperature distributions, and design of the trailing edge vests, were necessary to ensure a design having a high Probability of Survival. The NASA CARES code was used to determine probabilistic fast fracture reliability of the silicon nitride airfoil.
