WIPO Patent Application WO/2018/093627
Kind Code:
A3
Abstract:
An assembly comprises a cooling chamber (102) disposed inside an airfoil (100) of a turbine assembly. The cooling chamber (102) is configured to direct cooling air inside of the airfoil (100). The assembly includes an impingement hole (104) disposed inside the airfoil (100) and fluidly coupled with the cooling chamber (102). The impingement hole (104) is configured to direct at least some of the cooling air out of the cooling chamber (102). The assembly also includes a double impingement slot cap assembly (106) that is coupled with the airfoil (100). The double impingement slot cap assembly (106) forms a cover over the impingement hole (104) and is configured to direct the cooling air exiting the cooling chamber (102) in the airfoil (100) through the impingement hole (104) along one or more exterior surfaces (114, 116) of the airfoil (100).
