ABSTRACT:
To predict the rate of flow of cooling fluid (gas) through a passage system in a proposed airfoil during operation of a Jet engine, a full size model of the passage system is prepared. The flow of air or other gas is conducted through the model of the passage system. The characteristics of the flow of air or gas through the model of the passage system is determined to enable the characteristics of the flow of cooling fluid through the passage system in the proposed airfoil to be predicted. The model of the cooling fluid passage system in the proposed airfoil is formed by covering the pattern with a layer of metal. The pattern is removed from the covering to form a passage system having a configuration corresponding to the configuration of the cooling fluid passage system in the proposed airfoil.
