Title: Mean line prediction method for axial flow turbine efficiency

Journal Article · · J. Eng. Power; (United States)

A mean line loss system is described, capable of predicting the design point efficiencies of current axial turbines of gas turbine engines. This loss system is a development of the Ainley/Mathieson technique of 1951. The prediction method is tested against the ''Smith's Chart'' and against the known efficiencies of 33 turbines of recent design. It is shown to be able to predict the efficiencies of a wide range of axial turbines of conventional stage loadings to within 1 1/2 percent. 13 refs.
