wind vane
1.You who travel with the wind, what weather-vane shall direct your course?
3.On the basis of a series of plane cascade wind tunnel test results the aerodynamic characteristics of axial-flow compressor intlet guide vanes with a variable trailing edge have been determined. As a result, ascertained is the necessary correction to be applied to the deviation angle of the variable trailing edge inlet guide vane when calculated as per Carter formula and also its proper application range.
